FACTORY SERVICE POLICY
Your Digital Glycol Feeder (DGF) is designed to make-up lost glycol in a closed loop system. If
you are experiencing a problem with your DGF consult the trouble-shooting guide. If the
problem is not covered or cannot be solved, please contact your local Pulsafeeder Representative
or our Technical Service Department at [phone] for further assistance.
Trained individuals are available to diagnose your problem and arrange a solution. Solutions may
include purchasing a replacement unit or returning the DGF to the factory for inspection and
repair. All returns require a Return Material Authorization (R.M.A.) number to be issued by
Pulsafeeder. Pulsafeeder personnel may credit replacements purchased under a possible warranty
situation after an examination of the original parts.
Certain components may be purchased for replacement. Pulsafeeder personnel may credit parts
purchased to correct a warranty issue after examination of the original parts. Parts returned for
warranty consideration that test satisfactorily will be sent back to the originator freight collect.
Any field modifications will void the Pulsafeeder Digital Glycol Feeder warranty. Out-of-
warranty repairs will be subject to Pulsafeeder's standard bench fees and testing costs
associated with replacement components.
