The maintenance of the compressor drive motor includes the following activities:
•
•
10.4.15 Checking the operating parameters
Checking the operating parameters
Parameter to be checked
Discharge temperature
Oil temperature
Oil pressure
Compression discharge
pressure
Oil level in compressor
Oil heater
Setting the safety devices
Number of operating hours
102
Notice
Maintenance of the compressor drive motor must be carried out in accord-
ance with the "Motor documentation".
► The motor documentation is part of the product documentation.
Lubrication of the motor
Lubrication intervals and amounts according to the "motor documentation" or
"nameplate".
Cleaning the motor (externally)
Selection of a suitable cleaning agent according to the motor documentation.
Notice
The checking intervals recommended in the table must be observed.
► The control of the operating parameters is carried out via a Touch Panel.
The project-related setting values and limits are given in the parameter list.
► Inform the GEA Refrigeration Germany GmbH technical customer serv-
ice if the parameters are outside of the permissible limits.

Remark
Maximum discharge temperature 150 °C, in individual
cases (e.g. heat pump applications) this may be exceeded
in agreement with the manufacturer.
See parameter list!
The viscosity must not be less than 10cSt.
The oil difference pressure to the discharge pressure
must not be lower than 1.7 bar. In the event of an oil dif-
ference pressure fault, a contaminated oil filter may be the
cause.
See project value (parameter list). Determine the super-
heat temperature on the pressure side by comparison with
the final discharge temperature.
An oil level must be visible in the sight glass at all times. If
the oil level is below the bottom third of the sight glass,
refill oil.
When compressor is shut down, the heater must automat-
X
ically start.

See the setting values in the parameter list.
See maintenance instructions for maintenance work to be
carried out according to the number of operating hours.
