Be sure that no dust is mixed in piping. Bend piping with as wide angle as possible. Keep insulating both gas and liquid piping. Check flare-connected area for gas leakage. Piping connection Connecting method (indoor unit) Apply refrigerant oil at half union as large and flare nut. To bend a pipe, give the roundness as possible not to crush the pipe. When connecting pipe, hold the pipe centre to centre then screw nut on by hand, refer to Fig. Be careful not to let foreign matters, such as sands enter the pipe. Forced fastening without centering may damage the threads and cause a gas leakage.

The air tightness test adopts nitrogen tank to give pressure according to the pipe connection mode as the following figure shown. The gas and liquid valve are all in close state. In order to prevent the nitrogen entering the circulation system of outdoor unit, tighten the valve rod before giving pressure (both gas and liquid valve rods).

Second step: 1.5Mpa (15kg/cm2g) pressurize over 3 minutes. Large leakage will be found. Third step: 3.0 MPa (30kg/cm2g) pressurize about 24 hours. Little leakage will be found. Check if the pressure drops If the pressure does not drop, the unit is passed If the pressure drops, please check the leaking point. After pressurizing for 24 hours, each 1 C difference of ambient temperature will result in 0.01MPa(0.1kg/cm2g) pressure change. It shall be corrected during test. Checking the leaking point From the first to third steps, if the pressure drops, check the leakage in each joint by the sense of hearing, feeling or soap water, etc. to find the leaking point. After confirming the leaking point, welding it again or tighten the nut tightly again. Piping and indoor unit vacuumizing Use vacuum pump to perform vacuumizing. It is strictly forbidden to use the refrigerant to remove the air inside the system. After air tightness test and discharging all the nitrogen, connect the vacuum pump as the following figure shown. Indoor Outdoor Completely tightened Low pressure gauge 3-way valve totally closed (Gas side) VLVH Flare part High pressure gauge Meter separator Discharging valve P Completely tightened Indoor units Flare part Vacuum pump Outdoor units 2-way valve totally closed (Liquid side) It shall use the vacuum pump of (lower than -755mmHg)high vacuum degree and large air discharging (over 40l/min). The vacuumizing time depends on the length of the connecting pipe, generally is 1~2 hours. When vacuumizing, it shall be confirmed both gas and liquid side valves are closed. If after 2 hours vacuumizing, it cannot reach the vacuum degree below -755mmHg, it can be vacuumized for other 1 hour. 32 If after 3 hours vacuumizing, it still cannot reach the vacuum degree below -755mmHg, check if there is any leaking point and repair the them. Commercial Air Conditioner Model: HBU-18/28/42HF03 HBU-28CF03 HDU-18/28CF03 HDU-18/28HF03 HDU-42HF03/H If after over 2 hours vacuumizing, the vacuum degree is below -755mmHg, close the VL and VH on the meter separator and stop vacuumizing. 1 hour later to confirm if the vacuum degree changes. If changes, it indicates there is leaking point in the system. Check the leaking point and repair. After finishing the above vacuumizing, change the vacuum pump into refrigerant pump to charge the refrigerant. Charging amount of refrigerant When the total length (L) of the two indoor units' connecting pipe is less than 5m, it is unnecessary to charge additional refrigerant. If the connecting pipe (L) exceeds 5m, it shall charge Mg additional refrigerant per meter. That is: Refrigerant charging amount = (L-5) x M (g) For the unit with liquid pipe 6.35mm, M=30 For the unit with liquid pipe 9.52mm, M=65 Only in COOLING operation can charge the additional refrigerant. When charging, the refrigerant shall be charged from the charging nozzle of low pressure vavle. Be carefull when charging refrigerant, do not let the air mix into the system,and must charge the additional refrigerant in liquid condition.

Hanging bolt M10 nut Main unit M10 washer M10 spring washer Note When the dimensions of main unit and ceiling holes does not match, it can be adjusted with the slot holes of hanging bracket. 48 Commercial Air Conditioner Adjusting to the levelness (a) Adjust the out-of levelness using a level or by the following method. Make adjustment so that the relation between the lower surface of the unit proper and water level in the hose becomes as given below.

(b) Unless the adjustment to the levelness is made properly, malfunctioning or failure of the float switch may occur. Tap selection on blower unit (When the high performance filter is used.) Taps of blower unit are set at the standard selection at the shipping from factory. Where the static pressure is raised by employing such option as the high performance filter, etc., change the connection of connectors provided at the flank of control box as shown below. Red Yellow Red Black White Red Yellow Blue Blue Red Moter side Red Connector white Yellow Blue Moter side Blue High speed tap White White White White Connector white Control box side Standard tap (at shipping) (2) Drain Piping (a) Drain piping should always be in a downhill grade (1/50~1/100) and avoid riding across an elevation or making traps. Good piping Suspension 1.5m ~ 2m bolts Inproper piping Avoid riding across an elevation Air vent Keep free from traps A downhill grade Heat insulation of 1/100 or more Do not pipe under water (b) When connecting the drain pipe to unit, pay suffcient attention not to apply excess force to the piping on the unit side. Also, fix the piping at a point as close as possible to the unit. Stage difference Drain hose Drain socket part Drain socket (c) For drain pipe, use hard PVC general purpose pipe VP-25(I.D.1") which can be purchased locally. When connecting, insert a PVC pipe end securely into the drain socket before tightening securely using the attached drain hose and clamp. Adhesive must not be used connection of the drain socket and drain hose (accessory). 49 Main unit VP 25 joint Pipe cover(large) (field purchased) [for insulation] (accessory) Drain hose Clamp (accessory) (accessory) Adhesion Pipe cover(small) [for insulation] (accessory) VP 25 (field purchased) Pipe cover [for insulation] (field purchased) Commercial Air Conditioner Model: HBU-18/28/42HF03 HBU-28CF03 HDU-18/28CF03 HDU-18/28HF03 HDU-42HF03/H Secure the elevation as high as possible (approx. 100 mm) (d) When constructing drain piping for several units, position the A downhill grade of 1/100 or more 290~325mm 600 Drain hose (Maximum local drain up dimension) common pipe about 100 mm below the drain outlet of each unit as shown in the sketch. Use VP-30(11/4") or thicker pipe for this purpose. (e) Be sure to provide heat insulation to hard PVC pipes of indoor placement. (f) Do not ever provide an air vent. (g) The height of the drain head can be elevated up to a point 500 mm above the ceiling, and when an obstacle exists in the ceiling space, elevate the piping to avoid the obstacle using an elbow or corresponding gadget. When doing this, if the stretch for the needed height is higher than 500 mm, the backflow quantity of drain at the event of interruption of the operation gets too much and it may cause overflow at the drain pan. Therefore, make the height of the drain pipe within the distance given in the sketch below. (h) Avoid positioning the drain piping outlet at a place where generation of odor may be stimulated. Do not lead the drain piping direct into a sewer from where sulfur gas may generate. VP 30 Right overhead Joint for VP 25 (Local procurement) Drainage Test 1 2 3 4 Conduct a drainage test after completion of the electrical work. During the trial, make sure that drain flows properly through the piping and that no water leaks from connections. In case of a new building, conduct the test before it is furnished with the ceiling. Be sure to conduct this test even when the unit is installed in the heating season. Procedures 1 2 Supply about 1000 cc of water to the unit through the air outlet using a feed water pump. Check the drain while cooling operation. Pour water into a convex joint. Insert water supply hose for 20 mm ~ 30 mm to supply water. (Insert hose facing toward bottom.) Attached drain hose clamp Remove grommet. Make sure to install it back after test. Main unit Drain piping Drain situation can be checked with transparent socket 50 (In the electrical work has not been completed, connect a convex joint in the drain pipe connection to provide a water inlet.

In the following selections, Tr means room temperature and Ts means setting temperature. Select running mode according to the following conditions at the first time to enter Auto mode: Tr Ts-3 to select cooling mode (with setting temperature being Ts +3) Tr<Ts-3 to select heating mode (with setting temperature being Ts) After the system entering auto run mode, the running mode can convert automatically according to variation of room temperature between cooling, blowing and heating in the way shown as the chart below: P R R 5 Cooling Blowing H U X W D U H S P H W J Q L O O D I Ts-3 Ts-3 Room temperature rising Cooling Ts+3 Heating b. Single Cooling Type Select running mode according to the following conditions at the first time to enter Auto mode: to select cooling mode Tr Ts + 3 Tr < Ts + 3 to select blowing mode After the system entering auto run, the running mode can convert automatically according to variation of room temperature between cooling and blowing functions in the way shown as the chart below: P R R 5 H U X W D U H S P H W J Q L O O D I 79 Ts+3 Cooling Blowing Blowing Room temperature rising Ts-3 Cooling Commercial Air Conditioner Model: HBU-18/28/42HF03 HBU-28CF03 HDU-18/28CF03 HDU-18/28HF03 HDU-42HF03/H (2) Auto Selection of Wind Speed In the following, Tr means room temperature while Ts means setting temperature. a. During cooling program conversion of wind speed from the low to high won’t work until the present speed has continued for 3 minutes while conversion from the high to low needs no time delay. The chart below is the sketch map of conversion: Temperature falling High speed Ts High speed Ts 2 3 Medium speed 1 Low peed Ts Low speed Temperature rising Ts Medium speed b. During heating program applicable for cooling-heating type , conversion of wind speed from the low to high won’t work until the present speed has continued for 3 minutes while conversion from the high to low needs no time delay. The hart below is the sketch map of conversion: Temperature falling Low speed Low speed Ts Medium speed 1 Ts High speed 3 High speed 2 Temperature rising Medium speed Ts Ts (3) Dehumidifying program In the following, Tr means room temperature while Ts means setting temperature. a. After the system entering dehumidifying program, the compressor, outdoor and indoor blowing fans run according to the following rules: (1) Tr > Ts + 2 , the compressor and outdoor blowing fan run continuously while indoor 80 Commercial Air Conditioner Model: HBU-18/28/42HF03 HBU-28CF03 HDU-18/28CF03 HDU-18/28HF03 HDU-42HF03/H blowing fan runs at setting wind speed. This working area is defined as area A. (2) Ts Tr Ts + 2 , the compressor and outdoor blowing fan run for 10 minutes then pause for 6 minutes, while indoor blowing fan runs at low wind speed. This working area is defined as area B. (3) Tr < Ts, the compressor and outdoor blowing fan stop working while outdoor blowing fan runs at low wind speed. This working area is defined as area C. a. After dehumidifying program starting, the system converts between A, B and C areas according to variations of room temperature with running mode being shown as the chart below: Room temperature falling Area A Area A Ts Ts 1 Area B 1 Area C Ts Area C Room temperature rising Area B Ts 3 (4) Cutoff protection against overload and overheat During heating program, if the indoor blowing fan has been started and the compressor has been running more than 2 minutes, and the temperature of indoor coil pipe (Ticp) > 64 , the outdoor blowing fan will stops running; If Ticp 50 and the outdoor blowing fan has kept stop state for 45 seconds, then it will restore rotation; If Ticp > 67 and such temperature has last for 10 seconds, the compressor will stop running and indoor blowing fan run according to conditions as it reaches setting temperature. When Ticp < 58 , and the compressor has kept stop state over 3 minutes, then the compressor and outdoor blowing fan will restore normal running. Cutoff protection for heating current After 60 seconds from the compressor being started, if CT current exceeds I1 (9.2A) and such case has kept 5 seconds, the outdoor blowing fan will stop. If 45 seconds has passed after the outdoor blowing stops and the current of the compressor is less than I2 (7.5A), the blowing fan will restore running. If CT current exceeds I3 (14.3A) and such case lasts for 3 seconds, the compressor and outdoor blowing fan will stop. The compressor will not restore running until 3 minutes passes with CT current less than 12A. (5) Cool wind prevention during heating program At the first time entering heating program or after ending the latest frost removal, if the temperature of indoor coil pipe (Ticp) < 28 , the indoor blowing fan will stop running; If 28 Ticp < 38 , the indoor blowing fan will run at low speed; If Ticp > 38 or the compressor has been running for more than 4 minutes, the indoor blowing fan will run at 81 Commercial Air Conditioner Model: HBU-18/28/42HF03 HBU-28CF03 HDU-18/28CF03 HDU-18/28HF03 HDU-42HF03/H setting wind speed. (6) Afterheat blowing during heating program During heating program, the compressor will stop running (except overheat protection or frost removal) while the indoor blowing fan will firstly run for 50 seconds at low speed then stop. (7) Frost removal control (applicable for cooling-heating type) Starting conditions for frost removal: A The indoor unit is in overload protection and outdoor blowing fan stops. The outdoor blowing fan does not enter overheat mode in 10 minutes after it is restarted, the compressor has run over 45 minutes totally while 20 minutes continuously, and the temperature of indoor coil pipe is lower than 43 ; B After the compressor continuously running for 20 minutes, the temperature of indoor coil pipe falls 1 every 6 minutes and such case continuously appears three times, and the temperature of indoor coil pipe is less than 40 , and 5 minutes have passed after the compressor is restarted; C The compressor has run totally over 3 hours while 20 minutes continuously, and the temperature of indoor coil pipe is less than 40 ; D The difference between room temperature and the one of indoor coil pipe is less than 16 and the compressor has totally run over 45 minutes while 20 minutes continuously; Frost removal will start if any one of the above conditions is satisfied. Ending conditions for frost removal: 1 Time of frost removal has exceeded 9 minutes; 2 CT current exceeds I4(8.2A) Actions of each load after the frost removal starts: The compressor and outdoor blowing fan stop, and indoor blowing fan also stops. 55 seconds later the reversal valve is closed and next 5 seconds later the compressor is started. Actions of each load after the frost removal ends: The compressor stops running while outdoor blowing fan immediately runs at high speed, 55 seconds later the reversal valve is opened and next 5 seconds later the compressor restores running and indoor blowing fan runs as conditions for cool wind prevention. (8) Freeze protection After the compressor has run for 9 minutes, the system will check temperature of indoor coil pipe (Ticp). If Ticp is less than -1 , the compressor and outdoor blowing fan will stop. They will run again after the compressor stops if both the following conditions are satisfied: 1) 3 minutes have passed since compressor stops. 2) Ticp exceeds 7 . (9) 3 minutes protection for compressor After compressor stops, it cannot be started until 3 minutes later. During the machine’s running, if time after loosing power not exceeds 3 minutes, the compressor cannot be 82 Commercial Air Conditioner Model: HBU-18/28/42HF03 HBU-28CF03 HDU-18/28CF03 HDU-18/28HF03 HDU-42HF03/H restarted until 3 minutes later after it is reenergized. 10 Power breakdown memory If the machine suddenly loses power while running, or stops for maintenance or trouble shooting, it will restart running as the status when it stops after the power is restored. Note: 1. Function setting: Continuously press sleep button on the remote controller 10 times in 5 seconds and buzzer on control panel shall beep 4 times. 2. Memory content: Running mode, wind speed setting, temperature setting, swing status. 3. Cancel: Press sleep button on the remote controller 10 times and buzzer on control panel beeps 2 times. (11) Control of water pump a. In cooling (including automatic cooling mode) and dehumidifying modes, the water pump works if the compressor runs while stops 5 minutes later after the compressor stops. b. When water tank is fully filled, the float switch will be off. The water pump will start to work after a controller has detected this signal and it will continue working for 5 minutes after the float restores to normal state. c. If the full water signal is detected continuously over 5 minutes, the water pump indicator lamp will flash to alarm and compressor stops running. The water pump will run 5 minutes, then pause for 5 seconds before next 5 minutes’ running, ... until the float restores to normal state, after which the pump will run for 5 minutes then stop. (12) Monitoring of remote network Through preset interface, the air conditioner is connected to remote control detector (made by Haier) with 2-core cables for wire communication, to execute instructions sent from computer or centralized controller via remote control detector and meanwhile send present running status and trouble information of the machine to remote control detector. Connection between air conditioner and remote control detector: CN11 PC board AA+ Interface for remote control GHWHFWRU (13) Trial run Under shut-down state, hold pressing mandatory button. The buzzer will beep once, then twice after 5 seconds. Release the button to enter mandatory cooling mode, under which the indoor blowing fan runs at high speed with both the compressor and outdoor blowing fan working. Press the mandatory button again can end the mandatory mode. 83 Commercial Air Conditioner Model: HBU-18/28/42HF03 HBU-28CF03 HDU-18/28CF03 HDU-18/28HF03 HDU-42HF03/H 9.2 Defrost operation flow chart Come to defrost Compressor ON Open outdoor fun Compressor Condition off or 55s?
