ELECTRICAL CONNECTIONS
The heater is suitable for connection to a 415 volt 3 phase 50Hz supply.
With modification the unit can also be on a 240 volt 50Hz supply by
linking terminals L1, L2 and L3 on the main input terminal block and
connecting to the supply LIVE.
On full heat setting the load is 9 kW (CA1309S) & 12kW(CA1312S).
The connections between the unit and remote switch box are shown on
the rear of this instruction sheet, Fig 8.
FUSES
The motor and switch circuits are protected by two fuses which
have a 3 amp rating. Ensure that any replacement is of the correct size
and rating.
MAINTENANCE
ALWAYS ENSURE THAT THE MAIN EXTERNAL ELECTRICITY
SUPPLY IS SWITCHED OFF BEFORE SERVICING OF THIS
SCREEN-ZONE HEATER.
To obtain the best results from the heater it is essential to avoid the
accumulation of dust and dirt within the unit and on the inlet and
discharge grilles. Regular cleaning is necessary with particular
attention to the fronts and backs of the fan motor blades. Cleaning of
the fan is best carried out with a soft brush.
CONTROLS
The units are designed to provide 2 levels of heat ie half heat and
full heat, together with 2 fan speeds, normal and boost. The remote
control box houses 4 switches. The switch plate is marked as shown
below. The functions of the switches are as follows:-
SWITCH 1 (left-hand) ON/OFF
SWITCH 2 FAN SPEED CONTROL
SWITCH 3 ½ HEAT ON/OFF
SWITCH 4 ½ HEAT ON/OFF
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.
e) Fit the replacement switch, reconnect the wiring and replace the
cover.
For safety reasons a good earth connection must ALWAYS be made to the
unit and the control box. On the heater the earth terminal is adjacent to the
terminal block and is clearly marked with the symbol .
The unit should be wired in accordance with BS7671 latest edition
requirements for electrical installations. The installer should ensure that a
suitable fused isolating switch is connected in the mains supply.
THERMAL CUT-OUTS
There are 2 thermal cut-outs protecting the heater, positioned along
the heater box. These cut-outs are connected in series and each or both
may operate in the event of fan failure or restriction to the free flow of air
through the unit. The unit is protected by manual type cut-outs which may
only be reset by hand when the heater is switched OFF and has cooled
down. If the cut-outs trip, check the inlet and outlet grilles for airflow
restrictions.
TO RESET THE CUT-OUTS
a) The cut-outs are reset by switching OFF mains power to the
appliance and allowing the appliance to cool for 20 minutes.
b) Remove the appliance lid and locate the 2 cut-outs. Ensure mains
power is OFF. Reset each cut-out by pressing the white 5 mm
square reset button located on each cut-out.
c) Replace appliance lid. Switch ON the appliance. The cut-outs will be
reset. If the cut-outs trip again a qualified electrician should be
consulted.
SPARES
It is essential when ordering spares or replacement parts to state the
model number CA1309S or CA1312S and the serial number on the rating
place fixed to the top of the unit.
In the interest of progress the Company reserves the right to vary
specifications from time to time without notice. The material listed is
offered subject to the Company’s General Conditions of Sale, a copy of
which can be obtained on request.
MOUNTING
When mounted over a doorway, the unit should be mounted as low as
possible and not more than 3.4 metres above the floor. A single unit will
give adequate coverage for a 1.2 metre doorway. For wider doorways,
units may be mounted end to end. The heater should be mounted so that
the inlet or outlet air flow are not obstructed in any way. A clearance of at
least 300 mm should be maintained around the inlet and outlet grilles.
INSTALLATION
Having removed the appliance lid, to acquire these Instructions, also
ensure that the Remote Control Switch Box, which is packed inside the
appliance with these Instructions, is removed and retained.
The appliance ‘air flow’ and ‘external dimensions’ are shown in Fig 1.
The heater may be mounted in one of several ways ie:-
1. Wall Mounting
a. Using WALL BRACKETS supplied.
Onto a suitable vertical wall or bearers, the 2 wall brackets are
secured at the centres shown in Fig 2. The appliance, with 2 upper bolts
threaded securely into each face, is then fitted onto/between the wall
brackets as shown in Fig 3. The lower fixing bolts are then fitted through
each wall bracket into each side of the appliance.
The upper 2 bolts allow the appliance to be slipped onto, and held by,
the wall brackets. The fitting of the lower bolts in each side locks the
appliance to the brackets.
Tighten-up securely all 3 bolts in each side.
b. DIRECTLY to a suitable vertical wall or bearers.
Using 4 x No.12 wood screws. Screw through the holes in the
appliance case rear, at the centres shown in Fig 4. Keyhole slots are
provided for the upper 2 fixing screws, allowing the appliance to be initially
located. The lower 2 fixing screws pass through the appliance rear,
supporting the appliance and preventing any movement up off the upper 2
screws.
The wall surface to which the appliance is to be mounted must be flat
to avoid any distortion of the appliance casing.
2. Suspended/Hanging
a. Using Ø20mm CONDUIT.
The appliance may be suspended by Ø20mm conduit via two suitable
holes provided in the top of the appliance, see Fig 5.
b. Studding.
The heater offers four M8 threaded holes as shown in Fig 6. from
which the appliance may be suspended.
