tion you need to

trol is OFF.
• The discharge period can be
changed at anytime to suit equip-
ment demands or planned mainte-
nance cycles.
• The current discharge setting is
always displayed.
Preparing for Installation
Use the following procedure to check the
counter pressure of the application prior to
installation.
NOTE:
• Be sure to use a lubricant cartridge that
contains the same grease used in the
application.
• The best measurement results are
achieved during operation.
Checking the Counter Pressure
NOTE: An EM-Single Point Lubricator contain-
ing the same lubricant you are dispensing is
required to perform the Counter Pressure test
correctly. Contact Graco Customer Service or
your local Graco distributor to order this part.
Graco recommends checking the counter
pressure by connecting an EM-Single Point
Lubricator to a pressure manometer (user sup-
plied).
A pressure manometer is a simple device that
measures pressure output. To build a pressure
manometer you need a pressure gage (aa),
tee fitting (bb) and stop valve (cc). F
IG. 3
shows a correctly assembled pressure
manometer, connected to the lubricator and a
lubrication point.
Counter Pressure Test Procedure
1. Clean the lubrication point to remove any
potential contaminants.
2. Remove the plug (A).
