primed. A "pitless adapter" may be optimum for freeze protection. Check with your local well
supplier for details.
POLYETHYLENE PIPE comes in rolls, and is inexpensive and quite freeze-tolerant. Use with
plastic adapters and secure with ALL-STAINLESS hose clamps (obtain such clamps from a pipe
supplier rather than automotive supplier). If pipe does not stretch tightly over fittings, warm it
with a torch or hot water then tighten clamps firmly with a wrench. Use two clamps at each joint.
Keep extra clamps handy in case you strip one.
ELECTRICAL WIRING
WIRE SIZING: DON'T CHEAT YOURSELF with undersized wire! Your pump is wired with a
short length of #14 or #12 cable. This size is sufficient for short lengths only. Splice it to a
larger size of wire if your wire run is longer than 15 feet. Consult a low voltage wire size chart or
call your dealer or the factory for recommendations. Excessive voltage drop will slow the pump
down, but if it is unavoidable, don’t worry. It will NOT cause any harm to the motor.
BLACK WIRE = POSITIVE (+) WHITE WIRE = NEGATIVE (-) GREEN WIRE = GROUND
1400 & 2600-Series Slowpumps: Red = Positive Black = Negative
Reverse polarity will cause reverse rotation. This will not cause damage if done for a short time.
Reverse the wires if necessary so pump turns CLOCKWISE looking at the red face of the pump.
FUSE OR CIRCUIT BREAKER PROTECTION
FAILURE TO INSTALL A FUSE OR BREAKER equal to or less than
the motor's Max Amps rating WILL VOID YOUR WARRANTY.
If water flow becomes blocked, or if the pump jams or freezes and cannot turn freely, the motor
will draw excessive current. A fuse or circuit breaker will then break the circuit. Without such a
"safety valve", a minor fault can burn your motor and wiring.
Install a fuse or breaker with an AMP RATING close to the "MAX AMPS" rating of your motor,
OR LESS (but not more higher). If a Linear Current Booster is being used (for array-direct
Slowpumps) install the fuse between the booster and the pump. Use the rating recommended
for the booster or for the pump, WHICHEVER IS LESS. This fuse will protect the booster as
well as the motor and wiring from overload.
FUSES: Use a “time-delay” type. The 3" paper cartridge type is good, and may be installed into
a raintight disconnect switch available at any electric supplier. An automotive in-line fuse holder
is fine for 12 or 24V systems. Automotive blade fuses (type ATC) are prefered over glass fuses.
They have sufficient time-delay. (Time-delay glass fuses are available from ELECTRONIC
suppliers only, not automotive.) Use good quality fuse holders, protected from weather. Keep
spare fuses handy. Never substitute a larger fuse!
CIRCUIT BREAKERS: Most AC breakers cannot be used for low voltage DC circuits. We
recommend only the SQUARE-D® QO or QB-series which been rated safe up to 48 volts DC. A
10 amp size is available, but not in most stores. It may be ordered from your PV dealer or from
an electric supplier.
