4. UNIT ALARMS
5. FIRST STARTING OF MACHINE
Before starting the dehumidifier, make sure that the machine has been standing in vertical position
for at-least 5 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 115 V - one phase
power socket.
If the dehumidifiers is still off, set a lower value of humidity on the control panel .
After about 3 minutes the dehumidifier
will start dehumidifying.
6. 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.
