Proceed as follows:
• Connect the pressurized vessel to the motorconden-
ser, and the motorcondenser to the pliers.
• Punch a hole in the compressor's exit tube and leave
the pliers in position.
• Open both motorcondenser taps, turn it on and empty
the refrigeration circuit.
• Stop the motorcondenser and close both taps. Then
close the tap on the pressurised vessel.
• Remove the pliers.
• If the pressurized vessel is full it should be given to a
company that specializes in the disposal of waste
fluids.
OBSERVED FAULT, POSSIBLE CAUSES AND REMEDIES
Problem
• The unit won't start
• The ventilator and compressor are working but
neither water nor ice form on the walls of the
evaporator
• The unit stops and the pilot lamp (c) comes on • Water tank full
• The unit stops and the control lamp (b) comes
on (the condenser's ribbed battery has over
heated)
• The unit stops and the control lamp (b) flashes • Temperature lower than 3°C
tubes should be elimimated and lock bolts removed. Then
drill a hole in the underside of the chassis, and pour the
mineral oil into a vessel which should be delivered to a com-
pany that specializes in the recycling and disposal of oil.
nium and steel can be recycled or scrapped.
Cause
• No electricity
• Humidistat not set correctly
• Water tank full (pilot light "c"on)
• Air flow not sufficient
• Room temperature and relative humidity level
too low.
• Refrigeration circuit not working correctly
• Air flow obstructed
• Air temperature above 40 °C
• Fan motor broken
• Refrigeration circuit not working correctly

Remedy
• Check that the the switch is working and that it
is ON
• Check mains caracteristics (220V, 1 ~, 50 Hz)
• Set the humidistat at a relative humidity level
which is lower than the room humidity level
• Empty the water tank.
• Check that nothing is blocking intake and
expulsion of air
• Check that there aren't any deposits or
incrustation on the filter or on the ribbed batteries
of the condenser or of the evaporator
• Check that the temperature is between 0° and
40° and that relative humidity is between 40%
and 100%.
• Call an Authorised Service Technician
• Empty the water tank
• Remove obstacles to air flow and start unit
again
• Only use unit when temperature drops below 40
°C
• Call an Authorized Service Technician
• Call an Authorized Service Technician
• Move the dehumidifier in a place where
temperature is 3°C
