ELECTRICAL CONNECTIONS
Mains power is fed into the remote switch control. The remote switch control is then connected to the appliance via the
Terminal Box. The switch splits the power feed to the appliance allowing ‘fan only – cold blow’ or ‘fan plus heater – hot
blow’ operation.
Note: AT ALL TIMES THE APPLIANCE AND REMOTE CONTROL SWITCH MUST BE EARTHED.

RETAIN THIS LEAFLET FOR FUTURE MAINTENANCE
This Claudgen Ceiling Heater is designed for suspension from a
ceiling using threaded bar. It is supplied with stud bar mounting
kit, painted enclosure and remote mounting control box.
ELECTRICAL CONNECTIONS
The HE7237 has a heating load of 3kW - 230/240V 50Hz
The HE7238 has a heating load of 3kW - 220V 50Hz
The connections to be made between the heater and the remote
control box are shown in Fig. 3. An earth terminal is adjacent to
the terminal block and is clearly marked with the symbol
The unit must be wired in accordance with I.E.E regulations for
the Electrical Equipment of Buildings and the installer should
ensure that a suitable isolating switch is connected in the mains
supply.
Fig. 2 shows wiring diagram.
CONTROL
The remote control box houses 2 double pole 20 amp rocker switches
and gives the following functions:
SWITCH 1 (LH)
OFF/FAN ONLY
SWITCH 2
FULL HEAT
MOUNTING
The fan heater box can only be fitted one way round (see Fig.1),
as 2 of the studs are offset. This ensures that the fan outlet
lines up with the discharge grille and also that the wiring is
always sited the same side.
The diffuser is attached to the discharge grille with 4 small
clips, which can be removed if necessary.
The discharge grille has 4 additional studs, plus nuts/washer, to
enable the unit to be chain mounted, if required.
There are also extra holes in the box to enable the unit to be
suspended via wires.
MAINTENANCE
ALWAYS ENSURE THAT THE MAIN EXTERNAL ELECTRICITY SUPPLY IS
SWITCHED OFF BEFORE SERVICING THIS HEATER.
To obtain the best results from the heater, it is essential to
avoid the accumulation of dust and dirt within the unit on the air
inlet and discharge grilles. Regular cleaning is necessary with
particular attention to the removal of any dirt on the fan rotor
blades. Cleaning of the fan is best carried out with a soft brush.
PROTECTION (Thermal Cut Out)
The unit is protected in the event of fan failure, or an
obstruction of the free airflow, by a thermal PTC Self Hold Cut
Out. Having tripped the PTC Cut Out remains open, effectively
switching off the heating elements, as long as mains power is
available inside the appliance. The PTC Cut Out will only reset
when the appliance is switched OFF and allowed to cool for at
least 20 minutes.
To reset the PTC Self Hold Cut Out
DO NOT ADJUST BY HAND ANY INTERNAL COMPONENTS
a)
The cutout is reset by switching OFF mains power to the
appliance.
b)
Allow the appliance to cool for 20 minutes
Re-start, switch ON the appliance. If the cutout trips again,
a qualified electrician should be consulted.
TO REPLACE A FAN/HEATER ASSEMBLY
a)
Switch off the mains supply
b)
Release the six nuts and washers fixing the fan heater box to
the discharge grille
c)
Disconnect the fan heater wiring from the mains terminal
block and earth stud
d)
Remove the fan heater from the box (four screws)
e)
Fit the replacement unit and re-assemble in the reverse
order.
TO REPLACE A SWITCH IN THE CONTROL BOX
a)
Switch off the mains supply
b)
Remove the switch box cover
c)
Disconnect the wiring to the switch
d)
Release the spring clips and push out the switch
