Dimplex WFE 3TNB Installation And Operating Instructions page 2

Procedure
Release the front cover from the unit by undoing the two screws under
the bottom edge.
Carefully remove cover by pulling bottom-front forward, and then lift to
release top from retaining slots.
Mark screw fixing positions on wall in accordance with the dimensions
shown on the diagram in Fig. 2. The unit must be secured to the wall
with four screws through the holes provided. The two upper holes are
keyhole shaped to enable the two upper screws to be positioned first.
The unit can then be hung on these screws while the two lower screws
are positioned. Before finally tightening all four screws, ensure the unit
is truly horizontal.
Fit a 3 core 1.5 square millimetre flexible cord through the cable entry
bush, connect wires to the appropriate terminals and tighten cable
clamp. Alternatively the heater may be connected with conduit through
the base after removing the knockout containing the cable entry bush -
see Fig. 3.

Operation
The WFE3TN has a total loading of 3KW. It
(d) (c)
incorporates a sensitive electronic thermostat,
and a programmable 7 day timer. To switch the
appliance ON, it should be connected to the
13 : 17
electricity supply and switched on at the ON/
OFF double pole switch – see 'b' in Fig. 4.
Thermostat (see 'a' in Fig. 4)
The thermostat scale is calibrated in 1°C
divisions with a temperature range from 5°C to
30°C.
To control the room temperature, set the mark
on the thermostat knob to the required
temperature on the scale. The electronic sensor
will monitor continuously the temperature of the
(a) (b)
air returning to the inlet grille, and the appropriate
Fig. 4
heater element(s) will be selected automatically
to achieve or maintain the chosen level. Two
pilot lights (see 'd' in Fig. 4) indicate when one
or both heating elements are in operation. An
additional pilot light on the digital timer will
illuminate when the timer is in 'Manual On' mode
or in 'Auto' mode with a program running. The
extra sensitivity of the electronic thermostat
ensures that the room temperature is maintained
Fig. 5 within close tolerances efficiently and
economically.
