Thermostat knob (D)
With the thermostat knob you can set a constant
room temperature.
When the selector switch is set to position 1 or
position 2, the heater will automatically switch
on (using half power or full power respectively) as
soon as the room temperature falls below the set
temperature.
As soon as the set temperature is reached, the
heater will switch off.
Rotate the knob anti-clockwise to obtain a higher
temperature setting or clockwise for a lower
temperature setting.
You may adjust the thermostat during use.
To find the ideal thermostat setting:
- First set the knob to maximum position. (Rotate
anti-clockwise until the knob stops.)
- As soon as the temperature is comfortable, turn
the knob clockwise slowly until the heater goes
off.
y = "Frost-free" position. This position
corresponds with the minimum thermostat
setting (i.e. approx. +5 °C / +41 °F) and can
be used to keep the immediate vicinity of the
heater free from frost. E.g. to prevent pipes
from freezing, position the heater close to the
pipe and select this position.
Please note: When using the cool air setting >,
the thermostat knob should be in its highest
position .
Pilot light
- When the appliance is connected to the mains
and switched on by selecting >, 1 or 2 the
pilot light (E) will come on.
- The light will stay on until the appliance is
switched off by setting the selector switch (C) to
position O or by disconnecting from the mains.
- To indicate that the heater is still connected and
in "switched-on" position (>, 1 or 2), the pilot
light will remain on when the set temperature is
reached and the thermostat switches the
appliance off.
For the same reason the pilot light will remain
on when the overheating safety device switches
the appliance off.
Overheating safety device
To prevent damage and risks due to overheating,
the built-in overheating safety device cuts off the
power as soon as the heating elements become
too hot.
If this should happen:
- First ensure that it was not the thermostat which
has switched off the heater. Set the thermostat
to maximum position.
If the heater does not switch on, the safety device
has been activated.
- Remove the mains plug from the wall socket.
- Let the heater cool down for 30 minutes.
- Check if the heater had been placed correctly.
- Check if anything is obstructing the air flow.
If necessary, clean the grilles with a vacuum
cleaner.
- Replace the plug into the wall socket and switch
the heater on again.
If the safety device again switches off the heater:
- Remove the mains plug from the wall socket.
- Have the heater inspected by a Philips Service
Centre or by your dealer.
Cleaning
- Set the selector switch (C) to position O to
switch off.
- Remove the mains plug from the wall socket.
- Wait for the heater to cool down sufficiently.
- You may clean the outside of the heater with a
damp cloth. Do not allow water to come into the
appliance.
- Clean the air inlet and outlet grilles regularly
(with normal use at least twice a year) with a
vacuum cleaner, using the brush attachment.
