Immediately upon uncrating the unit, check for any damage that may have been
incurred during shipment. If damage is found, document the damage with the trans-
porting agency and contact your Reznor Distributor. This unit was inspected at the
factory immediately prior to crating.
Check the blower cabinet plate to be sure that the electrical characteristics of the
blower cabinet are compatible with the installation site.
Be sure all shipped-separate options for the installation are available. Shipped-sep-
arate options could include a roof curb, an outside air hood, a disconnect switch, an
evaporative cooling module, and/or freeze protection kit for an evaporative cooling
module.

Weight - Before installing the blower cabinet, check the supporting structure to verify
that it has sufficient load-carrying capacity to support the weight. Model RBL weighs
488 lbs (221 kg).
Depending on the building structure and its use, determine whether or not measures
should be taken to reduce the effect of blower vibration and/or noise. Determining the
need for and installing vibration isolation is the responsibility of the installer.
Suspending Indoor
Cabinet
Blower cabinets may be suspended using field-furnished rod hangers. Insert 1/2" rods
into the holes at the corners of the curb cap. Attach rods to the unit as illustrated in
FIGURE 2. Attach rods to the building structure. Proper suspension of this cabinet is
the responsibility of the installer.
