CAUTION
DO NOT store or install units in corrosive environments or in
locations subject to temperature or humidity extremes (e.g., at-
tics, garages, rooftops, etc.). Corrosive conditions and high
temperature or humidity can significantly reduce performance,
reliability, and service life. Always move units in an upright
position. Tilting units on their sides may cause equipment
damage.
CAUTION
Failure to remove shipping brackets from spring-mounted
compressors will cause excessive noise and could cause com-
ponent failure due to added vibration.
Step 3 — Locate Unit
• Locate the unit in an indoor area that allows easy removal
of the filter and access panels, and has enough room for
service personnel to perform maintenance or repair.
• Provide sufficient room to make fluid, electrical, and duct
connection(s).
• If the unit is located in a confined space such as a closet, pro-
visions must be made for return air to freely enter the space.
• Unit condensate drains are not internally trapped. Allow
room below the unit base for horizontal models for an ade-
quate condensate trap.
• Horizontal units include two condensate drain connections
to allow flexibility in unit sloping for proper drainage.
Only one connection needs to be used. The unused connec-
tion must be plugged.
• These units are not approved for outdoor installation; there-
fore,they must be installed inside the structure being condi-
tioned. Do not locate units in areas that are subject to freezing.
• Units must be installed in conditioned space that is not
subject to extremes of temperature or humidity to avoid
cabinet sweating and/or equipment damage.
• Do not use units for temporary heating, air conditioning or
ventilation during construction or remodeling, especially
when plastering, sanding or painting or when replacing
carpet or flooring. Dust and debris can clog the coil and
blower. Chemical vapors can lead to formicary corrosion
and damage the coil. Ensure adequate ventilation and de-
bris collection during construction or remodeling.
IMPORTANT: Care must be taken to prevent the introduction
of dust, paint, debris, or chemicals into the unit, which can
cause damage to the unit, delay start-up, and may impact unit
longevity.
Step 4 — Mount the Unit
CAUTION
Remove all shipping blocks under blower housing. Loosen
compressor mounting bolts. Failure to do so could result in
equipment damage.

MOUNTING VERTICAL UNITS

Vertical units are available in front or rear return configurations.
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. See Fig. 8.
All 50VQP units should be vibration isolated according to the de-
sign engineers' specifications.

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 rods are usually attached to the unit
corners by hanger bracket kits. (See Fig. 9.) The rods must be se-
curely anchored to the ceiling. Refer to the hanging bracket as-
sembly and installation instructions (Included with the unit) for
details. All 50HQP units include an integral angle iron frame with
mounting holes present. (See unit horizontal detail drawing.) Hor-
izontal 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. Plumb-
ing connected to the heat pump must not come in direct contact
with joists, trusses, walls, etc.
Fig. 9 — Typical Horizontal Unit Hanging Bracket
Some applications require an attic floor installation of the horizon-
tal 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
connected to this secondary pan should be run to an eave at a loca-
tion that will be noticeable. If the unit is located in a crawl space,
the bottom of the unit must be at least 4-in. above grade to prevent
flooding of the electrical parts due to heavy rains.
