Connection on heating side

• Refer to the } Device information [12, p. 37] for the relevant connection specifications.
• During installation, observe the trip pressure of the installed safety valve of 5.4 bar!
• When filling the heating circuit, pay attention to the frost protection valves.
The device is equipped with frost protection valves in the heating circuit. If the device is filled at outside
temperatures below 4 °C and there is no flow, it is possible the heating water is being drained through the frost
protection valves. Therefore, when filling the heating circuit make sure that the temperature and the heating water
flow are sufficiently high.
• After assembly on the heat pump, seal the empty conduits gas tight.
• After installation on the heating side, fill, purge and pressure test the heating system!

NOTICE
Damage due to leakage from hydraulic circuit
Leakage from the hydraulic circuit can result in damage due to escaping water.
▪ Ensure permanent sealing of the entire hydraulic network.
!
NOTICE
Damage due to impurities
If the heating system is not flushed, impurities, sealing material residue or similar can cause damage to the liquefier and
thus result in complete failure.
▪ Flush the heating system adequately before connecting the heat pump.
!
NOTICE
Damage due to incorrect distribution
Pump assemblies with check valves guarantee defined flow directions.
▪ If there is incorrect distribution or a fall in the volume flow, check these assemblies, particularly the check valves.
▪ With multiple heating circuits or parallel connection of heat pumps, fitting check valves is mandatory to prevent
incorrect distribution.
