SECTION 2 INSTALLATION
2.1 Assembly
The Pressureless Cooker is factory-mounted on a cabinet
base containing either a steam boiler or direct steam
connection controls for the cooker. The assembled unit is
shipped bolted to a skid, with cabinet feet in a separate
container. Steps required for assembly are as follows:
1. Remove the four bolts that fasten the equipment frame
to the skid.
2. Install feet in threaded mounting locations of the cabinet
frame.
3. Mount the two pan support racks in brackets and studs
inside cooking compartment.
4. Attach panels to lower cabinet. Detailed instructions are
enclosed with the panels.
5. Attach the drip trough on studs located on the face of
the unit.
2.2 Setting in Place
Level the unit in final location by turning the adjustable
feet. Using the cabinet top as a reference, obtain level
adjustment left-to-right and front-to-back.
2.3 Mechanical Connections
Since the Pressureless Cooker is interconnected at the
factory to the steam boiler or direct steam plumbing, no
field connections to the cooker are required. All electrical
and plumbing connections are routed to the steam boiler
cabinet through the 6-inch-high space between the floor
and the bottom edge of the cabinet frame. Connection
locations for the cooker mounted on steam boilers of
electric, gas, and steam coil utility and direct-connected
steam are shown in separate installation instructions for
each.
2.4 Water Connections
Before connecting water to this unit, have water supply
analyzed to make sure that hardness is no grater than
2.0 grains per gallon and pH level is within the range of
7.0–8.5. Water that fails to meet these standards should
be treated by the installation of a water conditioner.
2.5 Installation Check-Out
Check-out procedures for the cooker mounted on steam
boilers of electric, gas, and steam coil or direct-connected
steam are given in separate installation instructions for
each. Procedures for the cooker only are included in
Subsection 2.5.2.
If the cooker fails to perform as described, consult Table 5-
1 of the Trouble-Shooting Guide for corrective action. If
difficulty arises with the boiler, reference the separate
service and parts manual for that equipment.
Before making this check-out, the operator must be
thoroughly familiar with the operating procedures in
Section 3 and with the function of each control described
in Table 3-1. Reference Figure 3-1 for identification of
controls required in the following procedures.
2.5.1 Initial Control Settings
Before beginning the start-up procedures for the cooker,
the instruction plate and service manual for the steam
boiler must be consulted and all start-up procedures
completed to supply 15 PSI steam to the steam inlet line
for the cooker.
1. All steam boiler controls are in the operating mode and
15 PSI steam is applied to the cooker inlet plumbing.
2. Cooker timer for the compartment (Figure 3-1) is in the
OFF position.
3. Cooker compartment is empty of all information
materials, pan supports are mounted in place, and door
is open.
2.5.2 Cooker Check-Out
The cooker check-out procedures are as follows:
1. With the door open set timer to about the “4-minute”
position. Observe that indicator light is off and steam
does not enter compartment.
2. Close cooker compartment door. Observe that indicator
light turns on, and steam can be heard rushing into the
compartment simultaneously with the door closing.
3. Observe the boiler drain line for passage of steam into
the open floor drain. Correct steam condenser operation
is evidenced by presence of water flowing from the
drain line.
4. Observe cooker operation for several minutes. Opera-
tion is correct if timer dials begin to rotate after a short
delay period required for preheating. After the delay
period plus the “4-minute” initial setting, the timer dials
will return to the “0-Minute” position, at which a buzzer
sounds. The buzzer is silenced by turning the dial to the
OFF position.
