Horizontal Installation
Mounting Horizontal Units
Horizontal units have hanger kits pre-installed from the factory
as shown in Figure 1. Figure 3 shows a typical horizontal unit
installation.
Horizontal heat pumps are typically suspended above a ceiling
or within a soffit using field supplied, threaded rods sized to
support the weight of the unit.
Use four (4) field supplied threaded rods and factory provided
vibration isolators to suspend the unit. Hang the unit clear of the
floor slab above and support the unit by the mounting bracket
assemblies only. DO NOT attach the unit flush with the floor
slab above.
Pitch the unit toward the drain as shown in Figure 2 to improve
the condensate drainage. On small units (less than 2.5
tons/8.8kW) ensure that unit pitch does not cause condensate
leaks inside the cabinet.

Horizontal Unit Location
Units are not designed for outdoor installation. Locate
the unit in an INDOOR area that allows enough space
for service personnel to perform typical maintenance or
repairs without removing unit from the ceiling. Horizontal
units are typically installed above a false ceiling or in a
ceiling plenum. Never install units in areas subject to
freezing or where humidity levels could cause cabinet
condensation (such as unconditioned spaces subject
to 100% outside air). Consideration should be given to
access for easy removal of the filter and access panels.
Provide sufficient room to make water, electrical, and
duct connection(s).
If the unit is located in a confined space, such as a closet,
provisions must be made for return air to freely enter the
space by means of a louvered door, etc. Any access panel
screws that would be difficult to remove after the unit is
installed should be removed prior to setting the unit. Refer
to Figure 3 for an illustration of a typical installation. Refer
to unit engineering design guide for dimensional data.
In limited side access installations, pre-removal of the
control box side mounting screws will allow control box
removal for future servicing (HB units only).
Conform to the following guidelines when selecting
unit location:
1. Provide a hinged access door in concealed-spline
or plaster ceilings. Provide removable ceiling
tiles in T-bar or lay-in ceilings. Refer to horizontal
unit dimensions for specific series and model in
unit submittal data. Size the access opening to
accommodate the service technician during the
removal or replacement of the compressor and the
removal or installation of the unit itself.
2. Provide access to hanger brackets, water valves
and fittings. Provide screwdriver clearance to access
panels, discharge collars and all electrical connections.
3. DO NOT obstruct the space beneath the unit with
piping, electrical cables and other items that prohibit
future removal of components or the unit itself.
4. Use a manual portable jack/lift to lift and support the
weight of the unit during installation and servicing.
The installation of water source heat pump units and all
associated components, parts and accessories which
make up the installation shall be in accordance with
the regulations of ALL authorities having jurisdiction
and MUST conform to all applicable codes. It is the
responsibility of the installing contractor to determine and
comply with ALL applicable codes and regulations.
