4.1 Pre-installation
Precautions
WARNING:
•
When installing in a potentially explosive environment, ensure that the motor is properly
certified.
•
All equipment being installed must be properly grounded to prevent unexpected dis-
charge. Discharge can cause equipment damage, electric shock, and result in serious in-
jury. Test the ground lead to verify it is connected correctly.
NOTICE:
•
Electrical connections must be made by certified electricians in compliance with all inter-
national, national, state and local regulations.
•
Supervision by an authorized ITT representative is recommended to ensure proper instal-
lation. Improper installation may result in equipment damage or decreased performance.
4.1.1 Pump location guidelines
Guideline
Explanation/comment
Keep the pump as close to the liquid source as prac-
tically possible.
This minimizes the friction loss and keeps the suction piping
as short as possible.
Make sure that the space around the pump is suffi-
cient.
This facilitates ventilation, inspection, maintenance, and
service.
If you require lifting equipment such as a hoist or
tackle, make sure that there is enough space above
the pump.
This makes it easier to properly use the lifting equipment and
safely remove and relocate the components to a safe loca-
tion.
Protect the unit from weather and water damage due
to rain, flooding, and freezing temperatures.
If the possibility of freezing exists during a shutdown
period, then drain the pump completely and use com-
pressed air to blow out all passages and pockets
where liquid might collect.
This is applicable if nothing else is specified.
Do not install and operate the equipment in closed
systems unless the system is constructed with prop-
erly-sized safety devices and control devices.
Acceptable devices:
•
Pressure relief valves
•
Compression tanks
•
Pressure controls
•
Temperature controls
•
Flow controls
If the system does not include these devices, consult the en-
gineer or architect in charge before you operate the pump.
Take into consideration the occurrence of unwanted
noise and vibration.
The best pump location for noise and vibration absorption is
on a concrete floor with subsoil underneath.
If the pump location is overhead, undertake special
precautions to reduce possible noise transmission.
Consider a consultation with a noise specialist.
