10 Start up

NOTE! Read the safety instructions!
⚠ The installation may only be commissioned if the heating
system, water heater and brine system have been filled and
bled. Otherwise the circulation pumps may be damaged.
⚠ If the installation is only to be run on auxiliary heating, first
ensure that the heating system is filled and bled and that nei-
ther the brine pump nor the compressor can be started. This
is carried out by setting the operating mode to ADD.HEAT.
⚠ Any alarms that may occur in connection with the installation
can be fault-traced in the "Troubleshooting" section in the
service instructions.
For DHP-H Opti Pro SP (Single Phase) heat pumps it is imper-
⚠
ative that the maximum hot water temperature is altered
from the default factory setting from 95°C to 85°C. Refer to
