INTRODUCTION
Designed for a wide range of applications, the RM40 is a rugged, industrial
unit, which utilizes an energy-efficient compressor and a compact portable
design to provide easy efficient drying.
The fan draws the moist air through the cold evaporator coil, which cools the
air below its dew point. Moisture forms on the evaporator coil and is collected
in the condensate tray, which is equipped with a permanent drain. The cooled
air then passes through the hot condenser coil where it is reheated using the
same energy removed during the cooling phase, plus the additional heat
generated by the compressor. The air is, therefore, discharged from the
dehumidifier at a slightly higher temperature with a lower absolute humidity
than that which entered. Continuous circulation of air through the
dehumidifier gradually reduces the relative humidity within the area.
The RM40 dehumidifier is a rugged, reliable drying unit designed to operate
effectively over a broad range of temperature and humidity conditions. An
active hot gas defrost system, controlled by an electronic timer, guarantees
positive de-icing, thereby optimizing operation at low temperatures.
The unit incorporates a rotational moulded polyethylene shell resilient to
damage caused by rough handling.

OPERATION
After unpacking, examine all external features to confirm damage-free
shipment. Report all defects and damage at once.
Before connecting it to the mains you should ensure that the humidistat is
turned fully anti-clockwise. Connect to a grounded 15A standard household
electrical outlet then the humidistat control should be turned clockwise until
you hear the unit operate. To protect the compressor, you should allow 5
minutes between switching the dehumidifier off and on again.
OPERATING THE HUMIDISTAT
The humidistat works in a similar way to a central heating thermostat, but
instead of measuring temperature, it measures the amount of moisture in the
air. You may select the level of moisture you require (known as Relative
Humidity) and the unit will operate to achieve that level and then switch off.
As a general guide, the higher the setting the lower the Relative Humidity will
be before the machine switches off. Therefore the machine will operate longer
to achieve this. If the dehumidifier switches off and drying is not complete it is
possible that the humidistat setting is too low and may need increasing.
Conversely, if you no longer have condensation and the unit is still operating,
then the humidistat setting may need reducing.
EMPTYING THE WATER CONTAINER
When the water container is full an internal float mechanism will switch the
unit off. This is indicated by the illumination of the “full” light on the front
control panel. The water container is at the rear of the unit. To empty the
container, carefully remove the water container. When emptied replace
PERMANENT DRAINAGE
When your dehumidifier is to be used constantly in one area, it can be fitted to
drain continuously, eliminating the need to empty the water container. Ideal
when the property is to be left unoccupied.
For this you will need a length of PVC tubing, 10mm internal diameter.
Disconnect your dehumidifier from the power supply before fitting permanent
drainage. Remove the water container; remove the blind grommet on the back
face of the unit and then the blanking bung from the drainage point visible
through the hole. Feed tubing through hole where grommet was located and
onto the visible drain point. Lastly fit the blanking bung to the drain point on
the underside of the drain tray. The water container can be replaced whilst the
drainage kit is in use for safe storage

USE OF PERMANENT DRAINAGE
When in use tubing should be run to a suitable drainage point, ensuring that
the tube doesn’t rise above the drain tray, otherwise flooding may occur.
CHECK DEHUMIDIFICATION PROCESS AS FOLLOWS:
1. Place unit on a level surface.
2. Start up unit by switching to “I” and humidistat fully clockwise
3. Check that the compressor is running.
4. Leave the machine running for 15 minutes.
5. Observe the evaporator coils through the rear grille, to confirm frost
formation or weeping.
• If the air temperature is below 25°C, an even coating of frost should
cover the entire evaporator coil.
• If the air temperature is above 25°C, frost and/or droplets of
condensed water should cover the entire evaporator coil.
6. When the unit is operated in ambient of less than 15°C, a defrost cycle
should occur approximately every hour. The exact time is impossible to
predict as the unit is fitted with a temperature sensitive defrost control.
If, after carrying out the above procedures, the unit does not appear to
function properly, refer to the Trouble Shooting section, which follows,
or contact the Factory Service Center.
CAUTION:
DO NOT REMOVE COVERS WHEN UNIT IS IN OPERATION
CAUTION:
ONCE THE UNIT HAS BEEN SWITCHED OFF, WAIT AT
LEAST FIVE MINUTES BEFORE RESTARTING.

ROUTINE SERVICE
To ensure continued full efficiency of the dehumidifier, service procedures
should be performed as follows:
1. Clean the surface of the evaporator and condenser coils by blowing the
dirt out from behind the fins with compressed air. Hold the nozzle of the
air hose away from the coil to avoid damaging the fins. Alternatively,
vacuum clean the coils.
2. Check that the fan rotates freely. The fan motor is sealed for life and
therefore does not need oiling.
3. To check the refrigerant charge, run the unit for 15 minutes and observe
the evaporator coil. It should be evenly coated with frost across its
surface. At temperatures above 25°C, the coil may be covered with
droplets of water rather than frost. Partial frosting accompanied by
frosting of the thin capillary tubes, indicates loss of refrigerant gas or low
charge.
4. Check all wiring connections, including mains cable for damage or loose
connections.
5. In order to check the defrost operation, the unit needs to be operated in
an ambient temperature of less than 15°C for at least 1 hour. When
operated In this condition the unit should defrost at least once every
hour. The defrost mode can be monitored by observing the ice melting
on the coil face, prior to defrost the face will show a white coating of
frost, which should clear during defrost

REPAIRS
1. Should an electrical component fail, consult the Factory Service Center
to obtain the proper replacement part.
2. If refrigerant gas is lost from the machine, it will be necessary to use a
refrigeration technician to correct the fault. Contact the Factory Service
Center prior to initiating this action.
Any competent refrigeration technician will be able to service the
equipment. The following procedure must be used:
a. The source of the leak must be determined and corrected.
b. The machine should be thoroughly evacuated before recharging.
c. The unit must be recharged with refrigerant measured accurately
by weight.
d. For evacuation and recharging of the machine, use the crimped
and brazed charging stub attached to the side of the refrigerant
compressor.
The charging stub should be crimped and rebrazed after servicing.
N
EVER
allow permanent service valves to be fitted to any part of the
circuit. Service valves may leak causing further loss of refrigerant
gas.
3. The refrigerant compressor fitted to the dehumidifier is a durable unit
that should give many years of service. Compressor failure can result
from the machine losing its refrigerant gas. The compressor can be
replaced by a competent refrigeration technician.
Failure of the compressor can be confirmed by the following procedure:
a. Establish that power is present at the compressor terminals using a
voltmeter.
b. With the power disconnected, check the continuity of the internal
winding by using meter across the compressor terminals. An open
circuit indicates that the compressor should be replaced.
c. Check that the compressor is not grounded by establishing that a
circuit does not exist between the compressor terminals and the
shell of the compressor.
