6. THE FOLLOWING MUST BE APPLIED WHEN FIXING THE
HEATER TO THE WALL BRACKET
i) Ifnoskirting boardis present securethe heater throughthe wall
bracket slots closest to the wall.
ii) If 100mm (4in.) skirting is present secure the heater through
the outer slots.
iii) If skirting taller than 150mm (6in.) is present this must be
reduced to 150mm (6in.) over the entire width of the heater
plus 25mm (1in.) at each end.
Do not fully tighten these screws until the bricks are loaded into
the heater as some settling of the heater may occur.
NOTE: NEVER REMOVE THESE SCREWS WITHOUT FIRST
UNLOADING THE HEATER.

7. Remove the frontpanel by removing the twoself tapping screws
along its bottom edge. With hands positioned on each side of the
panel, lift upwards to unhook the top edge whilst pressing down on
the top panel with your thumbs.
Ensure the convector element is not damaged when placing this
panel to one side.

OPERATING INSTRUCTIONS
OPERATION
Your WMCS(N) heater combines the economy of a storage
heater with the convenience of a convector heater.
The storage heater takes in energy, when electricity tariffs
are low and dissipates it when tariffs are normal.
The convector heater provides an instant boost on
demand from normal tariff electricity.
SAFETY INSTRUCTIONS
1. Ventilate rooms well during commissioning.
2. Do not move the heater in any way once installed without the
services of a competent electrician.
3. Donotcover theheater withclothingetc. atany timeorposition
furniture close to or against the heater.
4. Ensure a clearance of at least 150mm between heaters and
curtains.
5. Should your heater fail to operate either employ the services
of a competent electrician or Telephone [phone].
ALSO REFER TO COVER PAGE
COMMISSIONING
Set both the Input Control and the Output Control to 6 and
leave the heater for 48 hours.
Following the commissioning period adjust the controls as
stated below.
SETTING THE CONTROLS
Thecontrolsare locatedunder the hingedflap at thetop righthand
corner of the heater.
To adjust the controls on the heater, use a coin and engage it in
the slots provided on the top surface of the knob.
CONTROL FUNCTIONS
THE OUTPUT CONTROL
Most of the stored heat is radiated from the casing during the
discharge period. However, some of the heat is emitted through
the grille at the top of the heater and this additional heat (boost)
is regulated by the Output Control.
With this set to 6 the boost begins in the early afternoon. Turning
the control towards 1 will progressively delay the commencement
of the boost. At 3 the boost will start in the evening. Once set, the
boost will repeat itself automatically day after day.
If no boost is required, e.g. when the room will be unoccupied
for along period, set the Output Control to 1. With the control in
this position, the heater will take in less energy during the next
charging up period.
CONVECTOR HEATER
CONVECTOR HEATER CONTROLS
The convector is selected
by an on/off rocker switch
which illuminates when
switched on ‘1’. With the
switch on, the convector
element shall be cycled
on and off by the room
thermostat. With the
switchoff“0”theconvector
will not run. The room
thermostat knob is marked 1 to 5. The higher the setting number
chosen, the higher the level at which the room temperature will
be controlled.
Your comfort level can easily be established by gradually
adjusting the thermostat until the required room temperature is
maintained.
CLEANING
To maintain the appearance of the heater wipe occasionally with
a dry cloth when the heater is cool.
Do not use abrasive powders or furniture polish.
Discoloration of wall finishes can sometimes occur immediately
above a storage heater due to the properties of some paints and
decorating materials or the presence of environmental impurities
in the air (such as soot or incense generated for the burning of
candles, etc.).
