EBAC 10560HD-GB Dual Voltage RM85-H Industrial Dehumidifier
INTRODUCTION
Designed for a wide range of applications, the RM85H is a rugged, industrial
unit, which utilizes an energy-efficient compressor and a compact portable
design to provide easy efficient drying.
The RM85 has a number of special features:
- High-efficiency rotary compressor
- EIPL’s “Hot Gas” defrost system
- Hours run meter
- Integral pump out system
- Provision for permanent drainage
- Robust rotational moulded polyethylene housing
- Extra long power cord
- 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 RM85H 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.
- The unit is fitted with a transformer which will allow the unit to operate on either 110volts or 230volts 1ph 50Hz power supply. The unit is factory set at 110 volts.
- All electrical components within the unit are rated for 110volts, for safety reasons.
The unit can easily be adjusted to operate from a 230 volt power supply as
follows:
Warning: ensure the unit is switched OFF and isolated form the supply.
The voltage selector switch is located at the rear of the machine – see
diagram on Page 4.
Remove the lower screw and swing the cover to one side to reveal the access
hole. The switch lever can be seen through the hole. Using a flat blade
screwdriver move the switch lever down to the 230 volt position. (If 110 volt
is required the switch lever must be in the upper position)
Once the required voltage has been selected, refit the cover and tighten the
lower fixing screw.
The dehumidifier is now ready to be connected to the required power supply.
BACK SHELL REMOVAL

OPERATION
The following procedures should be followed to test the RM85 for correct operation:
-
After unpacking, examine all external features to confirm damage-free shipment. Report all defects and damage at once. Ensure the correct voltage has been selected. Connect the drainage outlet to
-
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 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
-
Check the dehumidification process as follows:
CAUTION:
DO NOT REMOVE COVERS WHEN THE UNIT IS IN OPERATION
- Place the unit on a level surface.
- Start-up unit by switching to “I”.
- Check that the compressor is running.
- Leave the machine running for 15 minutes.
- Observe the evaporator coils through the front grille, to confirm frost formation.
- If the air temperature is below 25ºC, an even coating of frost should cover the entire evaporator coil.
- If the air temperature is above 25ºC, frost and/or droplets of condensed water should cover the entire evaporator coil.
- When the unit has operated an 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.
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.
CAUTION:
ONCE THE UNIT HAS BEEN SWITCHED OFF, WAIT AT LEAST FIVE MINUTES BEFORE
RESTARTING.
After using the RM85, 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.
ROUTINE SERVICE
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.
To ensure continued full efficiency of the dehumidifier, maintenance procedures should be performed as follows:
-
Clean the surface of the evaporator and condenser coils by blowing the dirt out from behind the fins w ith compressed air. Hold the nozzle of the air hose away from the coil to avoid damaging the fins. Alternatively, vacuum clean the coils.
WARNING: DO NOT STEAM CLEAN REFRIGERATION COILS -
Check that the fan rotates freely. The fan motor is sealed for life and therefore does not need oiling.
-
To check the refrigerant charge, run the unit for 15 minutes and observe the evaporator coil It should be evenly frost coated 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
-
Check all wiring connections, including mains cable for damage or loose connections.
-
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.
REPAIRS
-
Should an electrical component fail, consult the Factory Service Center to obtain the proper replacement part.
-
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:- The source of the leak must be determined and corrected.
- The machine should be thoroughly evacuated before recharging.
- The unit must be recharged with refrigerant measured accurately by weight.
- 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 brazed 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.
-
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:- Establish that power is present at the compressor terminals using a voltmeter.
- With the power disconnected, check the continuity of the internal winding by using a 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.
