Note:
Connect the connection pipe to indoor unit at first and then
to outdoor unit. Handle piping bending with care. Do not
damage the connection pipe. Ensure that the joint nut is
tightened firmly, otherwise, it may cause leakage.
Installation of outdoor unit
Electric 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. Wiring should fit
that of indoor unit.
3 Fix the power connection cord with wire clamps and then
connect the corresponding connector.
4 Confirm if the wire has been fixed properly.
5 Reinstall the handle.

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 the handle of Lo manifold valve.
4 Open the vacuum pump for vacuumisation. 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 vacuuming for more than 15mins and make sure the
reading of multi-meter is -1.0 10
5
pa (-76cmHg).
6 Fully open high/low pressure valves.
7 Remove charging hose from charging end of low
pressure valve.
8 Tighten lid of low pressure valve. (As shown in below)

Outdoor condensate drainage (only for heat pump unit)
During heating operation, the condensate and defrosting
water should be drained out reliably through the drain hose.
Install the outdoor drain connector in a 25mm 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 25mm must be plugged.
Whether to plug other holes will be determined by the
installer according to actual conditions.
