CHOOSING A PROPER LOCATION

HOW TO CHOOSE A PROPER LOCATION FOR HEATER

This product can be installed in places that require direct radiant heating and circulated air flow such as bathrooms, ensuites and laundries.

Consideration on safety

1. Do not install the product directly above shower cubicle or bath enclosure.
2. Do not install the product in a location where there is a possibility of water will splashing onto the lamps or the switches being touched by a person in the bath or shower.

Consideration on ventilation

1. It is very important that air is allowed to enter the room being ventilated. This can be done by increasing gap under the door, installing door grilles or opening windows. It is impossible to exhaust more air from a room than is allowed to enter it.
2. The product should be positioned to ensure ventilation air traversing the room provides ventilation to all areas. Avoid positioning the product too close to windows or doors as such positioning cut short the airflow path and does not provide proper ventilation. Ensure air is ventilated to outside through ductwork. Precaution must be taken to avoid the back-flow of gases into the room from the open flue of gas or other fuel-burning appliances.

Consideration on orientation

1. The product must be horizontally mounted on a ceiling and not on a wall or a raked ceiling.
2. It is recommended that the air outlet points towards an outer wall and the ductworks interconnecting the air outlet and the external grille are laid in a straight fashion. If it is desirable for ductworks to run across any timber structures such as rafter, stud or joist, ensure the closest structure is not within 300mm of the air outlet.

Consideration on clearances

1. Ensure the air outlet of the product is not directed to or close to a rafter or stud allowing draft stopper on the outlet to fully open when fan is turned on.
2. Ensure at least 2.1 meters between the product fascia and the floor.
3. Ensure at least 235 mm clearance above the ceiling for installation.
4. Ensure at least 50 mm between the sides of the heater and any building element adjacent to it.
5. Ensure at least 1.0 meter between the sides of the heater and the sides of any adjacent heater, as well as at least 1.0 meter away from combustible objects such as curtains.
6. Do not cut or notch joists, studs, beams and rafters to install the product.
7. Before installation, ensure that there is no hidden electrical wiring or utility behind the spot where the opening is going to be made. Check and plan for the wiring route carefully.
8. Ensure the ceiling is strong enough to support the weight of at least 10 kg.

CHOOSING A PROPER LOCATION

RECOMMENDATION ON DUCTING INSTALLATION

1. Plan the required length of duct carefully; cutting off excessive length of duct and ensuring ducting is as short as possible.
2. Ensure ducting is fully extended, properly supported, straight and not slacking.
3. Ensure ducting is not obstructed or squeezed.
4. Avoid bending the duct.
5. Do not use ducting with a diameter smaller than the diameter of the outlet, or the collar of the grille to which the duct is connected.
6. Secure ducting connection properly using clamp, cable tie or tape.

INSTALLATION INSTRUCTIONS

Important Safety Note: Make sure electricity is turned off at the main power box before commencing work. Turn off the power by removing fuse or turning off circuit breaker before installing the product and replacing lamp.

Ceiling Support Note: Make sure that ceiling joists are strong enough and of adequate size to support the weight of at least 35 kg.

Step 1: Choose Mounting Location

Take time choosing an appropriate mounting location and direction with reference to instructions in the previous page. Make sure all clearances required around the product are observed and there is no obstructing structure nearby the outlet. The area behind the intended location must be clear of obstacles such as cables, utility pipes and joists.

Diagram Description: A diagram illustrating the chosen ceiling location, showing the product outline, required clearances, and the area behind the ceiling needing to be clear of obstructions.

INSTALLING GRILLE ON WALL

Step 2: Mark and Cut Grille Opening

Mark out a circle of the base diameter at the desired location. Using an appropriate cutting device, cut along the line and remove excess material from the marked location.

Diagram Description: A diagram showing a wall grille base and louver, with a circle being marked on a wall for cutting.

Step 3: Install Grille and Ductwork

Remove the louver from the base of the grille, noting the four screw holes on the base. Push a duct through the hole and connect it to the collar of the base. Secure the ducting connection with the clamp provided. Then fix the base at the desired spot using four suitable screws (not provided). Install the louver onto the base. Install ductwork following the recommendation on ducting installation in the previous page, and direct the duct towards the general direction of the cut out and air outlet on the product.

INSTALLING BATHROOM HEATER

Step 4: Trace Cut-out Template

Use a pencil and trace around the template supplied with the package.

Diagram Description: Hands are shown tracing a template onto a ceiling.

Step 5: Cut Ceiling Opening

Using an appropriate cutting device, cut along the line and remove excess material from the ceiling. If necessary, provide additional support to the ceiling.

Tips: Do not cut the hole any larger than the specified cut out dimension.

Diagram Description: A diagram showing a cut-out hole in the ceiling, with arrows indicating required clearances (MIN 50mm, MIN 300mm, MIN 290mm) and the direction of the outlet.

Step 6: Remove Fascia

Remove fascia from the main unit with care by pressing the two spring levers attached to the rear of the fascia and disconnect the lamp wire.

Diagram Description: A diagram showing the main unit with the fascia being removed by pressing spring levers, and the lamp wire being disconnected.

Step 7: Access Terminal Block

Remove wiring box cover to access the terminal block by loosening four screws. Check the air outlet and remove any adhesive tape holding the draft stopper in place to allow free movement in operation.

Diagram Description: A diagram showing the main unit with the wiring box cover removed, exposing the terminal block. The air outlet with a draft stopper is also visible.

Step 8: Remove Draft Stopper Tape

Remove the sticky tape on the draft stopper.

Diagram Description: A diagram showing the draft stopper inside the air outlet with sticky tape being removed.

Step 9: Insert Unit and Connect Ducting

Draw wires out from the cut-out hole and make wiring connection in accordance to the wiring diagram provided. The product must be earthed during installation. Connect ducting to the outlet and secure its connection. Insert heater into the cut-out hole at an angle ensuring the duct connection is intact and no cable or insulating material rests over or against the heater. Make sure side clamps are pulled inwards so that the rest of the housing can pass through the hole without damaging plaster board.

Tips: Do not overtighten clamp when securing ducting to the air outlet to allow the draft stopper to fully open in operation.

Diagram Description: A diagram showing the heater unit being inserted into the ceiling cut-out, with ducting connected and side clamps being used to secure it.

Step 10: Secure Unit in Ceiling

Ensure the unit is held securely in place by pushing the side clips outwards and tighten the screws until the main unit rests flush to the ceiling.
