3. MOUNTING INSTALLATION
3.1
CEILING MOUNTING
The heater is intended for installation in a suspended ceiling mounted within or on the 'tee' bar supports. For optimum results do not fit in ceilings
higher than 3m. As air is only introduced through the front of the unit the heater may be sighted anywhere. 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.
IMPORTANT!
A minimum clearance of 205mm is needed between the bottom of the false ceiling and the original roof/ceiling to allow
installation of the heater.
IMPORTANT!
DO NOT use plastic type diffusers as these may be damaged by the heat.
IMPORTANT!
Ensure that the mounting surface / ceiling supports are capable of taking the additional weight of the heater there are 2 eye
hooks supplied with the heater that should be used if additional support of the heater is required.
When using the diffuser the four Z brackets provided should be attached to the side of the heater to enable the heater to be supported by the 'tee'
bar and immediately above the diffuser.
