punched out. Any other holes that are not going to be used must be

sealed watertight.

Inserting the connecting cable (Fig. D)

• Push the grommet 11 over the end of the connecting cable.

Note: Do not use the grommet for a cable with a cross-section

of 16 mm

• Place the heater over the connecting cable.

• Press the grommet into the hole in the rear wall of the heater through

which the cable should be fed. Ensure that the edges of the grommet

are flush with the hole all the way round.

of the heater.

• Connect the water outlet and inlet and tighten the securing nut on

the mounting bolt.

Checking for leaks and flushing the heater:
