FIXING THE HEATER
The heater may be xed to the wall or oor using the xing holes provided in the mounting
frame. Please refer to the Section “Heater Dimensions and Minimum Operating Distances”
before xing the heater in position.
FIXING TO THE WALL
The heater must be xed only in the upright position with the control panel at the bottom.
The position of the two upper xing points should rst be marked on the wall, at a
horizontal distance of 100mm apart, Step 1. Place the heater in position with the upper
Suitable for xed mounting on the wall or oor, they can also be used free-standing in
a vertical or horizontal position. For maximum heating effectiveness the heater should
be positioned as low as possible within the area to be heated. Note: If the heater is to
be used unattended for long periods (e.g. in lofts) it should be permanently mounted in
accordance with the xing instructions given below.

wall bracket notches against these xing points to check that
the heater complies with the “minimum operating distances”.
These two xing points should then be drilled and plugged.
Suitable round headed size 8 screws should be xed in these
positions to such a depth that the heater may be hung in
position while the positions of the lower xing holes are
marked, Step 2. The heater should then be removed while the
lower xing holes are drilled and plugged. Then the heater
should be hung in position on the upper two screws while the
lower two screws are tightened to hold the heater rmly on
the wall. The tightness of the upper screws should be adjusted
if necessary to ensure a rm t.
FIXING TO THE FLOOR
The heater may be xed to the oor in the lay-at position. Before xing the heater in
position place it in the desired position and check that it complies with the requirements
described in the section “Heater Dimensions and Minimum Operating Distances”.
For guidance on xing the heater see the section on ‘Fixing to the Wall”. The principles
involved are the same.

User Controls
NEON INDICATOR
When your heater is plugged in and switched on at
the mains, the neon indicator will glow showing that
the heater is available for use, although the heating
element may not be energised, depending on the
setting on the thermostat knob.
THERMOSTAT
The thermostat knob is calibrated with a scale
marked ‘ ’ upto marked graphics. The lowest setting
‘’ is designed to switch on in a temperature range
of approximately 3°C to Minus 5°C and is suitable
for frost protection.
The other settings represent a range of temperatures dependent on a number of factors
including the size of the area to be heated and the outside temperature Actual settings
should be found by experience for each set of conditions.
The heater will not emit heat if the temperature of the air surrounding the heater is
above that set on the control knob, although the mains neon indicator will glow showing
that the heater is available for use. The heating element will energise if the thermostat
knob setting is increased, as indicated by an audible “click” when the thermostat knob
is turned.

THERMAL OVERLOAD CUT-OUT
The built-in overheat cut-out switches off the appliance automatically in the event of a
fault. Disconnect the electricity supply to the appliance. After a short cooling down phase,
the appliance is ready for use again. If the fault should occur again, follow the advice in
the “After Sales Service” section.
USING THE HEATER FOR FROST PROTECTION
The Heater may be used to protect water-tanks
(see Fig. 4), pipes and other frost-sensitive areas
by setting the thermostat to the Frost position.
When the thermostat is set at this position the
heater elements will emit heat only when the
temperature in the vicinity of the heater falls to
a temperature range of approximately 3°C to
Minus 5°C.
The heater will continue to emit heat until the
surrounding air again reaches approximately 50C
and will then switch off until the temperature falls
again. In this way, frost protection will be
provided in the area surrounding the heater. The Heater will also guard against frost in a
conned space such as a small greenhouse or unheated WC, provided the volume of the
space in which it is installed is appropriate to its heat output. Users must satisfy themselves
that the heat provided is adequate in all circumstances for the area to be protected.
Please be aware that frost protection is dependent on using the correct number of heaters
for the size of the area, its insulation levels and heat-loss conditions. More than one heater
may be required.
Important: The electricity supply to a
greenhouse should be installed by a
competent electrician in accordance
with the IEE wiring regulations. It is
recommended that residual current circuit
breaker (RCCB) protection is used.
The heat output of the Cold Watchers are similar to that of a small single burner
greenhouse parafn stove, however it has the advantage that they may be switched on
overnight as a precaution against frost with the knowledge that they will not consume
current on the frost setting unless the temperature in the vicinity of the heater falls below
approximately 3°C to Minus 5°C.
If only one heater is being used in a full size greenhouse, it will be necessary to partition
off that which requires frost protection, using for example heavy duty polythene sheeting,
which can also be used to line the glazing of the greenhouse to reduce heat losses and
therefore power consumption. As a guide to the effectiveness of a single Cold Watcher
in a greenhouse, it will raise the temperature of the shaded section of the greenhouse
by approximately 8 to 9°C.
USING THE HEATER IN A GREENHOUSE
IMPORTANT: Do not use this product
as a portable product in a greenhouse.
Securely x the product to a wall or oor,
as described in the installation section.
Operations

If higher temperatures are required then the volume partitioned off should be made
smaller. In this respect the only accurate method is to set the thermostat to a position
which keeps the temperature at the desired level by using a maximum/minimum
thermometer, positioned in the most critical part of the area to be heated. Although
the heater is designed to be splash-proof it is recommended that it be removed during
periods when spraying is being carried out in the greenhouse.
Floor Space
USING THE HEATER IN AN AIRING CUPBOARD
The heater is suitable for use in an airing cupboard
where there is no other heat source, or where the hot
water cylinder is so well insulated that insufcient heat
is available for airing clothes.
The airing cupboard should be ventilated by means
of vents for example in the upper and lower parts of
the door. This will allow circulation and removal of
moisture laden air. The heater should be positioned in
the lower part of the airing cupboard. It is important
that precautions are taken to prevent clothes from
falling onto the heater causing it to overheat. This
could take the form of a wire mesh positioned across
the lower part of the airing cupboard not less than
300mm above the heater. (Also refer to “Heater
Dimensions and Minimum Operating Distances”).
Clothing, bed linen or similar items must not be stored in this space if there is any
possibility of their falling on to or against the heater or coming within 150 mm of
the front or sides of the heater. A clear space of 300 mm must similarly be left above
the heater. If this space is to be used for storing such items, a further mesh should be
xed not less than 150mm from the front of the heater.
For electrical products sold within the European Community. At the end of the
electrical products useful life it should not be disposed of with household waste.
Please recycle where facilities exist. Check with a Local Authority or retailer for
recycling advice in your country.
Batteries should be disposed of or recycled in accordance with WEEE Directive
2012/19/EU. Packaging should be recycled where possible.
