Horizontal Installation
Mounting Horizontal Units
Horizontal units have 4 hanger brackets partially attached
at the factory, one at each corner. Enclosed within the unit
there is a hanger kit hardware bag containing vibration
isolation grommets, washers, screws and a hanger
installation instruction page. One additional screw from
the hardware bag must be added to each hanger bracket
before unit installation.Tighten each screw to 75 in-lbs
(8.5 Nm). See Figure 1. Refer to the hanger installation
instruction page contained in the hardware bag for details
of final hanger bracket attachment and unit suspension.
See Figure 1a.
Use four (4) field supplied threaded rods and factory
provided vibration isolators to suspend the unit. Safely
lift the unit into position supporting the bottom of the
unit. Ensure the top of the unit is not in contact with any
external objects. Connect the top end of the 4 all-thread
rods, slide rods through the brackets and grommet then
assemble washers and double nuts at each rod. Ensure
that the unit is approximately level and that the threaded
rod extends past the nuts.
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 submittal data or engineering design guide for
dimensional data.
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, control, or blower assembly.
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.
