Outdoor Unit - Installation
The outdoor unit needs to be installed by a
qualified heat pump split system installer/
refrigerant filler.
The best location for the outdoor unit is a place where:
•
It is not exposed to strong winds.
•
Airflow is good and dustless. At least 100mm space around the unit and
800mm space at the front.
•
Neighbours are not annoyed by the operation sound.
•
There is no risk of combustible gas leakage.
•
The condensation water can flow to a drain or will be absorbed by the
soil.
•
Flooding water cannot reach the base of the unit.
•
The outdoor unit should be fitted on feet on a level base or on a wall
bracket.
Please avoid locations where trouble is liable to occur:
•
Where flammable gas could leak.
•
Where there is much machine oil.
•
Salty places such as the seaside.
•
Where sulphide gas is generated.
The refrigerant R410a, pre-charged in the outdoor unit, is suitable for 5 meter
copper pipe. If the refrigerant pipes between the outdoor unit and the hot
water cylinder exceeds 5 meter, please add 10g R410a refrigerant per extra
meter of pipe. The maximum pipe length is 20 meters.
