Instructions for Returning Your Instrument for Service

The following information will help you return your instrument to Sierra Instruments' Factory Service Center and will ensure that your order is processed promptly. We will assign an RMA (Return Materials Authoriza- tion) number prior to the unit’s return and send you an estimate of charges within 24 hours of receiving your unit. Prices may vary depending on the flow range, type of gas and operating pressure of your unit. To request de- tailed pricing contact your local Sierra Instruments distributor or contact one of our offices directly. Our expedite fees are: three-day turnaround 25%, two-day turnaround 40%.

Please follow these easy steps to return your instrument for fac- tory service:

1.Obtain a Return Materials Authorization (RMA) number from Si- erra Instruments. You may obtain this from the factory by calling

(800)866 0200 between 8:00 a.m. and 5:00 p.m. PST Monday through Friday. You may also obtain this number via e-mail by contacting service@sierrainstruments.com.

2.Once you have obtained an RMA number, complete the form. If you require service beyond calibration, but do not know which service(s) will be required, describe the symptoms as accurately as possible on the RMA form. Submit electronically or by fax to

(831)373-2414.

3.Pack your instrument carefully (bubble wrap or molded foam sug- gested-NOT PEANUTS) and include a copy of the RMA form (complete with Sierra supplied RMA number) with the unit(s).

Ship the unit(s) to the following address:

Caution! Always fully neutralize

any toxic gas trapped in-
