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.
All condensate hose extensions should be
in accordance with local building codes.
Remember water only flows downhill to
ensure positive draining from the unit.
Check using water for a positive flow of
condensate.
The basic system installation is now com-
plete. The unit is now ready for start up.
SYSTEM START UP
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 condenser is charged with enough
R410A refrigerant for 16 feet of interconnect.
For longer line set lengths additional charge
must be added in per the following table.
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.
