Immediately after applying power, the evaporator blower (enclosure air) should start
running. Operate the air conditioner with the compressor running for five (5) to ten
(10) minutes. You will need to set the cooling controller set point below the ambient
temperature to operate the compressor.
Condenser air temperatures should be warmer than normal room temperatures
within a few minutes after the condenser impeller(s) starts.
If electrical power to the air conditioner is interrupted and reapplied, the compressor
may take up to five (5) minutes to restart due to the high back pressure of the
compressor.
DOOR SWITCH
The door switch terminal block on the back of the unit includes a jumper that is used
only if the door switch option is not used. Several door switches may be connected
in series and operated on one cooling unit. The door switch only supports a floating
connection, no external voltages. Remove the jumper from terminals 3 and 4 of the
connector, and connect the door switch to the two terminals if the door switch is
available.
SURFACE MOUNTING
Air conditioner must be in upright position during operation.
CAUTION
1. Using the mounting gasket kit provided with the unit, install gasket to the air
conditioner, see Figure 3.
2. See Figure 5 or Figure 6 or Figure 7 or Figure 8 or Figure 9 for the enclosure
cutout diagrams, depending on the unit being installed.
3. Screw the supplied grub screws into the blind nuts on the rear of the unit, see
Figure 4.
4. Secure the unit using the supplied washers and nuts.
5. Mount the air conditioner to the enclosure being careful not to damage the
mounting gasket. The mounting gasket is the seal between the air conditioner
and the enclosure. Avoid dragging the air conditioner on the enclosure with the
mounting gasket attached as this could cause rips or tears in the gasket.
6. Allow unit to remain upright for a minimum of five (5) minutes before starting.

SMART CONTROLLER
The controller is wired and programmed at the factory to be energized when power is
applied to the air conditioner. Adjust the controller to the desired cabinet temperature.
The factory default cooling differential for controllers that are set-up for °C, or for °F,
are as follows:
Cooling Set-point
Turn-on
Turn-off
35°C
