bedded water pipe:
- Connect the nipple joints (Fig 18/B)
to the cold water inlet pipe and the hot water
outlet pipe embedded in the wall at an
appropriate position and depth (please pay
attention to the distances shown in the dia-
gram).
- Screw the joints on the unit (Fig 18/A)
to the joints (both hot and cold water), using a
rubber leakage gasket (Fig 18/C) between
the joints.
Installing Water Heater wall-mounted
Connecting the water heater to a wall-mounted
water pipe:
- Connect the prepared water pipe to the
pre-assembled nipple joint.
- Screw the joints on the unit (Fig 19/A)
to the pipe (both hot and cold water), using a
rubber leakage gasket (Fig 16/B) between
the joints.
The cold water pipe must be turned
on in order to rinse it before
installation. Pressure-resistant equipment
must be used in compliance withaccepted
standards.
