Continuous purge: The purge line valve is open a small amount and water
continuously purges the system to keep it clean.
Note: It is recommended to purge the unit while in operation. This assures a strong
purge for best evacuation of the solids collection chamber.
Winter Operation: If exposed to freezing temperatures, the potential exists for the
separator and related exposed piping to freeze. Damage to piping and separator
may result. Continuous operation will minimize the freeze risk however, it is
recommended to protect the piping and separator in some manner (locate indoors or
apply heat tracing and insulation to exposed all surfaces). If the unit is idle for
periods of time, it is recommended to drain the ICS Separator and pump.
Startup Procedure:
Before startup, always check the immediate area and remove any debris that may
interfere with moving pump parts or cause possible injury to personnel.
If the unit is supplied with the optional system matched pump / pre-strainer
combination, check the pre-strainer basket prior to every startup for large solids that
may damage ~ pump or restrict it's flow.
With power turned off and locked out at the main circuit breaker, turn the pump
shaft by hand to make sure that the impeller turns freely.
Check any isolation or service valves to make sure they are in the full open position
so as not to restrict the suction or discharge.
Quickly turn the pump motor on and then off, taking note of the rotation of the
pump shaft. Make sure the shaft is rotating in the direction required by the pump.
If the motor rotates backward, have an electrician switch the phases and repeat this
procedure.
Open the manual air relief valve on the top of the separator. Start the pump and
allow the separator vessel to fill. Once the air is purged, close the valve.
Check the pump motor current draw to make sure it is not drawing more than the
rated current. Refer to the motor nameplate for the current rating and voltage
requirement.
Check the system piping and repair any leaks. Open the air vent again on top of the
separator. If air is vented, it could be caused by a small leak in the pump inlet
