System pressure
The maximum permissible system pressure is stated on the pump
nameplate:
175 psi (12 bar).
Minimum inlet pressure
The following relative minimum inlet pressure must be available
at the pump inlet during operation to avoid cavitation noise and
damage to the pump bearings.

The relative minimum inlet pressures apply to pumps installed up
to 984 ft (300 m), above sea level. For altitudes above 984 ft
(300 m), the required relative inlet pressure must be increased by
0.145 psi / 0.01 bar / 0.001 MPa per 328 ft (100 m) altitude.
The MAGNA1 pump is only approved for an altitude of 6561 ft
(2000 m) above sea level.
EMC (electromagnetic compatibility)
EN 55014-1:2006, EN 55014-2:1998, EN 61800-3-3:2008 and
EN 61000-3-2:2006.
Sound pressure level
The sound pressure level of the pump is lower than 43 dB(A).
Leakage current
The pump mains filter will cause a discharge current to earth
during operation. I < 3.5 mA.
leakage
Power factor
The MAGNA1 has built-in PFC (Power Factor Correction) which
gives a cos φ from 0.98 to 0.99, i.e. very close to 1.
