3 THINGS TO BE CONSIDERED
Read through these instructions completely before commencing installation.
CAUTION:
This product is not designed to be ducted. If ducting is required then the ducted Instant Heat series,
R622D2 is more suitable for this purpose.
Regulations concerning the discharge of air have to be fulfilled. Local building codes may require
venting to the outside. The volume of the roof space must be a minimum of 3 cubic metres and
adequately ventilated to allow moisture to dissipate. This product is to be installed in standard roof
applications only, not in restricted ceiling cavities as found in multi storey applications (See Fig. 1).
To prevent heat accumulation, adjacent recessed bathroom heaters must be installed at least 2.0
metres apart from each other.

4 INSTALLATION
The infrared lamp heat by direct radiation rather than by heating the air in the room, so the
bathroom heater should be located directly over the drying area. Bathroom heater must not be
installed where there is a possibility of water splashing on to the lamps. Locate in accordance
with the requirements of the Australian/New Zealand Wiring Rules AS/NZS 3000 relating to damp
situations. This means that no part may be located directly above any part of the bath or shower
recess or enclosure. For unenclosed showers refer to Wiring Rules conditions.
Note: Steam will only be removed if there is sufficient flow of air through the room. Ensure
adequate inlets exist through windows, vents or under the door. Airflow path from inlets to
fan should ideally pass over the steam sources.
5 LOCATION
The bathroom heater is for ceiling mounting only, with the lowest point to be at least 2.2 metres
above floor level. It is not intended to be installed in wardrobes or within 300 mm of sides of walls,
as per Fig. 2. There is a danger of combustion if placed too close to curtains or other flammable
materials.
Fig: 1
Note: Bathroom heater products must only be installed horizontally in ceiling.
6 CEILING PREPARATION AND INSTALLATION
Bathroom heater may be installed either between joists using the built in clip fasteners or against
a joist using a screw to replace a clip. Drill a hole in the flange to suit. The clearances between
bathroom heater and adjacent building members shown in Fig . 3 shall be observed. Thermal
insulation or similar material shall not be placed on top of the unit, and adjacent material to the
side shall be kept clear to a minimum distance of 200 mm (Fig. 4). Joists, beams and rafters shall
not be cut or notched to install bathroom heater. After determining the location of bathroom heater
use cut-out template provided to mark out and cut the aperture (Fig. 5). If adequate support is not
available for the bathroom heater, it may be necessary to provide extra strengthening.
