risk of electrical shock.
1. Be sure power is disconnected to motor when
working on electrical connections.
2. Remove the motor end cover, exposing motor shaft.
Momentarily start pump. If hookup is correct, the
shaft will rotate clockwise.
3. If rotation is not clockwise, reverse any two leads to
the starter. The rotation will now be correct.

risk of electric shock. This equipment
is only for use on 115V and is equipped with an
approved 3-conductor cord and 3-prong, grounding-
type plug. To reduce the risk of electric shock, be
certain that it is connected to a properly grounded,
grounding-type receptacle. Do not modify or remove
the plug. Make sure the pump circuit meets the
National Electrical Code. To avoid a dangerous
electrical shock hazard, keep the cord dry at all times.
Models without a cord or plug:
1. Connect ground wire first. Connect the ground wire to
the green grounding terminal provided under motor
canopy (see Figure 5) identified as GRD. Make the
ground connection to this terminal. Do not connect
the motor to an electrical power supply until the unit
is permanently grounded; otherwise a serious or fatal
electrical shock hazard may be caused.
2. For the best ground connection, connect to a
grounded lead in the service panel or to a metal
underground water pipe or well casing at least 10 ft.

run the ground wire directly to the metal well casing
or use a ground electrode furnished by the power
company.
lUBricatiON
It is not necessary to lubricate the pump or the motor.
The motor is equipped with sealed ball bearings,
lubricated for the life of the bearing. The mechanical
shaft seal in the pump is self-lubricating and requires
no adjustment. Disassemble the pump to replace the
seal (See "Maintenance", Pages 7 and 8).
OPEratiON
NOticE: Observe the following precautions when
operating the pump:
1. Keep the motor dry! Do not direct the stream from
pump discharge onto the motor!

pump with the discharge shutoff, as the hose may
burst or the pump may be damaged due to high
temperatures.
3. Do not use a standard trigger gun with this pump.
Use only trigger guns with an automatic weeping
feature. These are available as accessories and are
provided with three nozzles. The smallest nozzle
restricts the flow, allowing use of a smaller water
source. The two larger nozzles are used if the water
source will supply the pump's full capacity.
4. Do not run the pump dry; to do so may damage the
seal.
5. To avoid internal damage to the pump, Do not
operate with water at temperatures above 175
degrees F.
