Troubleshooting Guide

This Robinair pump has been designed for dependable use and long life. If something should go wrong, however, the following guide will help you get the pump back into service as quickly as possible. 

If dis-assembly of the pump is required, please check your warranty. The warranty may be voided by misuse or customer tampering that results in the pump being inoperable.

Check line voltage. Robinair pumps are designed to start at +10% line voltage (loaded) at 32o F. At extremes, however, switching between the start and run windings may occur. 

1. Verify the oil is not a residual accumulation from spillage, etc.

2. If leakage exists, the module cover gasket or the shaft seal may need replacing. Follow the instructions supplied with Seal Replacement Kit No. 15367. If leakage exists in the area of the oil drain plug, you may need to reseal the plug using a commercial pipe thread sealer.

1. Verify the Iso-Valve™ on the pump is in the OPEN position.

2. Verify the vacuum gauge and all connections are in good conditon and leak-free. Confirm leakage by monitoring the vacuum with a thermistor gauge while applying vacuum pump oil at connections or suspected leak points. Vacuum will improve briefly while the oil is sealing the leak
