AUTOMATIC DEFROST
5.3.1.
At low room temperatures, frost may build up at the evaporator during operation. The unit will automatically start defrosting and the
POWER LED (fig.5.4) blinking. The defrost control sequence is as follows:
5.3.2.
When the unit operates in the cooling and dehum. modes and the ambient temperature sensor senses the evaporator coil temperature
is below -1°C, the compressor will stop operating for 10 minutes. The coil temperature then rises up to 7
operating mode.
5.3.3.
When the unit operates in the heating and dehum. modes, once the coil temperature sensor senses the temperature of the evaporator
is below 40
C and the differential temperature between coil temperature and room temperature is below 19
o
operated for 20minutes, the unit will start defrosting for 5 minutes and the power indicator will be blinking.
5.4.
OVERLOAD PROTECTION
5.4.1.
In the event of a power loss, to protect the compressor, there is a three minute delay until the unit restarts.
5.5.
DRAINAGE
WARNING! DO NOT attempt using either form of drainage without first removing the power supply from the unit.
‰
5.5.1.
The unit will stop working when the water receptacle is full. See Troubleshooting section for error codes.
5.5.2.
The unit has two methods of drainage. these are continuous (fig.7) or manual (fig.8).
5.5.3.
To operate in continuous mode, remove the plastic bung in the back of the machine (fig.6) and firmly insert the supplied hose.
5.5.4.

6. MAINTENANCE
NOTE: repair of unit and handling of refrigerant must only be carried out by a suitably qualified person.
6.1.
GENERAL MAINTENANCE
Turn the unit OFF and disconnect it from the mains power supply before cleaning or performing maintenance.
6.1.1.
Inspect the unit on a regular basis and replace or repair any damaged parts. Use recommended parts and an
authorised service agent. Unauthorised parts may be dangerous and will invalidate the warranty.
DO NOT use any solvents or abrasive material to clean the plastic exterior of the unit. Use only a damp soft
8
cloth for cleaning and dry the unit afterwards with a clean, dry, soft cloth.
6.2.
AIR FILTER. Clean the air filters every two weeks for optimum performance. The filters are situated at the
rear of the unit (fig.8), and are held in place by plastic frames.
6.2.1.
UPPER FILTER
Using the finger grip, pull the top edge gently outwards to release the holding lugs and remove the filter frame.
6.2.2.
LOWER FILTER
Undo fixing screw (fig.8) and pull the frame gently outwards to release the holding lugs and remove filter frame.
6.2.3.
Once released, vacuum the frames gently if clogged with dirt.
6.2.4.
If the filter is heavily soiled, it can be washed in warm water containing a mild, neutral detergent. Ensure that the filter
is dry completely before re-installing it.
6.2.5.
Refitting the filter frames into the machine is the reverse order of 6.2.1./6.2.2.
6.3.
STORAGE
6.3.1.
If the unit is not to be used for a long period of time, drain off any water in the tank. Place a large enough container under the rear of
the unit, remove the rubber drainage stopper (fig.8) to allow the tank to drain. When the tank is empty, replace the stopper firmly. Clean
the unit and air filter as above, and store in a safe, dry area, out of the reach of children.
