2.4 Instructions for operating safety
2.4.1 Before working on the hydraulic system
Ɣ Work on the ROTEX HPSU compact (such as
setup, servicing, connection and initial start-
up) is only to be carried out by persons who
are authorised and who have successfully
completed qualifying technical or vocational
training and who have taken part in advanced
training sessions recognised by the appro-
priate responsible authorities for the specific
activity. This, in particular, includes heating
specialists and climate control technicians
who have experience, as a result of their
technical training and their knowledge of the
subject, of proper and appropriate installation
and maintenance of heating, climate control
and cooling installations and heat pumps.
Ɣ Switch off the external main switch before
starting any work on the ROTEX HPSU
compact and secure it against unintentional
switch-on.
Ɣ Seals must not be damaged or removed.
Ɣ Make sure that the safety valves comply with
the requirements of EN 12828 when
connecting on the heating side, and with the
requirements of EN 12897 when connecting
on the domestic water side.
Ɣ Only original ROTEX replacement parts may
be used.
Ɣ When working on the hydraulics, you must
first drain the water or release the pressure
using the internal KFE valve. Otherwise hot
water can jet out under pressure and result in
injury.
2.4.2 Electrical installation
Ɣ Electrical installation may be carried out only
by electrical engineers and in compliance with
the valid electro-technical guidelines as well
as the regulations of the relevant energy
supply company (EVU).
Ɣ Compare the mains voltage (~230 V, 50 Hz or
~400 V, 50 Hz) indicated on the type plate
with the supply voltage before connecting to
the mains.
Ɣ Before beginning work on live parts,
disconnect all of the systems circuits from the
power supply (switch off main switch,
disconnect fuse) and secure against uninten-
tional restart.
Ɣ Equipment covers and service panels must be
replaced as soon as the work is completed.
