If there is a jumper in the terminal strip of the compressor connected to a cabinet,
the switch on the compressor cabinet will not work!
If we want to connect a new cabinet to a compressor that previously worked alone (a compressor
without a cabinet), then it is necessary to cancel the connection in the compressor terminal strip by
performing the procedure, see further. (Fig. 27, Fig. 28). (See also chap. 13.1 and 13.2).
PROCESS:
Jumper removal (D-C-B-A process)
• Disconnect the product from the mains by pulling the plug out of the socket.
• Remove the cover on the electrical panel (on the compressor).
• The jumper is in the terminal strip – D
• Lift up the fuse cover – C
• Remove the jumper from the terminal strip – B
• Close the fuse cover – A
• Reinstall the cover on the electrical panel.
• Insert the compressor into the box.
• Connect the cabinet to the compressor by inserting the power cord with connector into a power
socket. (Fig. 13)
• Connect the connector to the display on the front door of the cabinet.
• Connect the device to the electrical mains.
• Activate the compressor by turning on the switch on the pressure switch and the switch (4) on
the cabinet (Fig. 23).
Compressor with cabinet - when operating in the cabinet, there must not be an electrical connection.
(Fig. 27 pos. A,B, Fig. 28 pos A).
Note: In case of using a compressor without a cabinet or in case of maintenance, a jumper
which is not installed into the terminal strip should be kept in a designated place next to the
electrical panel.
23.10. Cleaning and disinfection of the exterior surfaces of the product
Clean and disinfect the exterior surfaces with neutral cleaning products.
Use of aggressive detergents and disinfectants containing alcohol and chlorides
can lead to surface damage and discolouration.
23.11. Inspecting the cooled and fan
The equipment, in particular the compressor fan, cooler fan, and the cooler, must be kept clean to
ensure efficient drying. Remove dust from the surface of the cooling fins and fans by vacuuming or
blowing down with compressed air.
23.12. Dew point sensor calibration
It is recommended to calibrate the dew point sensor every 2 years on compressors equipped with
this sensor. Calibration is performed by the manufacturer (Vaisala) and must be ordered online.
