REPAIRS
A
fter final installation of the TS Series Digital Temperature Switch, no routine
maintenance is required. A periodic check of system calibration is recom-
mended. The devices are not field repairable and should be returned to the
factory if recalibration or other service is required. After first obtaining a
Returned Goods Authorization (RGA) number, send the material, freight pre-
paid, to the following address. Please include a clear
description of the problem plus any application information
available.
