INSTALLATION & OPERATION MANUAL
INSTALLATION PREPARATION
The goal of installation is to provide a
quiet, easy-to-maintain installation with
good flow and low backpressure. This
can be accomplished with the following
guidelines:
❚ Mount on a solid surface in an
accessible location for strainer cleaning
and pump maintenance.
❚ 1/2" Male threaded models are intended
to be used with SHURFLO swivel barb
fittings which seal with an internal taper
when hand tightened. CAUTION: Sealers
and Teflon tape may act as lubricant
causing cracked housings or stripped
threads due to over-tightening. Sealer
may enter the pump inhibiting valve
action, causing no prime or no shut-off. A
failure due to foreign debris is not covered
under warranty.
❚ Use flexible high-pressure hose on the
pump inlet and outlet [such as SHURFLO
Kit 94-591-01]. The pumps ports and
strainer should not be connected to
plastic or rigid pipe, or the pump's
normal motion will transmit through rigid
plumbing causing noise, and possibly
loosening or cracking components.
MOUNTING
❚ Mount the pump within 6 feet of the
tank for best performance and pump
life. The pump will pull farther, but the
farther it pulls the more work it does,
increasing vibration and noise, and
reducing the output and pump life.
❚ Mount pump in a space of at least 1
cubic foot for adequate ventilation to
prevent overheating.
❚ Pump may be mounted in any position.
❚ Mount pump for easy access for
cleaning strainer, maintenance and
service.
❚ Mount pump on a solid surface to
prevent vibration and noise.
INSTALLATION GUIDELINES
❚ Solid Surface within 6' of tank.
❚ Minimize flow restrictions in the
system.
❚ No Accumulator needed.
❚ Flexible hose on inlet and outlet.
❚ Minimize plumbing elbows and valves.
❚ Accessible location.
❚ Strainer on pump inlet.
❚ Properly Sized wiring.
❚ Properly electrical protection.
❚ Properly sized plumbing.
❚ Pump must use an adequate 50-mesh
strainer [such as SHURFLO 255 series
strainers].
❚ Use a minimum of 1/2" [13mm]
Inner Diameter plumbing. Smaller ID
plumbing will cause cavitation, high
back pressure, low flow and noise.
❚ No need for an accumulator with by-
pass pumps.
❚ Pump is designed for intermittent
duty only: Do not use these pumps
for running a Reverse-Osmosis [RO]
Filtration System. High pressure-
continuous duty usage will shorten
the life of the pump and is not covered
under warranty.
❚ Wire Size is 16 GA MINIMUM, 12GA
is recommended —See Wire Chart in
Electrical Section for minimum sizing.
❚ Minimum power requirement is a 10
Amp circuit.
❚ Reduce restrictions on inlet and
outlet. This includes small inner
diameter shut-off valves, winterizing
valves and elbows.

Typical Pump Installation
❚ If the RV has an Intellitec Pump
Controller, it must be rated at 10 or 15
amps; If the controller is rated at 7.5
Amps, a new controller or a high-amp
relay must be used.
