Serene S2067
Portable Fan Heater
Operation
The operation of the heater is controlled by the HI/LOW/OFF control knob and the adjustable thermostat
knobs located on the top of the heater. The blue LED indicator lights when the heater is operating.
Thermostat
The heat output is regulated by a built-in thermostat. The thermostat
maintains the required ambient temperature by automatically turning
the heat on and off as needed.
Starting from the lowest position, turn the thermostat knob
clockwise until you hear a ‘click’. The heater will then start heating and
the LED indicator will light up. The more the thermostat knob is turned
clockwise, the higher the ambient temperature will be.
If the ambient temperature is close to 35°C or more, the heater may not
turn on even if the thermostat is set on maximum. Alternatively, if the
ambient temperature is below 5°C, the heater may operate in ‘frost watch’mode
continuously even if the thermostat is set on minimum.
To set the thermostat:
1. Turn the thermostat knob clockwise to maximum
and wait until a comfortable ambient temperature is reached.
2. Turn the thermostat knob anti-clockwise until you
hear a ‘click’ and the heater turns off.
3. Fine adjustments can then be made.
Care
The heater requires regular cleaning to ensure trouble free operation.
Isolate the heater from the mains power supply.
Use a damp cloth to clean the exterior of the heater. Do not use any abrasive cleaners.
The S20667 is fitted with our new “Airslip” metal fan blade that alleviates any dust build up inside
the heater. Use a vacuum cleaner to remove any carpet fiber, dust and fluff visible on the heater
inlet and outlet grilles.
Ensure the heater is dry before turning the mains power supply to the heater back on.
