2. After the cable-sling is attached to the
lifting lugs (lifting eyes) on the pump head,
raise the pump to a vertical position. While
in this position, install the strainer basket
with bolts and clips. Position the pump
over its access hole on the skid.
WARNING: Falling Objects Hazard
DO NOT work under heavy suspended object
unless there is positive support and safeguards
should a hoist or sling fail.
Failure to follow these instructions could result in
serious personal injury, death, or property
damage.
3. Very slowly, lower the pump through its
access, keeping one hand on the pump to
detect any bumping by the pump against
the edge of its hole or the wall of the wet
well. When the pump is properly installed,
it should not touch the side of the wet well.
Premature bearing failure or destruction of
the bowl assembly can result from
improper installation.

Hole on Skid
WARNING: Equipment Damage Hazard
Be prepared to stop lowering the pump
IMMEDIATELY if any bump is felt.
It is possible that the pump bowl could catch on
the edge of the skid and become unhooked from
the cable or other lifting device. Possible serious
bodily injury or damage to the pump could result.
Verify and ensure that the safety latch on the hook
works properly.
Failure to follow these instructions could result in
serious personal injury, death, or property
damage.
4. Push the pump slightly off-center when it
is being lowered in the wet well to avoid
hitting the manifold discharge pipe.
5. Stop lowering the pump when the base of
the head is approximately 1/8 to 1/4 inch
above the platform.
