ofthelterandaccesspanels.Leaveaminimumof18"
of clearance around the heat pump for easy removal,
and to perform routine maintenance, or troubleshooting.

connections.
2. The contractor should make sure that adequate ceiling
panel access exists, including clearance for hanger
brackets,ductcollarsandttings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.
Do not use rods smaller than shown in Figure 3. The rods must
be securely anchored to the ceiling or to the bar joists.
CAUTION
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 Figure 3.
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.
