After the transport, the transport securing device is to be re-
moved. (Valid only for the SI 21TE)
ATTENTION!
The transport securing device is to be removed prior to commissioning.

Set-up

6.1 General Information

The unit may only be installed indoors in rooms with low humidity
on a level, smooth and horizontal surface. The entire base of the
frame should lie directly on the floor to ensure a good soundproof
seal. If this is not the case, additional sound insulation measures
may be necessary.
The heat pump must be installed so that maintenance work can
be carried out without hindrance. This can be ensured by main-
taining a clearance of approx. 1 m in front of and on each side of
the heat pump.
Neither frost nor temperatures higher than 35°C must occur in
the installation location at any time of the year.

6.2 Acoustic Emissions

The heat pump operates silently due to efficient sound insulation.
To prevent noise transmission to the foundation, a suitable,
sound dampening rubber mat should be placed underneath the
base frame of the heat pump.
To prevent any sound from being transmitted to the heating sys-
tem, we recommend connecting the heat pump to the heating
system by means of hose sections.

Installation

7.1 General Information
The following connections need to be established on the heat
pump:
Flow and return flow of the brine system
Flow and return flow of the heating system
Power supply

7.2 Heating System Connection

ATTENTION!
Flush the heating system prior to connecting the heat pump.
Before connecting the heating water system to the heat pump,
the heating system must be flushed to remove any impurities,
residue from sealants, etc. Any accumulation of deposits in the
liquifier could cause the heat pump to completely break down.
Once the heating system has been installed, it must be filled, de-
aerated and pressure-tested.
The sensors which are delivered already connected and loosely
placed in the switch box must be mounted and insulated accord-
ing to the block diagram.
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. 5µm).
Scale formation in hot water heating systems cannot be com-
pletely avoided, but in systems with flow temperatures below
60°C the problem can be disregarded.
With medium and high-temperature heat pumps, temperatures
above 60°C can be reached.
The following standard values should therefore be adhered to
concerning the filling water and make-up water (according to VDI
2035 Sheet 1):

Minimum heating water 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 either
a dual differential pressureless manifold or an overflow valve.
The procedure for adjusting an overflow valve is described in the
Chapter Start-Up.
NOTE
The use of an overflow valve is only recommended for panel heating and
a max. heating water flow of 1.3 m³/h. System faults may result if this is
not observed.
