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 controlled by the dealer's service.
6. CONNECTION TO A DRAIN PIPE - LIFTING PUMP (optional)
This dehumidifier can be connected directly with a fixed draining
pipe; in this case, the water tank must be removed to allow the
connection of the pipe to the connection fitting.
For the connection, use one pipe provided with a ¾
” female
fitting at one end (fig.1).
In the machines with ball-cock, if the water tank is not fitted in,
the machine will not work.
Some machines have a switch in order to allow the functioning
without water tanks, in other machines it
’s necessary to modify
the tongue-shaped device placed near the ball-cock.
In the machines with tank placed in the front the supplied rubber
device must be used to block the microswitch lever which is
located on the left upper side of the water tank towards the front
part.

Machines with condensed water lifting pumps
This machine includes a condensed water lifting pump.
Put the rubber pipe of the pump supply in a waste pipe or similar. Pay attention
that the pipe be no choked up because of eventual narrow bends.
The pump will work automatically, controlled by a ball cock placed inside the
pump.
Before moving the machine, push the button placed on the pump to empty the
tank of the pump.
If the pump cannot work correctly, the compressor stops and the green light
turns on. In this case, check the pipe situation. Maximum head working
pressure of the pump is about 3.5-4 meters.
Pay attention to have inserted the tank or to have connect the pipe before starting the
machine!
7. PERIODICAL MAINTENANCE
AIR FILTER CLEANING
The only required periodical maintenance is the cleaning of the filter
once every month,
or more often if the environment is very
dusty or the dehumidifier is working for many hours every day.
The cleaning must be done by placing the filter under a water jet with the drilled panel facing the floor so that the water jet may push
the filter towards the drilled panel.
After a few years running, may be necessary to make a cleaning of the warm heat exchanger (condenser) by using compressed air.
This operation must be done by a specialized technician. This cleaning will improve the performances and the long life of the
machine.
Note: You can require spare filters from your dealer's service.
