SAFETY WARNINGS
BEFORE OPERATING OR
INSTALLING THIS PUMP, READ
THIS MANUAL AND FOLLOW ALL
SAFETY RULES AND OPERATING
INSTRUCTIONS.
WARNING - ELECTRICAL PRECAUTIONS
All wiring, electrical connections, and system grounding
must comply with the National Electrical Code (NEC) and
with any local codes and ordinances. Employ a licensed
electrician.
FOR DUAL VOLTAGE MOTORS:
Voltage change instructions are located on motor label or on
wiring access cover.
WARNING - RISK OF ELECTRICAL SHOCK
. This pump is supplied with a grounding conductor and grounding
type attachment plug.
. To reduce risk of electrical shock, be certain that it is connected
only to a properly grounded, grounding-type receptacle.
APPLICATION
This jet sprinkler pump is a versitile pump for pressure boosting:
small underground sprinkler systems: operating lawn sprinklers and
a multitude of other general purpose applications. This pump is
suitable for installations where the vertical distance from the pump

INSTALLATION
a) Pump Location: The pump should be installed in a clean, dry and
ventilated location which provides adequate room for servicing and
protection from freezing temperatures. It should be bolted to a good
foundation, preferably concrete and provided adequate drainage.
Locating the pump as close as possible to the water source reduces
the friction in the suction pipe and will give maximum capacities.
b) Suction pipe: It is recommended that only new, clean 1-1/4 inch
pipe or hose be used. If the pump is installed any appreciable
distance away from the source of water, the suction pipe should be
increased to 1-1/2 inch. Horizontal lengths of pipe must gradually
slope upwards from the source of water to the pump to avoid air
pockets in the line. Thread compound should be used on all pipe

. A ground fault interrupter (GFI) protected circuit is recommended for
use with any electrical device operating near water.
. Have an electrician provide an outlet near the point of use. For
recommended cable size see table 1.
. Pump and motor must be protected from the weather, for indoor use
only.
. Motor must be grounded and terminal cover in place to reduce
electrical shock hazard.
. Keep motor operating area as dry as possible.
. Always disconnect power before servicing.
. Not investigated for use in swimming pool area.

drawdown. In offset installations, friction losses in the suction pipe
must be taken into consideration. (Refer to Table 2, Friction loss
Chart).

joints and connections should be thoroughly tightened. A foot
valve must be installed and its operation should be checked
since a leak will prevent proper operation of the system. Make
sure that the foot valve is located so that it will be submerged at
all times. If a sand point or driven well is used, install a check
valve next to the pump suction instead of the foot valve. For
booster pump applications no foot valve is required.
c) Service Line: The service line should be connected as shown
in Fig. 1. The size of the service line required is governed
entirely by the amount of water needed and the length of the
pipe. The pipe selected should be large enough so that the
friction loss (determined fromTable 2, Friction Loss Chart) will
never exceed a 20 ft. (6m) head.
