Ambient and liquid temperatures
UP(S)
The maximum allowable water temperature is
determined by the ambient air temperature as shown
in the table below.
Note: This table refers to all standard products without
timer, control options or other special features.
• If the UP pump is equipped with a timer, the
maximum liquid temperature is 150 °F (66 °C).
• Temperature requirements for pumps with timer,
control or other special features may be found on
their technical data page. See section Technical
data, pages 43-84.
The ambient temperature for standard pumps with a
permissible liquid temperature from 36 °F (2 °C) to 230
°F (110 °C) must always be lower than the liquid
temperature, as otherwise condensation may form in
the stator housing.

36 °F (2 °C) to 230 °F (110 °C).
To avoid condensation in the control box and stator,
the liquid temperature must always be higher than the
ambient temperature. In domestic hot water systems,
keep the liquid temperature below 149 °F (65 °C) to
eliminate the risk of lime precipitation.
Note: The maximum glycol concentration with clean
water is 50 % glycol @ 36 °F (2 °C). A hydraulic
performance change can be expected.
Maximum system pressure
145 psi (10 bar).
Minimum inlet pressure
The pressure required at the inlet of the pump is a
function of the temperature of the water as shown in
the table below.

Head range 0-46 ft (0-14 m)
In a pressure system, the required inlet pressure is the
allowable system pressure.
In a system open to the atmosphere, the required inlet
pressure is the minimum distance the pump must be
located below the lowest possible water level of the
water source (tank, pool, etc.).
