6.10- INSTALLATION OF OUTDOOR UNIT
6.10.1- Electrical wiring
1. Remove the handle on the right side plate of outdoor unit;
2.
Take off wire cord anchorage. Connect and fix power
connection cord to the terminal board;
3. Fix the power connection cord with wire clamps and then
connect to the corresponding connector;
4. Confirm if the wire has been fixed properly.
NOTE:
Incorrect wiring may cause malfunction.
After the wire has been fixed, ensure there is free space between the
connection and fixing places on the lead wire.
6.10.2- Air purging and leakage test
1.
Connect charging hose of manifold valve to charge end of low
pressure valve (both high/low must be tightly shut);
2. Connect joint of charging hose to vacuum pump;
3. Fully open the handle of Lo manifold valve;
4. Open the vacuum pump for vacuumization. At the beginning,
slightly loosen joint nut of low pressure valve to check if there
is air coming inside. Then, tighten the nut;
5. Keep evacuating for more than 15 min. and make sure the
reading of multi-meter is -1,0x10
5
pa(-76 cmHg);
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 below)
6.10.3- Outdoor unit condensate drainage
During heating operation, the condensate and defrosting water should
be drained out reliably through the drain hose. Install the outdoor drain
connector in a
ɸ
,98in hole on the base plate and attach the drain hose
to the connector so that the waste water formed in the outdoor unit can
be drained out. The hole diameter 0,98 must be plugged. Whether to
plug other holes will be determined by the technician.
6.10.4- Check after installation and test operation
Items to be checked Possible malfunction
Has the unit been fixed firmly? The unit may drop, shake or emit
noise.
Have you done the refrigerant
leakage test? It may cause insufficient cooling
(heating).
Is thermal insulation sufficient? It may cause condensation.
Is water drainage satisfactory? It may cause water leakage
Is the voltage in accordance with
the rated voltage marked on the
nameplate? It may cause electric malfunction
or damage the unit.
Is the electric wiring or piping
connection installed correctly
and securely? It may cause electric malfunction
or damage parts.
Has the unit been securely
grounded? It may cause electrical leakage.
Is the inlet or outlet blocked? It may cause insufficient cooling
(heating).
Is the length of connection pipes
and refrigerant capacity been
recoreded? The refrigerant capacity is not
accurate.
6.10.5- Operation test
Before operation test:
1. Do not switch on power before installation is finished
completely;
2. Electric wiring must be connected correctly and securely;
3. Cut-off valves of the connection pipes should be opened;
4. All the impurities such as scraps and thrums must be cleared
from the unit.
Operation test method:
Switch on power and call for heating or cooling on thermostat to check
whether the operation is normal or not.
