Tubing (Pump to Output Device)
Where possible, it is strongly recommended that the line from the drum vacuum
pump be hard-piped to improve the performance of the system. Use 2 in. Schedule
40 PVC tubing from the drum vacuum pump to the output device.
Kodak supplies 15.2 m (50 ft.) of 2 in. ID flexible vacuum hose to connect the
vacuum pump with the output device. This is the maximum length permissible
without degrading the media-holding performance of the pump. If PVC piping is
used, the total allowable vacuum line length (length of piping plus length of flexible
hose) may be increased to 18.3 m (60 ft.). Keep the number of fittings to a minimum
and use long-radius PVC conduit elbows. The customer is responsible for supplying
and installing any PVC vacuum piping for the drum vacuum system.
Drum Vacuum Drive
The drum vacuum drive panel assembly must be mounted indoors on a vertical wall
or surface within 7.6 m (25 ft.) of the output device. It must be secured with four
screws through the four 8.5 mm (11/32 in.) holes in the back of the drive panel.
