Equipment Description

OM-EE

Groen Model EE are floor-mounted, tilting,
steam-jacketed kettles which have
thermostatically controlled, self-contained,
electrically-heated steam supplies and
appropriate controls, mounted on a sturdy base.
Heat produced by electric heating elements
boils water in a reservoir below the jacket to
produce steam under pressure.

The kettle is surrounded by air-insulated
stainless steel sheathing. Stainless steel panels
enclose all of the controls. Three stainless
steel, tubular legs support the unit.
EE kettles
100 gallon capacities. Kettle bodies are welded
into one piece. Models are all equipped with a
sanitary tangent draw-off (product faucet) valve
and a stainless steel strainer. This standard
draw-off is two inches in diameter, and uses a
compression disc valve. The unit is controlled
with a thermostat, which turns electric power on
or off, and sets the cooking temperature.
Instruments are provided to show what is
happening inside the unit:

• Water gauge glass: shows the level of water

• Pressure/vacuum gauge: shows the steam

• Indicator lamp: Lights when the kettle is

being heated

Automatic controls within the unit:

• Contactor: Controlled by the thermostat,
turns heating element power on or off

• Low-water cutoff: Turns off power to keep
heating elements from overheating if water
loss exposes them above the water level.

• Safety valve: Releases steam if jacket
pressure gets too high

The jacket is filled at the factory with wate
contains rust inhibitors. When air is removed
from the jacket, the kettle efficiently provides a
uniform heating temperature range of 150
approximately 270
allows the kettle to be used for warming,
simmering, boiling or braising.

The interior of the kettle is polished to a 180
emery grit finish and the exterior is given a
uniform Number 4 finish. The unit is ASME
shop inspected and registered with the National
Board for working pressures up to 30 PSI.

Optional equipment for the EE
includes:

• Three inch draw-off valve

• 1/4” perforated or solid disc strainer

• Basket inserts (TRI-BC)

• Water fill faucets

• Automatic water filler

• Kettle brush kit

Inspection & Unpacking

The unit will arrive in a heavy shipping carton
and will be banded to a skid. Immediately upon
receipt, inspect the carton carefully for exterior
damage.

CAUTION
SHIPPING STRAPS ARE UNDER TENSION
AND CAN SNAP BACK WHEN CUT. TAKE
CARE TO AVOID PERSONAL INJURY OR
DAMAGE TO THE UNIT BY STAPLES
LEFT IN THE WALLS OF THE CARTON.

Carefully cut any polyester straps around the
carton and detach the sides of the box from the
skid. Pull the carton up off the unit.

Thoroughly inspect the unit for concealed
damage. Report any shipping damage or
incorrect shipments to the delivery agent.

Write down the model number, serial number,
and installation date, and retain this information
for future reference. Space for these entries is
provided at the top of the Service Log at the
back of this manual. Keep this manual on file
and available for operators to use.

CAUTION
THIS UNIT IS VERY HEAVY. INSTALLER
SHOULD OBTAIN HELP AS NEEDED TO
LIFT THIS WEIGHT SAFELY.

When installation is to begin, carefully cut any
straps which hold the unit on the skid. Lift the
unit straight up off the skid. Examine packing
materials to be sure that loose parts are not
discarded with the materials.

The unit will arrive in a heavy carton.

Inside it will be banded to a skid.
