Safety
• The maintenance cover plate of the indoor or outdoor machine is forbidden when the main circuit power supply is not cut o󰀨.
• The leakage of refrigerant can cause the air to be thin and di󰀩cult to breathe. In case of refrigerant leakage, close the main valve, extinguish any ame and contact the local distributor immediately.
• Please use ELB (leakage protector). If not used, an electric shock or re may occur when an accident occurs.
• The installation and Service Engineer shall ensure that the refrigerant leaks comply with local laws and regulations.
CAUTION
• Execute earthing for the unit. But the earthing wire can not be connected to the gas pipe, water pipe, lightening rod or the telephone earthing wire. Improper earthing will cause electric shock.
• Don't install the unit at the place where leaks the ammable gas. Or it will cause re.
• Execute the water drainage pipe according to the manual, improper installation will cause water leakage to wet the family things.
• The outdoor fan can not face to the ower or the other vegetable, or the blowing gas will make the ower dried up.
• Please ensure the maintenance room, if not, it will cause the maintenance person damaged.
• When installing the unit on the roof or the other high place, to prevent the person falling down, please set the xed ladder and the railing at the passage.
• Use the two-end spanner, and fasten the nut at proper torque. Don't fasten the nut excessively against the ared setion broken. Or it will cause refrigerant leakage and lack of oxygen.
• Take measures for heat insulation to the refrigerant pipe, or there will be water leakage or dew drop to wet the family things.
• After nishing the refrigerant pipe, make leakage test by charging the nitrogen. In case the refrigerant leaks in a small room and exceeds the limited concentration, it will cause lack of oxygen.
• Don't use the other refrigerant except for R410A. The R410A pressure is 1.6 times higher than R22 pressure. The refrigerant R410A tank is marked with pink sign.
• Against charging di󰀨erent refrigerant, we changed the stop valve diameter of the R410A unit. To enhance the compression consistance, we also changed the ared pipe dimension. Prepare the R410A specially tools according to the below table.

(5) Refrigerant pipe connection
Pipe connection method:
• To ensure the e󰀩ciency, the pipe should be as short as possible.
• Daub the refrigerant oil on the connector and the are nut.
• When bending the pipe, the bending semi-diameter should be as large as possible against the pipe being broken or
bent.
• When connecting the pipe, aim at the center to thread the nut by hand and tighten it with the double spanners.
• Don't let the impurity such as sand, water etc into the pipe.
When fastening and loosing the nut, operate with double spanners, because only one spanner cannot execute rmly.
Spanner
Connector
Nut
Spanner
If threading the nut as not aiming at the center, the screw thread will be damaged, further it will cause leakage.
Cautions in piping installation:
• When welding the connector with hard solder, charge nitrogen into the pipe against oxidation. Or the oxygen lm in the
pipe will clog the capillary and the expansion valve, even caue the deathy accident.
• The refrigerant pipe should be clean. If the water and the other impurity enter the pipe, charge the nitrogen to clean the
pipe. The nitrogen should ow under the pressure of about 0.5Mpa and when charging the nitrogen, stop up the end of the pipe by hand to enhance the pressure in the pipe, then loose the hand (meanwhile stop up the other end).
• The piping installation should be executed after the stop valves are closed.
• Before welding the valve and the pipes, use the wet cloth to cool down the valve and the pipes.
• When the connection pipe and the branch pipe need to be cut down, please use the special shears and cannot use the
saw.
Pipe material and specs selection
1. Please select the refrigerant pipe of the below material. Material: the phosphoric oxidize seamless copper pipe, model: C1220T-1/2H (diameter is over 19.05); C1220T-0 (diameter is below 15.88).
2. Thickness and specs: Conrm the pipe thickness and specs according to the pipe selection method(the unit is with R410A, if the pipe over
19.05 is 0-type, the pressure preservation will be bad, thus it must be 1/2H type and over the min. thickness.
3. The branch pipe must be from Haier.
4. When installing the stop valve, refer to the relative operation instruction.
5. The pipe installation should be in the allowable range.
6. The installation of branch pipe and gather pipe should be performed according to the relative manual.

Trial operation and the performance

Conrm the type of outdoor machine and the number of inside machine
• After installation, please conrm that the outdoor computer board BM1_1 is in the 0 state, and then to the unit power, observe the digital display. If the number of the indoor machine and the outdoor machine type, the power supply voltage is correct, then the BM1_1 dial to 1 of the state, if it is not correct, please check the dial machine communication code and models, do not force the BM1_1 dial to 1 of the state, it may cause failure of the system.
5-minute delay function
• If starting up the unit after being powered o󰀨, the compressor will run about 5 minutes later against being damaged.
Cooling/heating operation
• Indoor units can be controlled individually, but cannot run in cool and heat mode at the same time. If the cool mode and the heat mode are existing simultaneously, the unit set latter will be standby, and the unit set earlier will run normally. If the A/C manager sets the unit at cooling or heating mode xedly, the unit can not run at the other modes.
Heating mode characteristic
• In operation if outdoor temp. arises, indoor fan motor will turn to low speed or stop.
Defrosting in heating mode
• In heating mode, outdoor defrosting will a󰀨ect the heating e󰀩ciency. The unit will defrost for about 2~10 minutes automatically, at this time, the condensate will ow from outdoor, also in defrosting, the vapour will appear at outdoor, which is normal. Indoor motor will run at low speed or stop, and outdoor motor will stop.
The unit operation condition
• To use the unit properly, please operate the unit under the allowed condition range. If operating beyond the range, the protection device will act.
• The relative humidity should be lower than 80%. If the unit runs at the humidity over 80% for a long period, the dew on the unit will drop down and the vapour will be blowed from air outlet.
Protection device (such as high pressure switch)
• High pressure switch is the device which can stop the unit automatically when the unit runs abnormally. When the high pressure switch acts, the cooling/heating mode will stop but the running LED on wired controller will be light still. The wired controller will display failure code. When the following cases occur, the protection device will act: In cooling mode, air outlet and air inlet of outdoor are clogged. In heating mode, indoor lter is sticked with duct; indoor air outlet is clogged. When protection device acts, please cut o󰀨 the power source and re-start up after eliminating the trouble.
When power failure
• When power is failure in running, all the operations will stop.
• After being electried again, if with re-satrt up function, the unit can resume to the state before power o󰀨 automatically; if without re-satrt up function, the unit needs to be switched on again.
• When abnormal occurs in running because of the thunder, the lightning, the interference of car or radio, etc, please cut o󰀨 the power source, after eliminating the failure, press "ON/OFF" button to start up the unit.
Heating capacity
• The heating mode adopts the heat pump type that absorbs outdoor heat energy and releases into indoor. So if outdoor temperature goes down, the heating capacity will decrease.
System marks
• On the condition that multi Outdoor systems are installed, in order to conrm the relationship between outdoor and indoor, please make marks on outdoor electric control box cover to indicate the connected indoor unit. As the below gure:
Indoor model:
Room No. e.g. Indoor A, system 1, Floor 2 2F-1A

Trial operation and the performance
Trial operation
• Before trial operation: Before being electried, measure the resistor between power terminal block (live wire and neutral wire) and the earthed point with a multimeter, and check if it is over 1MΩ. If not, the unit can not operate. To protect compressor, electrify the outdoor unit for at least 12 hours before the unit runs.If the crankcase heater is not electried for 6 hours, the compressor will not work. Conrm the compressor bottom getting hot. Except for the condition that there is only one master unit connected (no slave unit), under the other conditions, open fully the outdoor operating valves (gas side, liquid side). If operating the unit without opening the valves, compressor failure will occur. Conrm all indoor units being electried. If not, water leakage will occur. Measure the system pressure with pressure gauge, at the same time, operate the unit.
• Trial operation In trial operation, refer to the information of performance section. When the unit can not start up at the room temperature, make trial operation for outdoor.
