USER AND MAINTENANCE MANUAL
1.
SAFETY WARNINGS
This machine is an electric appliance functioning in low tension (230/400V). The installation
must be carried out according to the norms and regulations in force concerning the
positioning of the machine.
Before proceeding with installation, please, read the following safety norms and also all
indications and instructions which are written on the machine itself.
This dehumidifier must be connected using earthed electrical plugs as required for all
electrical appliances; FRAL Company declines any responsibility for any danger or
damage whenever this norm is not complied with.
Any intervention on the machine using any instrument must be carried out only by a
qualified technician.
When the machine is connected to power, it must be in vertical position and rough
handling must be avoided because it could cause water to come into contact with
electrical components. It is therefore recommended to disconnect power before moving
the dehumidifier.
If water does come into contact with the machine, the dehumidifier must be turned off
and can be started up again after 8 hours.
Correct Distance: this dehumidifier draws in air from the back and lets it out through the
front side grille, therefore the back panel, which supports the air filter, must be kept at a
minimum distance of 15cm from the wall.
The dehumidifier must not operate in narrow areas, which do not allow a proper diffusion in
the room of air exiting the grille. The dehumidifier can be positioned with the sides near the
walls.
This dehumidifier has been designed and manufactured in compliance with the strictest
safety rules. Therefore, pointed instruments (screw drivers or similar) are not to be inserted
in the grille or in the opening of the back panel when it is opened to remove the filter.
The machine must not be cleaned using water: to clean use a wet cloth. Remember to
disconnect the plug from the socket beforehand.
The front panel should always be uncovered.
The filter should be cleaned periodically (normally every month), but in dusty rooms it
should be cleaned more often (see chapter 7). Remember that when the filter is dirty, the
air circulation and, consequently, the machines performance will be reduced.

MACHINE DESCRIPTION
DEHUMIDIFIERS WORKING DOWN TO 20% RELATIVE HUMIDITY
This machine is a special dehumidifier which can control simultaneously temperature and
humidity.




It is equipped with a particular system for heat recovery before and after the evaporator.
This enables the machine to reach very low relative humidity levels with very high energy
efficiency and saving that is 30-60% higher than that obtained with traditional
condensation dehumidifier.
This machine can often replace the use of dessicant dehumidifiers with lower costs and
problems.
Its structure is in aluminium profiles with enclosed panels in stark galvanized painted steel
sheet and has a high efficiency filter and a high displacement motor fan.
Its main applications are: where the drying process must be working down at 20%
Relative Humidity and 15-20°C.
Main components of the machine
 Coolant Compressor with its own carter electric resistance of 50W.
 Axial Fan for the dispersion of the heat in excess.
 Partializing electro valve of the internal condenser (reduces the internal
condenser size, if room temperature increases excessively).
 kW Integrating Electric Resistors becomes operative when the room temperature is
getting excessively lower.
 Humidity control with Relative Humidity sensor which activates the compressor
 Temperature Controlling System which controls the indoor temperature by
activating, in a sequence, the compressor, the partializing valve of the external
condenser and external motor fan.
4.1
Important Advice
The machine must be connected to power at least three hours before start up.
One light, close to the switch breaker shows that the machine is correctly
powered. The machine should be started up only after three hours by operating
on its specific switch.
This delayed start will allow the compressor carter resistors to cause the
evaporation of the residual liquid refrigerant which might be inside the compressor
oil. The failure to comply with this procedure may cause the breaking of the
compressor, invalidating any warranty.
4.2
Functioning of the machine
When the machine is in operation, the centrifugal motor fan will be working all the
time. The dehumidifier is provided with 3 speeds, but, once the suitable speed is
selected by operating on the motor fan terminal boxes, then the speed must not
be changed.
A 20% relative humidity value and a 27°C temperature value will be preset.
Whenever the preset relative humidity or temperature is reached, the compressor
will start up. If the temperature drops the electro valve will be activated which will
increase internal condensor surface, ensuring a bigger dispersion of the internal
heat. If the temperature continues to drop this will activate the electric resistors
(optional).
Vice versa, if the temperature increases, there will be the disconnection of the
electric resistors and of the electro-valve in sequence.
Whenever the temperature continues to increase, the external fan motor will be
activated. There is a safety thermostat that will bypass the electronic control if the
temperature of the external condenser reaches 54°C. In this case the fan motor
will go at maximum speed.
5.
MAINTENANCE
The only periodical maintenance required is the filter cleaning to be carried out
weekly.
6.
POSSIBLE FAILURES
The power light is on, the machine has been started, but main centrifugal fan is not
starting working: check phase sequence (light of phase control is flashing).
HPS light is ON: reactivate the high pressure meter (failure due to an excess of
temperature); if the problem persists, inform the service agent.
LPS is ON: Low Pressure Meter intervention. Probably the machine has no pressure.
Call the service agent.
Water drainage blocked: Check the drainage outlet is not obstructed and no
obstructions in the hose.

2) MANUAL / 0 / AUTOMATIC:
I.
Manual: In this position the machine is turned on.
II.
0: OFF (machine is off)
III.
Automatic: the machine can be turned on with a remote control through two clear
contacts (optional).
3) PHASE: if there is a reversed phase the fuse light is activated.
4) LPS: if there is low pressure because of loss of gas or ice below the battery for example, the LPS
indicator is activated.
5) HPS: indicates high pressure inside the refrigerator circuit.
6) HUMIDITY: indicates humidity levels inside the room. When the desired humidity level is
reached, the machine will turn off.
7) TEMPERATURE CONTROLLER: The temperature controller will check the inside temperature of
the room. If the temperature is too high it will trigger the axial fans to dissipate excess heat
proportionally to the temperature inside the room. (The second condenser inside the
machine is ducted outside to disipate excess heat). When the temperature inside the room
increases it will increase in speed to disipate the excess heat. If the temperature drops the first
condesnder inside the machine will automatically activate the electrovalve. This will increase
the internal condensor surface, ensuring a bigger dispersion of the internal heat. If the
tempertature continues to fall the electronic resistors (optional) will be activated.
8) DEFROST: When the temperature inside the evaporator falls below 0 °C this will start up the
battery defrost. If this happens the compressor will be off and the centrifugal fan will be in on
position.
