Installing the Oil Tank Monitor
NOTE:
Although the Oil Tank Monitor is rated for a max-
imum air working pressure of 150 psi and has a recom-
mended operating pressure of 90 psi, Graco

Graco Diaphragm pumps.
NOTE:
If an air regulator is to be used, be sure that it is
connected to the air inlet port of the oil level monitor.
See Fig 1 Graco Used Oil Evacuation Installation Guide.
