Preventive Maintenance and Troubleshooting Guidelines for

Class 9013F and 9013G Pressure Switches

Retain for future use.

Introduction This data bulletin describes how to identify and correct the most common

maintenance issues for the Class 9013F and 9013G Pressure Switches.

Ensure that all maintenance recommended by the original equipment

manufacturer (OEM) is performed. If the equipment fails to operate properly,

refer to the instructions and recommendations provided by the OEM, and

ensure that the instructions were correctly followed. If the operating

problems persist and a pressure switch is the suspected cause, use the

information in this bulletin to assist in troubleshooting the issues.

Inspecting the Pump System

Before the Initial Operation Inspect the following items before operating the pump system:

1. Check the pump’s yield and flow rate.

2. Check the well water level, drawdown, and recovery.

3. Check the line voltage with the pump on and off.

4. Verify that the running current does not exceed the motor nameplate

data.

Before Maintenance Inspect the following items before performing maintenance to the pump

system:

1. Visually inspect the pump system for leakage.

2. Check the pressure switch using a pressure gauge.

3. Record the pressure switch setting if available.

4. Review any system discrepancies or perceived problems in operation.

5. Confirm that electrical power is available and that circuit breakers (or

fuses) are operational.

Providing Routine Maintenance During the normal maintenance period for the pump system, ensure that the

following steps are followed to for all pressure switches.

1. Disconnect the power.

2. Remove the cover.

3. Visually inspect the pressure switch for leakage. Verify that:

— No liquid is leaking from the diaphragm or flange area.

— The flange is not corroded.

— The area is free of standing water and wet spots.
