Safety Precautions - Liberty Pumps SumpJet SJ10 Manuel D'installation

Safety Precautions

RISK OF ELECTRIC SHOCK
WARNING
 Always disconnect any electric pumps from the power source
before handling, installing, or adjusting the SumpJet.
RISK OF SERIOUS INJURY OR DEATH
WARNING
 Sump water is non-potable. To reduce the risk of
contamination of the potable water supply, additional
backflow protection must be provided by the installer to
meet the requirements of the local plumbing code or the
requirements of the local water authority. As per the
Uniform Plumbing Code® and per the Plumbing Codes of
some states, including the State of Michigan, installation
of this product requires the use of an RP/RPZ (Reduced
Pressure/Reduced Pressure Zone) backflow protection
device. Contact your local plumbing or water authority for
more information regarding the requirements for your
specific area.
CAUTION
 The SumpJet is designed for use in clear water only. It is not
designed to remove waste water, sewage, effluent, or water
with debris in it.
NOTICE
 The SumpJet is designed for use with municipal water supply,
and is intended to be used as an emergency backup to an
existing pump system.
 The SumpJet comes with a foot valve installed and therefore
does not require a check valve on the discharge. The foot
valve has a removable poppet. Where freezing discharge
pipes are a problem, simply unscrew the strainer screen,
remove the poppet and spring, and replace the strainer. The
SumpJet will now allow water to flow back into the pit,
eliminating discharge pipe freezing.
 Maximum water pressure = 100 psi (690 kPa) with the valve
closed.

 Recommended minimum water pressure (ahead of backflow
prevention device) = 30 psi (207 kPa) with the valve open
(less pressure may not eject water from basement
adequately).
 For nominal backflow protection, the SumpJet is
pre-equipped with an internal check valve certified to ASME
A112.18.3 and ASME A112.18.1/CSA B125.1.
 Discharge of the SumpJet must not be connected to the
primary sump pump.
 Discharge of the SumpJet must not be directly connected to
the municipal drain.
 An air gap with a minimum 1" gap should be used, or the
discharge should be directed outside of the building, with the
end of the pipe between 150 and 610 mm (6 and 24 in) above
the ground or the flood level of the area receiving the
discharge.
 The inlet of the SumpJet is factory-equipped with a
SharkBite® push-type pipe connector. This fitting can be
used with various approved 3/4" potable water tubing and
pipe, such as PEX tubing (ASTM F876, CSA B137.5), copper
pipe (ASTM B 88), or CTS CPVC pipe (ASTM D 2846, CSA
B137.6). For more details on using the SharkBite, visit
www.sharkbite.com.
 Do not use paste-type sealant on inlet threads, and do not
sweat copper fittings within 18" of SumpJet body. Use PTFE
(Teflon®) sealing tape only when assembling threaded
fittings into SumpJet inlet. Do not overtighten threaded inlet
fitting, and do not hold onto float plunger shroud when
tightening.
 Purge water line prior to connection to SumpJet to ensure
debris does not enter unit and clog the operating valve.
 The SumpJet utilizes a quick-acting valve which, per UPC,
requires the use of an approved water pressure absorbing
device to prevent water hammer.
 Do not use SumpJet in water greater than 130 °F.
