04.12.2015
During commissioning of machine, anticipate the following specific risks:
Risk of total loss!
 Faulty connections can cause unexpected start-up of machine / uncon-
trolled machine operation.
 Mix up of connections causes motor to run in wrong direction; this could
damage the machine.
 Incorrectly wired connections can destroy electrical / electronic compo-
nents.
 Electrostatic processes / power failure can pose a risk for electronic
components and also result in software errors.
To avoid damage to machine or injuries during commissioning of machine,
the following points must be observed:
 Commissioning of machine shall only be performed by qualified persons,
in compliance with safety instructions.
 Activate all safety devices and emergency-stop switches prior to com-
missioning.
 Check motor for correct direction of rotation prior to commissioning.
 Also read chapter 1.2.
Before starting the heat pump, check the requirements according to the fol-
lowing checklist.
All electrical feed lines in the corresponding cross-sections are
wired to the terminals, as per connection plan.
Switch is in „0FF" position (no light).
The fuses in the fuse box are in compliance with the specifications
in the connection plan (LS switch, type C for compressor feed
line!).
The hydraulic connections for heat source, space heating and do-
mestic hot water are connected.
The hydraulic systems are filled with operating media and properly
vented.
Shut-off devices are open.
 Before operation, check if all plates, fuses and other protective devices
are properly installed. Components that are rotating, hot or under high
voltage can cause injuries.
Warning! Risc of electric shock!
Do not touch switch with wet hands. This poses a risk of electric shock.
