Philips HD 3274/75 manual Thermostat knob D, Pilot light, Overheating safety device, Cleaning

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.
