Ensure the heater is at least 1000mm from any object. The heater can be tilted from 45° to 90° set it to the required angle b efore
switching the heater on. Adjust the heater angle by loosening the two bolts on the wall mounting bracket. Tighten the bolts a gain when
the desired angle is reached.
4.2
Ensure that the mains supply is adequately protected and that the mounting bracket is earthed, then switch on.

5.1
The heater contains no moving parts and therefore very little maintenance is required other than to ensure that there is no excessive
build-up of dust/dirt on the reflectors or emitters as this can cause overheating and premature emitter failure. To clean the appliance,
turn off and disconnect from mains supply, allow to cool then wipe with a damp cloth.
