Installation
The steamer should be installed in a well-
ventilated room. The steamer must be
securely fastened to a table or moveable
cart that is capable of handling the weight
of one or multiple steamers. Each Steam
and Hold weighs approximately 200
pounds and the total weight capacity
requirements of the cart or table must be
considered prior to installation. 3X safety
factor recommended. I.e. 1 Steam and
Hold (200 lbs) x 3 S.F. = 600 lbs minimum
weight load capacity per work surface.
NOTE: Installer MUST verify the weight
restrictions of the table, cart, or
service rack prior to installation
of the steamer. All warranties
will be VOID if work surface is
unabletohandlethespecied
weight load.
The steamer must be installed on a level
surface. The Steam and Hold has built-in
water level controls requiring the surface
to be parallel to the horizon. The steamer
must be level front-to-back or pitched
slightly backwards for the cavities to drain
properly.
Install steamer with at least 6 inches
of clearance from the back wall. Side
clearances of at least 6 inches are
recommended. Antunes recommends
enough clearance for easy cleaning,

Water Supply Quality
The quality of the water supply to the boiler
is important for proper operation. Low
hardness water will keep the boiler cleaner
and reduce the need for frequent clean
cycles.
It is recommended that the water quality
conditions in this documents be met.
An Antunes Water Treatment System is
recommended to best attain these water
conditions. Consult Antunes Customer
Service for more information on and
Antunes product that is designed for the
Steam and Hold.
NOTE: Failure to follow these water
quality conditions will VOID the
warranty and may cause the
steamer to operate erratically or
fail prematurely and require a
service call.
