KFF13T
Do not site the unit close to soft fabrics, which could be sucked over the intake grill,
blocking airflow into the unit causing it to then overheat. Allow an air gap of at least 600mm
to the front and rear of the unit to ensure a clear airflow.
To Start
Connect to a suitable electrical supply.
The unit cannot operate without the fan switch in the ‘1’ position.
1 – Switch the fan rocker switch to ‘1’.
2 – Switch the heater rocker switch to ‘1’.
3 – Set the thermostat to the desired temperature.
Maximum total ducting length is 7.5m with 8”duct. Do not exceed, to run further lengths
contact manufacturer. Keep ducting as taut and as straight as possible, avoiding kinks and
sharp bends. Do not restrict the ducting outlet with grills.
To stop
Set the heat rocker switch to ‘0’, fan only and leave the unit in the fan only mode for 5
minutes MINIMUM to allow the elements to cool.
Once the unit’s heat has been dissipated, turn the fan rocker switch to ‘0’ and disconnect
from the electrical supply.
It is now safe to move the unit.
Failure to observe these instructions could result in damage to the elements.
The KFF13 is fitted with a safety limit thermostat. Should the designed operating temperature
be exceeded, it will open circuit the elements. These will automatically reset as the
temperature reduces.
Maximum ambient working temperature is 40°C.
In areas where several heaters are used simultaneously the positioning of the units is an
important consideration.
Optional Thermostat if fitted.
Rotating the control knob fully clockwise will cause the heater to keep providing heat until
the ambient temperature sensed by its sensor (the copper tube located inside the rear grill)
reaches nominally 40º C.
At this point, power to the heating element will be interrupted, leaving the fan running only.
If the control knob is turned anti-clockwise then the user is looking to lower the sensed
ambient temperature at which the element switches off.
When the sensed ambient temperature is below the point at which the thermostat is set to,
power is once again applied to the element.
