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 the rubber bung from the back of the unit & drain any excess water that has collected in the condensate tank.
  • Clean the air filter with a vacuum cleaner, whilst still fixed to the unit
  • If at any time the unit is switched off, it may take up to 5 minutes before cooling is resumed, when switched on again. During this time the light which indicates that the unit is set to cool will flash. The light continuously ON indicates that any time delay is complete and cooling has commenced.
