Note: SMOKE ALARMS -It is also 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.
3.2.2 Fitting Air Dams (if Required)
Air dams should be fitted where needed in order to alter the direction of
airflow. 2 air dams are supplied and will fit on any of the diffuser sides
to guide airflow away from a smoke detector and/or obstructions.

3.2.3 Fitting Ceiling Diffuser
To install the diffuser, use the tear-out template from the lid of the unit
packaging and trace the shape onto the ceiling between two convenient
joists. The shape is elliptical to allow space for the PCB of the controls
and this should be positioned for ease of access (i.e. NOT facing over
a stairwell). Once the shape has been cut out, position the ceiling vent
and secure it in place using the 4 screws and plugs provided. After
fitting, the fan unit must be connected to the diffuser using the loom
provided. The connectors are located on the rear of the ceiling vent and
the rear recess of the fan unit.
Finally attach the diffuser cap to the frame using the four built-in press
on clips provided.
3.3 Heater Installation
The heater unit must be connected to the ceiling vent and fan unit
using the 3 looms that protrude from the heater module. Connect
the ceiling vent control loom to the circuit board on the ceiling vent
and insert the heater module into the ceiling vent. Connect the
interconnect loom into the rear of the fan unit. Connect the mains
power loom into the power outlet on the underside of the fan unit.
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.
Finally 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.
IMPORTANT
Isolate from power supply before removing any covers.
During installation/maintenance ensure all covers are fitted
before switching on the mains supply.
IMPORTANT
CAUTION: 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.
3.0 MECHANICAL INSTALLATION
Successful operation of the fan depends entirely upon the unit being
installed strictly in accordance with these instructions. Please read
through this guide in its entirety before commencing installation and
follow step by step to ensure a satisfactory completion.
Whilst the installation of the unit may be achieved by suitable persons,
the provision of the electrical supply and the connection of the unit to
the mains must be carried out by a qualified electrician.
This appliance can be used by children aged from 8 years and above
and persons with reduced physical, sensory or mental capabilities or
lack of experience and knowledge if they have been given supervision
or instruction concerning use of the appliance in a safe way and
understand the hazards involved. Children shall not play with the
appliance. Cleaning and user maintenance shall not be made by
children without supervision.
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.
Means for disconnection must be incorporated in the fixed wiring as
shown in the wiring diagram in accordance with IEE wiring or national
wiring rules.
3.1 Loft Inspection
Check to ensure that the loft has adequate ventilation. There may be
occasions where a loft is so well sealed that additional ventilation may
have to be provided by the owner/occupier.
Ensure
that all water tanks are covered and sealed.
Check
that all water pipes are lagged.
Ensure
that any extract fans are discharging to outside and not into the
loft.
Check
that the loft hatch is tightly sealed.
Ensure
that all holes in the ceilings are sealed i.e. ceiling light fittings
etc. A visual inspection of any flues or chimneys for leakage in the loft
should be carried out by the installer.
If any
leakage points are found, or if there is any doubt at all, then the
installer should advise the house owner/provider as soon as possible
and seek instruction from them before proceeding with the installation.
3.2 Diffuser Installation
3.2.1 Positioning Diffuser
The diffuser has a unique air throw pattern and it is essential that it is
located correctly in the central hallway in single storey properties or in
the ceiling of the top floor landing on 2 or more storey dwellings.
The diffuser discharges air evenly in all directions along the underside of
the ceiling.
