Fig. 3 refers to the machine provided with lifting pump, which includes a water collection tank (5) and a floating ball stopping device
for full tank (6), in case the pump would not unload properly.
.
Machines provided with Hot Gas Defrosting System
The models with hot gas defrosting system have one by-pass solenoid valve and a special electronic card.
The functioning of Hot Gas Defrosting is an exclusive Fral system for the dehumidifiers: this system consists of a thermostat and one
electronic control, which use the hot gas by-pass system only when it is necessary and for the period of time required; this will
lengthen the life of the machine by reducing the hot gas functioning phases.
.
The Control Panel is always placed on the upper side of the machine and consists of 4 lights
indications:
POWER (Supply): red light which turns on when the electric power arrives at the machine;
FULL (ALARM): green light which turns on when the water tank is full, or when the lifting pump is not
working properly and then it fills up the water tank. When this light is on, the machines will stop
running.
DEFROST: red light which turns on when the compressor is in 'pause or idle' position for the
programmed delayed start off at first start up of the machine, or during the defrosting phases.
WORKING (RUNNING): red light on when the dehumidostat starts up automatically the functioning of
the machine.
May be placed on the front or rear side of the machine.
It consists of a number scale ranging from 1 to 5 or from 1 to 7. The minimum value correspond to
80%, the highest value to 20%; the intermediate value (3-4) indicates that the humidity is at approx.
55%, a suggested good general value.
In the position "CONT", the machine will keep running all the time, independelntly from the relative
humidity in the room.
In position "OFF", the machine is not running and will never start running (one-pole switch)
Before starting the dehumidifier, make sure that the machine has been standing in vertical position for at-least 8 hours. If one fails to
observe this procedure, irreparable damage may be caused to the compressor. Then one can proceed and connect the dehumidifier
plug to a 230 V - one phase power socket.
The red light 'POWER' will switch on confirming correct supply of power to the machine. If the light 'WORKING' is still off, turn
clockwise the knob on the control panel till the light 'WORKING' is ON. The light 'DEFROST (PAUSE) will also switch on and , after
about 5 minutes the dehumidifier will start dehumidifying.
When the red light is "ON" (ALARM), the machine wiil not start: one must check that the water tank be empty and, then, that be set in
correctly; with the machines provided with pump, check that the pump function be working and that the delivry pump may be clear.
AND IF THE DEHUMIDIFIER DOES NOT START OR DEHUMIDIFY ?
First make sure that the red light 'POWER' is 'ON': this means that the current is fed to the machine. If the power supply light is not
on, make sure that the connecting wire plug may be properly inserted into a main line socket in the room. After checking all this, if the
power light is still off, then call the dealers service.
Make sure that the green light 'FULL' be off; If this is not the case, check the correct position of the draining pipe (see point 4.)
Make sure that the red light 'RUNNING' be 'on'; this means that the Humidostat activates the functioning of the machine. When the
dehumidifier is set again to functioning, after an idle period due to the reaching of the preset humidity or after emptying the water
tank, if the Humidostat requires functioning of the machine, then beside the two red central lights, also the red light 'Pause' will light
up. During this 5 minutes long phase, only the motor fan is running whereas the compressor is off. This operating cycle take place
every 45 minutes to allow the defrosting of the cooler. When the red light 'Pause' will remain off for a period longer than 6 minutes,
the dehumidifier should be brought to Dealer's service centre.
When the machine appears to be working correctly ( the two central red lights are on), but it is not producing condensed water or
produces only very little condensed water, it should be checked whether the relative humidity in the room may be lower than
40.45%; if the relative humidity is higher than that, the machine should be controlvoyant by the dealer's service.
