20.1 Overview: Commissioning
After installation and once the field settings are defined, the installer is obliged to
verify correct operation. Therefore a test run MUST be performed according to the
procedures described below.
This chapter describes what you have to do and know to commission the system
after it is configured.
Commissioning typically consists of the following stages:
1 Checking the "Checklist before commissioning".
2 Performing a test run.
3 If necessary, correcting errors after abnormal completion of the test run.
4 Operating the system.
20.2 Precautions when commissioning
DANGER: RISK OF ELECTROCUTION
DANGER: RISK OF BURNING/SCALDING
CAUTION
Do not perform the test operation while working on the indoor units or the heat
exchanger unit.
When performing the test operation, not only the compressor unit will operate, but
the heat exchanger unit and the connected indoor units as well. Working on an
indoor unit or the heat exchanger unit while performing a test operation is
dangerous.
CAUTION
Do NOT insert fingers, rods or other objects into the air inlet or outlet. Do NOT
remove the fan guard. When the fan is rotating at high speed, it will cause injury.
