Installation Basics
Unpacking the Unit
When the 2-piece heat pump reaches its destination it
should be unpacked to determine if any damage has occurred
during shipment. Any visible damage should be noted on the
carrier's freight bill and a suitable claim filed at once.
Indoor Unit Placement
For air to air units, to achieve the greatest efficiency, the
indoor unit should be centrally located in the home with respect
to the conditioned space. A heating system cannot be expected
to produce an even temperature throughout the house when it is
located at one end of the structure and the air is transmitted with
uninsulated metal ductwork.
If possible the front access panel and side access panel
opposite the air return should remain clear of obstruction for a
distance of two feet to facilitate servicing and general
maintenance. No access is required on the back side. Ensure
the unit is level to eliminate any possible condensate draining
issues.
Raising the indoor unit off the floor a few inches is
generally a good practice since this will prevent rusting of the
bottom panel of the unit and deaden vibrations. An anti-
vibration pad, available as an accessory, or a piece of 2”
styrofoam should be placed under the unit. Be careful not to run
piping in front of the filter rack access cover, since access is
required in order to change the air filter.
WARNING: Pool chemicals should be stored
in a different room from the PC unit to pre-
vent premature corrosion problems.
WARNING: Pool chemicals should be inject-
ed downstream of the PC unit.
