Operation
12 312349G
Fill Reservoir
(For these instructions see FIG. 4, page 8.)
1. Connect lubricant supply hose from remote filling
station pump to Fill Port (K).
2. Connect High Pressure Lubricant Supply Line (G) to
Vent Valve (U) outlet.
3. Remove plug from Overflow Port (L).
4. Slowly turn on supply lubricant until level of lubricant
reaches overflow port.
5. Set hydraulic pressure to pump at lowest pressure
needed (see Technical Data, page 18).
6. Set hydraulic flow rate to pump at lowest rate
needed to get desired results.
7. Read and follow instructions supplied with each
system component.
Shutdown
(For these instructions, see FIG. 4, page 8.)
1. For normal system shut down, disconnect power to
Lubricator Controller (J) by turning off the ignition
switch.
2. Turn of hydraulic supply by closing the Ball Valve
(AA).
For systems with a follow plate, fill until the fol-
low plate reaches the overflow port.
Refer to Automatic Lubrication System Design
Guidelines Manual 309015 for instructions on
priming remaining system lubricant lines and
further operating instructions.
COMPONENT RUPTURE HAZARD
The maximum working pressure of each component
in the system may not be the same. To reduce the
risk of overpressurizing any component in the
system, be sure you know the maximum working
pressure of each component. Never exceed the
maximum working pressure of the lowest rated
component in the system. Overpressurizing any
component can result in rupture, fire, explosion,
property damage and serious injury.
Regulate hydraulic pressure to the pump so that no
fluid line, component or accessory is over
pressurized.
With a primed pump and sufficient hydraulic supply,
the pump starts when the timer activates the sole-
noid valve. The pump stops when the timer deacti-
vates the solenoid valve.
CAUTION
Never allow pump to run dry of the fluid being
pumped. A dry pump will quickly accelerate to a high
speed, possibly damaging the pump. If your pump
accelerates quickly, or is running too fast, stop the
pump immediately and check the fluid supply.
