INSTALLATION
Installation
Note
At least 40mm of the pipes must be accessible. If neces-
sary, remove any protruding foam insulation.
Push a straight push-fit connector onto each of the three
pipes.
5.2.1 Pushing the cylinder module towards the function
module
Push the cylinder module carefully towards the function
module, so that the rear r.h. adjustable foot of the cylinder
module is near the recess in the joining bracket.
5.3 Connecting modules
Removing the terminal bracket from the function module

1 Fixing screws on the terminal bracket
2 Fixing screws on transportation frame
Undo the fixing screws from the terminal bracket. Retain the
fixing screws; these are required later for the assembly.
Pull the terminal bracket out of the transportation frame.
!
Material losses
If resting the terminal bracket temporarily on the cover of
the function module, place something between the two
to prevent damage the paintwork.
Undo the fixing screws on the transportation frame and re-
move it. Retain the fixing screws; these are required later for
the assembly.
Cylinder temperature sensor and anode cable
Remove the cable tie that tie together the electrical cables
of the anode terminal and the cylinder temperature sensor
lead.
Pull the connecting cables/leads of the anode and the cylin-
der temperature sensor through the aperture located on the
top r.h. side in the cylinder module.

1 Aperture in the thermal insulation for sensor lead of the cyl-
inder temperature sensor
Push the cylinder temperature sensor from the top through
the aperture in the thermal insulation.
Insert the cylinder temperature sensor into the lower cylin-
der sensor well.
Note
It is possible that the cylinder module and the function
module will still be too far apart to be able to insert the
cylinder temperature sensor into the sensor sleeve.
If so, you can insert the cylinder temperature sensor into
the sleeve at a later point. What is important is that you
route the sensor lead through the insulation before you
install the terminal bracket.
The top sensor sleeve is required either in connection with buffer
operation on convector heaters (see chapter "Settings/ DHW/
DHW buffer mode") or for economy mode (see chapter "Connecting
internal cables").
