Operation Testing; Maintenance - Little Giant OS3 Series Owner's Manual

OPERATION TESTING

1. Plug the pump's power cord into the control panel outlet cable.
2. Test the high-oil circuit.
• Lift the float switch with the sump empty of water.
• Oil is non-conductive, and when the float is lifted only the High Oil indicator will be illuminated.
• The auxiliary contacts in the control panel and the remote alarm will activate.
3. Test a pump cycle.
• Make sure the discharge plumbing is directed correctly.
• Slowly fill the tank with water until the water reaches the cen-
ter START probe.
• Make sure the pump turns on and operates until the water
level falls below the OFF probe.
• Check the discharge plumbing for leaks.
4. Test the high-water circuit.
• Unplug the pump from the control panel.
• Slowly fill the tank until the water level reaches the alarm
probe.
• Make sure the High Water indicator illuminates.
• Verify that the auxiliary contacts in the control panel activate the remote alarm.
5. Test the remote alarm for power loss.
• Unplug the power cord on the control panel.
• The auxiliary contacts should close and the remote alarm should activate.
6. Test the alarm panel.
• Verify the green power light is on.
• Press Alarm Test and make sure the red alarm light and buzzer
turn on.
• While holding Alarm Test, press Alarm Silence. Make sure the
buzzer turns off, but the alarm light remains on.
• Release Alarm Test so the alarm light turns off and the green
light turns on again.
7. If used, test the battery backup system.
• Unplug the wall-mounted power supply.
• Make sure the green light turns off and the pump continues running.
8. Press Alarm Test to make sure that the red alarm light and buzzer turn on.
• If the buzzer sounds quieter than with the normal power supply, replace the battery.

MAINTENANCE

• Clean the preset level control with alcohol to ensure it remains free of rust, mud, soap or any con-
ductive material.
• Clean the probes yearly, keeping them free of debris, calcium, or iron deposits.
• Replace the alarm panel's 9 VDC battery yearly.
• When replacing fuses in the control panel, use 5mm x 20mm 1/2-amp for F1 and 5mm x 20mm
1-amp for F2.
