GENERAL

This product is designed to maintain defrosting condition and is not capable of reaching

and maintaining human thermal comfort. It is therefore out of scope of the Ecodesign

Directive for local space heaters.

Both models can be controlled by there variable thermostat which has a minimum setting

suitable for frost protection. They are specially designed for use where localised heating

is needed, or where a small heater is only necessary for general heating or a level of

frost protection. These heaters are versatile and robust units ideal for greenhouses, lofts,

garages, utility rooms, sheds, chalets, spare rooms, conservatories, airing cupboards,

outside WCs, kiosks, checkouts etc.

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.

Installation

A. Horizontal mounting, fixed or portable:

Minimum horizontal distances from sides

and end of heater to obstruction. Minimum

distances from top of heater to shelf or

overhanging obstructions.

B. Wall mounting: Minimum vertical distance

from top of heater to shelf or overhanging

obstruction. Minimum horizontal distance

from front of heater to obstruction.

C. Upright portable operation: Minimum

vertical distance from top of heater to

shelf or overhanging obstruction. Minimum

horizontal distance from front of heater to

obstruction.

D. Wall mounting or portable: Minimum

distance to sidewall or obstruction.

Note 1 - For maximum heating effectiveness

the heater should be positioned at a low level.

Note2 - It is recommended that the heater is

not tted into an unventilated enclosure which

is less than 10 cubic feet.

IMPORTANT - If wall mounted the heater

should be mounted only in the upright position

with the control panel at the bottom.

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.
