10. Technical data
10.1 Operating conditions
Supply voltage
1 x 115 V, + 10 %/- 10 %, 60 Hz.
Motor protection
The pump requires no external motor protection.
Enclosure class
Indoor use only, IP42.
CSA enclosure type 2.
Insulation class
F.
Relative humidity
Maximum 95 %.
Maximum outlet pressure
150 psi (10.34 bar).
Inlet pressure
Sound pressure level
43 dB (A).
Ambient temperature
32 °F (0 °C) to 104 °F (40 °C).
Liquid temperature
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.
Glycol
Maximum glycol concentrations with clean
water:
50 % glycol @ 36 °F (2 °C).
Hydraulic performance change can be expected.
Watt readings
Accuracy: ± 1 watt.
Flow indicator
Provides a relative indication of flow – should
not be used in lieu of a flow meter.
Check valve
Use of a check valve may reduce pump
hydraulic performance (up to - 10 %).
Use a check valve in parallel pumping
applications.
Curve conditions
Test liquid: Airless water.
Curves apply to a density of 983.2 kg/m
3
and a
liquid temperature of 140 °F (60 °C).
All curves show average values and should not
be used as guarantee curves. If a specific
minimum performance is required, individual
measurements must be made.
Curves apply to a kinematic viscosity of 0.474
cSt.

In domestic hot water systems, keep
the liquid temperature below 149 °F
(65 °C) to eliminate the risk of lime
precipitation.
