Electrical supply and connections
The electrical installation may only
be carried out by an appropriately
qualified person in accordance with
the current Rules and Regulations
in force.
This appliance must be earthed.
Check that the electrical specification is in
accordance with the specified data on the
air heater. All electrical connections must be
made in the heater control compartment (refer
to Figures 6 and 7). Connections must be in
accordance with the terminal markings and the
wiring diagram affixed to the unit.
The maximum cable inlet size is 6mm
2
.
The minimum external control required for
the unit is a room thermostat capable of
providing a 0-10V DC signal to the burner. It is
essential that the main input line and neutral to
terminals L and N remain live at all times even
when the unit is switched off to ensure correct
operation of the unit and to let the fan operate
independent of the heating control. Never
incorporate controls that isolate the appliance
electrically.
The supply line to the heater should include a
mains switch / isolator adjacent to the appliance.
The minimum clearance distance between the
contacts must be more than 3 mm.
Check that the air heater is well earthed and
that an earth leakage test is carried out.
An external green indicator light is fitted on the
heater section to signify when the burner is ON.
An external burner reset switch with red
indicator light is fitted on the unit. To add a
remote reset button, make connections to the
terminals in the heater as indicated on the
wiring diagram.
If the reset button requires
activating for any reason, the
cause must be determined. After
determining and correcting the
problem, restart the heater and
monitor for a period long enough
to ensure proper operation
(approximately 5 minutes).
Ensure that all cables and installers wiring are
appropriately fixed and that they do not touch
the flue or combustion collector box.
To ensure that the unit is airtight, all unused
cable couplings must be hermetically sealed.
Permanent damage can occur
to the ignition controller when
faulty/incorrect connections to the
thermostat, reset switch or burner
failure lamp are made!
Switching of wires for reset switch
and flame failure will destroy the
ignition controller.
