Please read carefully
Read through these instructions completely before commencing
installation.
CAUTION
This product is not designed to be ducted. Do not fit after-market ducting
kits. 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)
Installation:
The infrared lamps heat by direct radiation rather than by heating the air in
the room, so the Instant Heat should be located directly over the drying area.
HPM Instant Heat 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.
Air-flow path from inlets to fan should ideally pass over the steam sources.
Location:
The Instant Heat 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 300mm of
sides of walls, as per Figure 2. There is a
danger of combustion if placed too close to
curtains or other flammable materials.
Note: Instant Heat products must only be
installed horizontally in ceiling.
Ceiling preparation:
Instant Heat 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 Instant Heat and
adjacent building members shown in Figure 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 200mm (Fig.4).
Joists, beams and rafters shall not be cut or
notched to install Instant Heat.
After determining the location of Instant Heat
use this template to mark out and cut the
aperture (Fig 5). If adequate support is not
available for Instant Heat, it may be necessary to
provide extra strengthening.
Fixing to ceiling:
Remove all lamps to prevent damage from clip
fasteners. Spin the fan to check for freedom of rotation. Push the Instant
Heat body into the opening allowing the springs to snap open. To secure,
push the lower ends of the springs apart (Fig.6). Ceiling board thickness
should be adjusted to enable the springs to be fitted without excessive force.
Final assembly:
Check that the power to the unit is off. Position
the lamp surround below the unit so that the two
pins on the underside line up with the two holes
in the flange. The cover is designed to snap onto
the housing flange (Fig.7) which sits flush
against the ceiling.
Insert the five lamps into the sockets, tightening
well to ensure good electrical contact and long
life. Wipe the surround and the bulbs clean.
Connect the power and check all functions.
Wiring:
Four switches on an Excel Life wall plate are
supplied. Do not use with any solid state speed
control. Wall plate should be located so that the
switches are not within reach of a person in a
bath or a shower. Wiring connection is as per
Figure 8.
