4.4.4 Installation of the P connection kit
The optional P connection kit for B device types allows better
access for connecting the supply and return lines of a pressurised
solar system or another external heat generator on the storage
tank. The kit contains two thermally insulated corrugated pipes
that are connected to the connections of the storage tank via a
union nut. At the other end of the corrugated pipes there is an
adapter for different connection sizes of the supply and return
pipes.

WARNING!
Touching live parts can result in an electric
shock and lead to potentially fatal injuries and
burns.
● Before beginning work on live parts, discon-
nect all of the systems circuits from the
power supply (switch off external main
switch, disconnect fuse) and secure against
unintentional restart.
● The electrical connection and working on the
electrical components should only be per-
formed by electrical engineers in compli-
ance with valid standards and guidelines as
well as the specifications of the energy
supply company.
● The equipment covers and maintenance
opening covers must be re-fitted immedi-
on
ately after completion of the work.
CAUTION!
Increased temperatures may occur in the
Daikin Altherma M ECH
during operation. This can result in currently-
carrying wires from reaching higher tempera-
tures during operation due to self-heating. For
this reason, these lines need to have a contin-
uous use temperature of 90 °C.
● For the following connections, use only
cables with a long-term use temperature
≥ 90 °C:
