8.1.2 After Installation into piping
• Carefully open shuto valves and check for leaks.
• Make sure that the electrical box cover is mounted and that all cable glands are installed to prevent
dust and particles from contaminating the electrical box.
• Before starting the pump, the system (and pump) must be lled with uid, and air completely bled out
of the system. For proper operation, pressure must be maintained on the suction side of the pump.
The pump does not have screws for bleeding the air, as it is automatically bled as a function of the design
of the pump. Temporary air in the pump will generate noise that disappears after a short time.
• Extended periods of dry running will activate an E10 low motor load error and in most cases reduce
or eliminate sleeve bearing damage caused by dry run conditions
WARNING!
• The maximum system pressure is 175 psi (1MPa or 12 Bar)
• The pump must always be lled with system uid as it is water lubricated and water cooled
• The motor stator openings (condensate drain holes) and stator housing should not be insulated since
the thermal insulation may prevent motor cooling and prohibit condensate from escaping from the
motor housing when used in high humidity environments where the uid temperature is below
the motor temperature.
