INTRODUCTION

This service and parts manual contains general infor­mation, installation operation, principles of operation,
trouble-shooting, and maintenance information for
the Market Forge 3500 Pressureless Steam Cookers.
Also included is a parts list in which each replaceable
part is identied and shown in an accompanying ex­ploded view.

The 3500 is a pressureless steam cooker consist­ing of two independently controlled compartments
enclosed in a single cabinet. Each compartment is
equipped with a separate three-piece door with inner
gasket plate isolated from the exterior surface.

Door latches operate by action for positive sealing
of inner door. Steam and steam-condensing circuits
are electrically controlled. Operating controls are dis­played on a single front-mounted panel and include
separate timers with indicator lights for selection of
constant steam or 60 minute long duration cooking.

A separate steam source required for operation of the
Pressureless Cooker is normally purchased with it,
please refer to the respective manual for guidance.

BASIC FUNCTIONING:

The Model 3500 may be operated with only one
compartment in use; or both may be used simultane­ously. Each compartment is equipped with identical
controls, allowing selection of constant steam or 60
minute timer operation.

The cooker becomes operational when it is set to con­stant steam, or the timer is set at the desired cooking
time and the compartment door is closed. The indi­cator light comes on and the steam solenoid valve

opens, allowing steam to ow into the compartment.

At the end of the set interval, timer contacts switch
to shut off the cooking operation and sound a signal
buzzer. The buzzer is silenced by returning the timer
dial to the OFF position. In the constant steam mode,
operation will be continuous.

Steam emitted from the compartment along with liquid
cooking drainage is directed through a drain screen
inside the compartment into the cooker drain line.

A cold water solenoid valve connected into the cooker
drain line is automatically actuated by a thermostatic
switch in the boiler drain to condense the steam to
water prior to discharge into the boiler drain.

SERVICE:

Required service, both preventive and corrective, is
explained in Section 6. Should repairs be required, a
network of authorized agencies is available to assist
with prompt service.

The model and serial numbers must be referenced
when corresponding with Market Forge.

When steam owing inside the compartment has

raised the interior temperature to 195°F, the contacts
of a thermostatic switch automatically close, complet­ing the circuit to the timer motor and starting the cook­ing time period.

The data plate containing the serial number pertain­ing to the equipment is located on the lower front trim
of the cabinet.

INSTALLATION

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:

Remove the four bolts that fasten the equipment

1.
frame to the skid.

Install feet in threaded mounting locations of the

2.
cabinet frame.

Mount the two bafes on studs located on the right-

3.
inside of the cooking compartments.

Mount the four pan support racks in brackets inside

4.
control compartments.

Attach panels to lower cabinet. Detailed instruc-

5.
tions are enclosed with the panels.

Attach the drip trough on studs located on the face

6.
of the unit.

Equipment failure caused by inadequate water qual­ity is not covered under warranty.

CAUTION:

PVC or CPVC are not acceptable materials for drains.

INSTALLATION CHECK-OUT:

Check-out procedures for the cooker mounted on
steam boilers of electric, gas, and steam coil utility or
direct-connected steam are given in separate installa­tion instructions for each. If the cooker fails to perform
as described, consult the Trouble-Shooting Guide for
corrective action. If difculty 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 on
page 3 and with the function of each control described
in Table 1 on page 5. Reference Figure 1, also on
page 5 for identication of controls required in the fol­lowing procedures.

SETTING IN PLACE:

The location of installation must be under an exhaust
hood, which will remove small amounts of water va­por emitted when the cooker doors are opened, and
exhaust fumes from the air. Level the unit in nal loca­tion by turning the adjustable feet. Using the cabinet
top as a reference, obtain level adjustment left-to­right and front-to-back.

MECHANICAL CONNECTIONS:

Since the Pressureless Cooker is interconnected at
the factory to the steam boiler or direct steam plumb-

ing, no eld 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 oor 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.

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.

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.

All steam boiler controls are in the operating mode

1.
and 15 PSI steam is applied to the cooker inlet
plumbing.

Cooker timers for both compartments (Figure 1,

2.
page 5) are in the OFF position.

Cooker compartments are empty of all information

3.
materials, pan supports are mounted in place, and
doors are open.

COOKER CHECK-OUT:

The cooker check-out procedures are as follows:

With the doors open set timers to about the “4 min-

1.

ute” position. Observe that indicator lights are off
and steam does not enter compartments.

Close cooker compartment doors. Observe that

2.

indicator lights turn on, and steam can be heard
rushing into the compartment simultaneously with
the door closing.

Observe the boiler drain line for passage of steam

3.

into the open oor drain. Correct steam condenser
operation is evidenced by presence of water ow-

2

INSTALLATION

ing from the drain line.

Observe cooker operation for several minutes. Op-

4.
eration 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.

SHUT-DOWN PROCEDURE:

No shut-down procedure is required for the Pressure­less Cooker except to check that all timer dials (2) are
in the OFF position and the compartment doors are
open. Consult the steam boiler instruction plate and
complete the shut-down procedures for the boiler.

3.
in compartment and leave door open.

DRAINAGE:
 COOKING COMPARTMENT DRAINAGE:

The bottom of the cooking compartment is angled
slightly toward the rear of the unit. This assures that
any condensate build-up or spills will be directed to­ward the drain hole, which is located at the rear bot­tom center of the cooking compartment. Any liquid
exiting the cooking compartment runs down the cook­ing compartment drain tube and into the drain line.

Turn off buzzer, which sounds to indicate cooking is

5.
complete, by setting timer dial (1) to the OFF posi­tion.

Open door sightly at rst letting most of the steam

TEST KITCHEN BULLETIN

MODEL 3500 PRESSURELESS COOKER FACTS ON PARADE

Frozen vegetables should always be cooked in perforated 12” x 20” x 2 1/2” pans 7 1/2 lbs (34 kg) maxi-

1.

mum per pan.

Frozen entrees should be underlined with a perforated pan for best results. If they are defrosted rst, the

2.

heating time will be decreased.

Fresh foods may also be cooked in this unit. Vegetables and other foods where the stock is not to be

3.

retained should be cooked in perforated 12” x 20” x 2 1/2” pans for the most nutritious results.

There is a thermostatic time delay built into this unit which adapts the unit to the proper cooking time. This

4.

means that the total time will usually be longer than the time setting.

There is a safety microswitch on the door which shuts off the steam each time the door is opened if the

5.

unit is in the cooking cycle.

Both compartments may be lled and timers set simultaneously.

6.

Total cooking time will vary depending on the load, even though the timer setting is the same.

7.

All foods, except cakes and pastry, can be cooked in a steam cooking unit.

8.

Steam cooked meals have greater nutritional value since they retain most of their vitamins and minerals.

9.

Because foods are cooked faster by the higher temperatures of steam cooking, they can be prepared

10.

closer to serving time, insuring maximum freshness.

Steam cooked foods have a higher percent yield more portions per dollar spent.

11.

Food may be served from the same pan in which it is steam cooked, thus reducing food breakage since

12.

there is no extra handling or transferring of food from cooking pans to serving pans. It also reduces pot
washing tasks.

Some important advantages of steam cooking are labor saving, reduced operating costs, space saving,

13.

and the lifting of heavy stock pots is eliminated.

Rice and spaghetti products, if thoroughly wet at the start of the cooking process, are very easily pre-

14.

pared.

Food such as potatoes, poultry, seafood, and some meats may be blanched in the steam cooker, thus

15.

reducing the total cooking time and grease absorption.

Fuel is used only when the steam cooking unit is in operation.

16.

The steam cooker will loosen foods burned on pans making washing easier.

17.

Solid pans are recommended when liquid is to be retained and perforated pans when the liquid is not to

18.

be retained.

Eggs may be cooked out of the shell if they are to be chopped which eliminates peeling after steaming.

19.

The steam cooker can be opened during the cooking period to add or remove items. If any time is lost,

20.

and adjustment may be make on the timer.

Steam cooking information, including recommended pan size and type, weight per pan, cooking times and

21.

pan yields are given on the following pages of this bulletin.

OPERATION

PRESSURELESS STEAM COOKING TIMER SETTINGS

The 3500 Pressureless Cooker is a two compartment unit. Each compartment holds ve 12” x 20” x 2 1/2” or three 12”

x 20” x 4” pans. This unit enables the cook to prepare foods close to the time of service. The cooking times given are
timer settings and should be set on a preheated compartment. There is a thermostatic time delay in each compartment
that adjusts the total time depending on the temperature and amount of the food. Therefore the total time will be greater

than the timer setting. At the end of the timer cooking cycle the bell will ring, steam will stop owing and the food can be

removed.

PRINCIPLES OF OPERATION

GENERAL:

The 3500 Pressureless Steam Cooker consists of two
identical cooking compartments, one above the other,
in a single cabinet assembly. Each compartment is

tted with independent electrically controlled steam

circuits and spring-loaded, self-sealing doors with
slam action latches. Compartments can be used sep­arately or simultaneously for either constant steam or
60 minute timing. The principles of operation in this
section include an explanation of steam, steam con­densing, and electrical circuits and their functioning.

PLUMBING CIRCUITS:

The plumbing circuits consist of the piping, steam so­lenoid valves, orice, drain, and cold water condens­er required to provide controlled steam application to

the cooking compartments. A simplied diagram of

these circuits is shown in Fig. 2 on page 5.

NOTE: Fig. 2 is strictly a pictorial schematic diagram

and is not intended to show the actual conguration

of the plumbing. All components are shown in correct
relationship with each other. However, the diagram
does not show their actual locations or position within
the cooker.

As shown in the diagram, steam inlet and exhaust
connections are connected at the factory directly into
a steam boiler or direct-connected steam plumbing
enclosed within the base cabinet on which the cooker
is mounted. The boiler (or direct-connected steam
control system) is equipped to supply constant, reg­ulated steam at 14–15 PSI. Steam exhaust, having
been reduced to water by the cold water condenser,

9

PRINCIPLES OF OPERATION

is directed into the boiler (or direct-connected steam
control) drain system. Steam inlet lines for compart­ments are equipped with normally closed solenoid
valves operated by the electrical control circuits. The
inlet valves are opened whenever the compartment
control circuit is activated by use of the 60 minute tim­ers.

STEAM INLET LINE:

A steam supply line is plumbed from the boiler output
(or direct-connected steam control) to a 1/2 inch barb

tting connected to the input sides of both steam inlet

solenoid valves. When a cooking compartment is not
in use, the valve for the compartment remains closed
to prevent steam from entering. During operation, the
appropriate inlet solenoid valve is opened by activa­tion of the control circuit.

Steam is projected onto the surface of pans of food

loaded into the compartment by an orice located
inside the compartment. Steam continues to ow

through the compartment in this manner until the con­trol circuit closes the solenoid valve.

STEAM EXHAUST AND DRAIN LINES:

Perforated strainers at the drain line openings inside
each compartment allow only steam, condensation,
and liquid cooking drainage to enter. Prior to dis­charge into the boiler drain system, steam is convert­ed to water by the cold water condensing systems for
each compartment.

STEAM EXHAUST CONDENSING SYSTEM:

The steam condensing system consists of the identi­cal, two-position, normally closed cold water solenoid
valves, with outlet sides connected into the exhaust
plumbing for each cooking compartment. A spray
nozzle directs cold water about the inside of the drain
lines to increase cold water contact with exhausted
steam.

Valve inlet sides are connected remote from the sup­ply line of the steam boiler (or direct-connected steam
plumbing). The valves respond to a thermostatic

switch located inside the compartment. When the
timer starts the cold water solenoids will energize.

ELECTRICAL CIRCUITS:

The electrical circuits of the cooker control the power
to activate timer motors and energize solenoid-oper­ated valves and circuits, which in turn control applica­tion of steam to the cooking compartment and con­densation of steam from the exhaust line. The cooker
operates on 120V, 2 amp, 60Hz electrical service
connected to all circuits from the circuits of the steam
boiler (or direct-connected steam controls) contained
within the cabinet on which the cooker is mounted.
Power is supplied to the control circuit at all times
when the shut-off device for the unit (supplied by the
user) is in the ON position.

CONTROL CIRCUIT COMPONENTS: A brief de­scription of the electrical circuit elements follows.

60 MINUTE TIMER/CONSTANT STEAM:

The timer contains a 120-volt AC synchronous mo­tor that drives a timing dial through a gear reduction
and clutch mechanism. The timer dial is manually set
for any interval of operation from 0 to 60 minutes or
constant steam as read on the calibrated dial face.
The manual rotation of the dial moves the common
element (1) of the timer switch from the neutral (OFF)
position to contact (3), which connects with the steam
inlet solenoid valve operating circuit.

The cooker is placed into automatic operation with
the setting of the timer dial. Its timing cycle, however,
is automatically delayed by a thermostatic switch,
which assures operating temperature is achieved be­fore the timer motor begins to “time out.” When the
timer motor has operated for the preset duration, the
common element is transferred to contact (4), return­ing the inlet solenoid valve to the closed position and
energizing the buzzer. Contact to the buzzer circuit
remains closed until the dial is manually turned to the
OFF position, returning the common element (1) of
the timer switch to the neutral position.

10

PRINCIPLES OF OPERATION

Fig. 2 Pictorial Diagram, Steam and Water Circuits

INDICATOR LIGHTS:

An indicator light is included for both compartments.
The light remains on (red) at all times when the co­inciding timer dial is set and the door interlock switch
is closed. The light turns off at the end of the timed
cooking duration.

BUZZER:

The buzzer is an alarm device that operates by oscil­lation of a striker against the core of an electromag­net. When the 60 minute timer dials reach the “0 Min­ute” position, the buzzer coil is energized to sound
the buzzer. Movement of the timer dial to the OFF
position opens the contact to the buzzer coil to shut
it off.

DOOR INTERLOCK SWITCH:

The interlock switch is a single-pole proximity switch
with normally open contacts. The switch is operated

by the proximity of a magnet within the door. When
the door is open, the switch contacts remain in the
open position. When the door is closed and secure­ly latched in place, the magnet is near the switch to
close the contacts. Connected between the operating
contact (3) of the timers and the steam inlet solenoid
valve, the door switch acts as a protective device to
interrupt valve operation unless the door is closed.

THERMOSTATIC SWITCH:

The thermostatically operated switch is a two-posi­tion, normally open switch mounted on the cooking
compartment. The switch functions to activate the
cold water solenoid valves of the steam condensing
system and to delay timer motor operation until the
compartment temperature reaches 195°F, thus as­suring that cooking temperature exists throughout the
timed duration.

11

TROUBLE-SHOOTING

GENERAL:

The information in this section is intended to assist
both the operator and service personnel in locating
the general source of problems that may occur with
the cooker. Before following any of the procedures
given in this section, the operator should be thor­oughly familiar with the operating instructions and
the function of all controls that are described in the
operating section of this manual. If the problem can­not be readily corrected, the operator should contact
the nearest Market Forge service agency for assis­tance.

TROUBLE-SHOOTING GUIDES:

Refer to the trouble-shooting guide for use by ser­vice personnel given on page 12-13.

page 15)

C. Faulty cold water solenoid. Replace valve.

D. Faulty wiring. Inspect condition of wire and tightness of all connections. Correct as needed.

ELECTRICAL FAULT ISOLATION:

Correction of an electrical failure rst requires isola­tion of the fault to a single circuit or component. In
most cases, the nature of the failure and its effect

upon the operation of the cooker will be sufcient to

narrow it down to one or more circuit elements. Re­fer to the isolating electrical faults table on page 14.

ELECTRICAL TROUBLE-SHOOTING PROCEDURES:

Before performing the trouble-shooting procedures
in this section, the serviceman must be familiar with
the function of all controls as described in the oper­ating section as well as with the principles of opera­tion section in this manual.

12

TROUBLE-SHOOTING

The electrical trouble-shooting procedures that follow
require access to components and terminals of the
electrical control panel shown in Fig. 6 on page 21.
Electrical controls are reached by removing screws
that fasten the control panel to the frame. The panel
may be pulled forward for testing while interconnect­ed to the cooker circuits or disconnected at the pin
connection for complete removal and repair.

INCOMING POWER:

Before trouble-shooting any of the electrical parts or
assemblies, verify that power is being supplied to the
cooker. Incoming power is connected at the boiler (or
direct-connected steam) control box located in the
base cabinet. With power connected to the cooker, an
AC volt-meter is used to measure 120 volts across L1
and L2. If 120 volts is present, and the cooker will not
operate, the fault lies within the electrical circuits of
the cooker.

ELECTRIC INSPECTION:

The rst step in any electrical trouble-shooting pro­cedure is a thorough physical inspection of all wiring
connections.

WARNING:

Before removing control panel or checking connec­tions and wiring, be sure that the circuit breaker for in­coming power is OFF. When power is supplied, all ex­posed terminals of the control panel carry 120 volts.

Check all wiring connections by hand to assure that
both ends of all connection points are tightly secured.
Use a screwdriver to tighten connection points. If nec­essary, visually inspect all quick-disconnect terminals
for evidence of corrosion. Terminals in this condition
should be separated, cleaned with emery cloth until
shiny, and tightly reconnected.

60 MINUTE TIMER:
 TIMER CONTACTS:

Defective timer contacts will result in failure of either
cooker compartment to operate. When this occurs,
remove the control panel and proceed as follows:

Turn off power to the cooker at external circuit

1.
breaker.

Disconnect all ve wires from timer terminals. (see

TROUBLE-SHOOTING

3.

Connect an ohmmeter between terminals 1 and 3.

Rotate timer dial beyond the “0 Minute” point (any

4.
setting) to obtain a reading of zero ohms on the
ohmmeter. If zero ohm reading cannot be obtained,
timer contacts are defective and the timer must be
replaced.

5.

Move ohmmeter leads to terminals 1 and 4.

Rotate timer dial to “0 Minute” position (an audible

6.
click indicates correct position). If zero ohm reading
cannot be obtained, the timer is defective and must
be replaced.

Remove ohmmeter and replace all ve leads on

7.
timer terminals as shown in Fig. 2 on page 11.

TIMER MOTOR:

A defective timer motor will cause continuous opera­tion in the Time mode, with the timer dial failing to
return to the “0 Minute” position. Since thermostatic
switch failure can cause the same symptom, fault
must rst be isolated to the timer by testing the ther­mostat (Refer to cooking compartment thermostatic
switch section on page 15).

Carefully check motor wire leads and tighten loose

1.

connections.

WARNING:

Use care while working with control panel. Termi­nals carry 120 volts.

Turn on power to the cooker.

2.

Connect an ohmmeter between the terminals of the

3.
switch.

Actuate the switch by closing the cooking compart-

4.
ment door. If a zero reading cannot be obtained,
the switch is defective and must be replaced.

5. Remove the ohmmeter and replace the leads on

switch terminals (see Fig. 2, page 11).

STEAM SOLENOID VALVES:

When either inlet solenoid valve fails to operate, the
fault may be a defective coil. A defective coil is found
using an AC volt-meter to check the voltage at the coil
wire terminals, with the cooker compartment operat­ing in either constant steam or 60 minute timer mode.
If voltage of 120 volts is present and the coil fails to
open the valves, the fault is in the valve coil. Defec­tive valve coils are not separately replaceable, requir­ing complete valve replacement.

INDICATOR LIGHTS:

If the cooker compartment functions correctly, with
the single exception that the indicator light fails to
light during operation, the fault is a defective indica-

tor light. A “burned out” or defective light is veried by

using an AC volt-meter at the leads, with input power
on the selector switch in the correct position for that
timer, the timer set, and the door latches closed. If
120 volts is present, the fault is in the indicator light
and requires replacement. If 120 volts is not present,
the fault is in the wiring or control components (selec­tor switch, timer, or door switch).

Set timer dial (any setting beyond “0 Minute”). If

3.
operation is correct, the motor will turn the dial to­ward “0 Minute.” If the motor fails to operate, it is
defective and the entire timer must be replaced.

Shut off power to the cooker.

4.

DOOR INTERLOCK SWITCH:

Malfunction of the cooker door interlock switch pre­vents timer indicator lights from turning on and steam
solenoid from opening when the timer dial is set. If
steam does not enter the compartment and the indi­cator light fails to turn on with the door latch securely
engaged, the fault may be in the door interlock switch.
Proceed as follows:

Turn off power to the cooker.

1.

Disconnect wires to the door switch terminals (see

2.

Fig. 2, page 11).

COOKING COMPARTMENT THERMOSTATIC SWITCH:

A thermostatic switch included in the circuit for the

timer motor delays timer operation until steam owing
into the compartment satises the temperature-actu-

ated switch device. If a timer motor fails to operate
within about one minute after the indicator light comes
on (with cooker compartment empty), the cause may
be a defective thermostatic switch. To test the switch,
proceed as follows:

Disconnect the two wires connected to the thermo-

1.
static switch terminals.

Connect an ohmmeter between the two terminals

2.
of the switch.

Place the cooker into operation and observe ohm-

3.
meter dial. Within one minute of operation, the
switch contacts close automatically to register a
zero ohm reading on the dial. If a zero ohm reading

15

TROUBLE-SHOOTING

is not obtained, the switch is defective.

Shut off cooker, disconnect ohmmeter leads, and

4.
replace wires on switch terminals.

BUZZER:

If the buzzer does not sound at the termination of the
operator-selected timer setting (timer dial returned
to “0 Minute” position), the fault may be a defective

buzzer. Buzzer operation is veried using an AC volt-

meter at buzzer coil connections with input power on
and selector switch and coinciding timer dial set at the
“0 Minute” position. If voltage is 120 volts, the fault is
in the buzzer, which must be replaced. If 120 volts is
not present, the fault is in the wiring or control compo­nents (timer or selector switch).

COLD WATER CONDENSER CIRCUIT:

If during cooker operation steam exits from the drain
line opening (located in lower boiler compartment) and
the condensing system fails to operate, as evidenced
by repeated discharge of water from the drain line,
the condensing circuit is malfunctioning. The failure
can be caused by a defective condenser thermostat
or cold water solenoid coil, or by wiring failure. To test
condenser thermostat, refer to cooking compartment
thermostatic switch section on page 15.

If the condenser thermostat functions correctly, but ei­ther of the cold water solenoid valves fails to operate,
the cause might be a faulty valve coil. A defective coil
is found using an AC volt-meter to check the voltage

at the coil wire terminals with the cooker compartment
in operation. If voltage of 120 volts is present and the
valve fails to open, the fault is in the valve coil. Defec­tive valve coils are separately replaceable.

WIRING:

All of the electrical components of the cooker (timers,
indicator lights, etc.) are connected to each other by
wiring shown in Fig. 2 on page 11.

If all of the electrical components are operating cor­rectly (and the incoming power has been checked),
but the cooker fails to operate, the fault lies in the
wiring.

Fig. 2 on page 11 is a diagram that shows all ter­minals and interconnections within the electrical cir-

cuits. All numbered terminals are identied and all

leads number-coded as shown. Connections can be
easily removed.

Figure 3 on page 14 also shows the schematically
information and is an aid in isolating circuits for test­ing.

Using an ohmmeter, wiring continuity between the
connections shown on the wiring diagram (Fig.

2, page 11) is readily veried. This is best done in

stages, removing only those wires required for each
continuity check. As each lead is replaced, it should
be checked for evidence of corrosion, and cleaned if
necessary. All leads must be tightly attached so as to
provide a good electrical connection.

MAINTENANCE

GENERAL:

This section contains both preventive and corrective
maintenance information. Preventive maintenance
may be performed by maintenance personnel at the
establishment in which the cooker is installed. It is
recommended that user personnel never attempt to
make repairs or replacements to the equipment with­out the assistance of authorized service. Assistance
in service methods or a current Directory of Autho­rized Agencies may be obtained from Market Forge
(Refer to service section on page 1).

PREVENTIVE MAINTENANCE:

A good preventive maintenance program begins with

the daily cleaning procedure described in the cleaning
section on page 4. Additional preventive maintenance
operations are presented in this section. In establish­ments that employ full-time maintenance personnel,
the tasks described can be assigned to them. For oth­er installations, tasks requiring mechanical or electri­cal experience should be performed by an authorized
service agency.

The following paragraphs set forth minimum preven­tive maintenance procedures that must be completed
periodically to assure continued trouble-free opera­tion of the cooker.

16
