System Start Up - Harbor Point HF-25GW Installation, Operation And Maintanance Manual

HARBOR POINT WALL SPLIT DUCTLESS SYSTEMS
12) Condensate Hose:
The unit is provided with approximately
18" of condensate hose connected. Hose
connection is sized to accept a 3/4" OD or
5/8" ID clear plastic hose to then extend to
building drain.
There is approximately 6' of additional
drain hose supplied with the (accessory)
line set.
With the evaporator and line set completely
evacuated the system can now be opened
to allow the refrigerant charge in the out-
door unit to be released into the line set.

The service valves require a 6mm and a
5mm Allen wrench respectively to undo
the valve stems. Remove the brass caps
from the service valves. Open the suc-
tion line valve first to prevent any pos-
sible oil logging of the capillary tube ex-
pansion device that can occur if the liquid
line valve is opened first with the rest of
the system in a deep vacuum. Then open
the "Liquid or Expanded Gas" line.
Unscrew both valve stems until they come
to a stop against the valve body, replace
the brass caps, then tighten the caps to
prevent leaks. Energize the breaker to al-
low system to be powered.
