1.0 SAFETY INFORMATION
•
The provision of the electrical supply and the connection of the NOXMASTER unit to the mains
must be carried out by a qualified electrician.
•
For installation and maintenance isolate from power supply before removing any covers.
•
All-pole disconnection from the mains as shown in the wiring diagram must be incorporated
within the fixed wiring and shall have a minimum contact separation of 3mm in accordance with
latest edition of the wiring regulations.
•
In order to avoid a hazard due to inadvertent resetting of the thermal cut-out, this appliance must
not be supplied through an external switching device, such as a timer, or connected to a circuit
that is regularly switched on and off by the utility.
•
The fan unit is supplied with a fused spur. The three core mains cable from the fan unit should
be connected to a fixed wiring installation, via the spur, in accordance with current IEE wiring
regulations.
•
If the mains supply cord to the PSU is damaged, it must be replaced by the manufacturer, its
service agent or similarly qualified persons in order to avoid a hazard.
•
The heater unit must be connected to the ceiling vent and fan unit using the 3 looms that
protrude from the heater module.
•
The unit must be situated in a dry environment that avoids dripping water and installed fully level
in the horizontal plane.
•
It is important to ensure that the diffuser is NOT placed within 1 metre of a smoke alarm. If the
diffuser cannot be repositioned, two sides of the diffuser must be closed off using the air dams
supplied to encourage the air through the remaining open sides that faces at least 1.5 metres of
unobstructed area away from the smoke alarm sensor.
•
If the unit is required to switch off in the event of smoke/CO detection, alarms are available with
separate relay bases from 3rd party companies. This is a mandatory requirement for all units
installed in a 3 Storey property.
•
The flexible duct (maximum length 2m) is connected to the base unit by inserting the duct over
the outlet duct and held in place using the supplied cable tie. Fix the duct in place by drilling
through the duct into the spigot (at the 2 O'clock and 10 O'clock position) and screwing together.
Finally secure the duct with a cable tie fitted between the screws and outlet face of the unit.
•
Ducting must be securely fixed with screws to the spigot to prevent access to live parts.
•
When installing the duct to the heater unit, insert the duct over the back of the heater, over the
protruding screw heads (3mm from the face of the duct) and fasten the cable tie below the screws.
This ensures that the duct will be held on securely, check all duct joints are air tight.
•
Appropriate PPE (Personal Protective Equipment) should be worn during maintenance. Precautions
may also be needed to protect the surrounding area from excess carbon residue.
•
Carbon filters/pellets are not to be ingested, ensure hands are thoroughly washed after handling.
•
Precautions must be taken to avoid the back-flow of gases into the room from the open flue of gas
or other fuel-burning appliances.
