Heating operation

Ensure the central heating system is ON.
Switch on the power supply to the unit. Set
the thermostat control (if fitted) to the desired
temperature. Providing the water temperature in
the central heating system is more than 38°C and
the thermostat (if fitted) is calling for heat the
product will switch on.
It is recommended that the model chosen is
capable of maintaining the calculated heat loss
at medium heat output enabling the high speed
setting to be used for faster heat up and the low
speed for maintaining temperature.

Maintenance

Warning! Isolate from the electrical supply
before performing any work on the unit.
The internal air filter is removable for servicing.
To gain access to the filter unlock and lower the
front access panel, remove the 2 screws from the
filter enclosure panel and lift out. Carefully lift out
and remove filter (see page 11). The filter should
be gently tapped to remove any accumulated
dust and vacuumed if necessary (approx. every
6 months). We recommend replacing the filters
approx. every 2 years depending on environmental
conditions.
The coil fins are delicate so take care and only use
a soft brush or vacuum cleaner to remove any dust
that may have accumulated.
The fan(s) and motors should not require servicing.
Please contact your supplier if damaged.
To replace filter use reverse the removal
instructions and ensure the lower front access
panel is securely locked.
Please note in the event of an engineer's visit,
Smith's Environmental Products Ltd reserve the
rights to apply a call-out charge should the fault
prove to be with the system or installation and not
the heater appliance.
