Static Awareness 
Do NOT remove the rear cover - doing so will void your warranty. 
When the rear cover is removed the circuitry inside is exposed to 
possible damage by electrostatic discharge during handling.  
If Service is Required 
Contact Watlow Customer Service at (507) 454-5300 for instructions on 
how to return a product and how to obtain a Return Materials 
Authorization (RMA) number. 
Package the unit in its original packaging container or, if unavailable, 
any suitable rigid container. If a substitute container is used, surround the 
unit with shock absorbing material; damage in shipment is not covered 
by the warranty. Include a letter with the unit describing the difficulty 
and designating a contact person. 
All returns will be tested to verify customer claims of noncompliance 
with the product warranty. Improper return packaging, which makes 
verification impossible, will void the warranty. Products passing the tests 
will be returned “AS IS” to the customer. 
If noncompliance is verified and is not due to customer abuse or the 
other excepti ons described wit h product warranty, Watlow will, at its 
option, repair or replace the Product returned to it, freight prepaid, which 
fail to comply with the foregoing warranty, provided Watlow is notified 
of such noncompliance within the two-year warranty period.
