INSTALLATION AND SERVICE CONNECTIONS
INSTALLATION INSTRUCTIONS +
Set Cooker in place and level appliance using spirit level. Mark
hole locations on floor through anchoring holes provided in flanged
adjustable feet.
Remove appliance and drill holes into location marker on floor and
insert proper anchoring devices,
Set Cooker back in proper position.
Re-level the appliance, levelling the unit left to right and front
to back. Appliance should be elevated on the right 1/16" to 1/8"
to assure proper compartment drainage.
Bolt and anchor appliance securely to the floor.
Seal bolts and flanged feet with Silastic or equivalent compound.
INFORMATION TO STEAM FITTER
Each cooking compartment requires approximately 2.5 BHP (86.25 Ibs.
of steam per hour) to operate satisfactorily.
Assuming availability of 30 p.s.il. supply steam pressure
immediately to the appliance, then pipe sizes of 1/2" or 3/4" ar 1"
will deliver respectively 90, 165, or 385 lbs. of steam per hour to
the appliance Heat Exchanger. From the foregoing to use 1/2" pipe
line would most likely prove inadequate.
An extremely important consideration is the pressure drop that will
occur through the steam supply line from its point of origin to the
appliance. The greater the length of piping and number of valves
and elbows, the greater will the pressure losses.
Consider a pressure drop of 1 (one) p.s.i. for each straight length
of pipe equivalent to 120 diameters of that pipe. Thus, a 1" pipe
having a straight length of 120”"(10 ft.) is equivalent to 120
diameters of that pipe and will a pressure loss of 1 p.s.1. through
that pipe.

Note, in 3/4" pipe size, that a Standard 90 Elbow, an Angle Valve
and a Globe Valve are equivalent to 1.8 feet, 10 feet and 18 feet
respectively of straight pipe.
Similarity, in 1" pipe size, a standard 90 Elbow, and Angle Valve
end a Globe Valve are equivalent to 2.2 feet, 12 feet and 23 feet
‘respectively of straight pipe.

Total of above = 20 + 2.2 +4 3 + 2.2 + 17 + 23 + 10 + 2.2 + 79.6
feet. Since each 10 foot is equivalent to 1 p.s.i. pressure
loss, _79.6 feet is equivalent to approximately 32 p.s.i. from an
original Boiler supply of 40 p.s.i.
It is suggested that, wherever possible, the steam supply line to
the appliance be a separate line from the steam source. ТЕ the
appliance must be supplied from a line supplying other
appliances, the pipe sizes and pressure will have to he verified.
Further, during idle periods, when the steam in the supply line
is not in use, water will form from condensed steam in the supply
. line and it is advisable to prevent water pockets from forming in
the steam line “and impeding the steam flow when it is required.
Therefore, contrive to have the steam supply line . level or run
slightly downwards towards the appliance. Install: a Ball Float
Trap near the appliance to drain out water (condensed steam) from
the line to assure clean dry steam to the appliance.

OPERATION INSTRUCTIONS
COOKER SECTION
#
With Ready light ON, Cooker is ready for use.
1.
2.
Place pans of food to be cooked into compartment and shut
door.
Set timer to cooking time desired.
Compartment will pre-heat to 185 F before the timer will
start, Then pre-heat thermostat allows for varying product
and size of portions to be cooked.
Cooking cycle may be interrupted at anytime by opening the
compartment door and resumed again by closing door.
When buzzer sounds, it indicates the end of the cooking
cycle and that no more steam is entering the compartment.
Cooking light will go off and READY light will come ON.
Buzzer must be shut off by turning the timer to its OFF
position. |
WARNING: THE COOKING COMPARTMENT CONTAIN LIVE STEAM AND TO AVOID
SCALDING AND/OR BURNS STAY CLEAR WHEN OPENING EACH
DOOR.
SHUT DOWN
a) To shut down cooking compartment, set timers to their OFF
position and leave doors slightly open.
bp) At the end of the day, the steam supply must be shut off.
NEVER SPRAY WATER INTO ELÉCTRIC CONTROLS
CONTACT THE FACTORY, THE FACTORY REPRESENTATIVE OR A LOCAL
SERVICE COMPANY TO PERFORM MAINTENANCE AND REPAIRS SHOULD THE
APPLIANCE MALFUNCTION. REFER TO WARRANTY TERMS.
