Install the safety assembly (acces-

sory or on-site provision) in accord-

ance with DIN 1988 in the cold water

line (see page 10).

Recommendation:

Install the safety valve above the

DHW cylinder to protect it against

contamination, scaling and high tem-

peratures.

Connect the drain hose to conden-

sate collector L. Remove plug from

condensate collector.

3. Route condensate hose M to the

back (drain in wall G) or to the side

aperture H (see page 6).

Route condensate hose with a U-

bend and connect to on-site drain line

or siphon.

4. Prepare the gas connection accord-

ing to TRGI or TRF or all local regu-

lations.

5. Prepare the electrical connections.

■Power cable: NYM-J 3 x 1.5 mm2,

fuse max. 16 A, 230 V/50 Hz.

■ Accessory cables: NYM with the

required number of conductors for

the external connections.

■Allow all cables in area "K" (see

page 7) to protrude 2000 mm from

the wall.
