NOTE
Placing the ALARM LIMIT (PPM) SELECTOR Switch A1S2 in the 15 PPM or 70 PPM
position disables the Remote Indicator Assembly.
8. If the Remote Indicator Assembly (figure 6) is not used, set the ALARM LIMIT (PPM) SELECTOR Switch A1S2
(figure 4, item 2) to the 15 PPM position for OWS operation within 12 nautical miles of land or the 70 PPM
position for OWS operation outside 12 nautical miles of land. To utilize the Remote Indicator Assembly, set the
ALARM LIMIT (PPM) SELECTOR switch A1S2 to the REMOTE position.
! CAUTION
The OCM must have flow through it while in operation. Operating the OCM without flow
through it for more than 2 minutes will result in damage to the OCM. Failure to comply
with this caution will result in damage to the equipment.
9. Set the OWS control panel switch (figure 1, item 1) to MAN. The OWS pump will start, drawing oily water
through the unit. The pump will continue to run as long as the switch is in the MAN position.
10. Verify that the OCM has fluid flowing through the OCM sample inlet tubing (figure 4, item 3) and is discharging
fluid through the OCM sample discharge tubing (figure 4, item 4). If the OCM does not have fluid flow within 2
minutes, turn the OWS control panel switch (figure 1, item 2) to OFF and notify the maintenance supervisor. If
the OCM does have fluid flow within 2 minutes continue with the procedure.
11. Close and secure the sampling/sensor assembly door (figure 4, item 5).
