200 MINIMUM
For optimum performance of the dehumidifier, care needs to be taken when considering it’s
position.
1. Good air circulation.
2. The unit needs to be horizontally level.
3. At least 200mm away from ceiling and corners of the room.
4. At least 200mm service access is required.
5. If the dehumidifier is positioned on a wall, the wall needs to be load bearing. (A plaster-
board or wood cladded wall is not sufficiently strong).

1) N.B. THE RCD IS AN EARTH LEAKAGE TRIP & ALTHOUGH NOT ALWAYS REQUIRED
IT IS RECOMMENDED THAT IT IS USED ON ALL INSTALLATIONS. (A 30mA RCD SHOULD BE USED).
IF THE UNIT IS WITHIN 1,25M

THEN IT MUST BE 2,5M ABOVE
THE POOL SURFACE.

When the dehumidifier is unpacked it is suitable for use standing on the floor. The feet can be
adjusted to allow for unevenness in the surface. If the unit is to be mounted on a wall, the
complete package contains wall brackets and antivibration buffers. Once the unit has been
hung on the wall the floor stand arrangement can be removed. Access to the fixings for the
stand arrangement can be gained by removing the round grommets in the feet.

2.1 CONDENSATE DRAIN CONNECTION
The condensate output and electrical connections can be at either end of the machine, at the
side or in the back, depending on the requirements of the user. To gain access to the unit
remove the covers, unscrewing the fixing screw in both end mouldings.The driptray can be
removed and turned round. Remove the desired knockouts, insert grommet (supplied) and
route condensate pipe through the knockout.(Tube outside diameter 19mm).

POSITION OF
ELECTRIC BOX
The electrical connection should be carried out by an authorised electrician, paying special
attention to the latest IEE regulations. In any case, the mains power supply should be fitted with
a 30mA/30ms protection switch. The cable access position can be selected by the customer
from the positions shown above. Once the desired knockout has been removed a cable gland
(supplied in package) can be fitted to neaten off the hole.
The electric box is situated under the compressor cover which will need to be removed.
The connections are made to the terminal box on the outside of the electric box in the bottom
right hand corner of the dehumidifier.
FAN MODE SWITCH
A fan mode switch is positioned on the electric box with the following modes:
Fan continuous - continuous operation of the fan.
Fan cycle - the fan will be switched on and off automatically by the humidistat.
The mode “fan cycle” helps, especially with a covered swimming pool, to save energy:
(but in this mode larger humidity swings may be experienced).
After connecting the electrical supply, the compressor cover and machine cover need to be
installed in the manner shown on page 5.
The dehumidifier is now ready to operate.
Attention. The dehumidifier should not be switched on without it’s covers in place. Operation
without a cover causes poor airflow. Due to safety features the unit will switch off after a short
period of time.

3.0 HUMIDISTAT SETTINGS
The dehumidifier is provided with automatic control by a humidistat that can be adjusted to suit
room requirements. Adjustment is by a dial that is located on the right hand side of the unit. The
dial is marked as % relative humidity. When the % relative humidity is lower, the air is drier.
To set the dial, turn it so that the requred room humidity is positioned adjacent to the reference
mark as shown below. A room relative humidity of 50% to 60% is recommended. To operate the
dehuidifier continuously or to test its operation, turn the dial to the 20% position. In this position
the fan and compressor will run continuously (after the initial 6 minute time delay).
