Install Outdoor Unit - CAC / BDP 40MKCF Installation Instructions Manual

Make a trap of at least 2 in. (51 mm) in depth to prevent
S
unpleasant odors from reaching the room.
Insulate condensate pipe with condensation proof materi-
S
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.

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
3. Position unit so water or ice from roof does not fall directly
Drain hose outlet
4. On cooling only units, an accessory stacking kit can be used
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.

Remove the cover of the drain hose connection port.
S
Insert the flexible hose (field supplied, I.D.: 1") to the
S
drain hose port. Securely fix it to the indoor unit with a
pipe clamp (field supplied).
Install the flexible hose onto the PVC water pipe with
S
PVC adhesive (see Fig. 20).
To ensure correct condensate water flow, the pipe should
S
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.
Make a trap of at least 2 in. (51 mm) in depth to prevent
S
unpleasant odors from reaching the room.
Insulate condensate pipe with condensation proof materi-
S
al such as polyurethane, propylene, or neoprene of 3/16
in. to 3/8 in. thickness.
The drain line must not have a trap anywhere in its
S
length, must pitch downwards, and must be insulated up
to the outside wall (see Fig. 22).
