SEASONAL SERVICE
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.

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.
If pumping from a cistern or water tank plumb
per Fig. 6.
