9.1 Operating conditions
9.1.1 Liquid temperature
For UP(S) Series 15 pumps with power cable
only
The maximum allowable water temperature is
determined by the ambient or surrounding air
temperature as shown in this table:
Although the pump is designed to operate at a
maximum water temperature of 230 °F (110 °C),
we recommend that you keep the operating
temperature as low as possible (i.e. below 140
°F (60 °C) to avoid precipitation of calcium.
See exceptions in section
.
9.1.2 Inlet pressure
The pressure required at the inlet of the pump is
a function of the temperature of the water as
shown in this table:
In a pressurized system, the required inlet
pressure is the minimum allowable system
pressure.
In an open system, the required inlet pressure is
the minimum distance at which the pump must
be located below the lowest possible water level
of the water source (tank, etc.).
