SHUTDOWN
11.1 Shutdown during summer
Heat pumps used exclusively for heating pur-
poses can be shut down for the summer time
(no hot water service). This is done by means of
the operating mode selector of the heat pump
control. Please observe the Installation and
Operating Instructions.
Due to the risk of frost damages, shutdown
without draining the heating circuit is permissible
only in regions where outdoor temperatures do
not drop below 0 °C .
11.2 Final decommissioning/disposal
Before removing the heat pump it is necessary to
disconnect all cables as well as the connections
to the heat source and the heating system.
Furthermore, all electrical supplies must be
switched off and all valves must be closed.
Please observe the applicable environmental
regulations in regard to recycling, reuse and
disposal of working materials and fluids accord-
ing to DIN EN 378, when taking the heat pump
out of operation. Especially the disposal of
refrigerants and refrigeration machine oil must
comply with the relevant regulations.
