OPERATING INSTRUCTIONS
OPERATION
Your CSH(A) 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. Do not cover the heater with clothing etc. at any time or position
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 contact your supplier.

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
The storage controls are located on the top panel. The
convector controls are located at the top of the front panel’s
right side.
CONTROL FUNCTIONS
THE INPUT CONTROL
For models CSH12A, CSH18A and CSH24A 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 4, the following evening if the room is too warm
reduce to 3 or if it is too cool increase to 5. On subsequent evenings
adjust by half divisions until our comfort level is achieved.
Having established the setting the input will automatically carry the
amount of heat stored to compensate for weather variations.
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 switch off “0” the convector 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 fi nishes 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.).

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.
