MC20 Operating Instructions

On the front of the unit, you will find 3 buttons - Power, Fans, and Cooling, along with a thermostat. The 2 lights indicate power, and condensate tank full.


To switch the air conditioning unit on, first turn on the fans. The power light should be on. To begin cooling, switch on the cooling cycle using the cooling button and turn the Thermostat to 'Max'. There will be a time delay before the compressor switches on and the unit begins to cool. This is a safety feature, to protect the unit.

Once the room has reached your desired temperature, rotate the thermostat anticlockwise until the compressor switches off. The thermostat will now keep the room at this temperature.

When the condensate tank fills up the warning light will show. The tank should be slid from the back of the unit, and emptied. When replacing the tank, ensure it is inserted into the unit the right way round.

User Maintenance

The following items should be carried out at least on a weekly basis to ensure trouble free & optimum performance of the air conditioning unit.

  • Remove tank from the side of the air conditioning unit and empty
  • Unclip filter from back of unit and remove loose deposits with a vacuum cleaner or brush.
  • If at any time the unit is switched off, it may take up to 5 minutes before cooling is resumed.
