6 Installation

6.1General Information

As a rule, the unit must be installed indoors on a level, smooth and horizontal surface. The entire base frame should make full contact with the surface in order to ensure adequate sound insu- lation. Failing this, additional sound insulation measures may be- come necessary.

The heat pump should be installed to allow easy maintenance/ service access. This is ensured if a clearance of approx. 1 m in front of the heat pump is maintained.

P

Heating water minimum flow rate

The heating water minimum flow rate through the heat pump must be assured in all operating states of the heating system. This can be accomplished, for example, by installing a differential pressure-free manifold or an overflow valve. The procedure for setting an overflow valve is described in the Chapter Commis- sioning.

Frost protection for installations prone to frost

Provided the controller and heating circulating pumps are ready for operation, the frost protection feature of the controller is ac- tive. 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 instal- lations where a power failure cannot be readily detected (holiday house), the heating circuit must contain a suitable antifreeze product.

6.2Sound Emissions

The heat pump offers silent operation due to efficient sound insu- lation. Any vibration transmission to the foundation or the heating system can be largely prevented by internal sound decoupling measures.

7 Mounting

7.1General Information

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

„supply/return flow of the brine system

„supply/return flow of the heating system

„power supply

7.2Connection 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.

7.3Connection on Heat Source

Side

The following procedure must be observed when making the connection:

Connect the brine line to the flow and return pipe of the heat pump.

The hydraulic plumbing diagram must be observed here.

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.

7.4Electrical Connection

The following electrical connections must be established on the heat pump:

„Connection of the control wire to terminals X1: L/N/PE in the control box of the heat pump.

„Connection of the load wire to terminals X5: L1/L2/L3/PE in the control box of the heat pump.

„Connection of the brine pump (to be supplied by the cus- tomer) to terminal PE and pump contactor K5: 2/4/6 on the control panel of the HP.

All electrical components required for the operation of the heat pump are located in the control box.
