S
Make a trap of at least 2 in. (51 mm) in depth to prevent
unpleasant odors from reaching the room.
S
Insulate condensate pipe with condensation proof materi-
al such as polyurethane, propylene, or neoprene of 3/16
in. to 3/8 in. thickness.
CAUTION
!
ELECTRICAL OPERATION HAZARD
Failure to follow this caution may result in personal injury.
The drain tube extension must be securely fastened to the
condensate drain. Failure to do so could result in condensate
water dripping onto the floor.
NOTE
: Should the installation require one, a condensate pump
may be ordered as a field--installed accessory. It is easier to install
pump before hanging the unit.

S
Remove the cover of the drain hose connection port.
S
Insert the flexible hose (field supplied, I.D.: 1”) to the
drain hose port. Securely fix it to the indoor unit with a
pipe clamp (field supplied).
S
Install the flexible hose onto the PVC water pipe with
PVC adhesive (see Fig. 20).
S
To ensure correct condensate water flow, the pipe should
have a gradient of 2% without obstruction (see Fig. 20).
DO NOT install the drainpipe to an upward position. It
may cause water to flow back to the unit.
S
Make a trap of at least 2 in. (51 mm) in depth to prevent
unpleasant odors from reaching the room.
S
Insulate condensate pipe with condensation proof materi-
al such as polyurethane, propylene, or neoprene of 3/16
in. to 3/8 in. thickness.
S
The drain line must not have a trap anywhere in its
length, must pitch downwards, and must be insulated up
to the outside wall (see Fig. 22).

INSTALL OUTDOOR UNIT
The outdoor units can be installed on the ground, on the roof, or
mounted on a wall.
NOTE
:
Install the unit so that the coil does not face into
prevailing winds. If this is not possible and constant winds
above 25 mph are expected, use accessory wind baffle. See the
installation instructions provided with accessory kit. Wind
baffles should also be used on all units with accessory low
ambient temperature control.
Mounting on Ground
1. Mount unit on a solid level concrete pad.
2. If a heat pump is being installed, use a field-- provided snow
stand or ice rack where prolonged subfreezing temperatures
or heavy snow occurs.
3. Position unit so water or ice from roof does not fall directly
onto unit.
4. On cooling only units, an accessory stacking kit can be used
when units are to be stacked. See installation instructions
provided with the accessory kit.
Mounting on Roof
IMPORTANT: Mount unit on a level platform or frame at
least 6 in. (152.4 mm) above roof surface. Isolate unit and
tubing from structure.
