2. Evaporator Unit Installation
1) The WM-252~652SFCV evaporator units should be installed for corner mount
with the supply air on the top and return air on the bottom.
2) Air supply shall be unobstructed minimum 12” for a direct blow installation;
leave 2” clearance for a deflector installation; air return shall be unobstructed
minimum 6”.
3) A grille can be used to cover the supply and return with 0~2” clearance; or 2-3
ft long duct can be added.
4) There is a gravity drain system used, so the unit shall be installed level or with
a slight slope downward the drain connection and the drain line shall be
installed slope down toward the drain. If rise-up is needed, a condensation
pump must be used.
3. Condensing Unit Installation
CAUTION:
Low ambient condition kit is required if the installation area will be below
50
°
F.
If the condensing unit is equipped with a low ambient condition kit,
do not turn on the compressor until the condensing unit has been powered
for minimum 12 hours.
