1.2 WALL HANGING/FLOOR STANDING
DH44 MODEL
DH66 MODEL
When e dehumidifier is unpacked it is suitable for use standing on e floor. The feet can
be adjusted to allow for unevenness in e surface. If e unit is to be mounted on a wall, e
complete package contains wall brackets and antivibration buffers. Once e unit has been hung
on e wall e floor stand arrangement can be removed. Access to e fixings for e stand
arrangement can be gained by removing e round grommets in e feet.

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

2.2 ELECTRICAL CONNECTION
The electrical connection should be carried out by an auorised electrician, paying special
attention to e latest IEE regulations. In any case, e mains power supply should be fitted wi
a 30mA/30ms protection switch. The cable access position can be selected by e customer
from e positions shown above. Once e desired knockout has been removed a cable gland
(supplied in package) can be fitted to neaten off e hole.
The electric box is situated under e compressor cover which will need to be removed.
The connections are made to e terminal box on e outside of e electric box in e
bottom right hand corner of e dehumidifier.
The machine should be installed in accordance wi EMC2004/108/EC.
FAN MODE SWITCH
A fan mode switch is positioned on e electric box wi e following modes:
Fan continuous - continuous operation of e fan.
Fan cycle - e fan will be switched on and off automatically by e humidistat.
The mode “fan cycle” helps, especially wi a covered swimming pool, to save energy:
(but in is mode larger humidity swings may be experienced).
Aer connecting e electrical supply, e compressor cover and machine cover need to be
installed in e manner shown on page 5.
The dehumidifier is now ready to operate.
Attention. The dehumidifier should not be switched on wiout it’s covers in place.
Operation wiout a cover causes poor airflow. Due to safety features e unit will switch off aer
a short period of time.

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