4 Installer Important Information
Appliance location
Do not install the Climastat above another appliance that could damage it,
for example, above a cooker that might emit steam or grease or in a room,
which has a lot of dust in the atmosphere which is corrosive.
The Climastat must be installed in a room protected from freezing
temperatures. Take the necessary precautions.
Install the Climastat in such a manner so as to guarantee optimum
measurement of the ambient temperature by positioning it on an inside wall
in the main room of the house, approximately 1.5 metres from the ground.
Do not install the Climastat near heat sources such as radiators, televisions,
sunlight, on cold walls, between furniture, behind curtains, or other objects
that could effect measurement of ambient air temperature in the room.
Do not install close to draughts of air that could come from doors or
windows.
Explain these requirements to the home owner.
Safety instructions and regulations
This Climastat is tested and certicated for safety and performance. It is,
therefore, important that no alteration is made to the Climastat, without
permission, in writing, from Glow-worm.
Any alteration not approved by Glow-worm, could invalidate the certication,
appliance warranty and may also infringe the current issue of the statutory
requirements.
