12 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.

Also read chapter 1.2
12.1 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.
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
from circuit breaker when capacity exceeds specifications.

Do not touch refrigerant tubes with bare hands during operation. The refriger-
