fRecommended field-supplied filters are 1-in thick
Step 2 — Mount Heat Pump Package
ON THE GROUND; MOUNT HEAT PUMP ON
AN ELEVATED FRAME POSITIONED ON A
LEVEL CONCRETE PAD See Pig. 2 for pad
dimensions. Ensure pad does not obstruct coil slots
in unit basepan. (Slots drain water during heating
and defrost cycles. See Fig. 2 for drain slot loca­
tions.) Construct pad a minimum of 6 in. thick to
provide clearance under basepan coil slots for
drainage and ice buildup. In areas where prolonged
subfreezing
temperatures or snowfall occur,
increase clearance to 12 to 18 inches by constructing
an angle-iron frame to support unit 12 to 18 in. off
concrete base. Design cross angle of frame so as to
not obstruct basepan coil slots. See Fig. 3 for recom­
mended frame construction. Alternate construction
should follow dimensions. Extend a 24-in. gravel
apron around pad for condensate and defrost water
drainage field.
ON THE ROOF: MOUNT UNIT ON A LEVEL
PLATFORM OR FRAME — Elevate unit for
proper clearance as described under ground installa­
tion above. Design roof and plan water runoff so as
to prevent unit and its duct flashing from sitting in
water, in accordance with all applicable codes.
Step 3 — Make Ductwork Connections
CONNECT RETURN AND SUPPLY AIR
DUCTWORK — Connect ductwork to unit supply
and return air duct connections. Refer to Fig. 1 and
Table 1 for unit supply and return air connection
sizes and locations.
