INTRODUCTION
Designed for a wide range of applications, the RM85 is a rugged, industrial
unit, which utilizes an energy-efficient compressor and a compact portable
design to provide easy efficient drying.
The RM85H has a number of special features:
•
High efficiency rotary compressor
•
EIPL’s “Hot Gas” defrost system
•
Digital Humidity Control
•
Integral pump out system
•
Provision for permanent drainage
•
Extra long power cord
•
Robust rotational moulded polyethylene housing
•
Separate outlets allowing dry air to be ducted
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 RM85 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.
This appliance is not intended for use by persons (including children) with
reduced physical, sensory or mental capabilities, or lack of experience and
knowledge, unless they have been given supervision or instruction concerning
use of the appliance by a person responsible for their safety. Children should
be supervised to ensure that they do not play with the appliance.
If the SUPPLY CORD is damaged, it must be replaced by the manufacturer,
its service agent or similarly qualified person in order to avoid hazard.

OPERATION
The following procedures should be followed to test the RM85H for correct
operation:
1. After unpacking, examine all external features to confirm damagefree shipment. Report all defects and damage at once. Connect the
power cable to a grounded 15 Amp electrical outlet.
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. Ensure the Humidity Control is set to 40%
C. Check that the compressor is running.
D. Leave the machine running for 15 minutes.
E. Observe the evaporator coils through the front grille, to confirm
frost formation.
(i) If the air temperature is below 78°F, an even coating of frost
should cover the entire evaporator coil.
(ii) If the air temperature is above 78°F, frost and/or droplets of
condensed water should cover the entire evaporator coil.

F. When the unit is operated in ambient of less than 59°F, a
defrost cycle should occur approximately every ½ hour. The
exact time is impossible to predict as the unit is fitted with a
temperature sensitive defrost control. During this defrost cycle
the fan will switch off.
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.
ONCE THE UNIT HAS BEEN SWITCHED OFF, WAIT AT
LEAST FIVE MINUTES BEFORE RESTARTING.
After using the RM85H, turn it off for five minutes to allow the condensate on
the coils to drain into the pump reservoir, then press the momentary pump
purge switch for twenty to thirty seconds to evacuate the water from the pump
reservoir.

ROUTINE MAINTENANCE
ENSURE THAT THE POWER CORD TO THE MACHINE HAS BEEN
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
2. Check that the fan rotates freely. The fan motor is sealed for life and
3. To check the refrigerant charge, run the unit for 15 minutes and observe
4. Check all wiring connections.
5. In order to check the defrost operation, the unit needs to be operated in

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
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.
