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 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, the Manufacturer 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, the
Manufacturer will advise on the repair and recommend available service contractors.
C. It is of the utmost importance that you provide the correct model number and serial
number of the machine in question. This will allow the Service Department to obtain the
correct manufacturing records which will help to properly troubleshoot the problem and
obtain the proper replacement parts when they are required. This information is stamped
on the data tag that is attached to the electrical enclosure of each machine.
D. TheServiceDepartmentmustbenotiedpriortoanyrepairorserviceofawarranty
nature. Warranty claims will not be honored without prior authorization.
