Operation
Startup
Before operating any component in the system,
check the following:
• The reservoir is securely fastened in the pump
assembly and that the fill cap or grease-fill fitting is
easily reached.
• The pump package is securely fastened in place.
• The gear reducer is filled with the proper lubricant,
see page 23.
• The electrical connections to any controllers, level
switches or pressure switches used on the system
are tight.
• All of the accessories plumbed into the output mani-
fold block assembly are secure.
• All of the hose or tube connections are tight.
• The reservoir is filled with lubricant. See Fill the
Reservoir , page 9.
• All filling and bleeding steps have been completed.
• The output of the pump assembly. To adjust the out-
put, see page 12.
• For models equipped with a clutch drive, verify it is
properly adjusted, see Clutch Drive Adjustment (if
equipped) , page 11.
The pump package is ready for operation.
While the system is operating, periodically check
the following components:
• The pump is cycling according to schedule.
• Visually check the unit for leaks and loose fittings.
Make sure that the hoses are not kinked or rubbing
on anything.
• If the reservoir is not equipped with a low-level
switch, visually check the lubricant level and refill
before all lubricant is used.
NOTE: If the reservoir is allowed to run out of lubri-
cant, excess air will be introduced into the system,
requiring that the system be bled.
Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
1. Verify pump is stopped and disconnected from the
power source.
2. Using a wrench, slowly loosen the outlet fitting (a,
F
IG
. 9) connected to the pump assembly until the fit-
ting is loose and no more lubricant or air is leaking
from the fitting.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection, splashing
fluid and moving parts, follow the Pressure Relief Pro-
cedure when you stop dispensing and before clean-
ing, checking, or servicing the equipment.
