ECO-Y INSTALLATION MANUAL
General Installation Information cont.
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. Horizontal units are normally suspended from a
ceiling by four or six 3/8-inch 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 Dimensions table.
Assemble the hangers to the unit as shown on page 7. 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, one bracket on the filter side
should be installed 180° from the position shown in the figure on
page 7. The unit should be pitched approximately 1/4-inch 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.

Horizontal Unit Mounting
Some residential 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-inch
diameter since they may not be strong enough
to support the unit . The rods must be securely
anchored to the ceiling .
