MAINTENANCE
Always ensure that the main external electricity supply is switched
off before attending to the servicing of your Claudgen Screen-Zone
heater.
To obtain best results from your heater it is necessary to avoid the
build up of dust and dirt within the unit and on the air inlet and
discharge grills. For this reason regular cleaning is necessary, paying
particular attention to the removal of dirt build up on the rotor
blades. A single drop of light oil should be applied to the motor
bearing from time to time.
PROTECTION (Therm l Cut-out)
The units are protected in the event of fan failure, or an obstruction
of the free airflow, by thermal TC Self Hold Cut-outs. Having
tripped, the TC cut-out remains open, effectively switching off the
heating elements, as long as mains power is available inside the
appliance.
TO RESET THE PTC SELF-HOLD CUT-OUT
DO NOT ADJUST BY HAND ANY COMPONENTS
a) The cut-out is reset by switching OFF mains power to the
appliance.
b) Allow the appliance to cool for 20 minutes.
c) Restart, switch ON the appliance. If the cut-out trips again a
qualified electrician should be consulted.
TO REPLACE A SWITCH
a) Remove the top cover.
b) Release the three fixings which secure the switch bracket to the
right hand side of the main case.
c) Remove the push-on connectors, noting their position.
d) Remove by compressing the plastic retaining tabs, and lifting
out the switch.
e) Insert the new switch, refit and push on connectors in the
correct order, test and reassemble.
TO REPLACE THE FAN HEATER ASSEMBLY
a) Remove the top cover.
b) Disconnect the internal wiring from the main terminal block and
earth stud.
c) Release the three fixings which secure the switch bracket to the
right hand of the main case.
d) Remove the four nuts and washers fixing the fan heater
assembly to the back of the case.
e) The fan heater assembly can now be eased forward and
removed from the heater case.
f) Fit replacement fan heater and reassemble in reverse order.
