Basic setting fan speed
The fan speed when the door is open is set
using the control. Note that the air flow
direction and fan speed may need fine
adjustment depending on the loading of the
door.
Filter (W)
The water coil is protected against dirt and
blockage by an air filter which covers the
coil face. In environments where the filter
needs cleaning often, it is advisable to use an
external intake filter (see accessories pages),
which provides an easier maintenance, since
the unit does not need to be opened.
Service, repairs and maintenance
For all service, repair and maintenance first
carry out the following:
1. Disconnect the power supply.
2. Loosen the screws and raise the front panel.
The front is blocked in open position with
the front hatch hook, see fig 1A or removed
completely, see fig. 1B. The service hatch is
removed by loosening the screws.
3. After service, repairs and maintenance fasten
the service hatch and the front. When the
front has been removed it it important to be
sure it is firmly seated in the front locks again,
see fig. 1B.
Maintenance
Unit with water heating:
The appliance filter should be cleaned
regularly to ensure the air curtain effect and
the heat emission from the device. How often
depends on local circumstances. A clogged
filter is not a risk, but the appliance function
can fail.
1. Disconnect the power.
2. Loosen the screws and raise the front panel.
The front is blocked in open position with the
front hatch hook, see fig 1A.
3. Remove the filter and vacuum clean or wash
it. If the filter is clogged or damaged, it may
need to be changed.
Overheating
The air curtain unit with electric heater is
equipped with an overheat protector. If it is
deployed due to overheating, reset as follows:
1. Disconnect the electricity with the fully
isolated switch.
2. Allow the electrical coil to cool.
3. Determine the cause of overheating and
rectify the fault.
4. Connect the air curtain again.
All motors are equipped with an integral
thermal safety cut-out. This will operate,
stopping the air curtain should the motor
temperature rise too high. The cut-out
will automatically reset when the motor
temperature has returned to within the
motor’s operating limits.
Temperature control
Temperature control of SIRe maintains the
exhaust temperature. If the temperature
should exceed the preset value anyway
the overheating alarm goes off. For more
information see the manual for SIRe.
All units:
Since fan motors and other components are
maintenance free, no maintenance other than
cleaning is necessary. The level of cleaning
can vary depending on local conditions.
Undertake cleaning at least twice a year. Inlet
and exhaust grilles, impeller and elements
can be vacuum cleaned or wiped using a
damp cloth. Use a brush when vacuuming
to prevent damaging sensitive parts. Avoid
the use of strong alkaline or acidic cleaning
agents.
