3. MOUNTING INSTALLATION
3.1
CEILING MOUNTING
IMPORTANT!
Ensure that the ceiling is capable of taking the weight of the heater.
For optimum results do not fit in ceilings higher than 3m. Air is taken in through the large grille and discharged through the smaller grille. The air
intake and discharge areas must be kept completely clear for a minimum of 1.5m from the front of the heater. In an area using multiple units,
heaters should be spread to provide an even heat distribution.
Remove the front grille / cover by undoing the 8 screws securing it in place (You d
on’t need to remove this cover if using M6 drop rods or M6 hanging hooks.)
Using the drawing above mark out the holes required to secure the heater case to the ceiling. Use the 4 x keyhole slots and an additional 2 holes (at
least one each side) once installed to lock the heater in place.
These additional 2 holes MUST be used to stop the possibility of the case sliding off its Keyhole fixings.
Secure to the ceiling using suitable fixings (not supplied). It will be easier to do some of the electrical connections before finally securing to the ceiling.
3.2 DROP ROD MOUNTING
The heater has 4 x M6 threaded holes and 4 x M10 keyhole holes suitable for using M6 or M10 drop rod studding. If using M6 threaded holes fully
screw the studding into each hole and use a lock nut to stop it rotating and coming out. If using M10 studding a nut must be placed and tightened
above and below the case on each of the 4 studs to hold the case securely to the M10 drop rods (Removal of the grille / guard will be needed so
you can add an M10 Nut inside the heater). Use the diagram above to determine the spacing of the drop rods. If you use drop rods you should be
able to gain access to all the electrical connections after you mount the heater.
4. ELECTRICAL CONNECTIONS
4.1 230V SINGLE PHASE
– Without controls.
Please make sure you have read the Safety instructions and that you are a suitably qualified electrician before continuing.
Drawings show connections inside the black terminal box on the outside of the heater.
Do NOT use power tools to undo or do up terminal screws.
