INTRODUCTION
Designed for a wide range of applications, the RM4500 is a rugged, industrial
unit, which utilizes an energy-efficient compressor and a compact portable
design to provide easy efficient drying.
The RM4500 has a number of special features:
•
High efficiency rotary compressor
•
EIPL’s “Reverse Cycle” defrost system
•
Hours run meter
•
Integral pump out system
•
Provision for permanent drainage
•
Extra long power cord
•
Robust rotational moulded polyethylene housing
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 RM4500 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.
A digital Humidistat is included which allows for precise humidity control. A
programmable display lets you set a specific desired humidity level.
The unit incorporates a rotational moulded polyethylene shell resilient to
damage caused by rough handling.

OPERATION
The following procedures should be followed to test the RM4500 for correct
operation:
1. After unpacking, examine all external features to confirm
damage-free shipment. Report all defects and damage at once. Connect the
power cable to a grounded 13 Amp electrical outlet. Connect the drainage
outlet to a suitably sized hose and run the hose to a permanent drain.
2. Setting the Digital Humidistat
The Digital Humidistat is factory preset to give the optimum
level of control. Only adjustment of the desired set point is
required.
During normal operation, the display shows the current % Relative
Humidity within the space being conditioned.
The required humidity level can be set as follows:
• Press the “S” button once to access the set point
• Press the ▲ or ▼ button to change the display to the
desired Humidity level
• Press the “S” button again to save the set point – The
control returns to displaying the current % Relative
Humidity
3. Check dehumidification process as follows:
A. Place unit on a level surface.
B. Start up unit by switching to “I”.
C. Check that the compressor is running.
D. Leave the machine running for 1 Hour.
E. Operate the pump purge switch and ensure water is pumped
out of the condensate outlet tube located on the back of the
unit.
CAUTION:
DO NOT REMOVE COVERS WHEN UNIT IS IN OPERATION

F. When the unit is operated in ambient of less than 15°C, a
defrost cycle should occur approximately every 20mins. The
exact time is impossible to predict as the unit is fitted with a
temperature sensitive defrost control.
When the unit is defrosting, the % Relative Humidity displayed on the
digital controller may increase as a result of the ice / frost melting. This
is quite normal and the display will return to its normal reading when the
unit returns to dehumidifying mode. (Fan running)
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.
After using the RM4500, turn it off for five minutes to allow the condensate on
the coils to drain into the pump reservoir, then turn it back on and press the
momentary purge switch for twenty to thirty seconds to evacuate the water
from the pump reservoir.
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, maintenance
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 remove front cover and 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
20mins. 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
I
F ANY OF THE PRECEDING PROBLEMS OCCUR, CONTACT THE EBAC
S
ERVICE 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 internal
pipework.
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.

This product contains fluorinated greenhouse gases covered by the Kyoto
Protocol. The refrigeration system is hermetically sealed.
The Global Warming Potential (GWP) of refrigerants used in products
manufactured by Ebac Industrial Products Ltd is as follows
R134a – 1300
R407c – 1610
For type and weight of refrigerant contained in this unit, please refer to the
product data label
Due to the high pressures within the refrigeration circuit, under no
circumstances must direct heat be applied to the evaporator coil in an attempt
to remove the build-up of ice.
No attempt should be made to cut open any part of the refrigeration circuit
due to high pressures and gas involved.
If the unit is switched off at the mains power supply for any reason, the unit
must be allowed to stand at rest for at least three minutes before restarting.
For correct installation and operation the unit inlet and outlet must have a
clearance of 0.5M from all adjacent surfaces and or structures.
