Before installing, check the supporting structure to be sure that it has sufficient load-
bearing capacity to support the weight of the unit during installation and operation.
Lifting and mounting are the responsibility of the installer.
* Cooling coil cabinet
module weight is
estimated for heaviest
coil. If more accurate
information is needed,
check with your
distributor or Reznor ®

5.2 Mounting Model RHH is designed to be mounted on a roof curb.
Model RDH, REH, and RXH outdoor systems are designed to be mounted on a roof
or a cement slab. The system may be set directly on a slab without any additional sup-
port. When installed on a roof, either a manufacturer-designed roof curb, a manufac-
turer-designed roof curb adapter (required if replacing a Reznor ® Model RGB or RPB),
a field-supplied roof curb, or other field-supplied support is required.
NOTE: A roof curb is recommended with a downturn plenum and/or bottom return air
to provide a weatherproof installation.
