6.2 Install the hydraulic connections
ATTENTION
Damage to the copper pipes due to unacceptable
loading!
►
Secure all connections against twisting.
The heat source system has been installed
in accordance with the specifications
(
planning & design manual, dimensioned
diagrams, installation plans).
Cross-sections and lengths of the pipes for the
heating circuit and heat source are dimensioned
adequately.
The free pressure of the circulation pumps
produces at least the minimum throughput
required for the unit type (
“Technical data/
Scope of supply” on page 22).
The cables for the heat source and the heating
are fixed to the wall or ceiling via a fixed point.
Connect the unit to the heat source and
heating circuit
1. Install shut-off devices at the connections of the
heat source and heating circuit.
2. Insert the vent at the highest point of the heat
source and the heating circuit.
3.
Recommendation: Fit a dirt filter with mesh size
0.9 mm onto the heat source inlet.
4.
Ensure that the operating overpressures
(
“Technical data/Scope of supply” on page
22) are not exceeded.
6.3 Connect the electrical cables
ATTENTION
Irreparable damage to the compressor due to
wrong rotating field!
► Ensure that there is a clockwise rotating field for
the compressor load infeed.
Basic information on the electrical connection
●
The specifications of the local power supply
company may apply to electrical connections.
●
Fit the power supply for the heat pump with an
all-pole miniature circuit-breaker with at least
3 mm contact spacing (IEC 60947-2).
●
Note the level of the tripping current
(
“Technical data/Scope of supply” on page
22).
●
Comply with the electromagnetic compatibility
regulations (EMC regulations).
–
Lay the control/sensor cables and unit supply
cable sufficiently far apart (> 100 mm).
–
Lay unshielded power supply cables and
shielded cables (LIN bus cable) with sufficient
distance between them.
●
Do not lengthen the patch cable and LIN bus
cable. LIN bus cables up to 30 m long can be
used if the quality of the cable is the same as
that of the original cable.
