COOLmax Portable Air Conditioners feature spot cooling for large areas where cooling of the entire area is not practical. A dedicated spot cooling thermostat controls the unit in this application.

This air conditioner can also be used in smaller areas for room cooling. A control panel provides ease of use and contains a self-diagnostic function and display, showing operating modes, room and set temperatures, and faults.

If an abnormal operation occurs, a visual display of the fault is shown. Caster wheels are included for easy portability. Suitable applications include: a factory or work place, industrial kitchen, computer room, emergency cooling, outdoor event, etc.



After unpacking the unit, carefully inspect unit for any damage that may have occurred during transit. Check for any loose, missing, or damaged parts.

The unit doesn’t work1.      Check the power supply to verify that power is available to the unit

2.      Verify that the power cord is connected

1.      Reset the circuit breaker and restart the unit

2.      Connect power cord

No cold air flows from the cold air outlet1.      Ambient air cannot be properly cooled if the filter is dirty and not regularly cleaned

2.      Compressor will not work if the unit is turned off and on quickly.

3.      The ambient air temperature may be too high

1.      Clean the filter
