General Instructions
Please read these instructions carefully before installation and
use, and keep them for future reference.
Application area
The FEZ336 has three heating panels and is designed for
mounting heights of between 4 and 12 metres.
FEZ336 can be used both for total or supplementary heating of
whole premises, and also for spot or zone heating of parts of
premises.
Operating conditions
The maximum surrounding temperature must not 30
°C.
Do not install where explosive vapours may be present, as
defined in BS 5345. Or in environments where there is an
increased risk of fire.
FEZ336 are protected to IP44, and are intended for indoor use
only.
Mounting
The FEZ336 can be mounted on the ceiling, on armature rails,
wire, or suspended from the ceiling by means of rods or chains.
The units are intended for permanent installation and should
always be mounted horizontally.
In rooms which are frequently used, the heater should be
mounted 1.5 to 2 metres above head height, see Fig. 2.
The distance between the heaters should be less than the
height between the heater and floor, i.e ”a” should be less than
”H”, see Fig. 2.
For minimum safety distances, see Fig. 3.
Mounting brackets are included and can be found inside the
connection box.
1) Determine the position of the panel on the ceiling.
2) Bend the "legs" of the brackets (fig 1.1) to approximately 90°
(fig1.2).
3) Mount the brackets with an internal distance according to
dimensional drawing page 2, on the ceiling or on a wire (fig
1.3).
When the panel is mounted on a wire put the bracket on top
of wire, and use clips to prevent the heater from sliding.
Mount the heater according to fig 1.4, start with one end
and then assemble the other one. Making sure that the
screws are tight.
Electrical installation
The F
EZ336 is designed for fixed installation.
The heater(s) should only be wired by a competent person and
in accordance with the current edition of the IEE Wiring
Regulations (BS 7671: Requirements for Electrical Installations)
and any applicable statutory regulations.
The appliance should be preceded by an isolating switch
preferably with a visual indicator.
The FEZ336 is approved for serial connection. Connection is
made via the block terminals (16 mm²) which are located at the
end of the heater.
There are are two holes for cable glands on the top of the
connection box. The cable glands used must guarantee the
protection class requirements.
Installations protected by a Residual Current Device (RCD)
If the installation is protected by a Residual Current Deive
(RCD) which trips when the heater is connected, this may be
due to a build up of moisture in the heating element.
This is easily rectified by connecting the heater without a RCD
so that the elements dry out. The drying time can vary from a
few hours to a few days.
As a preventative measure in very damp environments the
heater should occasionally be run for a short time during the
summer months
To prevent nuisance tripping of RCD's in large installations, the
heaters should divided over several circuits each with its own
RCD.
Maintenance
The heaters have no moving parts and regular maintenance is
not required.
There might be a rattling noise the first few weeks of use while
the heating panels settle, this is normal.
If the heater is used in rooms where aerosols, lacquer, solvents
or similar are present, the aluminium panels may discolour. The
output is not affected.
Important safety notices
Do not touch the surfaces of the heater while it is
operating, the surfaces are hot!
The heater must not be covered, as this will result in the
risk of fire.
The minimum safety distances (Fig 3) must be adhered to.
