2.3 INSTALLATION
The unit must be installed with the prescribed
clearances for service as shown in Figure 2.1.
The minimum clearance dimensions, required by
AERCO, are listed below. Local building codes
may require more clearance and take
precedence
Minimum clearances required:
Sides
24"
Front 18"
Rear 18"
Top 18"
All gas piping, water piping, and electrical
conduit or cable must be arranged so that they
do not interfere with the removal of any cover, or
inhibit service or maintenance of the unit.
WARNING!
KEEP UNIT AREA CLEAR AND FREE
FROM COMBUSTIBLE MATERIALS AND
FLAMMABLE VAPORS AND LIQUIDS .
2.3.1. SETTING THE UNIT
Locate the lifting lugs, shipped with the unit and
attach them to the 5/8” x 11 studs at the top of
the unit. Remove the unit from the wooden skid
and place in position using a block and tackle or
hoist attached to the lifting lugs, (see Fig. 2. 2).
USE ONLY THE LIFTING LUGS TO MOVE
THE UNIT.
The KC-1000 is U/L approved for installation on
combustible flooring. A 4” to 6" high
housekeeping concrete pad is recommended
and allows for sufficient drainage of the
condensate.
It is suggested that units be secured using the
holes provided in the frame base. Piping must
not be used to secure the unit in place. See
drawing AP-A-568 in Appendix F for the base
frame dimensions.
In multiple unit installations, it is important to
plan the position of each unit. Sufficient space
for piping connections and future maintenance
requirements must be given. All piping must
include ample provision for expansion.
If installing a Combination Control, (CCP),
system, it is important to identify and place the
Combination Mode units in the proper physical
location.
