Commissioning
During commissioning of machine, anticipate the following specific risks:
Risk of total loss!
Faulty connections can cause unexpected startup of machine / uncontrolled
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 components.
Electrostatic processes / power failure can pose a risk for electronic compo-
nents and also result in software errors.
To avoid damage to machine or injuries during commissioning of machine, the fol-
lowing 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 commission-
ing.
Check motor for correct direction of rotation prior to commissioning.

Pre-startup checks
Before starting the heat pump, check the requirements according to the following
checklist.
All electrical feed lines in the corresponding cross-sections are
wired to the terminals, as per connection plan.
Main Switch is in „OFF“ position.
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.
Do not touch switch with wet hands. This poses a risk of electric shock.
The unit must be grounded. Do not connect the ground wire to gas or water
lines, lightning rods or telephone grounding lines. Improperly grounded unit
poses a risk of electric shock.
Use circuit breakers (ground fault interrupter). Failure of unit or fire may result
