Unit Location
1. Locate the unit in an area that allows for easy removal
of the filter and access panels. Leave a minimum of 18”
of clearance around the heat pump for easy removal,
and to perform routine maintenance, or troubleshooting.
Provide sufficient room to make water, electrical and duct
connections.
2. The contractor should make sure that adequate ceil
-
ing panel access exists, including clearance for hanger
brackets, duct collars and fittings at water and electrical
connections.
3. Allow adequate room below the unit for a condensate
trap and do not locate the unit above pipes.
4. Each unit is suspended from the ceiling by four threaded
rods. The rods are attached to the unit corners by a hanger
bracket through a rubber isolator.
Caution: Do not use
rods smaller than shown in Figure 1B. The rods must
be securely anchored to the ceiling or to the bar
joists.
5. Each unit is furnished with a hanger kit. The kit is shipped
unassembled and includes hanger brackets, rubber
isolators, washers, bolts and lock washers. Lay out the
threaded rods per the dimension in Figures 1A and 1B.
6. When attaching the hanger rods to the unit, a double nut
is recommended since vibration could loosen a single
nut. The installer is responsible for providing the hex nuts
when installing hanger rods.
7. Leave minimum 3" (76 mm) extra threaded rod below the
double nuts or minimum 3" (76 mm) clearance between
top of unit and ceiling above to facilitate top panel remov-
al for servicing.
