HORIZONTAL INSTALLATION

Mounting Horizontal Units

Horizontal units have hanger kits pre-installed from the

factory as shown in ﬁ gure 1. Figure 3 shows a typical

horizontal unit installation.

Horizontal heat pumps are typically suspended above

a ceiling or within a sofﬁ t using ﬁ eld supplied, threaded

rods sized to support the weight of the unit.

Use four (4) ﬁ eld supplied threaded rods and factory

provided vibration isolators to suspend the unit. Hang the

unit clear of the ﬂ oor slab above and support the unit by

the mounting bracket assemblies only. DO NOT attach

the unit ﬂ ush with the ﬂ oor 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.

NOTICE! Failure to remove shipping brackets

from spring-mounted compressors will cause

excessive noise, and could cause component

failure due to added vibration.

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 ﬁ lter and access panels.

Provide sufﬁ cient room to make water, electrical, and

duct connection(s).

If the unit is located in a conﬁ ned 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 difﬁ cult 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 speciﬁ cations catalog for dimensional data.

Conform to the following guidelines when selecting

unit location:

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 speciﬁ c series and model in unit

speciﬁ cations catalog. 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.

Provide access to hanger brackets, water valves

and ﬁ ttings. 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.
