These pumps come with wire leads that are either 14, 16, or 18 AWG (2.5mm
2
, 1.5 mm
2
, or 1 mm
2
). The wire
gauge can be found printed on the leads. Below is a guide to use when extending the wires. Do not use a
smaller diameter wire than the pump’s leads.

Operation
Ensure that the intake side of the line connected to the pump inlet is submerged in water. With power on
and the discharge line open, allow the pump to prime. If equipped with an on-demand pressure switch the
pump will turn on when the discharge line is open and will turn off once the line is closed and the switch off
pressure is reached. When finished, manually turn off the power to the pump. Note that the pump is intended
for intermittent duty only. If allowed to overheat the thermal protection will shut it off until sufficiently
cooled, at which point it will automatically re-set.
Maintenance
During Season
Periodically (monthly recommended) check electrical connections, hydraulic connections and plumbing
for looseness, any signs of damage, or anything else unusual. Inspect strainer as well and clean as needed.
Off-Season & Winterizing
Properly drain unit by removing the intake line from the fluid and running the pump until it is no longer
dispensing fluid. Winterize the unit (if in environment where temperatures will go below freezing) with an
appropriate anti-freeze by running the unit so as to fill with anti-freeze. Do not allow any fluid in the pump to
freeze. If this occurs the fluid will expand and can crack the pump or damage internal components.
