The following procedures should be followed to test the WM150 for correct operation:
1. After unpacking, examine all external features to confirm damage-free shipment.
Report all defects and damage at once. Connect the power cable to a grounded 13
Amp electrical socket. Connect the drainage outlet to a suitably sized hose and run
the hose to a permanent drain.
DO NOT REMOVE COVERS WHEN THE UNIT IS IN OPERATION
2. Check dehumidification process as follows:
a. Place unit on a level surface.
b. Turn the power supply on, then turn the on / off switch to the 'I' position, note
the display will flash for approximately 1 second then show the humidity set
point for approximately 12 seconds. Also all the indicator lights will illuminate
for the same duration. After this brief period the display will show the room
humidity and all the lights will go off. The machine is now powered up (POWER
light illuminated) and ready to operate. Then carry out the following: -
c. Set the humidity set point to lowest setting (35% RH) as follows.
i. Press the UP and DOWN arrow keys together for 3 seconds and the display
will start to flash
ii. Use the UP and DOWN arrow keys to adjust the set point to 35%
iii. Press the RIGHT arrow key to save (if the RIGHT arrow key is not pressed
for 3 seconds the selection is cancelled)
iv. Once set to 35% and saved the compressor will start and the drying light
will illuminate
d. Check that the compressor is running.
e. Leave the machine running for 15 minutes.
f.
Observe the evaporator coils through the rear upper grille, to confirm frost
formation.
g. If the air temperature is below 25ºC, an even coating of frost should cover the
entire evaporator coil.
h. If the air temperature is above 25°C, frost and/or droplets of condensed water
should cover the entire evaporator coil.
i.
When the unit is operated in an ambient of less than 15°C, a defrost cycle
should occur. This will be at intervals of no more than every hour and will last
no more than 5 minutes. The exact time is impossible to predict as the unit is
fitted with a temperature sensitive defrost control. When in defrost the
DRYING lamp will extinguish and the DEFROST light illuminate. After defrost
the lights will switch back
3. After using the WM150, turn it off for 5 minutes to allow the condensate on the coils to
drain into the pump reservoir.
ONCE THE UNIT HAS BEEN SWITCHED OFF, WAIT AT LEAST
