WIRING & REFRIGERATION CYCLE DIAGRAMS, CAPACITY & PRESSURE CHARTS 2.1 Using CAL Model Air-Conditioner Cooling and Heating Capacity Curves Using the Cooling and Heating Capacity Curves. The Cooling and Heating Characteristics curves are mainly intented for use by air conditioning engineers as an aid in designing systems and in determining the capacity and number of units required at a given site. JULY 2000 5130-26135-86 The air conditioner capacities were determined in accordance with ISO 5151 standard operating conditions: Design parameters for a given site are often different than the standard conditions. Therefore, the design engineer should use the capacity charts which follow to calculate the capacity of the air conditioners under the intended working conditions, in order to optimize the selection of air conditioner units for use at a particular site. 1-72-1 CAL 2.1.1 Cooling and Heating Capacity Curves CAL 18 COOLING CAPACITY OUTDOOR TEMP.

Cassette Drain Pump Water Elevation Water elevation is 300 mm from false ceiling. The drain pipe cannot go higher than 300 mm because of the risk of water return from the pipe, when the unit stops (back flow) which could overflow the drain pan! 1-26 2-20 CAL Specification for the Water (Drain) Pump Control Water (Drain) Pump specifications Operation Life: Power Supply: Motor Type: Operating temperature: Operating humidity: Working fluid: Height difference: 15 years or 15,000 hours. 230V±10% - 1ph - 50Hz. Single phase 2 poles. 0 - 40∞C. Maximum 95%. Water condensation at 5∞C min. See the installation instructions of the unit. The Water Pump control is designed to control the water pump in the Cassette (CAL) type air conditioners. The Water Pump control operates the water pump with the TAC-404 Electronic Control Family. The Water Pump control is connected between the Main (TAC-444) and the Display Assy (TAC-460) in series. The main task of the water pump is to prevent a water flood whenever the air conditioner unit is in Cool mode or when switching to Off mode after Cool mode. The basic algorithm is that the water pump will work whenever the air conditioner is in cool mode and for the next 5 min. after the compressor is turned to Off in Cool Mode. Mechanical design: The water pump is designed to fit into the electric control box of the Cassette air conditioner. The PCB is attached to the electronic control box by four “snaps”. The “snaps” are placed on the four PCB corners (4mm hole). The Control is connected to the Main Board (TAC-444) and the Display Assy (TAC-460) via an RJ11 connector. The Control is connected to the Safety Level Switch (flood sensor) via two 6.3mm terminals. The Control is connected to the water pump via two 4.7mm terminals. JULY 2000 5130-26135-86 The control is connected to 230Vac power supply via a two terminal block. Electrical design: The pump control is powered by the TAC-444 main unit with a 10-18Vdc unregulated power supply. The pump control “reads” the communication line using the Current loop method. 1-27 2-21 CAL Inputs: Item 1. Description Operation Designation Main – Control Connects between the Main control unit communication (TAC-444) and the Pump Control.

Output: Item 1. Performance: The Pump Control uses the 20mA current loop method or the Open Collector method to monitor the communication between the TAC-444 – Main Unit & the TAC-460 Display. Normal operation: The Pump Control drives the Water Pump in the following conditions: ∑ When the A/C is in Cool mode (Reverse Valve off) and the compressor is activated. ∑ The Water Pump works continuously, as long as the compressor works, in cooling mode. ∑ The Water Pump will work for additional 5min. after any compressor stops (in Cool mode). ∑ Immediately when the safety level switch (flood sensor) indicates overflow. JULY 2000 5130-26135-86 When the floating sensor indicates overflow and turns the compressor off (temporary or total system halt) the Water Pump will work for additional 5min. ∑ After entering the Rest Loop (thermostat stop), the Water Pump will work for additional 5min. ∑ After a system operation halt (failure), the Water Pump will work for additional 5min. ∑ When switching from Cool to Heat mode, the Water Pump will work for additional 5min. ∑ In Heat mode, the water pump is always switched off. 1-28 2-22 CAL Recovery from power failures: The Pump-Control will activate the water pump for 5 min. each time after power recovery if the previous mode was Cool mode. Emergency operation: When the Pump Control detects a water overflow, by the safety level switch, it stops the communication between the TAC-444 - Main unit and the TAC-460 – Display. As mentioned above, the Pump-Control is connected in series between the TAC-444 and the TAC-460. The Pump-Control stops all commination simply by disconnecting the Display from the Main. This will cause the POWER indication light to flash (as in “normal” communication failure). During that time the Pump Control will activate the Water Pump as long as needed. The Pump Control will reactivate the communication when the overflow sensor is switched off. In case the overflow situation is repeated 3 times during a period of 30min., the Pump-Control will disable the operation of the A/C (total system halt), by disconnecting the communication, until a power reset. Otherwise, the Pump Control will begin the counting again. Recovery from the total system halt is done by sending Off to the system and then re-entry to On by mean of the 3-position slide switch (on the Display Assy). In case the safety level switch continuously signals fault (for a long time period), the Pump Control JULY 2000 5130-26135-86 will disconnect the communication, until the water level drops to normal. 1-29 2-23 CAL Water (Drain) Pump Troubleshooting Chart Warning: Always unplug the A/C before performing cleaning or maintenance activities. Symptom 1 Constant overflow. Probable Cause Corrective Action 1. Faulty Safety Level Switch. 1. Replace Safety Level Switch. 2. Stuck Safety Level Switch. 2. Remove obstruction or replace Safety Level Switch. 3. Safety Level Switch is disconnected. 3. Connect the Safety Level Switch. 4. Disconnected Water Pump communication cable. 4. Connect the Water Pump. 5. Totally clogged drainage. 5. Remove obstruction and clean the drain pan. Remove obstruction and clean the drain pan. Clean also the area near the water pump and the water pump filter. See all the above mentioned. 2 Cyclic overflow (three times during 30 min.) Partial blockages near the water pump that cause low handling capacity of the water pump. 3 Temporary overflow. Any reason from the above mentioned. This can also be a normal situation due to very high humidity levels that can cause high water flow. Note: flashing of the POWER indication light will indicate all types of overflow failures! Generally, water leaks can be caused due to ice formation at the bottom of the evaporator coil, due to lack of refrigerant (for example). When the evaporator enters the De-Ice procedure, the melted ice leaks from the drain pan. Important Note: remember that the condensed humidity must be pumped out of the drain pan after the unit is switched off. You must not turn the unit off by cutting out the main power supply. If the unit will be switched off via the power supply, the water pump will not operate for additional 5min. as required to remove the accumulated water, so a water leak can occur! JULY 2000 5130-26135-86 Air Distribution: Circulating the room air significantly reduces the temperature differences in the conditioned room. Circulation of the air is achieved by central air suction and the four directional louvers. The louvers are controlled (only) manually. If necessary, up to two louvers can be in a closed position, preventing air outlet to the specific direction that the closed louvers are facing. In Cassette models, there is high significance to the louver position in Cool and Heat modes. In Heat mode, it is strongly recommended that one or two louvers be closed to increase the air speed and the airflow downwards, especially in very high ceiling installations. Note: maximum of two louvers allowed to be closed for all units (see also: “Minimum clearances” at the Installation instructions). 1-30 2-24 CAL Conditioned Air Supply to an Adjacent Room: Option for delivering conditioned air to adjacent room via additional ducts is available in all models. One knockout exists in CALI-28-24 models or two knockouts in CALI-36-48 models. The knockouts are on one side only. Take this into consideration before positioning the indoor (evaporator) unit! Insulation of this duct is unnecessary only if it is routed via conditioned space (no humidity). Important Note: the maximal length of the duct should not exceed 3 meters. Beyond 3 meters, the airflow to the adjacent room will be insufficient. Also note: ∑ A return air path must be provided in case the conditioned air to the adjacent room option is being used. The return air path can be simply leaving the door open, installing a grill at the bottom of the door or an undercut at the bottom of the door. In the last option, consideration should be taken for the heat load in the space between the two conditioned rooms. ∑ Close the louver facing the adjacent room, to improve the airflow in the duct. ∑ Before connecting the ducts to the adjacent room (or rooms), verify that the unit capacity fits the heat load to be accepted from the adjacent room (or rooms). When the Cassette unit is installed over false ceiling, there is the possibility using one large unit (CALI 36 or CALI-48) for two rooms. In this case, locate the unit half in each room. It is possible only if the common wall thickness does not exceed 10 cm. In this case, no return air from the next room is needed. See also “Conditioned air supply to an adjacent room” in the Installation Procedure. Fresh Air Renewal: JULY 2000 5130-26135-86 Connection to a 4” fresh air inlet duct option is available in all Cassette models. The fresh air intake knockout is located near the conditioned air to the adjacent room duct knockout. For all models, option for only one duct is available. This duct does not require any insulation. Fresh air create positive pressure in the room, preventing external air entrance via any openings in the room and by that improves the air quality in the room. Important Note: in simple installations, the fresh air supply should not exceed 10% of the total airflow to prevent excessive heat load on the unit. Otherwise, a primary air treatment system with separate deflectors is recommended. Note: the fresh air knockout panel is located beside the blower intake. For fresh air ducts up to 2 meters, the air suction is performed by the unit’s blower suction power. Whenever the duct is longer than 2 meters, a supplementary fan motor should be added. Do not connect the supplementary fan motor to the Electronic Control supply. The supplementary fan motor should be powered only by a separate power supply in order to stop the fresh air supply in case of high outdoor temperature, and so on.
