2. The unit needs to be horizontally level.
3. At least 200mm away from ceiling and corners of e room.
4. At least 200mm service access is required.
5. If e dehumidifier is positioned on a wall, e wall needs to be load bearing. (A
plasterboard or wood cladded wall is not suciently strong).

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.

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).

4.2 OPTIONAL LPHW
Connect e flow and return water circuit pipe work by means of e 15mm stubs which are
provided on e side of e machine. The connections project 40mm out from e le hand side
of e DH44 and e right hand side of  DH66.
Attention! Flow - bottom connection
Return - top connection
The 3 way, motorised, diverting valve fitted to machines wi e LPHW option is operated
by a remote 12V AC air temperature ermostat (available from Calorex).
When e valve is energised e flow is rough e LPHW coil.
When e valve is unenergised e flow is diverted.
NOTE :- When e fan switch is set to cycle and e fan is not running, a demand on e
LPHW valve will cause e fan to automatically start.

b. Wipe clean wi a damp clo or cleaning fluid suitable for polyeureane.
Cleaning
The evaporator and e condenser will need to be cleaned occasionally wi a so brush.
It is also necessary to check if e driptray and e condensate drain contain any dirt which
may impair satisfactory operation. Calorex recommends at e maintenance should be done
annually by a specialised dealer.
Note The reply paid warranty registration card must be returned to ensure e correct
warranty is given. If you do not find a registration card wi your machine please contact e
CALOREX service department giving your name, address, and e serial number of your machine.
A card will en be sent to you for your completion.
Heal and Safety
As e Heat Pump contains electrical and rotational equipment, it is important at ONLY
competent persons carry out any work on is type of machine (see warranty).
Before opening e unit you must ensure at e mains supply is isolated
Machine not running at all
Check e following:
Is e supply switched on?
Is e supply fuse healy?
Turn e humidistat dial fully anti-clockwise.
Check e air inlet and oulet for obstructions.
If, aer carrying out e above and waiting 1 hour e machine does not start phone for
service.
Machine Fan only running
Turn humidistat dial fully clockwise
Check air inlet and oulet for obstructions, if aer waiting 30 minutes e machine does not
start phone for service.
Water leaking from base of unit
Check connection from machine to drain for blockages and clear accordingly, check fall is
adequate.
Check at machine is bo vertically and horizontally level.
The user checklist should be carried out before initiating a service call.
Do not attempt to interfere wi any internal control setting as ese have been factory
calibrated and sealed.
Any sign of abnormal operation such as water dripping should be reported immediately to
an installer or Calorex.
