Diffuser Overview
4.3 Fitting The 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 and
secure it in place using the 4 screws and plugs provided. After fitting
attach the diffuser cap to the frame using the four built-in press on clips
provided.
5.0 HEATER INSTALLATION
The heater unit must be electrically 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.
Push heater enclosure onto the back of the ceiling diffuser ensuring all
four clips engage.
Finally when installing the duct to the heater unit insert the duct over
the back of the heater, over the four protruding lugs and fasten the
cable tie below. This ensures that the duct will be held on securely,
check all duct joints are air tight.
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.
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.
3.1 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.
•
Check
any flues or chimneys for leakage in the loft via a visual
inspection, 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.
4.0 DIFFUSER INSTALLATION
4.1 Siting The 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.

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, the diffuser must be positioned
so as to encourage the air through the 2 open sides that face at least 1.5
metres of unobstructed area away from the smoke alarm sensor.
