tion of the unit.
yRead all instructions be-
fore using equipment.
yFor your safety, the equipment is
furnished with a properly grounded
cord connector. Do not attempt to
defeat the grounded connector.
yInstall or locate the equipment only
for its intended use as described in
this manual. Do not use corrosive
chemicals in this equipment.
yDo not operate this equipment if
it has a damaged cord or plug, if
it is not working properly, or if it
has been damaged or dropped.
yThis equipment should be serviced
by qualied personnel only. Contact
your nearest Authorized Service
Agency for adjustment or repair.
yDo not block or cover any
openings on the unit.
yDo not immerse cord or plug in water.
yKeep cord away from heated surfaces.
yDo not allow cord to hang over
edge of table or counter.
yTurn the power o, unplug the
power cord, and allow unit to cool
down before performing any service
or maintenance on the unit.
yThe equipment should be grounded
according to local electrical codes
to prevent the possibility of electri-
cal shock. It requires a grounded
receptacle with separate electrical
lines, protected by fuses or circuit
breaker of the proper rating.
yAll electrical connections must be in
accordance with local electrical codes
and any other applicable codes.
yDo not clean this appli-
ance with a water jet.
yThis appliance is not to be used by
persons (including children) with
reduced physical, sensory, or mental
capabilities, or lack of experience and
knowledge unless they have been
given supervision or instructions.
yDo not allow children to
play with the appliance.
WARNINGS
Be advised of the following warnings when
operating and performing maintenance on
this unit.
yIf the supply cord is damaged, it must
be replaced by the manufacturer or
its service agent or a similarly quali-
ed person in order to avoid a hazard.
yDo not modify the power sup-
ply cord plug. if it does not t the
outlet, have a proper outlet in-
stalled by a qualied electrician.
yDo not use an extension
cord with this appliance.
yElectrical ground is re-
quired on this appliance.
yCheck with a qualied electri-
cian if you are unsure if the ap-
pliance is properly grounded.
yIf a chemical cleaner is used, be
sure it is safe to use on cast alu-
minum. Observe all precautions
and warnings on product label.
yInspection, testing, and repair
of electrical equipment should
only be performed by quali-

yThis equipment is to be installed to
comply with the basic plumbing code
of the Building Ocials and Code
Administrators, Inc. (BOCA) and the
Food Service Sanitation Manual of the
Food and Drug Administration (FDA).
yTo ensure proper steaming character-
istics, some calcium/mineral deposits
must be present on the genera-
tor surface. If, during cleaning, the
surface does become free of calcium/
mineral deposits, add plain tap water
to the surface and allow it to boil o.
This may have to be repeated several
times to ensure proper steaming
characteristics by creating a thin
layer of deposits on the surface.
yDo not use a sanitizing solu-
tion or abrasive materials. The
use of these may cause damage
to the stainless steel nish.
yChlorides or phosphates in clean-
ing agents (e.g. bleach, sanitizers,
degreasers or detergents) could cause
permanent damage to stainless steel
equipment. The damage is usually in
the form of discoloration, dulling of
metal surface nish, pits, voids, holes,
or cracks. This damage is permanent
and not covered by warranty.
yThe following tips are recom-
mended for maintenance of your
stainless steel equipment:
yAlways use soft, damp cloth for
cleaning, rinse with clear water and
wipe dry. When required, always rub
in direction of metal polish lines.
yRoutine cleaning should be
done daily with soap, ammo-
nia detergent, and water.
yStains and spots should be sponged
using a vinegar solution.
yFinger marks and smears should be
rubbed o using soap and water.
yHard water spots should be re-
moved using a vinegar solution.
