Permissible combinations of ROTEX external units for heat pumps and the ROTEX HPSU compact
Any other use outside the intended use is considered as improper. The operator alone shall bear responsibility for any resulting
damage.
Use as intended also involves compliance with maintenance and inspection conditions. Replacement parts must at least satisfy
the technical requirements defined by the manufacturer. This is the case, for example, with original spare parts.

Instructions for operating safety
Before working on the
hydraulic system
• 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 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.
• Switch off the mains supply before starting any work on the ROTEX HPSU compact and secure it against unintentional
switch-on.
• Lead tamper-proof seals must not be damaged or removed.
• 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.
• Only original ROTEX replacement parts may be used.
Electrical installation
• Electrical installation may be carried out only by electrical engineers and in compliance with the valid electrotechnical guide-
lines as well as the regulations of the relevant energy supply company (EVU).
• Compare the mains voltage (~230 V, 50 Hz) indicated on the nameplate with the supply voltage before connecting to the
mains.
• Before beginning work on live parts, disconnect them from the power supply (switch off main switch, remove fuse) and
secure against unintentional restart.
• Equipment covers and service panels must be replaced as soon as the work is completed.
Working on cooling systems (Heat pump)
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.
– total overall coolant weight up to 3 kg: expert certificate category 2
– total overall coolant weight in excess of 3 kg: expert certificate category 1
• Always wear safety goggles and protective gloves.
• When working on the refrigerant circuit, ensure that the workplace is well ventilated.
• Never carry out work on the refrigerant circuit in closed rooms or work pits.
• Do not let refrigerant come into contact with open fire, embers or hot objects.
• Never allow refrigerant to escape into the atmosphere (high pressure at the point of the leak).
• When removing the service pipes from the filling connections, never hold the connections in the direction of your body.
Residual refrigerant could escape.
• Components and spare parts must at least satisfy the technical requirements defined by the manufacturer.
