Technical Illustrations
The technical illustrations show the assembly of the
"fresh water module 33". These graphics apply equally
to other available fresh water modules from ETA.
Assembly and installation only by qualified
specialist personnel
The assembly and installation may be performed
by specialist personnel with the corresponding
qualifications only.
4.1 Preparation
Select installation site of the fresh water module
The fresh water module can be attached to a wall or
directly on the buffer storage tank. If installing on a
wall, the fresh water module should be mounted in the
vicinity of the buffer (maximum 5 m simple line length)
to limit pressure losses.
The length of the CAN-Bus line supplied for
connection to the boiler is 10 m. The
3 temperature sensors for the buffer can be connected
to the circuit board [EM-C] of the fresh water module.
Removing the plastic cover
Prior to starting installation, remove the plastic cover
by loosening the screw on the bottom side.
Hydraulic connection on the buffer
Ideally, the fresh water module is laterally connected to
the buffer. Since this ensures optimal ventilation of the
buffer on its buffer cap.
Fig. 4-1: preferred connection variant
If a lateral connection is not possible, the fresh water
module can be connected to the buffer cap. But then
the flow line must have an incline to the fresh water
module. The T-piece for the bleed valve must be the
same size as the connection on the buffer, so that no
air pocket may form.
