INSTALLATION, OPERATION
AND CLEANING
Refer to the Installation & Operation Manual for
specific instructions.
NOTE: Daily cleaning is required.

INTRODUCTION

Features


Requires no water or drain line connections
(manual fill & manual drain)

Cast aluminum "element block" for efficient
heat transfer and distribution

Field convertible to single phase or three
phase power

When wired for single phase, a reduced 2/3
power output is available

Steam Cooking

The VPX series steamer provides timed or
continuous mode cooking in a "pressure-less"
compartment. The small physical size of the
steamer offers an efficient way to produce many
foods in small batches. Pressure-less, convection
steam cooking will steam cook fresh foods or will
steam defrost and cook frozen foods providing the
maximum color, flavor and nutritional value with the
least expenditure of energy and labor. The
"pressure-less" cooking compartment allows the
operator to open and close the door, anytime during
a cooking cycle.
