INSTALLATION MANUAL

7.4 Installing Outdoor Unit

Electric wiring

Disassemble the cable cross plate sub-assy on the outdoor unit right side plate.

Take off wire clamp. Connect and fix power connect

cord (for cooling and heating unit,connect and fix power connect cord and signal control wire)to terminal of line

bank. Wiring should fit that of indoor unit.

Fix the power connection cable with wire clamp, (for cooling and heating unit, use the wire clamp

to fix the power connection cable and the signal control wire), then connect the corresponding connector.

Ensure wire has been fixed well. Install the cable cross plate sub-assy.

NOTE:

Wrong wiring may cause spare parts malfunction.

After the cable fixed, make sure there should be a free space between the connection and connection and fixing place on the lead wire.

Air purging and leakage test

1.Connect charging hose of manifold valve to charge end of low pressure valve (both high/low pressure valves must be tightly shut).

2.Connect joint of charging hose to vacuum pump.

3. Fully open handle handle of Lo manifold valve.

4.Open the vacuum pump to evacuate. At the beginning, slightly loosen joint nut of low pressure valve to check if there is air coming inside. (If noise of vacuum pump has been changed, the reading of multimeter is 0) Then tighten the nut.

5.Keep evacuating for more than 15mins and make

sure the reading of multi-meter is 5

6.Fully open high/low pressure valves.

7.Remove charging hose from charging end of low pressure valve.

8.Tighten bonnet of low-pressure valve. (As shown in Fig.10)

Condensate drainage of outdoor unit (not for cooling only)

The condensate and defrosting water formd during heating in the outdoor unit can be properly discharged by drainage pipe .

Installation method:set the drain connection inØ 25 hole of the chassis has been installed and then connect drainage pipe with drain nozzle,so that condensate and defrosting water can be properly discharged
