DESCRIPTION

DH dehumidifiers have been designed for use in places which have to be dried quickly or where an uncontrolled rise in levels of relative humidity cannot be permitted.

DH dehumidifiers reduce the relative water vapour condensation level in the air.

As you can see in figure 1, each unit has a refrigeration circuit and a fan.The air which is drawn in by the fan (3) passes through the fil- ter (5) and strikes the cold walls of the evaporator (6) where it cools to a temperature which is slightly below condensation point. Some of the vapour condenses and is collected in the water tank (9). Then the air passes through the condenser (4) and is heated to a tem- perature which is slightly higher than room temperature.

Fig. 1 How the unit works:1. Air-tight compressor. 2. Control device 3. Helical fan 4. Condenser 5. Air filter 6. Evaporator 7. Tube fitting 8. Float 9. Water tank (Except DH 80).

Best results are obtained at relative humidity levels of between 40% and 100% and at temperatures that range from 3° to 40°.

A humidistat automatically controls the unit, turning it on and off when the desired level has been attained.The electronic control device (2) automatically starts and stops the defrosting process in accordance with the workings of the unit. In case of overheating due to malfunction or if the unit has been used in a place where the tem- perature exceeds the maximum permitted limit of 40°C, the control device automatically blocks the unit, the fan and compressor stop and the control lamp (b) lights up.

WARNING: If room temperature is lower than the minimum permitted value (3°C) the dehu- midifier doesn’t work and the control lamp (b) flashes.

WARNING: The mains supply to the heater (230V, monophase, 50 Hz) must be earthed and have a magneto-thermal switch with differential.

The dehumidifier should preferably be placed in the middle of the space where it will operate so that the intake and expulsion of air will not be hindered. It should be at least 20-30 cm

from any wall. It should not be placed next to sources of heat such as radiators, stoves or other heat outlets. It should not be placed near doors or openings. When the dehumidifier is working all doors and windows must be shut.

WARNING: Cloths or coverings of any kind must not be placed on the dehumidifier when it is working.

If necessary, the water tank can be removed and the water drained off directly by attaching a rubber tube to the tube fitting (7).

INSTRUCTIONS FOR USE

TURNING ON

WARNING: The dehumidifier must be used, stocked and, for DH 25, transported in a vertical position. Should this not be the case, the machine will not function properly.

To turn on the unit proceed as follows:

•Turn the hydrostat adjusting knob clockwise to 20%.

•Turn ON the green switch (a) -position “1”. The fan and compres- sor start and the switch lights up.

•Turn the hydrostat adjusting knob (d) anti-clockwise to the desired relative humidity level.

WARNING: The dehumidifier is provided with an automatic security device which starts the compressor just 1 minute after the switch (a) is on.

TURNING OFF

Turn OFF the green switch (a)-position “0”.

WARNING: If room temperature is lower than the minimum permitted value (3°C) the dehu- midifier doesn’t work and the control lamp (b) flashes.

THE WATER TANK (EXCEPT DH 80)

When the water tank is full the unit stops immediately and the pilot lamp (c) comes on. The tank must be emptied before the unit can start working again.
