INTRODUCTION

A good preventive maintenance program begins with the daily cleaning procedure.  Additional
preventive maintenance operations are presented in this section.  In establishments that
employ full-time maintenance personnel, the tasks described can be assigned to them.  For
other installations, tasks requiring mechanical or electrical experience should be performed by
an authorized service agency.

The following paragraphs are set out for minimum preventive maintenance procedures that
must be completed periodically to assure continued trouble-free operation of the steamer.

CAUTION:  Under no circumstances should hardware (or parts) be
replaced with a different length, size, or type other than as specified
in the parts list.  The hardware used in the cooker has been selected
or designed specifically for its application, and the use of other
hardware may damage the equipment and will void any warranty.

WARNING:  Disconnect the power supply to the appliance before
cleaning or servicing.  

WARNING:  The steamer and its parts are hot.  Use care w hen
operating, cleaning or servicing the steamer.  The cooking
compartment contains live steam.  Stay clear when opening door.
