Thermostatic temperature control 

(Types HD 3346 and HD 3348 only)

Your fan heater is equipped with a thermostatic
temperature control (G). This control is used to
keep your room at a comfortable temperature by
sensing the temperature in the room and
switching the fan heater on and off automatically
to ensure this temperature is maintained.

To find the most comfortable setting:
-  Turn the fan heater on.
-  Turn the thermostat knob (G) clockwise to the

highest setting.

-  When the room temperature is comfortable,

turn the knob slowly anti-clockwise until the fan
heater switches off.

-  The fan heater will switch back on automatically

when the room temperature drops.

You can turn the thermostat knob while you are
using the fan heater.

Pilot light
-  When the appliance is plugged in and switched

on, the pilot light will come on.

-  The pilot light will stay on until the appliance is

switched off or unplugged.

-  The pilot light will stay on even when the

thermostat turns the fan heater off. 
This shows that the fan heater is still plugged in
and switched on.

Frost protection 

y

You can use the fan heater to keep frost away
from the area near the fan heater. For example, to 
prevent pipes freezing.
-  Put the fan heater close to the spot that you

want to keep frost-free.

-  Switch the fan heater on.

-  Set the thermostat knob to position 

y

(the

lowest thermostat setting, which is about 5°C).
The fan heater will switch off.

-  The fan heater will switch back on automatically

when the room temperature drops below 5°C.

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:
- (Types HD 3346 and HD 3348 only): First

ensure that it was not the thermostat which has
switched off the heater. Set the thermostat to
maximum position. If the heater still does not
switch on, you can be sure that the safety
device has been activated.

-  Remove the mains plug from the wall socket.
-  Let the heater cool down for 10 minutes.
-  Check that the heater has 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 your dealer.

Cleaning

-  Set the function selector (D) 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 enter into the
appliance.

-  Clean the air inlet and outlet openings regularly

(with normal use at least twice a year) with a
vacuum cleaner, using the brush attachment.
