CL-1,CL-2 SAFETY CONSIDERATIONS Installing, starting up, and servicing this equipment can be hazardous due to system pressures, electrical components and equipment location (elevated structures, etc.). Only trained, qualified installers and service mechanics should install, start up, and service this equipment. Untrained personnel can perform basic maintenance functions such as cleaning coils, and cleaning and replacing filters. All other operations should be performed by trained service personnel. When working on the equipment, observe precautions in the literature and on tags, stickers, and labels attached to the equipment. • Follow all safety codes. • Wear safety glasses and work gloves. • Use care in handling, rigging, and setting bulky equipment. Be sure all power to equipment is shut off before performing maintenance or service. More than one disconnect may be present. PRE-INSTALLATION Moving and Storage — To transfer unit from truck to storage site, use a fork truck. Do not stack units more than 2 high during storage. If unit is to be stored for more than 2 weeks before installation, choose a level, dry storage site free from vibration. Do not remove plastic wrap or skid from unit until final installation. Rigging — All 40RM Series units can be rigged by using the shipping skid. Units are shipped fully assembled. Do not remove shipping skids or protective covering until unit is ready for final placement; damage to bottom panels can result. Use slings and spreader bars as applicable to lift unit. INSTALLATION General — Allow 21⁄2 ft at front and side of unit for service clearance and airflow. For units equipped with an economizer, refer to the accessory installation instructions for additional clearance requirements. Be sure floor, wall, or ceiling can support unit weight (Tables 1A-1F). See Fig. 1A-1C for dimensions. Uncrating — Move unit as near as possible to final location before removing shipping skid. Remove metal banding, top skid, and plastic wrap. Examine unit for shipping damage. If shipping damage is evident, file claim with transportation agency. Remove base skid just prior to actual installation. Check nameplate information against available power supply and model number description in Fig. 2. Accessories — Refer to instructions shipped with each accessory for specific information. Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

The unit can also be applied in a horizontal arrangement with return air entering horizontally and the supply air discharging horizontally. When applying the unit in a horizontal arrangement, ensure the condensate drain pan is located at the bottom center of the unit for adequate condensate disposal. See Fig. 3 for condensate connections for each unit position. Typical positioning and alternate return air locations are shown in Fig. 3. Alternate return air locations can be used by moving the unit panel from the alternate return air location to the standard return air location. LEGEND Accessory Line Alternate Air Intake and Discharge Air Intake and Discharge Fig. 3 — Typical Unit Positioning IMPORTANT: Do NOT attempt to install unit with return air entering top panel of unit. Condensate will not drain from unit. 11 Unit Isolation — Where extremely quiet operation is essential, install isolators between floor and base of unit, or between ceiling and top section of unit. Be sure that unit is level and adequately supported. Use channels at front and sides of unit for reference points when leveling. Refrigerant Piping — See Tables 1A, 1B, 1D, 1E for refrigerant pipe connection sizes. For ease in brazing, it is recommended that all internal solder joints be made before unit is placed in final position. The 40RM and 40RMQ direct-expansion units have internal factory-installed thermostatic expansion valves (TXVs), distributors, and nozzles for use with R-22. See Table 2 for part numbers. Knockouts are provided in the unit corner posts for 40RM and 40RMQ008 and 012 refrigerant piping. The 40RMQ016 unit requires additional field-fabricated piping access holes. See Fig. 4, which also lists recommended knockouts and access holes to use for each 40RM and 40RMQ unit size. Recommended fittings are listed in Table 3. The sensor bulb capillary tubes must be routed from the TXVs inside the unit through one of the piping access holes. Clamp the TXV sensor bulb on a vertical portion of the suction line, outside the unit. See Fig. 5. Refrigerant and Chilled Water Piping Access — The 40RM Series units come with standard knockouts for refrigerant and chilled water piping. These knockouts are located on both sides of the unit for installation flexibility. The standard knockouts provide sufficient access to the unit’s coils for all 40RM and some 40RMQ units, however, for 40RMQ016 and 40RMS units, additional holes must be field-fabricated to accommodate the piping. See Fig. 4 for the positions and dimensions of the additional access holes required for these units, including hole diameters and drilling dimensions. Recommended access hole use is also listed for all units. Note that Fig. 4 shows the access holes on the control-box side of the unit; this is the side of the unit with the coil headers, so it is used most often for piping access.

Do NOT mount the sensor on a trapped portion of the suction line. 40RM Series evaporator coils have a face-split design. Ensure that lower circuit of coil is first on/last off when connected to the condensing unit and/or system controls. See Fig. 6. External TXV equalizer connections are provided and factorybrazed into the coil suction manifolds. If suction line must be horizontal, clamp bulb to suction line at least 45 degrees above bottom, at approximately the 4 o’clock or 8 o’clock position. See Fig. 7. NOTE: The 40RMQ units are supplied with factory-installed thermostatic expansion valves and check valve bypasses. No extra piping connections or kits are required to install the 40RMQ with a 38AQS condensing unit in a heat pump system, however, some field supplied components may be required.

To size, design, and install chilled water piping, consult the Carrier System Design manual. See Fig. 9 for an example of a typical installation. Recommended fittings are listed in Table 3. To access 40RMS coil vents and drains, remove the unit side panel over the coil header. Vent and drain plugs are on the top and bottom of header, respectively. See the Service section for information on preventing coil freeze-up during winter. Chilled Water Piping — See Tables 1C and 1F for chilled water connection sizes. For ease in brazing, it is recommended that all internal solder joints be made before unit is placed in final position. Knockouts are provided in the unit corner posts for 40RM and 40RMQ refrigerant piping; additional field-fabricated access holes are required for 40RMS chilled water piping. See Fig. 4, which lists recommended knockouts and access holes to use for each 40RMS unit size. Fig. 9 — Typical 40RMS Chilled Water Piping 17 outlet at both ends of the unit, push drain pan down in the slots near the drain connection, and up in the slots on the opposite end. Retighten screws. The pan should have a pitch of at least 1⁄4-in. over its length toward the drain connection. Condensate Drain — Install a trapped condensate drain line to unit connection as shown in Fig. 10. The unit drain connection is a PVC stub. See Fig. 11. Some areas may require an adapter to connect to either galvanized steel or copper pipe. For these applications, install a field-supplied threaded PVC adapter. NOTE: A trap must be installed in the condensate drain line to ensure that the static pressure of fans is balanced with the water column in the drain line and that condensate can drain completely from pan. Without a trap, air can be drawn up drain line until water level in condensate pan becomes equal to static pressure created by fans, preventing complete drainage. Conditions will worsen as filters become dirty. Install clean-out plugs in trap. Pitch drain line downward to an open floor drain or sump. Provide service clearance around drain line to permit removal of unit panels. Observe all local sanitary codes. As shipped, the unit’s condensate drain pan is NOT sloped towards the drain connection. The pan slope must be changed to pitch towards the side of the unit with the drain connection. See Fig. 11. Loosen the 2 screws next to the drain Fan Motors and Drives — Motor and drive packages are factory installed in all units. The standard motor and drive packages consist of the following items: 1 — fan motor 1 — adjustable motor pulley 1 — fan pulley 1 —fan belt (40RM007-016, 40RMQ008-016, 40RMS 008-016 units) 2 —matched fan belts (40RM024-034, 40RMS024-034 units) For instructions on changing fan rotation, changing drive speeds and adjusting drives, see Pulley and Drive Adjustment in the Service section.

Rewire the motor according to the diagram plate on the motor. After reconfiguring the motor, place the sticker specifying 230-v operation (supplied in installation packet) over the 460-v sticker on the units corner post. Fan motors are factory installed on all units. Indoor-fan contactors are located in the fan contactor box behind the side access panel (see Fig. 12 and 13). Wire the thermostat to the 24-v control circuit terminal block located in the side of the fan contactor control box, according to Fig. 14 or the unit label diagram. If the air handler is part of a split system, complete the wiring from the condensing unit to the thermostat shown in Fig. 14. Power Supply and Wiring — Check the unit data plate to ensure that available power supply matches electrical characteristics of the unit. Provide a disconnect switch of size required to provide adequate fan motor starting current. See Tables 4 - 6 for unit electrical data. Install disconnect switch and power wiring in accordance with all applicable local codes. See Fig. 12-14 and the unit label diagram. For units with motor sizes less than 5 Hp (3.7 kW), connect power wiring to unit with no. 10 ring terminal. For units with motor sizes of 5 Hp (3.7 kW) or more, connect power wiring with 1⁄4-in. ring terminal.

Figure 15 shows recommended duct connection to units with 2 fans. DISCHARGE CONNECTIONS — Duct flanges are factory supplied; they are shipped inside the unit attached to the hairpin end of the coil tube sheet for field installation. Using the existing screws, install the duct flanges on the unit’s fan deck. Each fan discharge requires 2 flanges; each flange must be bent in the middle to conform to the discharge opening. See Fig. 16. After flanges are installed, connect them to the supply duct using a canvas connection to prevent vibration. It is important that this connection be properly fabricated to prevent high air friction losses and air noise. RETURN CONNECTION — When using return-air ductwork, route return-air duct to the unit’s return air inlet near the filter rack, using a canvas connection to prevent transmission of unit vibration. If the duct blocks off the unit’s access panel, provide a slip joint in the ductwork to permit removal for servicing. OUTDOOR-AIR INLET CONNECTION — Connect outdoorair inlet to field-installed accessory economizer. Refer to economizer Installation Instructions. Return-Air Filters — Type and size of filters are shown in Tables 1A-1F and are factory-supplied and installed. In all units with 2 fans, a filter replacement tool (hook) is shipped inside the unit for field use when replacing filters. See the Service section for instructions on filter element replacement. 596 Fig. 15 — Typical Fan Discharge Connections for Multiple Fan Units 22 Fig. 16 — Duct Flange Installation START-UP Fan Motor Lubrication — Fan motor supplied with unit is permanently lubricated and requires no further lubrication. Before starting unit, check the following and correct as necessary: • Is unit solidly supported? • Is fan adjusted for speed and pulley alignment? • Are pulleys, motor, and bearings securely mounted? • Are there any loose parts that will rattle or vibrate? • Is condensate drain pan pitched for correct drainage? • Are coil baffle plates tight against coil to prevent air bypass? • Are all panels securely fastened? • Are all electrical connections correct and tight? Fan Shaft Bearings — Bearings on 007-012 size units are sealed, permanently lubricated bearings that require no further lubrication. Size 014-034 units have pillow-block bearings (Fig. 17) that must be lubricated with suitable bearing grease approximately every 3 months. See Table 7 for suitable lubricants.

A split system start-up checklist is provided in the back of these instructions. LUBRICANT Prestige 42 Multifak 2 Regal AFB-2* Mobilplex EP No. 2 *Preferred lubricant because it contains rust and oxidation inhibitors. SERVICE Inspection and maintenance should be performed at regular intervals and should include the following: • Complete cleaning of cabinet, fan wheel, cooling coil, condensate pan and drain, heating coils, and return-air grille (if present). • Inspection of panels and sealing of unit against air leakage. • Adjustment of fan motor, belt, bearings, and wheels. • Cleaning or replacement of filters. • Testing for cooling/heating system leaks. • Checking of all electrical connections. Most unit service can be performed by removing one or both of the unit’s side panels. Coil cleaning or removal or insulation cleaning may require removal of a rear, top, or bottom panel, depending on the unit’s orientation. When service is completed, replace unit panels. Panels — Panels are fastened to unit frame with sheet metal screws. Fan and coil compartment must be sealed tightly after service to prevent air from bypassing the cooling coil.

Position fan wheel in center of the fan housing and tighten locking bolts. Clearance between wheel and housing should be the same on both sides. Fan Shaft Position Adjustment — Loosen setscrew or locking collar of each fan shaft bearing. Slide shaft into correct position and replace locking collar (Fig. 18). To replace locking collar, push collar up against inner face of bearing. Turn collar in direction of fan rotation until tight, and tighten setscrew. Tightening locking collar in direction of fan rotation results in further tightening of collar should setscrew work itself loose. Fan Belts — Motor mounting plate and motor support angles are slotted to permit both vertical and horizontal adjustment. Adjust belt(s) for correct deflection by loosening motor plate mounting bolts, moving motor/plate assembly forward or back, and retightening bolts. Press down on belt with one finger midway between fan and motor pulleys to check deflection. For units with motor sizes up to and including 3.7 Hp (2.76 kW), correct deflection is 3⁄16-in. (4.8 mm) For larger motor sizes, correct deflection is 1⁄8-in. (3.2 mm). See Fig. 19. NOTE: The 028 and 034 size units with 60 Hz motors are shipped with an extra set of matching belts. Use the preinstalled belts or extra belts depending on the adjustable pulley setting. If complete belt replacement is required during servicing, loosen the motor plate mounting bolts (Fig. 19), move motor/plate assembly towards fan pulley, and pull belt(s) off pulleys. Reverse the procedure with new bolts and readjust deflection. Fan Rotation — Correct fan rotation with respect to fan outlet is shown in Fig. 20. To reverse the direction of rotation of a 3-phase fan motor, reverse any 2 of the power leads. Refer to the connection diagram on the inside of motor terminal box cover for proper reversing procedure of single-phase motor. Fig. 18 — Fan Shaft Bearing Fig. 19 — Fan Motor Mounting 24 Fig. 20 — Fan Rotation Fan Pulley Alignment — Align as follows: 1. Loosen setscrews on pulleys. 2. Align pulleys visually and tighten setscrews on fan pulley to lock it in place. 3. Use the methods shown in Fig. 21 to check proper pulley alignment. 4. If pulleys are not in correct alignment, loosen the motor holddown bolts and slide the motor axially until the pulleys are aligned. 5. Tighten motor holddown bolts. Fig. 21 — Fan Pulley Adjustments Alternative freeze protection methods follow: • Circulate hot water within the water coil’s supply main or supplementary space heating. • Close off supply lines to unit and open a union or fieldsupplied drain valve in the return line. Pulley and Drive Adjustment — To obtain desired fan speed, refer to the fan motor and drive data in Tables 8A-10D and adjust fan motor pulley as follows: IMPORTANT: Draining from return line will not completely drain water from coils. 1. Remove belt from fan motor pulley after loosening motor from motor base. 2. Loosen setscrew in moveable flange of pulley. Screw moveable flange toward fixed flange to increase the fan speed and away from fixed flange to reduce speed. Before tightening setscrew, make certain that setscrew is over nearest flat surface of pulley hub (Fig. 21). After draining as much water as possible from coils, add sufficient antifreeze to prevent residual water in the coil from freezing. • Add a sufficient quantity of non-corrosive antifreeze to the entire system to prevent all water within the system from freezing. Coil Removal — Remove unit panels and corner posts as required. Disconnect coil connections and remove fastening screws. Remove coil through end or side sections of unit. Increasing fan speed produces a greater load on motor. Do not exceed rated capacity of motor. Cleaning Cooling Coil — Remove return-air filters. Remove any heavy dirt that may have accumulated on underside of coil. Coil can be cleaned more easily with a stiff brush, vacuum cleaner, or compressed air when coil is dry. If coil is wet or if water is to be used for cleaning, guard against splashing water on electrical components or damaging surrounding area. Clean coil baffles as applicable and check for tight fit to be sure air does not bypass coil. Condensate Drains — Keep condensate drains free of dirt and foreign matter. Return-Air Filters — Refer to Replacing Filters section, page 39, for filter accessibility and removal. Replace with clean filters of the sizes listed in Tables 1A-1F. Cleaning Insulation — The insulation contains an Chilled Water Coil Freeze Protection — Shut off water supply to unit. Remove side panel of unit and remove vent and drain plugs in top and bottom of coil header. Drain coil and blow out remaining water. Reinstall plugs and side panel. immobilized antimicrobial agent that helps prevent the growth of bacteria and fungi. Clean the inner surface of the insulation according to the separate maintenance instructions shipped with the unit. 25 Table 8A — Fan Motor Data, Standard Motor — English UNIT 40RM 007 208/230-1-60 Speed (rpm) 1725 Hp 1.3 Frame (NEMA) 56Y 5⁄8 Shaft Dia (in.) 208/230-3-60 and 460-3-60 Speed (rpm) 1725 Hp 2.4 Frame (NEMA) 56Y 5⁄8 Shaft Dia (in.) 575-3-60 Speed (rpm) 1725 Hp 1.0 Frame (NEMA) 56 5⁄8 Shaft Dia (in.) 230-3-50 and 400-3-50 Speed (rpm) 1425 Hp 2.4 Frame (NEMA) 56Y 5⁄8 Shaft Dia (in.) 40RM 40RMQ 40RMS 008 40RMS 010 40RM 40RMQ 40RMS 012 40RM 40RMS 014 40RM 40RMQ 40RMS 016 40RM 40RMS 024 40RM 40RMS 028 40RM 40RMS 034 1725 2.4 56Y 5 ⁄8 1725 2.4 56Y 5⁄8 — — — — — — — — — — — — — — — — — — — — — — — — 1725 2.4 56Y 5 ⁄8 1725 2.4 56Y 5⁄8 1725 2.4 56Y 5 ⁄8 1725 2.9 56Y 7 ⁄8 1725 3.7 56Y 7 ⁄8 1745 5.0 S184T 1 1 ⁄8 1745 7.5 S213T 13⁄8 1745 10.0 S215T 13⁄8 1725 2.0 56HZ 7 ⁄8 1725 2.0 56HZ 7⁄8 1725 2.0 56HZ 7 ⁄8 1725 3.0 56HZ 7 ⁄8 1725 3.0 56HZ 7 ⁄8 1745 5.0 184T 1 1 ⁄8 1755 7.5 S213T 13⁄8 1755 10.0 D215T 13⁄8 1425 2.4 56Y 5 ⁄8 1425 2.4 56Y 5⁄8 1425 2.9 56Y 7 ⁄8 1425 2.9 56Y 7 ⁄8 1425 2.9 56Y 7 ⁄8 1425 5.0 184T 1 1 ⁄8 1425 7.5 S213T 13⁄8 1425 10.0 S215T 13⁄8 NEMA — National Electrical Manufacturers Association Table 8B — Fan Motor Data, Alternate Motor — English UNIT 40RM 007 208/230-1-60 Speed (rpm) 1725 Hp 2.4 Frame (NEMA) 56Y 5⁄8 Shaft Dia (in.) 208/230-3-60 and 460-3-60 Speed (rpm) 1725 Hp 2.9 Frame (NEMA) 56Y 7⁄8 Shaft Dia (in.) 575-3-60 Speed (rpm) 1725 Hp 2.0 Frame (NEMA) 56HZ 7⁄8 Shaft Dia (in.) 230-3-50 and 400-3-50 Speed (rpm) — Hp — Frame (NEMA) — Shaft Dia (in.) — 40RM 40RMQ 40RMS 008 40RMS 010 40RM 40RMQ 40RMS 012 40RM 40RMS 014 40RM 40RMQ 40RMS 016 40RM 40RMS 024 40RM 40RMS 028 — — — — — — — — — — — — — — — — — — — — — — — — — — — — 1725 2.9 56Y 7 ⁄8 1725 2.9 56Y 7⁄8 1725 3.7 Y56Y 7 ⁄8 1725 3.7 Y56Y 7⁄8 1725 5.0 S184T 11⁄8 1745 7.5 S213T 13⁄8 1745 10.0 S215T 13⁄8 1725 3.0 56HZ 7 ⁄8 1725 3.0 56HZ 7⁄8 1725 3.0 56HZ 7 ⁄8 1745 5.0 184T 1 1 ⁄8 1745 5.0 184T 11⁄8 1755 7.5 S213T 13⁄8 1750 10.0 D215T 13⁄8 1425 2.9 56Y 7 ⁄8 1425 2.9 56Y 7⁄8 1425 5.0 S184T 7 ⁄8 1425 5.0 S184T 1 1 ⁄8 1425 5.0 S184T 11⁄8 1425 7.5 S213T 13⁄8 1425 10.0 S215T 13⁄8 NEMA — National Electrical Manufacturers Association 26 Table 8C — Fan Motor Data, Standard Motor — SI UNIT 40RM 007 208/230-1-60 Speed (r/s) 28.75 Shaft kW 0.97 Frame (NEMA) 56Y Shaft Dia (mm) 15.9 208/230-3-60 and 460-3-60 Speed (r/s) 28.75 Shaft kW 1.79 Frame (NEMA) 56Y Shaft Dia (mm) 15.9 575-3-60 Speed (r/s) 28.75 Shaft kW 0.746 Frame (NEMA) 56 Shaft Dia (mm) 15.9 230-3-50 and 400-3-50 Speed (r/s) 23.75 Shaft kW 1.79 Frame (NEMA) 56Y Shaft Dia (mm) 15.9 40RM 40RMQ 40RMS 008 40RMS 010 40RM 40RMQ 40RMS 012 40RM 40RMS 014 40RM 40RMQ 40RMS 016 40RM 40RMS 024 40RM 40RMS 028 40RM 40RMS 034 28.75 1.79 56Y 15.9 28.75 1.79 56Y 15.9 — — — — — — — — — — — — — — — — — — — — — — — — 28.75 1.79 56Y 15.9 28.75 1.79 56Y 15.9 28.75 1.79 56Y 15.9 28.75 2.16 56Y 22.2 28.75 2.76 56Y 22.2 29.08 3.73 S184T 28.6 29.08 5.60 S213T 34.9 29.08 7.46 S215T 34.9 28.75 1.49 56HZ 22.2 28.75 1.49 56HZ 22.2 28.75 1.49 56HZ 22.2 28.75 2.24 56HZ 22.2 28.75 2.24 56HZ 22.2 29.08 3.73 184T 28.6 29.25 5.60 S213T 34.9 29.25 7.46 S215T 34.9 23.75 1.79 56Y 15.9 23.75 1.79 56Y 15.9 23.75 2.16 56Y 22.2 23.75 2.16 56Y 22.2 23.75 2.16 56Y 22.2 23.75 3.73 184T 28.6 23.75 5.60 S213T 34.9 23.75 7.46 S215T 34.9 NEMA — National Electrical Manufacturers Association Table 8D — Fan Motor Data, Alternate Motor — SI UNIT 40RM 007 208/230-1-60 Speed (r/s) 28.75 Shaft kW 1.79 Frame (NEMA) 56Y Shaft Dia (mm) 15.9 208/230-3-60 and 460-3-60 Speed (r/s) 28.75 Shaft kW 2.16 Frame (NEMA) 56Y Shaft Dia (mm) 22.2 575-3-60 Speed (r/s) 28.75 Shaft kW 1.49 Frame (NEMA) 56HZ Shaft Dia (mm) 22.2 230-3-50 and 400-3-50 Speed (r/s) — Shaft kW — Frame (NEMA) — Shaft Dia (mm) — 40RM 40RMQ 40RMS 008 40RMS 010 40RM 40RMQ 40RMS 012 40RM 40RMS 014 40RM 40RMQ 40RMS 016 40RM 40RMS 024 40RM 40RMS 028 — — — — — — — — — — — — — — — — — — — — — — — — — — — — 28.75 2.16 56Y 22.2 28.75 2.16 56Y 22.2 28.75 2.76 Y56Y 22.2 28.75 2.76 Y56Y 22.2 29.08 3.73 S184T 28.6 29.08 5.60 S213T 34.9 29.17 7.46 S215T 34.9 28.75 2.24 56HZ 22.2 28.75 2.24 56HZ 22.2 28.75 2.24 56HZ 22.2 29.08 3.73 184T 28.6 29.08 3.73 184T 28.6 29.25 5.60 S213T 34.9 29.17 7.46 D215T 34.9 23.75 2.16 56Y 22.2 23.75 2.16 56Y 22.2 23.75 3.73 S184T 22.2 23.75 3.73 S184T 28.6 23.75 3.73 S184T 28.6 23.75 5.60 S213T 34.9 23.75 7.46 S215T 34.9 NEMA — National Electrical Manufacturers Association 27 Table 9A — Standard Drive Data, 60 Hz — English UNIT MOTOR DRIVE Motor Pulley Pitch Diameter (in.)

Filters — Filters can be removed and installed from either side of the unit. Install new filters in units that have one fan as follows: 1. Remove the side access panel (retain screws). 2. Remove the filter retainer clip. 3. Remove old filters by tilting them and lifting them out of the filter track. See Fig. 12 and 22. 4. Reverse the procedure to install new filters. LEGEND ESP — External Static Pressure NOTES: 1. Maximum allowable fan speed is 18.3 r/s for unit sizes 028 and 034; 20 r/s for all other sizes. 2. Fan performance is based on deductions for wet coil, clean 51-mm filters, and unit casing. See right for factory-supplied filter pressure drop. 3. Refer to fan motor and drive tables for additional data. To install new filters in larger units that have 2 fans, follow the preceding steps, but use the factory-supplied filter hook to slide filters within reach for removal. The filter hook is shipped inside the unit in the baserail.
