INTRODUCTION

Designed for a wide range of applications, the RM75 DV 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 RM75DV 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 RM75 DV unit is fitted with a transformer which will allow the unit to operate on either 110volts or 230volts 1ph 50hz power supply.
This unit is fitted with a screw-type in-line fuse holder with a 5amp anti-surge fuse.
All electrical components within the dehumidifier are rated for 110 volts, for safety reasons. The Voltage change over (selector switch) switch, can be found through the front air off the grille
The unit incorporates a rotationally molded 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.
Connect to a grounded 110V / 230V electrical outlet. When a generator is used to supply the power, it is essential to check the minimum kva required, refer to the unit rating plate.
To protect the compressor, you should allow 5 minutes between switching the dehumidifier off and on again.

PERMANENT DRAINAGE

For this, you will need a length of PVC tubing 10mm internal diameter.
Disconnect your dehumidifier from the power supply before fitting a permanent drainage tube. Feed tubing through the grommet hole on the rear of the unit and onto the visible drain point.
Tubing should be run to a suitable drainage point, ensuring that the tube doesn’t rise above the tubing outlet point on the rear of the unit, otherwise flooding may occur.

CHECK DEHUMIDIFICATION PROCESS AS FOLLOWS:

CAUTION: DO NOT REMOVE COVERS WHEN UNIT IS IN OPERATION

Place the unit on a level surface.
Start up the unit by switching to “I” and humidistat fully clockwise
Check that the compressor is running.
Leave the machine running for 15 minutes.
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.
When the unit is operated in 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.

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.

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 the continued full efficiency of the dehumidifier, service procedures should be performed as follows:

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.
- 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 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.
Check all wiring connections, including mains cable for damage or loose connections.
To check the defrost operation, the unit needs to be operated at 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 before defrosting 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 BEFORE CONTINUED OPERATION OF THE UNIT TO PREVENT PERMANENT DAMAGE.

REPAIRS

Should an electrical component fail, consult the Factory Service Centre 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 Centre before 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 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:
- 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 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.
