Installation considerations

The unit must not be installed directly above a shower or bath. The unit must 

not be installed where water may splash onto the bulbs.

The unit must not be installed beneath a fixed socket.

The unit is designed for installation on flat ceilings only. Do not install on 

sloping ceiling or on a vertical wall.

The infrared heating bulbs are most effective when you are standing directly 

beneath them, install the unit above where you would stand to dry yourself. 

To obtain the best heating effect, we recommend there is between 2.3 and 2.7 

metres from the bulbs to the floor.

For the exhaust fan to work effectively, replacement air of a volume equivalent 

to what is being extracted must be able to enter the room. If the room is 

airtight, we suggest to leave a door or window open slightly to allow enough 

airflow.

Before commencing installation, check the ceiling space to ensure there are 

no obstructions such as ceiling joists, and that there is sufficient height 

clearance for the housing.

Installation

1.

Turn the power OFF.

2.

Locate a desired position on the ceiling, do not cut a hole yet.

3.

As the duct is only 3.0m, make sure that the distance from the centre of the 
installation position is not more than 3.0m from the exterior vent outlet. It is 
not recommended to use ducting longer than 3.0m as this will lower the 
performance of the exhaust fan. Check desired position suits duct length.

4. 

Locate a position for the exterior vent on the wall not more than 3.0m from 

the unit, and allows the ducting to remain straight. 

(Refer Fig. 1)

5.

Place this template against the ceiling and use it to mark the hole outline on 

the ceiling, ensuring there is minimum 250mm between the edges of the unit 

and any wall, and minimum cavity height of 250mm. Cut the hole for the unit. 

(Refer Fig. 2)

6.

Keep unit clear from insulation, use a barrier to keep loose-filled insulation 

material away from unit.

7.

Cut a 155mm diameter hole for the exterior vent outlet.

8.

Connect one end of the ducting to the exterior vent with the duct clips 

provided, and let the other end enter the room through the hole into the 

vent hole and seal the space around the hole.

9.

Remove all bulbs from the unit, unclip the internal fascia retaining springs 

inside the housing, unplug the LED at the connector and remove the fascia.

10.

Connect one end of the interconnecting cable wire with the switch panel.

Safety Considerations

Tri-Colour Downlight

The Infrared heating bulbs are most effective when you are standing directly 

beneath them, install the unit above where you would stand to dry yourself. 

To obtain the best heating effect, we recommend there is between 2.3 and 2.7 

metres from the bulbs to the floor.

For the exhaust fan to work effectively, replacement air of a volume equivalent 

to what is being extracted must be able to enter the room. If the room is 

airtight, we suggest to, leave a door ajar, increase the gap under an internal 

door (min 20mm) or add an return air vent into the lower section of the door. 

Note: Opening a window in cold weather conditions, may increase the incidence 

of steam production and is therefore not a preferred option.

Before commencing installation, check  the ceiling space to ensure there are no 

obstruction such as ceiling joists, and that there is sufficient height clearance for 

the housing.
