5.1 WARRANTY SERVICE PROCEDURE
A. In the event of a problem with a chiller that can not be resolved by
normal troubleshooting procedures, the customer is invited to
consult the Conair service department for assistance. The correct
model number and serial number of the chiller must be available.
The service department will attempt to isolate the problem and
advise repair procedures. Often times, with the customer’s input
and with the machine diagnostics, problems can be determined
with “over-the-phone” consultation.
B. If the problem is beyond the scope of “over-the-phone”
consultation, and if the warranty status of the machine is valid,
Conair will contact the nearest authorized service contractor and
provide authorization to conduct an “on-site” inspection of the unit
in order to determine the course of repair. If the chiller is not
covered by the warranty, Conair will advise on the repair and
recommend available service contractors.
C. Conair manufactures a complete line of heat transfer equipment. It
is of the utmost importance that Conair have the correct model
number and serial number of the machine in question. This will
allow Conair to obtain the correct manufacturing records which
will help the service department to properly troubleshoot the
problem and obtain the proper replacement parts when they are
required. This information is stamped on the metal data tag that is
attached to the machine.
D. The Conair service department must be notified prior to any repair
or service of a warranty nature. Warranty claims will not be honored
without prior authorization.
