Before Installing
PLEASE NOTE: Must be installed by a licensed electrician.
A few minutes planning can make a big dierence to the installation time and also to your satisfaction
with the function of your bathroom heat lamp.
• Before commencing any cutting, check in the ceiling space that there are no obstructions such
as ceiling joists (at least 50mm clearance) and that there is sucient height clearance (at least
220mm) from the unit. Check if the electrical wiring can be routed from the wall switches to the
mounting location.
• This bathroom heat lamp must be installed at least 2.1m above the oor. Ceiling height cannot
exceed 2.85m.
• This heater is to be installed so that switches and other controls cannot be touched by a person in
the bathtub or shower.
• Ceiling insulation should be kept well clear away from the unit and all ducting equipment.
• The unit should not be installed directly above a shower or bathtub.
• The unit must not be installed where it will be subject to direct splashing.
• Your bathroom heat lamp is designed for installation in at ceilings only. Don’t mount on a sloping
ceiling or a vertical wall.
• The infrared lamps are not designed to heat the entire room area; they provide instant heat to
persons standing directly below them. Install your bathroom heat lamp above the area where
‘drying o’ usually occurs.
• Your bathroom heat lamp has not been designed for extended periods of operation, as this could
cause overheating and premature failure.
• For the exhaust fan to work eciently, air ow of a volume equivalent to what is being extracted
must be able to enter the room.
• In general, air would be drawn under the door, or through a slightly open window. If the room is
airtight, the fan will function poorly.
• The distance between the sides of the heater and the sides of any adjacent ceiling recessed heater
shall not be less than 200mm
Installation
• Please read these instructions carefully before installing and using the product. Keep the instruc-
tions handy for future reference.
• Electrical wiring must only be done by a licensed electrician and a “Certicate of Compliance” must
be issued upon completion of the installation.
LOCATION
• The unit must be located and installed in accordance with AS/NZS 3000 and local building codes
and regulations concerning the discharge of air have to be fullled.
• The unit can be installed in any room that requires direct radiant heating and circulated air
ow such as bathrooms, ensuites, laundries etc. The unit can be installed in at ceilings with a
minimum height of 2.1 metres. At least 250mm height clearance in the ceiling cavity is required
to ensure sucient ventilation for moisture to disperse. The unit must also be installed at least
400mm away from the walls.
• Ensure adequate inlets exist through windows, vents or under the door for airow.

circuit if loading permits. All electrical work must be carried out in accordance with AS/NZS 3000 or
latest edition thereof.
MOUNTING
1. The unit may be mounted either between joists using the inbuilt clip fasteners or against a joist
using a screw through the ange plate. Use this card in its open state as a template. Place in the
required location and mark out the hole cutting size. Hole size is 310 x 300mm.
2. Before commencing cutting ensure that the area behind the intended location is clear of all cables,
pipes and joists. Once clear, cut out the section along the previously marked lines.
3. Remove 2 heat lamps from the bathroom heater, then remove the plug of the LED downlight inside
the housing. Unfasten the fascia. Connect the ducting if required to the outer grill of the unit. Insert
the unit into the square hole being sure to pull the side springs inward so that the body can pass
through the hole without damaging the plaster. Ensure that the unit is held securely in place by the
clips. If required, additional screws can be used to aid holding the unit in the ceiling. Screw holes are
provided in the ange for this purpose.
4. Connect the LED downlight plugs rst. Hold the fascia against the body of the heater and the ceiling
and attach the securing spring clips to hold the fascia in place.
5. Now screw in the two large heat lamps into the lamp holder through the holes provided in the
fascia. The globes should be screwed up rmly to ensure a good electrical contact but don’t over
tighten.
