SEASONAL SERVICE
It is necessary to drain the entire system where the
pump, tank, and piping will be subjected to freezing.
Vertical pumps have a drain plug located on the side
of the pump casing near the bottom of the pump. Ho-
rizontal pumps may have two drain plugs, one on the
casing (part where pipes attach) and another on the
motor adapter. They are also located near the bottom
of the pump. Multi-stage pumps also have 1 or 2 drain
plugs and they may require you to tip the pump or
blow compressed air in one hole to get all the water
out of the stages.
Power the Motor
The electrical supply must be a separate
branch circuit with a properly sized breaker
or fuses. All wiring must conform to National
(NEC), CSA, state, provincial, and local codes.
Power supply voltage, phase and controls must
match motor.
NEVER RUN A PUMP DRY, DAMAGE WILL RESULT,
AND THE WARRANTY WILL BE VOIDED!
ALWAYS DISCONNECT AND LOCK-OUT ALL
ELECTRICAL POWER WHEN INSTALLING
OR WORKING ON PUMPS, MOTORS, OR
SWITCHES. INSURE THE POWER SUPPLY
BREAKER IS OFF OR THE DISCONNECT
(WHERE USED) IS OFF.
Remove the pressure switch cover. Attach the power
supply wires, either 115 or 230 depending on the mo-
tor voltage, to the Line terminals of the pressure switch.
Attach the green or bare ground wire to either green
ground screw in the switch. It makes no difference which
Line terminal you attach the hot- L1 (usually Black) and
neutral- N (usually white) 115 volt wires to on the switch.
The same goes for a 230 volt hook-up, either wire can go
on either Line terminal. Re-install the switch cover.
NOTE:
Motor voltage is NOT changed in the pressure switch.
See Fig. 7 in Technical Data
.
Check to insure that the motor is wired to match the
incoming voltage. All motors have a sticker near the
pressure switch that identifies the pre-wired voltage. All
½
hp jet pumps are factory wired for 115 V, and ¾
hp
and larger are wired for 230V. The motor voltage must
be changed inside the motor cover, not in the pres-
sure switch. Make sure the breaker or disconnect is OFF
before entering the motor cover. All motors have a wiring
diagram on the cover label and it is also found in this
manual.
See Motor Wiring Diagram, Fig. 7, in Technical
Data
.
BOOSTER SYSTEMS
Use the basic instructions for either a Shallow Well or Convertible with Shallow Well Adapter. If a city water booster
system please plumb per Fig. 5
J, JS, JRS OR HSJ SERIES
If pumping from a cistern or water tank plumb
per Fig. 6.

VALVE
Use flow control or ball valve
on suction to throttle pump. Must
be sized, or set, to load motor
below maximum nameplate amps.
Maximum inlet pressure should
be limited so discharge does not
exceed relief valve setting, or 100
psi (0.68Pa) absolute maximum.
