Mounting
When mounted over a standard shop doorway the unit
should be fitted as low as possible and not more than
2.3 meters from ground level. A single unit will provide
reasonable coverage for a one metre doorway, and for
wider doorways units can be mounted end to end.
The unit should be positioned so that the airflow is not
obstructed by any part of the doorframe. When in-
stalled the top of the heater case should be a minimum
of 200mm from the ceiling.
Installation
Carefully unpack the unit and remove the top cover fix-
ing screws. The heater may be mounted using the
mounting bracket provided.
Loosen mounting screws, allowing the mounting bracket
to be removed from the unit. Making sure that the
mounting bracket is horizontal, fix the bracket to the wall
using 4 x No 8 wood screws. Place the unit on the mount-
ing bracket ensuring the washers are spaced as shown
on Fig 2 (a plain washer either side of the mounting
bracket).
Tighten screws to hold the unit at the required angle.
Spares
It is essential when ordering spares or replacement parts
to state the model number HE7433 and the serial number
on the rating place fixed to the top of the unit.
NB: DO NOT COVER ANY OF THE AIR INLET OR OUTLET
GRILLES AT ANY TIME.

The heater may also be mounted directly onto a suitable
wall or bearer by four No. 8 wood screws through the holes
provided in the back of the unit casing. Keyhole slots are
