WARNING

Installation
4311628B
Installation
When unpacking pump, check for shipping damage.
Report any shipping damage to delivering carrier imme-
diately.
Mounting Pump
1. Apply herbicide compatible sealant to large thread
on bung adapter (9) (2 in. x 1-1/2 in. reducer fitting).
Install bung adapter on tank.
2. Assemble suction tube sections by applying PVC
cement (supplied with your pump) to the inside
diameter of the PVC couplers. Make sure PVC
cement is applied to the complete inside diameter
and slide the pipe sections into the coupler with a
twisting motion.
3. Cut the suction tube so that it is 2 in. (55 mm) from
the bottom of the tank when installed in the tank.
4. Insert inlet gasket (7) into union nut (1k). Apply a
herbicide compatible sealant to the threads on the
suction tube assembly (5c) and screw the suction
tube into the pump inlet (1j).
5. Insert suction tube attached to pump through bung
adapter (9) into tank. Position pump as desired and
tighten union nut (1k) on bung adapter (9).
Mounting Hose and Nozzle
1. Apply herbicide compatible sealant to male threads
on the street elbow fitting (1e) and screw fitting into
the 3/4 in. npt outlet port on the top of pump. Do not
over tighten.
2. Apply herbicide compatible sealant to threads on
both ends of the hose assembly. Screw one end of
hose into the female thread on the fitting (1e) and
tighten.
3. Screw nozzle onto the other end of hose and
tighten.
Electrical Installation
12 VDC
To install wiring for a negative ground system:
1. Ensure pump switch is OFF.
2. To remove electrical cover (2a), remove four bolts
(2c).
3. Strip 3 in. (76 mm) of outside insulation from power
cable (6c) from end opposite of fuse.
4. Strip 3/8 in. (10 mm) of insulation from red and black
wires.
5. Slide strain relief (6b) over end of power cable (6c)
on the end just stripped. Male thread of strain relief
should be toward stripped end.
6. Insert power cable through conduit thread in electri-
cal cover (2a). Connect wires from power cable to
wires from the motor using wire nuts (2e): red to red
and black to black.
CAUTION
Do not use a curb pump automatic shut-off nozzle
with this pump. Use of a curb pump automatic nozzle
may cause priming problems, reduced output flow,
and motor overheating. If an automatic shut-off nozzle
is required, use Graco part number 260082 (regular)
or 260083 (unleaded) or Catlow, Inc. part number
NCLF-1 (regular) or NCNLF-1 (unleaded).
CAUTION
• Ensure tank being used is clean and free of welding
slag.
• Ensure the tank has a vent to allow air into the tank
as the herbicide is being pumped out. Failure to
vent tank will cause priming problems.
For tanks deeper than 36 in. (914 mm) you will
need a standard 1 in. (25 mm) pipe with 1 in. npt
threads on one end. Suction tubes longer than 60
in. (1.52 m) require a foot valve (Graco Part No.
260217) at the bottom of the tube to prevent loss of
prime.
Power cable can be cut to shorter length if 18 feet
(5.5 m) is not required. Cut to proper length and
proceed with steps 3 and 4.

Installation
311628B 5
7. Screw strain relief (6b) into electrical cover (2a).
8. Position power cable (6c) so the large diameter of
power cable extends through strain relief (6b).
9. Tighten nut on strain relief to form a seal around the
power cable.
10. Reinstall electrical cover (2a) on the pump.
11. Remove 1/2 in. (13 mm) of insulation from wires on
the fuse holder end of the power cable.
12. Attach battery clamps (6a) with red sleeve to red
wire and black sleeve to black wire. Wire must be
crimped to the battery clamp firmly to get a good
electrical connection.
13. Connect red wire with fuse holder inline to positive
battery terminal. Connect black wire to negative bat-
tery terminal.
Electrical Installation
115 VAC
1. Ensure pump switch is OFF and electrical power is
disconnected.
2. Install conduit and user-supplied power cord to
pump.
3. Strip 3 in. (76 mm) from power cord jacket and 1/2
in. (13 mm) from individual conductor insulation.
4. To remove electrical cover (2a), remove four bolts
(2c).
5. Remove 1/2 in. (13 mm) of insulation from power
wires inside pump electrical terminal cavity.
6. Insert electrical power wire through conduit opening
in back of pump.
7. Using wire nuts (2e), connect wires: green to green,
white to white, and black to black.
8. Replace electrical cover.
Priming Pump
1. All pump models will prime with no fluid in the
pumping chamber to a height of 5 ft (1.52 m). If
pump fails to prime, remove hose from street elbow
fitting on pump outlet and pour 8 oz (0.24 liter) of
motor oil into the pump outlet port.
2. If suction height is too great, the pump may lose its
prime if the nozzle is opened with the pump turned
off.
3. To hold fluid in the suction tube, a check valve
(Graco Part No. 260217) may be required on the
bottom of tanks with a suction height over 5 ft (1.52
m).
4. The tank must be vented or the pump may not prime
or may lose its prime due to a vacuum in the tank.
On 115 VAC pumps, electrical connections must be
made by a licensed electrician per requirements of
local, state, and national codes regarding class 1,
group D installations. Only rigid conduit with
threaded connections should be used. Conduit
opening in pump must be sealed with waterproof,
herbicide-resistant sealant. Failure to comply with
this warning could result in injury from electrical
shock.

Operation
6311628B
Operation
On/Off switch lever (8d) is located under nozzle holder.
Remove nozzle before turning pump on.
1. Move switch lever (8d) on.
2. Insert nozzle into tank and actuate nozzle lever to
dispense herbicide.
3. Immediately after dispensing herbicide turn switch
lever (8d) off.
Maintenance
1. Clean inlet strainer (3b) after every 50 hours of
operation.
2. To remove inlet strainer (3b), remove four screws
(3c) and strainer cover (3a). Remove and clean
strainer.
3. If strainer is excessively dirty, clean tank to protect
pump and the equipment.
4. After cleaning strainer, replace strainer and cover.
Make sure cover seal (3d) is in place.
Flushing Pump
Proper flushing of pump after use with herbicides and
chemicals is essential for long service life. Many herbi-
cides dry quickly and will make pump inoperative if
allowed to dry inside pump.
1. Remove pump from tank and insert suction tube into
water or chemical agent recommended by chemical
manufacturer.
2. Operate pump until fluid discharge is free of chemi-
cal.
3. For extended storage after use with herbicide or
chemical, flush pump and fill with diesel fuel.
Before servicing, turn pump off and open the
nozzle to relieve pressure.
CAUTION
Do not operate pump dry. Do not run pump for more
than 5 minutes with nozzle closed. Do not operate
pump for more than 30 minutes continuously in 1 hour.
CAUTION
All fluids pumped must be compatible with wetted
parts listed on page 12.
