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 lter and access panels. Provide sufcient
room to make water, electrical, and duct connection(s).
If the unit is located in a conned 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 difcult 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 specications catalog 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
specic series and model in unit specications 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.
2.
Provide access to hanger brackets, water valves and
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.
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 soft using eld supplied, threaded rods
sized to support the weight of the unit.
Use four (4) eld supplied threaded rods and factory
provided vibration isolators to suspend the unit. Hang the
unit clear of the oor slab above and support the unit by the
mounting bracket assemblies only. DO NOT attach the unit
ush with the 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.
