4 Installation
4.1 Pre-installation
Equipment that will operate in a potentially explosive environment must be installed in accordance
with the following instructions.
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
practically 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 serv-
ice.
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 location.
Protect the unit from weather and water damage
due to rain, flooding, and freezing temperatures.
This is applicable if nothing else is specified.
Do not install and operate the equipment in closed
systems unless the system is constructed with
properly-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 engi-
neer or architect in charge before you operate the pump.
Take into consideration the occurrence of unwant-
ed 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.
