The heat pump or condensing unit should be hoisted with 2 lifting
slings. Attach the slings to rigging shackles that have been
hooked through holes in the lifting brackets.
Place 2 spreaders on top of the heat pump or condensing unit to
protect it from damage from the pressure exerted by the slings.
Make sure that all equipment is rated to handle at least 750 lbs
and that the slings will not allow the heat pump or condensing
unit to shift. See "Typical Sling Configuration."

Convert to Downflow

This heat pump or condensing unit is factory-built for horizontal
airflow applications and may also be field-converted for
downflow use.
To convert to downflow use:
1. Remove the filter access panel.
2. Remove the two downflow duct cover plates (one screw and
tab for each) found in the return and supply air
compartments.
3. Using eight #10 x ³⁄₄" screws (field supplied), install the
previously removed duct covers on the horizontal return and
supply air openings. Use the pilot holes provided.
4. Reinstall the filter access panel.

Connect Condensate Drain

The condensate drain outlet is a ³⁄₄" threaded PVC fitting located
at the bottom on the side of the heat pump or condensing unit. A
³⁄₄" drain line with trap must be installed on all applications to
avoid accumulation of condensate under or around the heat
pump or condensing unit.
Install Condensate Trap
1. Construct the condensate trap from PVC tubing as shown in
"Condensate Trap Construction."
NOTES:
The condensate trap allows a standing column of water of
at least 2" (50 mm).
The top of the drain trap inlet must be at least least 1"
(25 mm) above the top of the drain trap outlet.
The trap should be installed as close to the heat pump or
condensing unit as possible, while still providing proper
drainage.
For service access, do not block heat exchanger access
panel or the filter access panel with the drain line.
2. Thread the drain assembly into the ³⁄₄" PVC fitting.
NOTE: Do not glue the threaded fitting so it can be removed
during servicing of unit.
3. Run the drain line to an open drain or other suitable disposal
point.
