To switch off the dehumidifier, irrespective of its current
operating status, use exclusively the Control panel.
After switching off the dehumidifier:
– Set the remote switch to “Off” (if present)
– Switch off the terminal units by setting the switch on
each appliance to “Off”
– Set the main electrical breaker to “Off”
– Close the water shut-off cocks.
If the room temperature might fall below zero this
means there is a risk of freezing.
In this case the hydraulic circuit must be emptied,
or it must protected by adding antifreeze (such as
ethylene glycol) in the amounts recommended by
the antifreeze producer.
CHECKS DURING AND FOLLOWING COMMISSIONING
PROLONGED DISUSE OF THE APPLIANCE
– The unit is operating within the recommended
operating conditions (see Operating Limits table).
– There are no air pockets in the hydraulic circuit.
– The refrigerant compressor stops and subsequently
restarts.
When the unit is set in operation for the first time, check
that:
– The compressor is not emitting anomalous noise.
– 10 minutes after first start-up check that the air
temperature in the room is close to the temperature
of the treated air outlet. If it is not, adjust the flow rate
of water to the pre and post-treatment coils
– The compressor current input is below the maximum
rating shown in the Technical Data table.
