1.5 Instructions for operating safety
1.5.1 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 success-
fully completed qualifying technical or vocational training and
who have taken part in advanced training sessions recog-
nised by the appropriate responsible authorities. 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 mains supply 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 Only original ROTEX replacement parts may be used.
1.5.2 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 them from the
power supply (switch off main switch, remove fuse) and
secure against unintentional restart.
Ɣ Equipment covers and service panels must be replaced as
soon as the work is completed.
1.5.3 Working on cooling systems (heat pump)
Working on the technical refrigeration system may only to be
carried out by people who are authorised and who have success-
fully completed a qualifying technical or skilled manual training
program for the particular work to be carried out and who have
participated in a professional development seminar held by the
appropriate responsible authority. 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 installa-
tions and heat pumps.
1.5.4 Corrosion protection
In a few regions, the water utility company supplies corrosive
domestic water, which can result in corrosion damage even if
high-quality stainless steel is used. Ask your water utility whether
the use of heating components made from stainless steel results
in problems with corrosion in your area.
Suitable water treatment may be required.
1.5.5 Operation
The ROTEX HPSU compact:
Ɣ Do not operate until all installation and connection work is
completed.
Ɣ Only operate with a completely full storage tank (Level
indicator) and heating circuit.
Ɣ Only connect with a pressure reducer on the external water
supply (supply line).
Ɣ Operate at a maximum pressure of 3 bar.
Ɣ Only operate the with the specified quantity of refrigerant and
the type of refrigerant specified.
Ɣ only operate if the protective cover is installed.
The specified servicing intervals should be adhered to and
inspection work must be carried out.
1.5.6 Documentation
The technical documentation included in the scope of supply is a
constituent part of the equipment. It must be stored in such a way
that it can be consulted at any time by the operator or the techni-
cians.
For work on stationary refrigeration systems (heat
pumps) and air conditioning systems, proof of expertise
is required in the European Community according to
the F-Gases Directive (EC) No. 842/2006.
– up to 3 kg coolant fill quantity: Stationary equip-
ment qualification category 2
