Electrical installation

Electrical installation may only be carried out by authorized personnel.

The connection cables must be laid in such a way that they do not come

in contact with hot components of the unit/burner or with sharp edges.

The electrical installation must comply with national regulations.

It is advisable to run the incoming supply through an on-board fuse or

automatic circuit breaker. The power cable must be laid in such a way

that it does not come in contact with hot components of the unit/burner

or with sharp edges.

Changes at the internal electrical installation or the connection of other

electrical components (e.g. external fan) to the internal wiring of the

appliance will expire any claims from guarantee and product liability!

Power line connection

The power must be supplied via a properly earthed socket outlet or hard-

wired connection.

Where a socket outlet is used for the mains connection lead, the outlet

must be freely accessible.

It is advisable to run the incoming supply through an on-board fuse or automatic

circuit breaker.

The power cable must be laid in such a way that it does not come in contact with hot

components of the unit/burner or with sharp edges.

If the connection cable is damaged it must be replaced by the Customer

Service at Dometic, or by respectively authorized personnel, in order to

prevent any hazards.

Battery connection

The machine's mains 12V connection cable is connected (observing correct

polarity) to a terminal strip. The cabling must be direct and by the shortest possible

route to the battery and alternator respectively.

The 12V circuit must be protected with a 20A fuse.

The heating element circuit must be connected to the vehicle battery by a suitable

ignition operated relay in order that the 12V supply is only live while the vehicle

ignition is switched on. The connection C/D (interior light, electronics ; cable black /

violet) must be permanently attached, and must not be cut-out when the vehicle

ignition key is turned off. This can be realised with an on-board habitation battery i.e.

This 12V permanently connection must be protected with a 2A fuse!

If the appliance is installed in a caravan the respective leads for 12V+

and 12V- the connections A/B and C/D must not be connected to each

other on the caravan-side)
