INSTALLATION INSTRUCTIONS
WALL MOUNTING INFORMATION
1. These units are secured by wall mounting brackets
which secure the unit to the outside wall surface at
both sides. A bottom mounting bracket is provided for
ease of installation, but is not required.
2. On wood-frame walls, the wall construction must be
strong and rigid enough to carry the weight of the unit
without transmitting any unit vibration.
3. Concrete block walls must be thoroughly inspected to
insure that they are capable of carrying the weight of
the installing unit.
MOUNTING THE UNIT
1. Two holes, for the supply and return air openings, must
be cut through the wall as shown in Figure 3.
2. Locate and mark lag bolt locations and bottom
mounting bracket location, if desired. See Figure 3.
3. Mount bottom mounting bracket, if used.
4. Hook top rain flashing under back bend of top. Top
rain flashing is shipped attached to the back of the unit
on the right side.
5. Position unit in opening and secure with 5/16 lag bolts;
use 7/8 inch diameter flat washers on the lag bolts.
6. Secure rain flashing to wall and caulk across entire
length of top. See Figure 3.
7. For additional mounting rigidity, the return air and
supply air frames or collars can be drilled and screwed
or welded to the structural wall itself (depending upon
wall construction). Be sure to observe required
clearance if combustible wall.
8. On side by side installations, maintain a minimum of
20 inches clearance on right side to allow access to
heat strips and control panel and to allow proper
airflow to the outdoor coil. Additional clearance may
be required to meet local or national codes.

WIRING — MAIN POWER
Refer to the unit rating plate for wire sizing information
and maximum fuse or “HACR Type” circuit breaker size.
Each The disconnect access door on this unit may be
locked to prevent unauthorized access to the disconnect.
To convert for the locking capability, bend the tab located
in the bottom left hand corner of the disconnect opening
under the disconnect access panel straight out. This tab
will now line up with the slot in the door. When shut, a
padlock may be placed through the hole in the tab
preventing entry.
WIRING — LOW VOLTAGE WIRING
230/208V, 1 phase and 3 phase equipment dual primary
voltage transformers. All equipment leaves the factory
wired on 240V tap. For 208V operation, reconnect from
240V to 208V tap. The acceptable operating voltage
range for the 240 and 208V taps are:
Five (5) wires should be run from thermostat subbase to
the 24V terminal board in the unit. A five conductor, 18
gauge copper, color-coded thermostat cable is
recommended. The connection points are shown in Figure
10.
OPERATING VOLTAGE RANGE
NOTE: The voltage should be measured at the field
power connection point in the unit and while
the unit is operating at full load (maximum
amperage operating condition.)
