Precautions
WARNING:
• Observe accident prevention regulations in force.
• Use suitable equipment and protection.
• Always refer to the local and/or national regulations,
legislation, and codes in force regarding the selection of
the installation site, plumbing, and power connections.
4.1 Pump handling
WARNING:
Observe local codes and regulations setting the limits for
manual lifting or handling.
Always lift the pump by the motor housing or pump body. If the pump
weight exceeds the manual handling limits, use lifting equipment with
lifting straps.

4.3 Facility requirements
4.3.1 Pump location
DANGER:
Do not use this unit in environments that may contain flam-
mable/explosive or chemically aggressive gases or powders.
Guidelines
Observe the following guidelines regarding the location of the prod-
uct:
• Make sure that the installation area is protected from any fluid
leaks, or flooding.
• If possible, place the pump slightly higher than the floor level.
• Provide shut-off valves on the suction and discharge sides of the
pump.
• The relative humidity of the ambient air must be less than 95%
non-condensing.
• This pump is suitable for indoor use only.
CAUTION:
CAUTION: PROPERTY DAMAGE HAZARD. It is not advisable
to install circulators in an attic or upper floor over finished liv-
ing space. If the circulator must be installed over head, or
over expensive equipment, provide adequate drainage in
the event of leakage. Failure to follow these instructions
could result in property damage.
4.3.2 Minimum inlet pressure at the suction port
The values in the table below are the inlet pressures above the atmos-
pheric pressure.
Nominal Suction Fluid tempera-
Diameter ture 77°F (25°C)
1½" 4.5 PSI
2" 4.5 PSI
3" 7.5 PSI
NOTICE:
• Ensure that the suction pressure is never below the values speci-
fied above, as this could cause cavitation and damage the pump.
• The inlet pressure plus the pump pressure against a closed valve
must be lower than maximum admissible system pressure.
4.3.3 De-rating table
The following table indicates percent decrease in input power draw,
with the increase in temperature of circulating water and the ambient.
