2. The heater must not be installed beneath a fixed socket.

3. The unit is designed for installation in flat ceilings only. Don’t mount it on a sloping ceiling or a vertical wall.

4.The infrared lamps are most effective when you are standing directly beneath them, so generally the unit would be mounted a place where you would stand to dry yourself.

5. For the exhaust fan to work efficiently, replacement air of a volume equivalent to what is being extracted must be able to enter the room. In general this air would be drawn under the door, or through a slightly
open window. If the room is airtight, the fan will function poorly.

6. Before commencing any cutting, check in the ceiling space that there are no obstructions such as ceiling joists and that there is sufficient height clearance for the housing. Check that the electrical wiring can be routed from the wall switches to the mounting location.

1. Cutting a vent (when required)
For installation where external venting is required or is your choice, locate a suitable location in either the roof or exterior wall to vent out the exhausted air / steam and cut out a 105mm hole.

2. Ducting
Put one end of the 100mm diameter ventiduct into the vent hole and seal space around the hole using a suitable sealant and cowling where necessary.

Note: Since the length of each duct is 1.5m, make sure that from the center of installation position there should be a distance within 1.5m to the outside vent.

3. Locating the heater
For the purpose of obtaining best heating effect, from the lamps there should be about a 2.3m overall height to the ground.

Using this instruction card as a template, mark the
ceiling with a pencil outline and cut out a hole in the
ceiling at the chosen area.

Make sure a distance between the edges and wall is no less than 250mm. Also from the rooftop there should be a minimum 220mm height to the ceiling.

Ensure that the intended hole will have suitable room to
locate the unit and will not foul on joists or not fit in the
headroom provided.

and fix the end with duct clip.
