insulation. Do not insulate the liquid line
(small). Connect the outdoor unit according
to the instructions supplied with unit.
All horizontal piping runs must be level and
without dips to trap the oil.
pipinG do’s And don’ts
• Avoid piping on a rainy day.
• Use refrigerant grade copper tubing.
• Use a tubing bender and avoid unnec

the WLC/WLH piping connections can be
made by removing the left end cap and
bottom panel:
1. Remove the Philips-head
screws on bottom of
unit and lift bottom

When matching a the WLH24 with an 18,000
Btuh condenser circuit, the interconnecting
suction line needs to be 5/8” O.D. to match
the condenser service valve connection.
Therefore the 3/4” O.D. suction connection
of the WLH24 unit needs to be reduced to
5/8” at the WLH24 unit connection.
note:
The left end cap must
be removed prior to remov
-
ing the bottom.

ollow the
instructions on page 6 for
removing the end cap.
