Compressor protection
• To protect the unit from unnecessary wear the compressor will only turn on three minutes
after power on or restart and it will continue to run for 3 minutes after power off. DO NOT
unplug the unit till the compressor has stopped.
This air conditioner has an auto-water-evaporating system. Condensed-water is transferred to the
hot exhaust air and vented through the hose. This will not only improve cooling efficiency, but also
save energy.
If inner water tank does become full, "W.F." will flash on the display and the Water Full LED will
illuminate. At the same time the machine will enter standby mode and a buzzer will be heard. The
compressor will stop and no keys can be pressed on the display until the internal tank has been
emptied.
To empty the water tank, switch the unit off by pressing the Power button, wait for three minutes
then disconnect from the mains supply. Place a drainage pan underneath the drain pipe (at the
bottom, rear of the unit in the center). Remove the drain cap and withdraw the bung, allow the
water to drain into the drainage pan. Replace the bung and cap then reconnect the unit to the mains
supply.
In very humid environments it is possible the tank may fill more frequently, under these
circumstances it may be easier to fit a continuous drain. To do this attach a suitable pipe to the drain
port and run to drain.
