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.

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.

OPERATION

SUITABLE CONTAINERS

The Electric Steamer comes equipped with one ¼
size perforated stainless steel food pan. Optional
different size pans are available, both perforated
and solid.

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

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

When choosing the most suitable container for
particular food products, take into consideration the
following guidelines:

• Perforated pans are ideal for steaming large to
medium vegetables. The perforated pan allows
the steam to encompass the whole vegetable
and cook evenly and thoroughly.

• When using perforated pans, we recommend
placing a solid condensation pan underneath to
catch any dripping condensation.

NOTE: Two perforated pans containing different
foods should not be used at the same time in the
steam oven without being separated by a
condensation pan. The integrity of the food taste
may be jeopardized with moisture dripping from the
pan above.

• Solid shallow pans are recommended for dishes
that are more compact such as casseroles,
bakes, or foods small in size.

• Foods prepared in deeper pans will take longer
to cook.

• Use the metal rack when multiple smaller pans or
bottling is needed.

• All containers must be rated to withstand hot
steam up to 100°C (212°F) temperatures. Heat
resistant glass, ceramics, porcelain, plastic,
stainless steel or enamel dishes are all suitable
containers.

• Containers with thick sides will lengthen or
increase cook times.

• Ensure that at least a 30 mm (1") gap is left
between the upper rim of the container and the
top of the steam oven. This will allow for
sufficient steam to enter into the container.

Tips on Defrosting Foods

• The perforated pan is recommended for use in
the defrosting process, especially for all meats.
The condensation pan must be used underneath
the perforated pan to catch the thawing liquids
from the meats above. Defrosted liquids should
be discarded immediately and the container
washed before next use.

• All meat and poultry should be fully defrosted
before cooking.

• Fish does not need to be fully defrosted before
cooking. Defrost so that the surface of the fish is
sufficiently thawed to take seasoning.

• Remove any packaging from frozen foods before
defrosting.

• Do not refreeze food once it has been thawed.

• Halfway through the defrosting time it is
recommended to turn, stir, or separate clumps of
food.

• Allow food to stand at room temperature at the
end of the defrosting time. This standing time is
necessary to ensure that the food is fully
defrosted right through to the core.

• Defrost deep frozen pre-cooked meals according
to the manufacturer's instructions.

• Ensure clumps of frozen foods are broken up first
so that they cook evenly.

OPERATION

2. Place the dish with the longest cooking duration
in the oven first. Set the timer and temperature
according to that particular food. Refer to
OPERATION and the appropriate food chart.

3. Insert the dish with the second longest cooking
time when the timer display is close to the
cooking duration of that food. Repeat for the next
dish.

At the end of the longest cooking duration all foods
will be complete and ready to serve.

BLANCHING

The steam oven is a convenient way to blanch
vegetables and fruit to prepare them for freezing.

1. Place the prepared vegetables or fruit into a
perforated cooking container.

2. Set a duration of 1 minute and confirm the
selection.

3. After blanching duration is complete. Remove
and plunge the food product into cold water to
ensure rapid cooling.

4. Drain the food product thoroughly and prepare to
freeze.

DISINFECTING

Steam is an excellent source for disinfecting cooking
containers and utensils.

NOTE: Ensure the product to be disinfected is
declared by the manufacturer to be heat resistant up
to 100°C (212°F) before continuing.

1. Place the condensation tray on the lowest side
runner of the steam oven. Insert the metal rack
on the next level above the condensation tray.

2. Dismantle, clean and thoroughly rinse the items
to be disinfected. Place the items on the metal
rack ensuring that they do not touch each other.
This will allow the hot steam to encompass the
items from all sides.

3. Set the timer display to 30 minutes and confirm
the selection.

4. Remove items from the steam oven and dry with
a fresh clean towel. If assembly is required all
components must be completely dry before
reassembling, to keep them germ free.

minutes.

NOTE: The above data is only for reference.

Tips on Bottling or Canning Foods

• Place the condensation pan on the lowest level
inside the steam oven, and the metal rack on the
next level above the tray.

• Place a maximum of four prepared jars (all the
same size) on the rack, ensuring that they do not
touch one another. This allows steam to
surround the jars on all sides.

• Make use of residual heat by leaving the jars in
the steam oven 30 minutes after it has switched
off.

• Cover the jar or jars with a cloth and allow to cool
for approximately 24 hours.

MEAL PLANNING TIPS

It is very economical and practical to cook a whole
meal at the same time in the Electric Steamer.
Cooking durations will vary according to the type of
foods.

1. Ensure all food pans will fit inside the steam oven
together before proceeding with the steaming
process.

WARNING
Hot steam will escape from cabinet when door is
opened and injury may occur if user comes in
contact with steam or inside of steam oven
cabinet wall.

MAINTENANCE

GENERAL

The Hatco Electric Steamer ovens are designed for
maximum durability and performance, with minimum
maintenance.

CLEANING

Hatco recommends cleaning the Electric Steamer
after each days use. Allow the steam oven to cool
down to a safe temperature before cleaning.

NOTE: Do not close the door after cleaning until the
inside oven cavity is completely dry.

NOTE: Unplugging the appliance from the power
outlet will erase all menu programs and require
reprogramming of the unit.

WARNING
To ensure safe and proper operation additional
cleaning may be required depending upon
products being thawed and local codes applying
to sink thawing techniques.

WARNING
This appliance is not jet-proof construction. To
assure safe and proper operation do not use jet­clean-spray to clean this appliance.

NOTICE
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.

NOTICE
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.

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

NOTICE
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.

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

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

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

Oven Interior

Removing the side runners from the inside of the
oven cavity will make cleaning the oven interior
easier.

1. Pull the side runner toward the steam oven
opening, and remove the side runner from the
oven wall. (See Figure 6.)

2. With a mild solution of household dish soap and
water, use a non abrasive sponge or cloth to
wipe the interior clean. Use the same solution to
wipe the side runners, roof seal, drip channel,
inside of the door, and the independent water
cavity. (Side runners may be cleaned in a
dishwasher if available.)

NOTE: If steam oven interior is discolored from bad
water quality, use a proprietary wet cloth and a citric
acid based descaling agent to remove stains.

NOTE: The water drain floating disc and cover will
require use of a periodic cleaning agent to remove
water deposits.

3. Wipe the oven interior with clean water and
thoroughly dry. Ensure no cleaning product
residue is remaining on the steam oven.

NOTE: The door seal can become porous and
cracked over time. If this happens the door
assembly will need to be replaced.

4. Install the left and right side runners. Make sure
the rear tip of each runner engages the mounting
holes in the back of the cabinet, then slide the
mounting tabs over the locating pins and push
down to secure. (See Figure 6.)

MAINTENANCE

NOTE: Auto boiler drain occurs when the power is
switched off. The drain valve will be turned on for 1
minute to drain all the water/descaling agent in the
boiler to the drip pan and drain hose. There may be
some “noise” from the drain valve when the boiler
runs out of water and is empty.

Oven Exterior

1. With a mild solution of household dish soap and
water, use a non abrasive sponge or cloth to
wipe the exterior clean.

2. Wipe the oven exterior with clean water and
thoroughly dry.

WARNING
If service is required on this unit, contact your
Authorized Hatco Service Agent, or contact the
Hatco Service Department at 414-671-6350 or
International fax [phone].

WARNING
This product has no “user” serviceable parts. To
avoid damage to the unit or injury
to personnel, use only Authorized Hatco Service
Agents and Genuine Hatco Replacement Parts
when service is required.

WARNING
Genuine Hatco Replacement Parts are specified
to operate safely in the environments in which
they are used. Some aftermarket or generic
replacement parts do not have the
characteristics that will allow them to operate
safely in Hatco equipment. It is essential to use
Hatco Replacement Parts when repairing Hatco
equipment. Failure to use Hatco Replacement
Parts may subject operators of the equipment to
hazardous electrical voltage, resulting in
electrical shock or burn.

Water Container

1. Remove water tank from the water tank cavity.

2. Remove cover from water tank for cleaning
before using the Electric Steamer for the first
time.

3. Rinse the water tank and cover thoroughly by
hand using hot water.

4. Before placing water tank back into the cavity,
wipe outside of water tank until dry.

WARNING
To avoid electrical shock or personal injury, DO
NOT insert into the unit a water tank that is wet
on the outside.

Boiler Cleaning

NOTE: Hatco recommends connecting a hose to the
drip pan for drainage.

NOTE: The amount of mineral content in the water
and how often the unit is operated will dictate how
often the boiler requires cleaning. It is
recommended that home users perform this
procedure monthly and commercial users perform
this procedure weekly . Hard water usage will require
that the boiler be cleaned more frequently.

1. Leave power cord connected to the power supply
and turn the unit off and allow to cool. The boiler
will now begin draining.

2. Remove any pans or racks from the inside.

3. Fill the water tank with proper mixture of citric
acid based descaling agents, or descaling tablets
and water or vinegar to descale appliance.

4. Turn unit On. Start the steam cycle for one
minute at 50°C.

5. When steam starts coming out, immediately
press the Start/Stop button to stop the cycle and
open the door to cool the unit. Descaling agent
will now stay inside the boiler tank. Allow
descaling agent to soak for 15 minutes.

6. Turn the power Off and the boiler will now drain
the descaling agent.

7. Repeat this procedure with water only, until
discharge is clear.
