PROTECTION
Once the units are properly positioned on the jobsite, cover them
with either a shipping carton, vinyl film, or an equivalent protec
-
tive covering. Cap open ends of pipes stored on the jobsite. This
precaution is especially important in areas where painting, plaster
-
ing, or spraying of fireproof material, etc. is not yet complete. For
-
eign material that accumulates within the units can prevent proper
start-up and require costly clean-up operations. Before installing
any of the system components, be sure to examine each pipe, fit
-
ting, and valve, and remove any dirt or foreign material found in
or on these components.

DUCT FLANGES
The unit heat pumps feature foldout return and supply air duct
flanges. These fold-out flanges allow the heat pumps to more easi
-
ly fit through doorways and other tight spaces, and also prevent
damage in shipping and handling.
It is recommended that all fold-out flanges be folded out once the
heat pump is installed to ensure that return and supply airflow is
not obstructed. These flanges can be easily folded using standard
or duckbill pliers. Once folded out these flanges can be used to
support light ductwork loads.
VERTICAL UNITS (50PSV)
Vertical units should be mounted level on a vibration absorbing
pad slightly larger than the unit base in order to minimize vibration
transmission from the unit to the building structure. See Fig. 3. It
is generally not necessary to anchor the unit unless required by lo
-
cal code.
All major service access for the vertical models is from the front
side of the unit. When installing the unit in a confined space such
as a closet, ensure that the service panel screws are accessible,
that the filter can be replaced without damage and that water and
electrical connections are accessible. For models with a unit-
mounted disconnect switch, make sure the switch can be easily
seen and operated.
To reduce sound transmission, units should be installed using flex
-
ible electrical conduit and hose kits. Care should be taken to en-
sure that no part of the unit cabinet is touching part of the building
structure. For ducted return applications, a flexible duct connec
-
tion should be used. Mount the unit on a vibration absorption pad
slightly larger than the entire base to minimize vibration transmis
-
sion. It is not necessary to mount the unit on the floor.

HORIZONTAL UNIT (50PSH)
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. All horizontal units come with a Hanging
Bracket Kit to facilitate suspended unit mounting. Hanging brack
-
ets are installed as shown in Fig. 4.

Hanging Bracket Locations
The hanging bracket kit includes the following:
• (5) Brackets
• (5) Rubber vibration isolators
• (8) Screws #10 x 1/2 in.
• (10) Bolts 1/4 – 28 x 1/2 in. hex bolt (not used on this
model)
The following additional materials are needed and must be field-
supplied:
• Threaded rod (3/8 in. maximum diameter)
• Hex nuts
• Washers (1-3/4 in. minimum O.D.)
Hanging Bracket Installation
1. Remove and discard factory-provided screws from location
where hanging brackets will be installed. See Fig. 5.

Removing Factory Screws
2. Mount 4 brackets to unit corner post using the bolts provided
in the kit, as shown in Fig. 6. DO NOT re-use the screws
removed from the unit during Step 1 to mount the hanging
brackets on the unit.
