Herz commotherm 30 SW, Operating Instructions Manual

Page: 11 / 80

The HERZ SW/WW heat pump is an “electrically
R410A”. An electrically driven compressor compresses and feeds the refrigerant through a pipe circuit
consisting of copper pipes, whereby pressure up to 43 bar may arise.
The device is under voltage. Removing the device
equipment parts may lead to serious physical harm.
The refrigerant supplied can affect surfaces of the equipment parts (pipes and
compressor) at temperatures of more than 100° C (
