NOTE:

Your appliance is equipped with an integrated electronic control system

so we cannot accept any liability should the appliance be used with pilot

wire programming base units that function by disconnecting the supply

voltage (refer to the instructions supplied with your control unit).

CONNECTING PRINCIPLE WITHOUT PILOT WIRE:

If the pilot wire is not connected, it must be insulated for safety reasons. Under

no circumstances must it be connected to earth.

3. Using your dual-energy towel

radiator

IMPORTANT This appliance has been designed to be

used either in central heating mode or electric mode.

Each application requires special, detailed procedures

to be followed. Inappropriate use may damage the resis-

tance as a result of excessive fluid temperatures, parti-

cularly in the event of simultaneous use in electric and

central heating modes.

Any inappropriate use will render the contractual gua-

rantee null and void.

3.1 Use as central heating

Ensure that the control unit is off.

The supply valve must be open to let water from the central heating system

circulate.

3.2 Use as electrical heating

A. When using the dual-energy, towel-drying radiator in "electric mode", close

the supply valve only and NEVER CLOSE THE HEATING UNIT'S OUTLET since this

enables the fluid to expand towards the installation.

CAUTION

Closing it may cause excessive pressure to build up with consequential

damage to the heating unit.

B. Ensure that the appliance is sufficiently full by opening the bleed tap at the

top. Close it again if there is a steady flow of water. A sponge and small container

should be used for this operation.

If the pressure is inadequate for bleeding the heating unit:

• fill the central heating system with water up to the level indicated on your

gauge,

• contact your heating specialist,

• inform the operating company (where heating is collective).
