UNBOXING AND INSPECTION
Unbox and handle with care.
Inspect unit for damage and report all damage to
carrier immediately.
Hazardous suction. Can trap hair or body
parts, causing severe injury or death.
Do not block suction.
INSTALLATION
PIPING - GENERAL
• Piping MUST be installed horizontally on a solid flat
surface, with discharge on top.
• Allow adequate space for servicing and ventilation
with strainer. Protect unit from weather and water
damage due to rain or flooding or freezing
temperatures.
• Piping should be no smaller than the suction and
discharge connections and kept as short as possible,
avoiding unnecessary fittings to minimize friction
losses.
• All piping MUST be independently supported and
MUST NOT place any piping loads on the pump.
• Use hex nut and bolt (Repair parts # 5 & 6) to level
strainer with pump suction during installation. DO
NOT cantilever strainer off pump suction – use hex
nut and bolt to prevent unnecessary strain on pump
suction.
NOTICE: DO NOT FORCE PIPING INTO PLACE AT
PUMP SUCTION AND DISCHARGE CONNECTIONS.
• The use of Teflon™ tape, or equivalent, is
recommended for ALL piping joints.
• All pipe joints MUST be airtight.
• Total suction lift, including elevation and pipe friction
losses should not exceed 25 feet.
• For lifts longer than 10 feet, a foot valve or check
valve must be used in the suction piping.
STRAINER TESTING AND OPERATION
Before removing strainer cover:
1. SHUT OFF pump before starting
2. CLOSE ALL VALVES in suction and discharge
piping.
3. RELEASE ALL PRESSURE from pump and piping
system
4. Hydrotest pump and strainer assembly to ensure
strainer was installed and attached to pump
correctly.
MAXIMUM HYDROSTATIC TEST
PRESSURE IS 20 PSI WATER PRESSURE
After hydrostatic pressure test, release all
pressure in the system before removing
strainer cover.
• To avoid damaging the pump or putting
unnecessary strain on the pump and/or strainer/
support pipe independently of the pump/strainer.
• Center the cover on the strainer body when
installing.
• When installing the cover, clean O-Ring groove in
strainer body and lubricate the following surfaces
with petroleum jelly.
1. O-ring
2. Sealing surfaces of the strainer cover and body
3. Threads and faces of wing nuts
• Lubricating these surfaces will prevent corrosion,
provide a better seal, and improve ease of
maintenance.
• Hand tighten lock handles, alternating back and
forth between handles to ensure even compression;
hand tighten only.
• Use a wrench on the handle flats if necessary to
remove cover.
NOTICE: A clogged suction strainer will impact
performance and eventually cause cavitation. Clean
and empty strainer basket on a regular schedule to
prevent clogging.
