SCOT
INSTALLATION
INCLUDES
Check pump for shortage and damage immediately upon
arrival. Note damage or shortage on freight bill (bill of
lading); immediately file claim with carrier.
EXTERIOR
— Pay particular attention to conduit box,
external hardware and accessories. Touch up abrasions
or scratches with approved paint.
INTERNAL
— If extensive or serious external damage
is noted, if impeller is damaged (look in ports), or if shaft
binds or sticks, disassemble as required to permit
internal inspection.
HANDLING
Handle with care. Dropping or jarring can seriously
damage motor bearings or break pump parts. Lift with
device having capacity for pump weight, and use lifting
hooks or eye bolts (if provided) or rig double sling around
motor frame and pump casing. Do not use sling through
pump motor adapter nor around suction and discharge
flanges.
INSTALLATION
Location
— Pump location should provide the
following:
1. Install as close to suction supply as possible.
2. Shortest and most direct suction pipe practical.
Suction lift must not exceed limit for pump. NPSH
available must equal or exceed pump requirement.
3. Suction port below pumping level to provide priming.
4. Room for inspection and maintenance.
5. Correct power supply to motor; all wiring should
meet National Electrical and Local Codes and
Regulations.
6. If outdoors, protection from the elements, freezing
and water damage due to flooding.

Piping
— Suction and discharge gauges are useful to
check pump operation and are excellent trouble
indicators. Install gauges in the lines if pump ports do not
have gauge taps. Observe these precautions when
installing piping:
1. Support close to, but independently
of pump.
2. Use the next larger pump size for suction
and discharge.
3. Keep as straight as possible. Avoid bends
and fittings.
4. Remove burrs, sharp edges, ream pipe cuts, and
make joints air-tight.
5. Don't spring pipe to make connections.
Strain must not be transmitted to pump.
6. Allow for pipe expansion with hot fluids;
expansion joints are not recommended.
Suction
— Size and install suction piping to keep
pressure loss at minimum and to provide correct NPSH
by observing the following:
1. The suction pipe should be equal in size or
preferably one size larger than the suction
connection of the pump. If pipe is larger than the
pump suction, an eccentric pipe reducer should be
used at the pump.
2. Pipe should slope upward to pump, even for
horizontal run.
3. Use 45-degree or long-sweep 90-degree elbows.
4. A valve in the suction is necessary only on positive
suction head installation and must not be used to
throttle the pump. The suction valve should be
installed for maintenance purposes only.
