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)
Ɣ Always wear safety goggles and protective gloves.
Ɣ When working on the refrigerant circuit, ensure that the
workplace is well ventilated.
Ɣ Never carry out work on the refrigerant circuit in closed rooms
or work pits.
Ɣ Do not let refrigerant come into contact with open fire, embers
or hot objects.
Ɣ Never allow refrigerant to escape into the atmosphere (high
pressure at the point of the leak).
Ɣ When removing the service pipes from the filling connections,
never hold the connections in the direction of your body.
Residual refrigerant could escape.
Ɣ Components and spare parts must at least satisfy the
technical requirements defined by the manufacturer.
1.5.4 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.
1.5.5 Instructing the user/owner
Ɣ Before you hand over the ROTEX HPSU compact, explain to
the user/owner how to operate and check the system.
Ɣ Hand over the technical documentation (this document and
all supporting documents) to the user and advise him that
these documents must be made available at all times and be
stored in the immediate vicinity of the unit.
Ɣ Make a record of the handover by filling out and signing the
installation and instruction forms jointly with the user/owner.
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.
