2 When the unit is started up for the first time, or when the unit has
been out of operation for a longer period, it is recommended to
check the following.
Abnormal noise and vibrations
Make sure that the unit does not produce abnormal noises or
vibrations: check the fixation, stop valves and piping. If the
compressor makes abnormal noises, this may also be caused by
an overcharge of refrigerant.
3 If the water chiller does not start after a few minutes, refer to
"Troubleshooting" on page 14.
