8. Remove the inner front by removing the screws along its
top and sides. As the front insulation is attached care must be
taken when lifting this panel from the heater and placing it to
one side. Remove the internal packing by sliding it up and off
the elements taking care not to damage the insulation.

9.

9. Remove one element to allow access for the back rows of
bricks. On the 724N remove the element to the right of centre,
on the 718N remove the central element, on the 712N the left
hand element should be removed and, on the 706N, there is
only one element.
Loosen the two screws securing the element tails in the ceramic
connector block, and lift the element up and out of the heater.

10. Carefully fi t the bottom row of the back layer of bricks
placing the two end bricks in position fi rst with the recess
towards the element. Fit the top row of bricks also with the
recess towards the element.

11. Refi t the element which has been removed by feeding the
tails down through the hole in the base insulation and into the
connector block. Ensure the element is fully pushed home
then securely tighten the two screws in the block.

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.

CONTROL FUNCTIONS

THE INPUT CONTROL

For models WMS712N, 718N, 724N only:

This heater is fi tted with a user adjustable automatic input control
which varies the charge taken in response to weather conditions taking
into account the amount of energy already stored in the heater.
Set at 6 the heater takes maximum charge and at 1 the heater
takes a minimum charge at any room temperature. The casing of
the heater, particularly in late evening, may feel cool, this is quite
normal. The input control may require a few days experimentation
before your comfort level is established.
Initially set the control to 3, the following evening if the room is too warm
reduce to 2 or if it is too cool increase to 4. On subsequent evenings
adjust by half divisions until your comfort level is achieved.
Having established the setting the input will automatically carry the
amount of heat stored to compensate for weather variations.

CLEANING

To maintain the appearance of the heater wipe occasionally with a
dry cloth when the heater is cool.
Do not use abrasive powders of furniture polish.

AFTER SALES SERVICE

Issue 2

SETTING THE CONTROLS

The controls are located under the hinged fl ap at the top right hand
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. There are no user
adjustable controls on the WMX706N.

For models WMX712N, 718N, 724N only:

Initially set the input to 4. If the heater does not maintain a satisfactory
room temperature the following day this setting should be increased.
Conversely if the room temperature is too high this setting should
be reduced.
The input control should only require seasonal adjustments.

THE OUTPUT CONTROL

For all models except WMX706N

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 (or 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 a long
period, set the Output Control to 1. With the control in this position,
the heater will take less energy during the next charging up period.

Part No. 87570
