IMPORTANT OWNER INFORMATION

INTRODUCTION

The Hatco STM-4G Electric Steamer is specially
designed for cooking, reheating, defrosting, and
bottling foods with steam. Inside the sealed cabinet
of the Electric Steamer, steam is allowed to
penetrate foods from all sides, heating foods evenly
and thoroughly. Steam prevents foods from drying
out so food remains moist and juices are not lost.
Cooking with steam brings out the distinct flavor of
the food retaining the food’s true taste. The Electric
Steamer is a healthier cooking alternative to
conventional methods.

Hatco Electric Steamer may also be used to
disinfect containers, kitchen utensils and other
items.

This manual provides the installation, safety and
operating instructions for the Electric Steamer unit.
We recommend all installation, operating and safety

instructions appearing in this manual be read prior to
installation or operation of your Electric Steamer unit.
Safety instructions that appear in this manual after a
warning symbol and the words WARNING or

CAUTION printed in bold face are very important.

WARNING means there is the possibility

of serious personal injury or death to yourself or
others. CAUTION means there is the possibility
of minor or moderate injury. NOTICE signifies the
possibility of equipment or property damage only.

Hatco Electric Steamer units are a product of
extensive research and field testing. The materials
used were selected for maximum durability,
attractive appearance and optimum performance.
Every unit is thoroughly inspected and tested prior
to shipment.

Record the model number, serial number
(identification decal located on the back of the unit),

IMPORTANT SAFETY INFORMATION

CAUTIONS

T o avoid injury or damage to the unit DO NOT
move or relocate the unit while it contains
any food product or water in the tank.

Some exterior surfaces on the unit will get
hot. Use caution when touching these areas
to avoid injury.

To avoid unsafe conditions do not mix
products that may contaminate each other
during thawing process.

For safe and proper operation do not place
food product directly onto bottom of unit.
Use of a perforated pan is recommended for
holding food product.

Do not place anything on top of the unit;
doing so could damage the unit or subject
personnel to possible injury.

Unit is not weatherproof. For safe and proper
operation the unit must be located indoors
where the ambient air temperature is a
minimum of 21°C (70°F) and a maximum of
29°C (85°F).

To avoid the risk of injury, use caution not to
spill hot food contents when removing
containers from unit.

T o avoid any injury or damage locate the unit
at the proper counter height, in an area that
is convenient for use. The location should be
level to prevent the unit or its contents from
accidentally falling, and strong enough to
support the weight of the unit and contents.

Do not fill with water above or beyond the
maximum water line (1 liter) on the water
tank or damage may occur to the unit.

NOTICES

To assure proper operation and to prevent lime
and scale buildup inside the unit, use distilled
water or water that has been treated to prevent
scale build-up.

Ensure the water tank is empty after each days
use to prevent sediment build up in the
appliance.

Do not use harsh chemicals such as bleach or
cleaners containing bleach. Also avoid the use
of scouring pads, hard brushes, or steel wool as
they may damage the surface of the appliance.

Cleaning and sanitizing is recommended at the
end of each days use.

Do not use cleaning products containing
aliphatic compounds as these could cause the
seals to swell.

Use only vinegar or citric acid based descaling
agents or descaling tablets to descale the
appliance.

Use only non-abrasive cleaners with non­abrasive sponges or cloths. Abrasive cleaners
could scratch the finish of your unit marring its
appearance and making it susceptible to soil
accumulation.

Do not use a steam cleaner to clean the outside
of this appliance. Pressurized steam could
cause permanent damage to the surface and
penetrate the electrical components causing the
appliance to short circuit.

Do not store cooked food in appliance for long
periods of time. The moisture in the food can
lead to corrosion in the appliance.

Use only suitable containers that are heat and
steam resistant to 100°C (212°F).

MODEL DESCRIPTION

STM-4G MODEL

Hatco's Electric Steamer produces steam in an
enclosed cabinet for cooking, reheating, defrosting,
or bottling of food products. When the oven door is
closed a seal is formed. The sealed oven cabinet
captures the steam and monitors the cabinet
temperature with an internal thermostat. To avoid
pressure buildup, steam is allowed to exit from the
front upper vents inside the cabinet. Inside the main
cabinet housing are side runners that support
cooking pans or racks, and are easily removed for
cleaning purposes. An independent cavity holds a
removable 1 liter (.3 gal.) water tank, essential for
the steam process. The steam oven has a outer drip
tray to collect condensation that may accumulate on
the door during operation.

The Electric Steamer comes equipped with a
condensation pan to collect excess moisture inside
the cabinet underneath the cooking pan(s), a
stainless steel perforated pan and a metal rack for
holding solid containers. Other pan options are
available.
