Functional check of the compressor without edge device
To ensure a faultless work of the compressor by first starting proceed as follows:
Operate the compressor only in cool, dust-free, dry and well ventilated rooms.
The ambient temperature should not be below 5 ° C and above +40 ° C.
The slope of bearing surface in across-track and longitudinal directions should not be greater than 15
degrees to avoid damages of the compressor.
Make sure that the minimum distance is complied between the compressor and any possible obstacle to
air flow is 50 cm.
Before starting make sure that voltage and supply frequency correspond to data on the plate with char-
acteristics of the compressor.
ATTENTION!
Operation with power supply with out following above conditions can lead to compressor damage.
Connect the compressor only to appropriate power supply.
ATTENTION!
Pay attention to instructions about possible dangers in the chapter "Safety" beginning from page 5.
Check direction of rotation
Type TWINSTAR 690
To ensure the correct direction of rotation of the compressor by starting proceed as follows:
Before starting make sure that voltage and supply frequency correspond to data on the plate with char-
acteristics of the compressor.
Connect the compressor to the power supply.
Switch on the compressor using the switch to start it.
Make sure that the direction of impeller rotation coincides with the direction of the arrow on motor.
If the direction of impeller rotation does not coincide with the direction of the arrow on motor, follow these
steps:
Switch off the compressor with the switch.
Disconnect the compressor from power supply.
Lightly press on the phase switch (1) in Cekon-plug.
Turn the pressed phase switch at 180 ° C until it clicks.
Direction of impeller rotation is changed.
ATTENTION!
Operation from power supply witch does not fulfill above conditions can lead to compressor damage.
Connect the compressor only to appropriate power supply.
Check direction of rotation in each new use place.
ATTENTION!
Pay attention to instructions about possible dangers in the chapter "Safety" starting from page 5.
