RETURN AND DISCHARGE DUCT
FLANGES
Return and discharge opening duct flanges are
shipped unfolded. Flanges bend lines are
perforated allowing easy bending using standard
sheet metal pliers or channel locks. (Figure #3)

MOUNTING VERTICAL UNITS
Vertical units should be mounted level on a
vibration absorbing pad slightly larger than the
base to minimize vibration transmission to the
building structure. It is not necessary to anchor the
unit to the floor. (Figure #4).

MOUNTING HORIZONTAL UNITS
While horizontal units may be installed on any level
surface strong enough to hold their weight, they
are typically suspended above a ceiling by
threaded rods. The manufacturer recommends
these be attached to the unit corners by hanger
bracket kits. The rods must be securely anchored
to the ceiling. Refer to the hanging bracket
assembly and installation instructions for details.
Plumbing connected to the heat pump must not
come in direct contact with joists, trusses, walls,
etc. Some applications require an attic floor
installation of the horizontal unit. In this case the
unit should be set in a full size secondary drain pan
on top of a vibration absorbing mesh.
The Secondary drain pan prevents possible
condensate overflow or water leakage damage to
the ceiling.
The secondary drain pan is usually placed on a
plywood base isolated from the ceiling joists by
additional layers of vibration absorbing mesh. In
both cases, a 3/4”drain connected to this
secondary pan should be run to an eave at a
location that will be noticeable.

On VT Units Condensate Drain pan is internally
sloped. There is no internal P-Trap.
Horizontal units installed above the ceiling
must conform to all local codes. An auxiliary
drain pan if required by code, should be at
least four inches larger than the bottom of
the heat pump.
