VERSATEC BASE 50Hz SERIES INSTALLATION MANUAL
Installing Horizontal Units
Horizontal units are available with side or end discharge
and may be easily field converted by flipping the blower
discharge panel. Horizontal units are normally suspended
from a ceiling by four 3/8 in. diameter threaded rods. The
rods are usually attached to the unit by hanger bracket kits
furnished with each unit. Lay out the threaded rods per
the dimensions below. Assemble the hangers to the unit as
shown. Securely tighten the brackets to the unit using the
weld nuts located on the underside of the bottom panel.
When attaching the hanger rods to the bracket, a double
nut is required since vibration could loosen a single nut.
NOTE: The unit should be pitched approximately 1/4
in. towards the drain in both directions to facilitate the
removal of condensate.
Horizontal Unit Mounting
Use only the bolts provided in the kit to attach hanger
brackets. The use of longer bolts could damage internal
parts. Some applications require the installation of
horizontal units on an attic floor. In this case, the unit
should be set in a full size secondary drain pan on top of a
vibration absorbing pad. The secondary drain pan prevents
possible condensate overflow or water leakage damage to
the ceiling. The secondary drain pan is usually placed on a
plywood base isolated from the ceiling joists by additional
layers of vibration absorbing material. Insulate supply
plenum and use at least one 90° elbow and flexible duct
collar to reduce noise.
CAUTION: Do not use rods smaller than 3/8 in.
diameter since they may not be strong enough
to support the unit. The rods must be securely
anchored to the ceiling.
