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 .
