SYSTEM INSTALLATION AND START UP
(For Dualine Automatic Electric Powered and Air Powered Systems)
First study the schematic layout, the bearing list, and the applicable Farval publications describing dualine systems.
Together they completely describe the system and its component assemblies. They also explain how the system and
its component assemblies operate and how the various sub-assemblies-the pump, the reservoir, valve manifolds, and
controls should be combined. In addition to becoming well acquainted with the lubricating system, it is often helpful to
sketch the location of all manifolds and lube lines on the machine with chalk or crayon.
INSTALLATION
Pump Reservoir Assembly-Locate where it is protected from dirt and where it can be easily maintained and filled with
lubricant. Bolt to a solid foundation (except air powered barrel pumps).
Measuring Valves-Mount on a flat surface close to the bearings (within 10 feet) and close to the machine for protection
but where accessible for adjusting and servicing. Valves may be mounted in any position but indicator stems should be
visible and should face the same direction for easier checking. Mount with indicator stems down if excessive dirt and
scale are present or order U-1732 indicator covers.
Adjacent valve blocks may be piped together before mounting, using one union in each pipe connection between
valves. Any welding of valve support brackets to the machine should be done before mounting valves.
Supply Lines-Clean inside of all pipe, not meeting Bulletin 1800 pipe specifications, as follows: (a) if unpickled black
pipe- shot or sandblasting, solvents, or a tube descaler (b) if galvanized pipe-drifting or sandblasting. Remove scale
and spatter from pipe welds by thoroughly pounding, tapping, and blowing out with air. Remove chips produced by
threading pipe before connections are made.
Prefill measuring valve to bearing discharge lines of grease systems with clean grease. It saves startup time and pre-
vents overfilling of short discharge lines while waiting for long discharge lines to fill. Use hand pump, grease gun, or
power pump. Fill entire coil of copper tubing with grease before cutting and installing.
Keep lines short. Place close to machine for protection and cover with a protective shield in hazardous locations.
Clamp rigidly. Connect each supply line to the same port on each measuring valve (see Figs. 1 and 2) so that indicator
stems will move in the same direction, making erratic performance more obvious. Do not connect discharge lines to
bearings until later (see page DC1-3 under “Bearings”).
Bleeder Valves-Install at high points to purge system of air.
Line Strainers and Line Checks-Install as shown in Fig. 1.

Pressure Control Switches (End-of-Line Systems with FR Reversing Valves)-Can locate anywhere in the line. If there is
more than one set of main supply lines, install switches in the set with greatest pressure drop (usually the longest) and in others
with pressure drops of similar magnitude. See Fig. 2.
Pressure Gauges (End-of-Line Systems with DR Reversing Valves)-Add pressure gauge U-902F (0-5000 psi) where distribu-
tion line ends at last measuring valve to help adjust system pressure during start up period.
Electric Wiring-Connect motor so that pump rotates as shown in the detail section. If there is more than one set of main supply
lines with pressure control switches, wire. the corresponding switches in each main line in series so that full line pressure devel-
ops throughout system before pump stops. See appropriate controller bulletin for wiring diagram.

The procedure described below assures removal of air from all parts of the system. Air, trapped in the pump throat, can prevent
priming on the first stroke and result in damaging the pump cylinder and piston. Air, trapped in the supply lines, will prevent the
pump from developing system shut down pressure without long operating periods and subsequent time-out of the fault signal
timer.
Pump Gear Housing (CS1000, CS2000, DC41 and DC42 only): Before starting pump, fill gear housing to level shown in the
applicable drawing in the pump section with a compounded steam cylinder oil containing 5 to 10% acidless tallow with a viscosity
of 150 SSU at 210 F. Change two weeks after the initial fill and yearly thereafter.
Reservoir:* Fill with clean lubricant.
A. CS1000 & CS2000 Grease Reservoirs: Fill until grease exhausts thru relief hole on top.
B. DC41, and DC42 Grease Reservoirs when Completely Empty: To eliminate air, add several quarts of heavy cylinder oil
before filling balance with grease. Also, open air bleeder valve U - 127B (it is located near top of the follower indicator rod)
to permit excape of air below follower plate.
Air Control Panel. Set controls on air control panel to meet requirements of the air barrel pump.
Supply Lines (air barrel pumps only): Fill the pump to reversing valve lube supply hose by disconnecting it at the point where
it attaches to the reversing valve inlet port and operating the pump until lubricant appears at the end of the hose. The pump may
be started and stopped by manually tripping the reset lever on the timer, or operating the manual override button on top of the air
pump’s solenoid valve. Re-connect the hose.
Supply Lines: Fill With clean lubricant by operating system pump† or, preferably by using a high volume high pressure barrel
pump. During this period, disconnect both main lines at their terminating point. This is at the reversing valve if lines form a com-
plete loop or at the last measuring valve if lines end there. Open air bleeder valves located at high points in the pipe lines and then
close them in sequence starting with the pump and working outward as lubricant, free of air and foreign matter, emerges. When
lubricant flows from the end of one line free of air and foreign matter, reconnect that line, and run pump until reversing valve oper-
ates Allow pressure to dissipate in that line then fill, purge, and reconnect the other line in the same manner.
NOTE: Disconnecting of supply lines helps operator identify lines of systems with DR4 type reversing valves (CS2000
and DC42). Supply line #1 must connect to return line #1 and supply line #2 to return line #2.
Fill and purge branch lines leading off main supply lines as described above. Branch lines must be unplugged at their ends
until a solid flow of clean, air-free lubricant appears. See Fig. 1.
Bearings: Fill with lubricant. To assure removal of all air, use a hand gun or oil can. Connect discharge lines to the bearings.

†CAUTION: Pump drive shaft must rotate In direction recommended In applicable pump section or as shown by arrow on pump housing.
Incorrect direct on of rotalion will damage CS1000, CS2000, DC41 or DC42 pumps

System Pressure-Adjust to between 300 and 700 psig at the end of the most remote branch of the main supply lines (600 psig
is usually satisfactory) by turning the pressure adjusting screw.- This pressure is indicated by gauges at the adjustment point (for
example the “B” gauges in Figs. 4 and 5).
Note: Pressure drop thru the systems shown below equals the difference between the “A” and “B” gauges. It results from pressure
losses in the supply lines, in the measuring valves, and in injecting lubricant into the bearing. With pressure set at 600 psig on the
“B” gauge, pressure at the “A” gauge might be as high as 1200 psig but varies somewhat with the temperature (it tends to rise with
falling temperatures) even though return line pressure gauge readings remain constant. If the system has been shut down for a
number of hours, pumping time for the first two or three cycles may be 10 to 15% longer than for subsequent cycles.
Timer---Set the station timer.

SERVICE INSTRUCTIONS–MAINTENANCE
INTRODUCTION
This section covers service and trouble shooting instructions for complete automatic systems. Additional instructions for various
system components may be found in other publications covering specific systems.
PREVENTIVE MAINTENANCE
1. Keep reservoir filled . A pump operating with an empty reservoir will force air into the system causing difficulty in building pres-
sure, preventing pump from priming, or even damaging the pump pistons.
2. Use clean lubricant-foreign matter may clog pump or reservoir filler screen. Keep the line strainers clean. They are usually in-
stalled in the lines near the reversing valve. Reservoirs should be filled by a portable grease pak or drum transfer pump.
• CS1000 and SC2000-clean filler screen and filler connection assembly regularly and pressure relief valve as needed.
See applicable pump section.
• DC41 and DC42-Strainer-pressure relief valve assembly (shown in Fig. 4 Page DC1-4): Clean strainer-screen at regular
intervals and pressure relief valve as needed.
3. Inspect entire system regularly including tubing and hose (replace if damaged), connections (they should be tight), all bearings
(a small amount of lubricant should show at the edge of each one), and measuring valve stems (they operate during each lube
cycle.)
WARNING: All CS1000 and CS2000 grease reservoirs are equipped with springs which produce a force of 200 pounds
when reservoir is filled. Empty reservoir before removing its top end cap.
HOW TO LOCATE AND CORRECT TROUBLE
1. To locate trouble, replace distribution lines at the reversing valve as follows:
• On loop systems, form two pieces of copper tubing into loops. Connect each loop between a discharge port of the reversing
valve and its corresponding return port. Flatten the loops sufficiently at the center to build resistance. Start pump with timer.
If pump builds pressure and the reversing valve operates at normal system pressure the trouble is in the lines.
• On systems with no return, install a pipe plug in each discharge port of the reversing valve. Start pump with timer. If it can
build pressure to the relief valve setting (normally it is factory set at: 2400-2500 psi on DC41 & DC42; 1400-1500 psi on
CS1000 & CS2000), the trouble is in the lines.
Note: Solenoid reversing valves can be checked hydraulically by operating them manually. Remove the plastic plugs at each
end and push the piston back and forth.
2. Air in system shows up when the pump fails to build pressure, to prime properly, or when grease level indicator stem rises faster
than it should after the system is operated. Correct by cleaning out reservoir and then filling and purging the entire system as
described under Start Up Procedure.

CONDITION CAUSE

not have free wheeling clutches).
6. Suction strainer screen dirty. (DC36 only).
7. Pump shaft seal worn (DC36 only).
8. Pump cylinder not shimmed correctly. (All
except DC36 & air operated barrel pumps).
9. Pump worn. (All except air operated barrel
pumps).
10. Pump-motor coupling loose.

2. Air in system.
3. Crossed lines (for loop systems only).
4. Reversing valve damaged.
5. Pilot piston missing.
REMEDY
1. Find break and replace line.
2. Bleed air (Page DC1-3). Check lube level in
reservoir.
3. Check lube viscosity. Check for air in reservoir.
4. lncrease pressure setting, tighten retainer screws, or
clean as needed.
5. Repair. Check wiring and change rotation . See pump
section for correct pump drive shaft rotation.
6. Clean or replace.
7. Squirt oil on pump shaft next to shaft seal. If pump
then primes, seal is worn and pump or seal should
be changed.
8. Re-shim per applicable pump section.
9. Check pump output--page DD1-1. If it cannot build
pressure, replace piston and cylinder per applicable
pump section. If a DC36, replace entire pump.
10. Check and tighten.
11. Pressure one supply line to see if all flow comes
back thru 2nd line in relief. If so, isolate valves one
at a time starting at pump and working outward until
valve without piston is found. Also check items A4
and A6 above.
1. Tighten.
2. Bleed air (Page DC1-3). Check lube level in
reservoir.
3. Supply line #1 must connect to return line #1 and
supply line #2 to return line #2.
4. Disassemble and inspect.
