POWER CONNECTION
To avoid possible damage to the air conditioner, it must be in an
upright (horizontal) position for a minimum of five (5) minutes
before start up.
CAUTION
Refer to the nameplate for proper electrical frequency, current and voltage requirements, then connect to
a properly grounded and fused electrical circuit. See Wiring Schematic on page 8 for location of power
connection.
NOTE: No other equipment should be connected to this circuit to prevent overloading.
Additional isolation may be required if the equipment nearby is susceptible to line noise or
voltage fluctuation.
STARTUP PROCEDURE
•
Verify the unit has been upright for five (5) minutes.
•
Operate the air conditioner for ten (10) minutes. No excessive noise or vibration should be evident during this run
period. The condenser fan, evaporator or cool air fan, and the compressor should be running. To check cool air
output, use a reliable air temperature measuring device. The cool air output should be between 50 F to 60 F when
room temperature is between 70 F to 80 F.
•
These units are equipped with a thermostat. If the thermostat is not set properly the condenser fan and compressor
may not operate while the evaporator fan runs. If this condition exists, the entering air temperature to the evaporator
may be below the thermostat setpoint. To correct, set the thermostat setting to a lower setpoint, until the condenser
fan and compressor start.
•
The compressor is provided with automatic reset thermal overload switch. This switch is located and mounted inside
the plastic enclosure clipped to the compressor. This switch will be activated whenever the compressor overheats.
Excessive heat buildup may be caused by:
1. Clogged or dirty inlet air filter.
2. Ambient air temperatures exceeding nameplate rating.
3. Enclosure heat load exceeding the rated capacity of the air conditioner.
The thermal overload switch will actuate and stop compressor operation. Blowers will continue to operate,
however, and the compressor will restart when it has cooled to within the thermal overload cut−in temperature
setting.
