6. The lid assembly will disengage the pump body
after approximately 45 degrees of rotation.
7. Inspect the O-ring located in the lid for debris
or damage. See Figure 9. If necessary, insert a
flat head screw driver through the notch to assist
in removing the O-ring. If there is any evidence
of degradation, debris impregnation, or tearing
of the O-ring, replace the seal immediately. Use
only silicone based O-ring lubricants to assist in
assembly.
8. The strainer basket may be removed and emptied.
Ensure the basket is lined up properly with the
strainer's inlet port when placing the basket back
into the strainer pot. See Figure 10.
9. To reassemble the lid, align the arrows that indicate
"Port" approximately 45 degrees counterclockwise
from the inlet port. Turn the lid clockwise until
the lid engages the pump body and the handles are
perpendicular to the ports. The arrows will align
with the ports. Install the lid's center plug and seal.
Note: The lid
and locking ring
seal assembly
will disengage
together. To
remove the
lid from the
assembly, align
the lid's 3 lifting
tabs with the
notches in the
locking ring and
carefully push
the lid out.

Pressure Testing, Strainer Pot

Certain local codes require that the circulation system be
pressure tested with a proof pressure before being
commissioned into service or before allowing
construction to progress to the next stage.
This strainer pot is intended to operate on the suction
side of the pump and must not be installed on the
pressure side of a circulation system. Extreme caution
should be taken when applying pressure to this
product during a system pressure test. Exceeding the
pressure or temperature rating during the pressure
test can result in a structural failure. A structural
failure of the strainer pot assembly can cause the
instantaneous release of energy causing failed
components to be accelerated to high velocities
and to travel distances of 30.5 m (100 feet) or more.
These components could cause severe personal
injury or death if they were to strike a person.
It is important that the lid and locking ring are in the
closed position before performing a pressure test.
Instructions engraved on the locking ring show the
locked position when the ports are in line with the
arrows with the word "port" engraved on the locking
ring. If the lid and locking ring are not installed and
in the correct position a structural failure can occur
causing sever personal injury or death.
Improperly pressure testing a circulation system can
involve significant risk of property damage or severe
personal injury or death. Circulation systems store
energy when pressure tested due to the elastic nature
of the materials used in construction and due to the
compressibility of air that may be contained in the
system. The instructions below should be considered
a guide only. Each installation should be considered a
unique situation that should be carefully investigated
for risk.
Never test this equipment with air pressure even if
specified by the local code. Even low levels of air
pressure result in tremendous storage of energy that
can instantaneously be released if a system failure
occurs. This instantaneous release of energy can
cause failed components to be accelerated to high
velocities and to travel distances of 30.5 m (100 feet)
or more. These components could cause severe
personal injury or death if they were to strike a person.
