Special Note for Canadian Installations
An O-Ring is used on the shaft in Canadian installations. If squealing is noted, lubricate the O-
Ring with silicone grease. When replacing a meter, align the lower drive collar to the meter
shaft to reduce the potential for binding.
Service Tips
• During shipment, T18350-G3 pulsers are restrained by a tie-wrap and should be removed
during installation. If the tie-wrap is discovered on the pulser during a service, it should be
removed. A tie-wrap left in place can result in binding of the pulser shaft.
• Event Logs can be used to identify a specific pulser during troubleshooting pulser errors
such as 20, 5047, 5049 and 5050. Pulser locations are designated by ePulserX. Refer to the
following table to determine the location of the pulser.
Note: Event Logs are available only for Atlas 8800 units.
