Operate the air conditioner for five (5) to ten (10) minutes. No excessive noise or vibration should be
evident during this run period. The condenser blower (ambient air), the evaporator blower (enclosure air),
and the compressor should be running.
Condenser air temperatures should be warmer than normal room temperatures within a few minutes.
The compressor is provided with automatic reset thermal overload protection. This thermo-switch is
located and mounted inside the plastic enclosure clipped to the compressor. The switch operates when
the compressor overheats due to clogged or dirty inlet air filter or if ambient air temperatures exceed
nameplate rating or if enclosure dissipated heat loads exceed the rated capacity of the air conditioner.
The thermal overload switch will actuate and stop compressor operation. The blowers will continue to
operate and the compressor will restart after it has cooled to within the thermal overload cut-in
temperature setting.
INSTALLATION
Step 1: Inspect air conditioner. Verify functionality before mounting the air conditioner, see Handling &
Testing the Air Conditioner on page 1.
Step 2: Using the cutout dimensions shown in this manual, prepare the air "IN" and air "OUT" openings,
and mounting bolt hole pattern for the enclosure.
Step 3: Using the gasket kit provided, install gaskets to air conditioner. See gasket kit illustration in this
manual for proper location.
Step 4: Mount air conditioner on enclosure using mounting bolts and washers provided to secure unit to
enclosure. Allow unit to remain upright for a minimum of five (5) minutes before starting. Caution: Air
conditioner must be in upright position during operation.
Step 5: Refer to top of nameplate for electrical requirements. Connect the power cord to a properly
grounded power supply. Use of an extension cord is not recommended. Electrical circuit should be fused
with slow blow or HACR circuit breaker.
Step 6: When the unit is equipped with an automatic temperature controller, the controller is preset at the
factory for your convenience and should not require adjustment.
SYSTEM CONTROLS
Figure 1
Level I Temperature Controller
The Level I controller is located inside the air conditioner. To adjust, disconnect
power to the air conditioner. Open the front panel by loosening the front panel
screw. Refer to figure 2 (page 4) to locate the controller. Turn the controller
adjustment screw slot counter-clockwise to increase and clockwise to decrease
the temperature set pint (see figure 1). The thermostat cooling setpoint is
indicated by the alignment of the adjustment screw slot with the dial decal. After
completing adjustment, close the front panel and tighten the front panel screw.
Restore power to the air conditioner for operation.
Level II and III Temperature Controller
The Level II and III controller mounted on the air conditioner front panel and is
factory set for standard operation. All operating parameters are programmable for
custom applications. Refer to the Level II and III programming and Operating
Instruction Manual, 10-1008-161 (standard) or 10-1008-162 (low ambient).
