SAFETY INFORMATION
Please read and understand this entire manual before attempting to assemble, operate or install the
product.
• NOTE: Pumps with the “UL” Mark and pumps with the “US” mark are tested to UL Standard
UL778.CSA certied pumps are certied to CSA Standard C22.2 No. 108. (CUS)
DANGER
ELECTRICAL SHOCK HAZARD.
Always disconnect power source before performing any work on or near the motor or its
connected load. If the power disconnect point is out-of-sight, lock it in the open position and tag it
to prevent unexpected application of power. Failure to do so could result in fatal electrical shock.
ELECTRICAL SHOCK HAZARD.
Do not handle the pump with wet hands or when standing in water as fatal electrical shock could
occur. Disconnect main power before handling unit for ANY REASON!
RISK OF ELECTRIC SHOCK.
These pumps have not been investigated for use in swimming pool areas.
WARNING
ELECTRICAL SHOCK ALERT.
Follow all local electrical and safety codes, as well as the National Electrical Code (NEC) and the
Occupational Safety and Health Act (OSHA).
ELECTRICAL SHOCK ALERT.
Replace damaged or worn wiring cord immediately.
ELECTRICAL SHOCK ALERT.
Do not kink power cable and never allow the cable to come in contact with oil, grease, hot surfaces,
or chemicals.
ELECTRICAL SHOCK ALERT.
Unit must be securely and adequately electrically grounded. This can be accomplished by wiring
the unit to a ground metal-clad raceway system or by using a separate ground wire connected to
the bare metal of the motor frame or other suitable means.
CHEMICAL ALERT.
This product contains chemicals known to the State of California to cause cancer and birth defects
or other reproductive harm.
CAUTION
ELECTRICAL SHOCK MAY OCCUR
Protect the power cable from coming in contact with sharp objects.
HOT SURFACE MAY CAUSE BURNS
Be careful when touching the exterior of an operating motor - It may be hot enough to be painful or cause injury.
PRODUCT DAMAGE MAY RESULT
Make certain that the power source conforms to the requirements of your equipment.

PREPARATION
Before beginning installation of product, make sure all parts are present. Compare parts with package
contents drawing. If any part is missing or damaged, do not attempt to assemble the product. Contact
customer service for replacement parts.
Estimated Installation Time: 2 hours.
Tools Required for Assembly (not included): Hacksaw, Pipe Wrenches (2), Wire Strippers, Needle-
Nose Pliers, Phillips Screwdriver, Wire Cutters, Adjustable Wrench
Parts Required For Assembly (not included): 2 in. Sched 40 PVC pipe, 1-1/2 in. Sched 40 PVC
pipe, 2 in. MPT x 2 in. slip adaptor, 1-1/2 in. MPT x 1-1/2 in. slip adaptor, 1-1/2 in. pipe tee, 1-1/2 in.
slip x 1-1/4 in. FPT reducer bushing, 1-1/4 in. MPT plug, 2 in. 90º pipe elbow, 1-1/2 in. 90º pipe elbow,
thread tape, 1/4 in. electric wire strain relief, 2-step PVC glue system (primer and sealer), and thread
paste.
Optional Parts For Assembly (not included):
1. Priming Plug with Pressure Gauge: Used instead of a priming plug alone. Helps determine if
the pump is primed, indicates if the pump is operating properly and what kind of pressure is in the
system when operating.
(1) 1-1/4 in. MPT x 1/2 in. FPT reducer bushing
(1) 1/2 in. MPT x 1/4 in. FPT reducer bushing
(1) 100 PSI pressure gauge
2. Unions: Used for easy removal of the pump from the sprinkler system.
(2) 2 in. union
(1) 1-1/2 in. union
3. (1) 1-1/2 in. Ball Valve: Prevents back flow of water from the sprinkler system when the pump is
removed from the system.
4. 1-1/2 in. Couplers: Quantity determined by the total length of pipe used.
5. 2 in. Couplers: Quantity determined by the total length of pipe used.

GENERAL PUMP INFORMATION
Typical Pump Setup
Typical setups for lawn sprinkler pump systems
include ground water wells (Fig. 1) or surface
water, such as lakes, ponds or streams. (Fig. 3)
Location
For best performance, the pump must be
located as close to the water source as possible
and protected from the elements.
Ventilation
Ventilation and drainage must be provided to
prevent damage to the motor from heat and
moisture.
Freezing
The pump and all piping must be protected from
freezing. If freezing weather is forecast, drain
pump or remove completely from the sprinkler
system.
Water Supply
The water source must be able to supply
enough water to satisfy the capacity of the pump
and water needs. See performance chart on
page 21.

WARNING: NEVER run pump (A) against a

pump, causing hazardous pressure in unit, risk

GENERAL PUMP INFORMATION
Valve
Vertical Lift
Vertical lift is the vertical distance from the
lowest level of the water to the pump intake. The
pump will move water as long as the pump is
within 25 vertical feet of the water source.
Horizontal Distance
The horizontal distance is the horizontal
measurement between the pump inlet and the
water source. This distance may affect the ability
of the pump to operate. If it is over 150 feet, call
customer service at 1-800-742-5044.
Pipe And Fittings
Use galvanized steel or NSF PW Schedule 40
PVC pipe and fittings. This material is designed
for water pressure and will seal against air
and water under pressure. Do Not Use: DWV
fittings, as these are designed for drains without
pressure and will not seal properly.
CAUTION: The entire system must be
air and water tight for efficient operation and to
maintain prime.
Wire Size:
The wire size is determined by the distance
from the breaker box to the pump motor, and
the horsepower rating of the motor. See the wire
chart on page 15 for proper wire size.

PUMP PREPARATION FOR WELL AND SURFACE WATER
CAUTION: Dry-t entire assembly to ensure proper t before gluing or taping parts.
CAUTION: Follow all proper gluing procedures as specied by the glue manufacturer. Always glue
in a vertical direction whenever possible to prevent glue from dripping inside pipe or ttings
CAUTION: Use thread tape and a thread paste compound on all male threads except for the
unions. Tighten securely with a wrench and add another 1/4 turn to ensure proper seal.
