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. Horizontal 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 IN-
STALLING 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 motor
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 pressure
switch. Make sure the breaker or disconnect is OFF
before entering the motor cover. All motors have a wir-
ing 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
If pumping from a cistern or water tank plumb
per Fig. 6.
