* RDF-2 and RDF-3 sys-
tems have double hinged
doors as illustrated. Control
compartment on RDF-1 has
a single hinged door.
** Configuration is for
RDF-2 and RDF-3. The
supply connection on the
RDF-1 systems is above the
control wiring connection.
5.0 Mounting
Mounting the system is the responsibility of the installer. Verify that the supporting
structure has sufficient load-carrying capacity to support the weight.
Depending on the building and its use, determine whether or not additional measures
should be taken to reduce the effect of blower vibration and/or noise.
When selecting a location for an outdoor installation, position the unit so that the air
inlet will NOT be facing into the prevailing wind. A minimum of 14" (356mm) clearance
is required from the bottom of the air inlet hood to the mounting surface.
Prior to installation, be sure that the method of support is in agreement with all local
building codes. For both indoor and outdoor installations, check for service platform
requirements. If an outdoor system is being installed with bottom discharge and/or
return air, a full perimeter roof curb is recommended.
