Any other use outside the above-mentioned use is considered as improper. Responsibility for any resulting damage will be borne by the user/owner alone.

Intended use also includes the observance of 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.

1.5 Instructions for operating safety

Before working on the hot water heating system and cold water cooling 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 technicians 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 installations may only be carried out by qualified electrical technicians under observance of the relevant electrical

guidelines and the regulations of the electric utilities company (EVU).• Compare the mains voltage (~230 V, 50 Hz or ~400 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)

• 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.

Corrosion protectionIn some regions, corrosive drinking water is supplied by public utility companies that can cause damage through corrosion even in high grade stainless steels. 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.

Equipment installation locationFor safe and fault-free operation, it is necessary that the installation location of the HPSU compact fulfils certain criteria. Related information can be found in chapter 2.

Information on the installation site of other components can be found in the associated documentation supplied with them.

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

1 x Safety


Hydraulics• Create a heating system according to the safety requirements of EN 12828.• For the connection on the heater side, the safety valves must meet the requirements of EN 12828 and must be type-approved.

When a solar energy facility is connected, the temperature of the tank must not exceed 60 °C.• When installing the system, you should therefore fit a scald protection unit (e. g. VTA32, 15 60 15).When using a HPSU heat pump system in a bivalent construction or with solar heating support, a shut-off due to excess pressure may arise due to an excess return temperature on the HPSU.

• To prevent heat spikes, install a return line temperature limiter in the installation.– RLB 300, 14 01 14– RLB 500, 14 01 15

Sanitary connectionWith sanitary connection, you must observe;

• EN 1717 - Protection of drinking water from contamination in drinking water installations and general require-ments for safety equipment for prevention of drinking water contamination by back-flow,

• EN 806 - Technical regulations for drinking water installations (TRWI),• and, in addition, the country-specific legal stipulations.

OperationThe ROTEX HPSU compact:• Do not operate until all installation and connection work is completed.• Only operate with a completely full storage tank (Level indicator) and heating circuit.• Only connect with pressure reducers on the external water supply line.• Operate at a maximum pressure of 3 bar.• Only operate with the specified quantity of refrigerant and the type of refrigerant specified.• Only operate when the cover has been assembled.

The prescribed maintenance intervals must be maintained and the inspection work must be carried out.

Instruct the owner• Before you hand over the ROTEX HPSU compact, explain to the user/owner how to operate and check the system.• Document the handover by filling out the installation and instruction forms together with the owner and sign them.

Installation without room thermostat:The cable bridge- mounted on-site - is recommended by ROTEX as otherwise problems may arise due to the cyclical circulation pump during heating operation. The DIP switch 3 (see Tab. 3-1, Chapter 3 "Start-up") must be set to "ON".

The absence of a summer switch-off on the circulation pump can be compensated for by manually switching off heating in the summer (key ) when a cable bridge is mounted.

Fig. 2-19 Connection without room thermostat*

* The cable bridge must be installed on-site before start-up.

2.5 Laying refrigerant lines

2.6 Pressure test and vacuum

• Perform pressure test with Nitrogen.– Use Nitrogen 4.0 or higher.– Maximum 40 bar.

• After leak search is complete, completely drain.• Vacuum lines.

– Pressure to be reached 1 mbar absolute.– Time: minimum 1 h.

• Check whether additional refrigerant is needed for primer filling, fill where necessary.• Open stop valve on exterior unit completely until the stop. Tighten loosely.• Reassemble valve caps.• Check whether storage tank sensor is 80 cm deep.• For bivalent installations or in connection with the ROTEX Solaris installation: �

Check whether a return line temperature limiter (RLB) was installed.

• Check whether oil raise arc necessary.– Required when HPSU compact not installed on same level as external unit.– An oil raise arc must be installed for every 10 m of height difference �

(Image 2-26, H = distance from one oil raise arc to another).– Oil raise arc only required in the gas line.

• Install lines with bending unit and an adequate clearance to electrical lines.

• Only solder with light nitrogen flow (hard soldering only).• Do not apply insulation to joins until after start-up (for purposes of

leakage search).• Establish flange connections and connect to the units.

The RLB is designed to mix the flow when the heating return line exceeds 55 °C. If the return line temperature continues to rise, the RLB will shut off the heating return line completely and the heat pump runs along a short circuit between the flow and return flow.

The RLB is needed in all installations in which the return flow can exceed 55 °C (Solar, second heat generator,...).

3 x Start-up


3 Start-up3.1 Initial start-up

After the ROTEX HPSU compact was installed and connected completely, it will need to be undergo a one-time adaptation to the installation environment to be carried out by technical personnel (Configuration).

After this configuration is complete, the installation is ready for operation and the operator can make additional custom configurations on it.

Setting up optional components such as a room thermostat or the ROTEX Solaris installation is carried out on the particular component.

3.1.1 Requirements

– The ROTEX HPSU compact is fully connected.– The heating and hot water system are filled and charged with the right pressure.– The storage tank is filled to the overflow point.– The heating system's control valves are open.– The refrigerant system is dehumidified and filled with the specified amount of refrigerant.– All electrical connections have been made in accordance with the Installation chapter.– Optional accessories have been mounted on and connected up.

3.1.2 Configuration of DIP switches

Tab. 3-1 DIP Switch Settings (* = factory setting)

WARNING!

To make changes to the DIP switch settings, the installation must first be disconnected from the power supply.

� Non compliance may cause damage to the HPSU compact.

• Check the DIP switch setting on the A1P circuit board of the HPSU compact, adjust where necessary (see Tab. 3-1).

3 x Start-up


3.1.3 Test run and setting of minimum flow

• Set pump level 3 of circulation pump of HPSU compact (Image 2-2, Pos. 6).• Start the system by pressing the key on the main control unit (HPR1).• Wait for the start phase.

� The number "88" is displayed for approx. 30 s during the start phase on the display of the main control unit (HPR1).

� The system starts an automatic test run that lasts approx. 30 min.�During this test run, nothing particular is shown on the Display.

� After a successful automatic test run, the system starts normal operation.

• Check minimum flow when heating circuit closed and bypass valve configured:– Minimum flow 6-8 kW HPSU compact (Image 4-3): >12 l/min– Minimum flow 11-16 kW HPSU compact (Image 4-4): >15 l/min

It is important that the water temperature does not fall below 10 °C during the test run. Otherwise the frost protection switch could be activated and the test run would not be completed.

Only when backup-heater (BUH) is installed:If the water temperature falls below 10 °C, the key must be repeatedly pressed until the symbol is displayed. This switches on the backup-heater (BUH) during the automatic test run and the water temperatures is kept above 10 °C.

If the installation has already been put into operation, the test run can also be started manually.

• Start the system by pressing the key on the main control unit (HPR1).• Press the key 4x in succession (also refer to the instruction manual).
