Reservoir Mounting
1. Mount Reservoir (K) on sturdy, flat surface with 6
(six) 3/8 inch diameter bolts. Note location of Fill
Port (G), Overflow port (H), and Low Level (T) and
Lubricant Outlet Connection (A) for easy access
once installed.
2. Connect High Pressure Lubricant Supply Line (D) to
the Lubricant Outlet Connection (A).
3. Ground system (see
Grounding
). Mount reservoir
to grounded chassis member.
Pump (B)
Pump instructions are provided in the Dyna-Star HP or
HF Pump instruction manual 332514 provided with your
system.
Pump Module Operation
The pump module provides lubricant flow and pressure
to operate a single line parallel automatic lubrication
system.
The module requires an electrical power supply and a
timed signal from a lubrication controller (F). Based on
these signals, the pump module provides lubricant flow
and pressure to operate the injectors (E) and vents the
injector system to reset the indicators.
1. At the start of the cycle, the lubrication controller (F)
initiates a signal, closing the vent valve (L) and start-
ing the pump (B).
2. The pump (B) builds pressure in supply line (D) until
all the injectors have actuated. Then the pressure
switch sends a signal to the lubrication controller
(F), ending the cycle.
3. The lubrication controller (F) terminates the signal
to the pump (B) and power to the vent valve (L).
4. The vent valve (L) opens.
5. Pressure in the supply line (D) is relieved back into
the reservoir, resetting all injectors (E).
Inlet and Outlet Components
Vent Valve (L)
The vent valve is used to reduce system pressure and
allow the injector to reset. When energized, the valve
closes and holds pressure through the outlet port
(marked “0”) on the vent valve. When de-energized, it
vents pressure internally to tank.
Refer to the Dyna-Star HP or HF Vent Valve Kit manual
332515 for installation and operation instructions.
LIFTING HAZARD
This equipment is heavy. Lifting or moving heavy
equipment incorrectly can cause serious injury such
as muscle strain or back injuries. To avoid injury:
•
Do not lift or move this equipment without assis-
tance.
• Always use a lifting device secured to the pump lift
ring when moving or installing this equipment. See
Technical Data, page 23 for pump weight.
COMPONENT RUPTURE HAZARD
The maximum working pressure of the inlet and outlet
components in the system vary. Over-pressurizing an
inlet or outlet can cause it to rupture resulting in prop-
erty damage and serious injury such as skin injection
or injury from splashing fluid. To reduce the risk of
component rupture:
•
Be sure to know the maximum working pressure of
each inlet and outlet component in the system.
• Never exceed the maximum working pressure of
the inlet and outlet components.
