Overview
These instructions are for upgrading the air cylinder
solenoid valve on all models of PR70 fixed or variable
ratio systems. The new solenoid valve, part #17K155,
included in this kit replaces part #120899. This kit
17J520 should be ordered if part #120899 fails and
needs to be replaced.
Important features of this upgrade kit include:
• It retains the existing dispense valve.
• The solenoid valve and dispense valve are
mounted to the air cylinder vertically instead of
horizontally.
• The cable harness included in the kit now has 4
cables instead of 3. The retract and extend sig-
nals have been split into separate cables. They
were combined into one cable previously.
