Service and Care
REMKO PWW units require virtually no maintenance
when operated normally. They should, however, be
checked regularly and, if necessary, cleaned, to ensure
proper operation.
1. Separate all poles of the unit from the power supply
and secure it from being switched on by unauthor-
ised persons.
It is not adequate to switch the unit off via the control
switch on the switching unit!
Initial Operation
Prior to initial operation
Prior to initial operation, the following must be com-
pleted:
1. Check that assembly is mechanically sound.
2. Check that the connection to the customer-installed
heating system is correct.
3. Make sure that hot surfaces, e.g. the supply lines,
are protected against unintentional contact.
4. Make sure that all air outlet openings are opened.
5. Activate the power supply to the switching unit and
switch the unit on via the control switch.
6. Initial operation is prohibited until it is ensured that
the proper assembly and electrical installation corre-
sponds to the provisions of the EU guidelines
89/392/EWG and 73/23/EWG.
During initial operation
1. Measure the power consumption of the fan.
The rated current may not exceed the value speci-
fied on the type plate in each switch phase.
2. Check the control/regulating function of the fan.
3. Check the function of the room thermostat.
If mounted.
4. Check that the fan is running quietly.

6. Check that the heating medium supply lines have
been properly connected and are impermeable.
2. Wait until the fan stops.
3. Turn off the flow of water and secure it from being
opened on by unauthorised persons.
4. Wait until the heat-exchanger has cooled down.
