7 Mounting

7.1 General Information

The following connections need to be estab-lished on the heat

pump:

Flow and return of the brine (heat source system)

supply/return flow of the heating system

Temperature sensor

Voltage supply

7.2 Connection on Heating Side

ATTENTION!

The heating system must be flushed prior to connecting the heat pump.

Before completing the heat pump connections on the heating

water side, the heating installation must be flushed in order to re-

move any impurities that may be present, as well as residues of

sealing material, and the like. Any accumulation of deposits in

the condenser may result in a total failure of the heat pump.

Once the installation on the heating side has been completed,

the heating system must be filled, de-aerated and pressure-

tested.

Consideration must be given to the following when filling the sys-

tem:

Untreated filling water and make-up water must be of drink-

ing water quality (colourless, clear, free from sediments)

Filling water and make-up water must be pre-filtered (pore

size max. 5 µm).

Scale formation in domestic hot water heating systems cannot be

avoided, but in systems with flow temperatures below 60 °C, the

problem can be disregarded. With high-temperature heat pumps

and in particular with bivalent systems in the higher performance

range (heat pump + boiler combination), flow temperatures of

60 °C and more can be achieved. The following standard values

should therefore be adhered to with regard to the filling and

make-up water according to VDI 2035, sheet 1: The total hard-

ness values can be found in the table.

Fig. 7.1:Guideline values for filling and make-up water in accordance with

VDI 2035

For systems with an above-average specific system volume of

50 l/kW, VDI 2035 recommends using fully demineralized water

and a pH stabiliser to minimize the risk of corrosion in the heat

pump and the heating system.

ATTENTION!

With fully demineralized water, it is important to ensure that the minimum

permissible pH value of 7.5 (minimum permissible value for copper) is

complied with. Failure to comply with this value can result in the heat

pump being destroyed.

Heating water minimum flow rate

The minimum heating water flow rate through the heat pump

must be assured in all operating states of the heating sys-

tem. This can be accomplished, for example, by installing a dual

differential pressureless manifold.

Provided the heat pump manager and heating circulating pumps

are ready for operation, the frost protection feature of the heat

pump manager is active. If the heat pump is taken out of service

or in the event of a power failure, the system has to be drained.

In heat pump installations where a power failure cannot be read-

ily detected (holiday house), the heating circuit must contain a

suitable antifreeze product.

7.3 Connection on Heat Source

Side

The following procedure must be observed when making the

connection:

Connect the brine line to the flow and return pipe heat source of

the heat pump.

The hydraulic integration diagram must be adhered to.

ATTENTION!

The supplied strainer must be fitted in the heat source inlet of the heat

pump in order to protect the evaporator against the ingress of impurities.

In addition, a microbubble deaerator must be installed in the heat

source system.

The brine liquid must be produced prior to charging the system.

The brine concentration must be at least 25 %. Freeze protection

down to -14 °C can thus be ensured.

Only antifreeze products on the basis of mono-ethylene glycol or

propylene glycol may be used.

The heat source system must be vented (de-aerated) and

checked for leaks.

ATTENTION!

The brine solution must contain at least 25 % of an antifreeze agent on a

mono-ethylene glycol or propylene glycol basis and must be mixed prior

to filling.

NOTE

A suitable de-aerator (micro bubble air separator) must be installed in the

heat source circuit by the customer.

7.4 Temperature sensor

The following temperature sensors are already installed or must

be installed additionally:

External temperature sensor (R1) supplied (NTC-2)

Return temperature secondary circuit (R2) installed (NTC-

10)

Flow temperature secondary circuit (R9) installed (NTC-10)

Flow temperature primary circuit (R6) installed (NTC-10)
