INTRODUCTION
Designed for a wide range of applications, the RM40P 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 RM40P 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.
The unit also incorporates an integral pump which will remove the condensate
from the unit.

OPERATION
After unpacking, examine all external features to confirm damage-free
shipment. Report all defects and damage at once.
Connect the drainage outlet to a suitably sized hose and run the hose to a
permanent drain.
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.

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
IF ANY OF THE PRECEDING PROBLEMS OCCUR,CONTACT THE EBAC
SERVICE CENTER PRIOR TO CONTINUED OPERATION OF THE UNIT TO
PREVENT PERMANENT DAMAGE.
WARNING:
ENSURE THAT THE POWER CORD TO THE MACHINE HAS BEEN
DISCONNECTED BEFORE CARRYING OUT ROUTINE SERVICE. THE
SERVICING AND REPAIR OF THIS UNIT SHOULD ONLY BE CARRIED
OUT BY A SUITABLY QUALIFIED PERSON.
WARNING:
DO NOT STEAM CLEAN REFRIGERATION COILS

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.
NEVER 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.
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.
