Instruction Sheet

2
The Ducted Instant Heat 3-in-1 are ceiling mounted heat lamp appliances combining the functions of heater, extraction fan and luminaire.
Read through these instructions completely before commencing installation. Retain for future use.
This product shall be installed by a licensed electrical contractor or similarly qualified person.
CAUTION:
Regulations concerning the discharge of air must be fulfilled. Local building codes may require venting to the outside. 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 walls. Please note there is a danger of combustion if placed too close to curtains or other flammable materials. Under no
circumstances must the Instant Heat be covered with insulating material within the ceiling space.
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 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 the Wiring Rules conditions.
Note: Steam will only be removed if there is sufficient flow of air through the room. Ensure adequate inlet openings in the room are
provided, for example through windows, vents or under the door. Air-flow paths from room inlets to fan should ideally pass over
surfaces where condensation may form.

Remove all packaging from the product before commencing installation.
Ensure the circuit has been isolated from the 240 V mains before commencing work.
III. Locating the Instant Heat
Ensure the Instant Heat is installed at least 2.2 m above floor level.
IV. Preparation of the ceiling
Before cutting out the hole consider the orientation of the Instant heat
and the position of the duct outlet. To ensure maximum performance the
following points should be observed:
■minimise the number of bends in the ducting.
■level of the outlet grille should be at the level of the outlet duct.
■ducting should not be squashed.
■avoid sagging of the ducting to prevent water accumulation.
Using the ceiling cut-out template provided, mark the ceiling with a pencil
outline and cut out a hole at the chosen area. In the cut out made mark the
position of the duct holder (see template). Make sure the distance between
the edges and wall is not less than 300mm. Refer to Fig B.
V. Required Clearances
Within the ceiling cavity, there should be a minimum recess depth of
300mm to the roof. Thermal insulation or similar material shall not be
placed on top of the instant heat, and adjacent material shall be kept clear
to a minimum distance of 150mm. Joists, beams and rafters shall not be
cut or notched to install the Instant Heat. Refer to Fig C.
VI. In-house duct connection
Remove the duct holder from the Instant Heat and fit to end of ducting
with the cable tie. Clip the duct holder to the ceiling at the marked
position. Refer to Fig D.
VII. Remove the fascia
Remove all lamps from the unit. Remove the fascia.

VIII. Wiring
An Excel Life wall switch plate is provided with this product.
When choosing a location ensure the wall plate is not within
arm’s reach or accessible to a person in a bath or shower.
Follow the wiring diagram shown in Fig. E or Fig. F as applicable.
Once the wiring connection has been made to the Instant Heat, use a cable tie to fix
the cabling to the tie point to prevent contact with the hot metal housing. Refer to
Fig G.
IX. Insertion into cavity
Aligning the Instant Heat with the duct holder, carefully slide the unit into the cavity.
Ensure the guides in the Instant Heat body engage with the slots in the duct holder.
Ensure the 4 retractable clips do not catch in the hole cut-out. Refer to Fig H.
X. Once the unit is fully recessed, push out the clips and use a screwdriver to tighten.
Refer to Fig I.
XI. Final Installation
1. Replace the fascia and lamps. Fix the switch plate to the wall.
2. Reconnect power from the mains supply and test for correct operation.

I. Cutting a vent
Cut out a 150 mm diameter hole in the external wall or eave.
II. Ducting
The unit can be installed as shown below in Fig. 1. For best results the
outlet should be at the same level or lower than the exhaust fan (fig.1a &
fig.1b). Warning: Vertical ducting with roof vents will result in reduced fan
performance, increased noise and condensation/dripping (fig.1c). Mount
grille and seal any gaps around grille where necessary.
