Operation with air/water heat pumps
When operating with an air/water heat pump, particularly when
temperatures are low outside, the heat pump's buffer tank
must be at a temperature of at least 14°C to ensure that the
heat pump evaporator can defrost. You should therefore en-
sure that thawing has taken place if necessary before opening
the valves to the heating circuit.
Troubleshooting
The following causes can result in the fan convector producing
insufficient heat:
•
Red indicator flashes:
See "Fault indication" section
•
Air trapped in heat exchanger:
Disconnect device from power supply, remove casing and
bleed heat exchanger. For position of bleeder screw, see fig.
4.
•
Water temperature too low:
Set flow temperature higher on heating system.
•
Insufficient water flow rate through device:
Adjust flow rate (hydraulic balance). To do this, close ther-
mostat valves on the other heaters.
•
Dirt on heat exchanger:
Clean heat exchanger, see "Maintenance" section.
Cleaning outer surfaces
The heater must be switched off and cooled for cleaning. The
surfaces of the heater can be cleaned by wiping with a soft,
damp cloth and then dried. Do not use abrasive powder or fur-
niture polish to clean as these may damage the surface.
Maintenance – to be performed by a specialist
Dust or lint that collects inside the heater must be removed at
regular intervals.
To do this, disconnect the device from the power supply, loosen
the 4 fixing screws on the underside of the casing and carefully
remove the casing cover. Remove dirt with a soft brush or a
vacuum cleaner.
Build-up of air in the heat exchanger can be remedied by open-
ing the bleeder valve (fig. 4).
