IMPORTANT SAFETY ADVICE
When using electrical heaters, basic precautions should always be followed to reduce
the risk of fire, electrical shock, and injury to persons, including the following:
IMPORTANT – The wall bracket supplied with the heater must be used.
IMPORTANT – All packaging should be disposed of in an appropriate manner.
OVERHEATING WARNING
WARNING - In order to avoid overheating, do not cover or obstruct the heater. Do
not place material or garments on the heater, or obstruct the air circulation around the
heater, for instance by curtains or furniture, as this could cause overheating and a fire
risk. NEVER cover or obstruct in any way the heat outlet slots at the top of the heater
or the air outlet slots in the base of the heater.
WARNING - THE SURFACES ON THIS HEATER CAN BE HOT.
The heater carries a warning ‘DO NOT COVER’ to alert the user to the risk of fire
that exists if the heater is accidentally covered.
CAUTION - Some parts of this product can become very hot and cause burns.
Particular attention has to be given where children and vulnerable people are present.
For your safety this heater is fitted with a thermal cut-out. In the event that the product
overheats for some reason, the cut-out prevents excessive temperatures on the product
by cutting the power to the heater. Once the heater has cooled down, it will reset
automatically, it will continue to cycle on and o automatically until the reason for
overheating is removed.
The display screen may flash red to indicate the product has overheated. To reset the
display, remove the obstruction and hold Enter for 10 seconds.

It is important to be aware of how your Quantum storage heater has been installed electrically. If you Quantum has
only one electrical connection, it must be carefully configured to work with your o-peak electricity tari.
Available fixed charge times must be manually programmed into the heater to tell it when to charge; no external
timers or contactors are needed. Up-to 4 digital charge times can be set.
If charge times are not programmed into the heater, the default times will be used which are set-up by default to
support dual-supply installations: 00:00 – 00:00 or 24h charge window.
A 24h charge window in a single supply installation will cause the heater to charge continuously,
including times when o-peak electricity is not available, resulting in larger bills.
Single Supply
NOTE:
If electricity tari charge times have changed, the digital charge times in the heaters settings must be
checked to ensure they match.

The controls are located on the top of the heater consisting of a display screen and three buttons and a Dial.
The heater is fitted with an adjustable thermostat enabling the room temperature to be controlled. The minimum room
temperature is 7°C. The maximum temperature is set to 30°C by default. A temperature of 21°C is a common comfortable
room temperature.
NOTE:
Your heater may produce some noise during operation. This noise
is caused by the low noise fan and expansion and contraction of
the metalwork as it changes temperature, and is normal for this
type of product. Whilst the noise produced is usually very quiet,
certain environmental factors can make it more noticeable, such
as hard flooring or minimal furnishings.
