ASTON COMPACT INSTALLATION MANUAL
Installing Horizontal Units
Remove and discard the compressor hold down shipping bolt
located at the front of the compressor mounting bracket prior to
setting the unit in place. Horizontal units are available with side or
end discharge.
NOTE
: Left (Right) Return Side Discharge cannot be converted to
Left (Right) Return End Discharge or vice versa, without additional
custom sheet metal parts. Horizontal units are normally suspended
from a ceiling by four (009-060 models) or five (070-072 models)
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 Hanger Bracket Dimensions
table. 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. To allow filter access, install hanger brackets
as illustrated in the Hanger Bracket Locations section. The unit
should be pitched approximately 1/4 in. towards the drain in both
directions to facilitate the removal of condensate. 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.
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.
