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).
1.1 MOUNTING, POSITION

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.

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).

TRANSPORT BLOCK
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.
The machine should be installed in accordance with EMC2004/108/EC.
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).

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

AIR FILTER SIZES
The optional air filter is situated behind the front covers, in front of the evaporator fins and is
accessed by removing the covers. Undo the screw in each side moulding and lift off covers.
This should only be done with the power turned OFF.
From time to time it may be necessary to remove the filter for cleaning purposes. All that is
needed to clean the filter is to remove it and wash it in warm soapy water. Reinstall the filter
when dry.

A normal humidistat setting of 50-60% RH, marked on the dial provided.
Minimum air temperature DH44/66A is 15ºC
Minimum air temperature DH44/66AX is 5ºC
Note on “X” models fan stops during defrost.
On models with LPHW, fans will start automatically as required.
5.2 SERVICE NOTES
Maintenance
a. Ensure air inlet/outlets are kept clean. Air filters are available.
b. Wipe clean with a damp cloth or cleaning fluid suitable for polyeurethane.
Cleaning
The evaporator and the condenser will need to be cleaned occasionally with a soft brush. It is
also necessary to check if the driptray and the condensate drain contain any dirt which may
impair satisfactory operation. Calorex recommends that the maintenance should be done
annually by a specialised dealer.
Note The reply paid warranty registration card must be returned to ensure the correct warranty
is given. If you do not find a registration card with your machine please contact the CALOREX
service department giving your name, address, and the serial number of your machine. A card
will then be sent to you for your completion.
Health and Safety
As the Heat Pump contains electrical and rotational equipment, it is important that ONLY
competent persons carry out any work on this type of machine (see warranty).
Before opening the unit you must ensure that the mains supply is isolated
Machine not running at all
Check the following:
Is the supply switched on?
Is the supply fuse healthy?
Turn the humidistat dial fully clockwise.
Check the air inlet and oulet for obstructions.
If, after carrying out the above and waiting 1 hour the machine does not start phone for service.
Machine Fan only running
Turn humidistat dial fully clockwise
Check air inlet and oulet for obstructions, if after waiting 30 minutes the 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 that machine is both vertically and horizontally level.
The user checklist should be carried out before initiating a service call.
Do not attempt to interfere with any internal control setting as these have been factory
calibrated and sealed.
Any sign of abnormal operation such as water dripping should be reported to an installer or
Calorex.
