Water Drainage Method

This air conditioner is equipped with the very latest MIST technology which means the water tank nearly never fills, hence water drainage will generally only be required at the end of the season (see START-END OF SEASON OPERATIONS in page 19. However the MIST technology does not operate when the unit is in HEAT mode. Thus the tank may still require emptying in HEAT mode.

NOTE: As a safety measure to positively prevent water spillage the air conditioner is equipped with a fail safe device if the water tank fills. The unit will completely stop, the control panel displays ft (FULL TANK) as mentioned on SELF DIAGNOSIS in page 17. The compressor and fan will not restart until the tank has been drained.

Cleaning The Filters

To keep your air conditioner working efficiently, you should clean the filters every week of operation. The evaporator filter can be removed as shown in Fig. 12.

The condenser filter is two pieces.

  • STEP 1: Take out one filter as shown in Fig. 13.
  • STEP 2: Take out other filter as shown in Fig. 14 and Fig. 15.

Use a vacuum cleaner to remove dust accumulations from the filters. If it is very dirty, immerse in warm water and rinse a number of times. The water should be luke warm. After washing, leave the filters to dry then re-insert.
