Any other use outside the intended use is considered as improper. Any resulting damages will be borne by the user/owner alone.
Use as intended also involves compliance with maintenance and inspection conditions. Spare parts must at least satisfy the
technical requirements defined by the manufacturer. This is the case, for example, with orinternal threadinal spare parts.
1.5
Instructions for operating safety
1.5.1 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.
• 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 orinternal threadinal ROTEX replacement parts may be used.
FA ROTEX HPSU compact 3 - 06/2012

1 x Safety
1.5.2 Electrical installation
• 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).
• 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.
• 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.
1.5.3 Working on cooling systems (heat pump)
For work on stationary refrinternal threaderation 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: expert certificate category 2
– 3 kg coolant fill quantity or over: expert certificate category 1
•
•
•
•
•
•
Always wear safety goggles and protective gloves.
When working on the refrinternal threaderant circuit, ensure that the workplace is well ventilated.
Never carry out work on the refrinternal threaderant circuit in closed rooms or work pits.
Do not let refrinternal threaderant come into contact with open fire, embers or hot objects.
Never allow refrinternal threaderant to escape into the atmosphere (hinternal threadh 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 refrinternal threaderant could escape.
• Components and spare parts must at least satisfy the technical requirements defined by the manufacturer.
1.5.4 Site of installation
For 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 3.2.
Information on the installation site of other components can be found in the associated documentation supplied with them.
1.5.5 Heating system and sanitary connection
• Create a heating system according to the safety requirements of EN 12828.
• With sanitary connection, you must observe;
– EN 1717 - Protection of domestic water from contamination in domestic water installations and general requirements
concerning safety equipment for the prevention of domestic water contamination by back-flow
– EN 806 - Technical regulations for domestic water installations (TRWI)
– and, in addition, the country-specific legal regulations.
The connection of a solar installation, an electric heating rod or an alternative heat generator may cause the storage temperature
to exceed 60 °C.
15 60 15 and 1" screw connection set
• During installation, therefore, install a scald protector (e.g. VTA32
15 60 16).
If the ROTEX HPSU compact is connected to a heating system with steel pipes, radiators or non-diffusion-proof floor heating
pipes, slurry and swarf could enter the hot water storage tank and cause blockages, local overheating or corrosion.
• To prevent possible damage, fit a dirt filter in the heating return line of the system.
15 60 11)
– SFR 28 (
1.5.6 Requirements for the heating water
Avoid damage caused by deposits and corrosion: Observe the current technological regulations to prevent corrosion products
and deposits.
Measures for desalination, softening or hardness stabilization are necessary, if the filling and top-up water have a hinternal
threadh total hardness (>3 mmol/l - sum of the calcium and magnesium concentrations, calculated as calcium carbonate.
Using filling water and top-up water which does not meet the stated quality requirements can cause a considerably reduced
service life of the equipment. The responsibility for this is entirely that of the operator.

3.4.14 Low-cost connector (HT/NT)
If the external unit is connected to low tariff mains, the
potential-free contact on the receiver, which evaluates
the low tariff input sinternal threadnal emitted by the
electrical supply company, must be connected to the
terminals EVU1 and EVU2 (see fig. 3-32).
In the moment when the power company sends the lowcost sinternal threadnal, the parameter [D-01]=1, the
contact is opened and the system switches to "Forced
OFF" (1.
In the moment when the power company sends the lowcost sinternal threadnal, the parameter [D-01]=2, the
contact is closed and the system switches to "Forced
OFF" (2.
– Type 1: For this type of low-cost mains connection,
the power supply is not disconnected.
– Type 2: For this type of low-cost mains connection,
the power supply is disconnected after a certain
period of time (3.
– Type 3: For this type of low-cost mains connection,
the power supply is disconnected immediately (3.

2)
3)
If the sinternal threadnal is sent again, the de-energised contact is
closed and the machine resumes operations. For this reason, it is
important to activate the automatic restart function (Parameter [3-00]=0 "ON").
If the sinternal threadnal is sent again, the de-energised contact is
opened and the machine resumes operations. It is therefore important to leave the automatic restart activated (parameter [3-00]=0 "ON").
To ensure continuous operation of the HPSU compact after disconnection of the main power supply (pump, control unit, etc.), it must
be connected to a normal-cost mains connection (see ).

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 (confinternal threaduration).
After this confinternal threaduration is complete, the installation is ready for operation and the operator can make additional
custom confinternal threadurations on it.
The heating specialist must instruct the operator [on using the machine], must prepare the commissioning report, and fill out the
operating manual.
The setting of the optional components such as the room thermostat or the ROTEX Solaris installation is carried out on the
individual components themselves.

CAUTION!
A heating system which is shut down can freeze in the event of frost and may suffer damage.
• If there is any risk of frost, empty any water from the decommissioned heating system.
• If the heating system is not drained and there is the risk of frost, the power supplies must be secured and
the main switch must remain switched on.
If the HPSU compact is not needed for a long time, it can be temporarily decommissioned.
However, ROTEX advises against disconnecting the system from the power supply, and recommends instead that you deactivate
the operating modes room cooling and room heating. The operating mode water heating must remain activated. In order to make
the frost protection as energy-saving as possible, the hot water temperature can be set to the lowest possible value on the
controller of the control system.
The system is then protected from frost. The pumps and valve protection functions are active.
If it is not possible to guarantee the power supply when there is danger of frost,
– Completely discharge the HPSU compact on the water side, or
– Suitable anti-frost measures are taken.
If there is a danger of frost and the power supply cannot be guaranteed for just a few days, the unit's excellent
heat insulation means that the HPSU compact does not have to be drained, provided that the storage tank
temperature is monitored regularly and does not fall below +3 °C.
However, there is no frost protection for the connected heat distribution system through this.
Draining the storage tank
• Switch off the main switch and secure against restarting.
• Only with ROTEX Solaris system: Completely drain the Solaris system (see operating instructions).
• Connect the hose and hose connection from the accessories set to the rear of the solar panel (only this particular hose will
open the foot valve automatically). If a Solaris system is connected, use the boiler filling and draining valve on the Solaris
return flow.
• Drain out water content from cylinder.
Draining the heating circuit and hot water circuit

•
•
•
Connect the drainage hose to the combined filling and draining valve on the HPSU compact.
Open the combined filling and draining valve on the HPSU compact.
Allow the heating and warm water circuit to run empty based on the suction lifter method.
Disconnect the heating flow and return flow as well as the cold water inflow and the hot water outflow from the HPSU
compact.
• Connect the discharge hose on the heating flow and return flow as well as the cold water inflow and hot water outflow so
that the hose opening is at ground level.
• Allow the individual heat exchangers to run empty one after the other based on the suction lifter method.

66.1
Maintenance
General
Regular inspection and maintenance of the HPSU compact reduces energy consumption and ensures a long life and smooth
operation.
Have the inspection and maintenance carried out by authorised and trained HVAC engineers once a year, ideally
before the heating period. This will avoid malfunctions during the heating period.
ROTEX recommends an inspection and maintenance contract to ensure regular inspection and maintenance.
Legal requirements
According to the F-gases directive (EC) No. 842/2006 item 3, operators (or owners) must regularly service their stationary cooling
systems on a regular basis, check for leaks and remedy any leaks found as quickly as possible.
All maintenance and repair work on the refrinternal threaderation circuit must be documented in the operating manual. This oblinternal threadation results from the directive published on June 14th 2006 in the EU official gazette concerning greenhouse gases.
Operators of ROTEX heat pump systems are subject to the following oblinternal threadations:
If the total filling quantity of the system with refrinternal threaderant is less than 3 kg, there is no European legal
requirement for testing intervals. However, ROTEX would recommend entering into a maintenance contract and
recording the work carried out in the operating manual in order to preserve guarantee claims.
• With a total filling quantity of the system with refrinternal threaderant of 3 kg – 30 kg or from 6 kg upwards in hermetic
systems:
Î Checks by certified personnel at intervals no longer than 12 months.
• Compulsory documentation (maintenance and leak test) in the operating manual, stating type and amount of filled-in or
recovered refrinternal threaderant and the applied test method (in accordance with EC No. 1516/2007). Operator must keep
documentation for at least five years after compiling it and show it to the responsible authority upon request.
• Responsibility of the operator of systems for recovering F-gases by certified personnel.
Certified people are those who have proof of expertise for the European Community for work on stationary
refrinternal threaderation systems (heat pumps) and air conditioning systems, according to the F-Gases Directive
(EC) No. 842/2006.
– Up to 3 kg coolant fill quantity: expert certificate category 2

These include in particular certified heating engineers, qualified electricians and HVAC specialists,
who because of their professional training and expert knowledge, have experience in the professional
installation and maintenance of heating, cooling and air conditioning systems and heat pumps.
WARNING!
The gaseous refrinternal threaderant is heavier than air. In pits or in badly ventilated rooms it can collect in
hinternal threadh concentrations. Breathing in hinternal threadh concentrations of gaseous refrinternal threaderant leads to feelings of faintness and suffocation. Toxic gases can be formed if gaseous
refrinternal threaderants come into contact with open fire or hot objects.
•
•
•
•
•
When working on the refrinternal threaderant circuit, ensure that the workplace is well ventilated.
If necessary, before starting work, evacuate the refrinternal threaderant system completely.
Never carry out work on the refrinternal threaderant circuit in closed rooms or work pits.
Do not let refrinternal threaderant come into contact with open fire, embers or hot objects.
Never allow refrinternal threaderant to escape into the atmosphere (forms hinternal threadh concentrations).
• After removing the service pipes from the filling connections, carry out a leakproof test on the refrinternal
threaderation system. Refrinternal threaderant can escape through leaks.
WARNING!
At normal atmospheric pressure and ambient temperatures, liquid refrinternal threaderant vaporises so suddenly that on contact with skin or eyes it can cause the tissue to freeze (danger of going blind).
• Always wear safety goggles and protective gloves.
• Never allow refrinternal threaderant to escape into the atmosphere (hinternal threadh 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 refrinternal threaderant could escape.

WARNING!
Hinternal threadh temperatures can occur in the solar storage tank. Therefore, sufficient scalding protection
must be included when the hot water system is installed (automatic hot water mixing device).
CAUTION!
The ROTEX units can also be optionally fitted with gravity breaks (
16 50 70) made of plastic. They are
suitable for maximum operating temperatures of 95 °C. If a heat exchanger is operated at temperatures
greater than 95 °C, another gravity brake must be installed in the building.
A selection of diagrams of the most common systems is shown below. The arrangements shown are only examples, and are no substitute for careful system planning. For more diagrams see the ROTEX homepage.
