Installation

5.1  Hydraulic connection

General notes

A separate interpretation of nominal flow rate

must be made for every system (see technical

data).

n

We recommend installing a buffer tank as a

hydraulic compensator for hydraulic isolation of

the heating/cooling circuit.
Hydraulic isolation is required when:
- different inlet temperatures are to be obtained
- the pressure drop in the heating distribution

system is greater than the max. pressure drop

stated in the technical data
- the use of other heat generators, e.g. com-

bustible burner for solid fuel, solar or bivalent

(dual-fuel) systems

n

Perform a pipe-network calculation before

installing the heat pump. After installing the

heat pump, it is necessary to perform a

hydraulic balancing of the heating circuit.

n

The heating/cooling system must be protected

against excessively high and low temperatures.

n

Do not reduce pipe diameters for the inlet and

return flow connections to the cooling module

before connecting a buffer tank.

n

Plan for air bleed valves and drain-off taps at

appropriate places.

n

Flush the system’s entire pipe network before

connecting the heat pump.

n

The heating/cooling system provided by the

customer must be protected to prevent the

temperature falling below the dew point (con-

densation water). The REMKO dew point mon-

itor with corresponding probes can be used for

this.

n

Cooling without a REMKO room temperature/

humidity probe is not permitted.

n

One or, where necessary, several expansion

vessels must be designed for the entire

hydraulic system.

n

The system pressure of the entire pipe network

is to be matched to the hydraulic system and

must be checked when the heat pump is

turned off. Also update the static-pressure form

supplied with the heat pump.

n

The dirt trap must be checked during every

maintenance of the system.

n

All exposed metallic surfaces must be addition-

ally insulated.

n

Cooling mode via the heating circuit requires a

complete vapour density insulation along the

entire length of the pipework.

n

All outgoing heating circuits are to be secured

against the ingress of circulating water by

means of check valves.

n

Before being placed in service, the system

must be thoroughly flushed. Conduct a seal

test and perform a thorough bleeding of both

the indoor unit and the entire system - repeat-

edly, if necessary, in acc. with DIN standards.
