NOTES

1. Accutemp griddle mounting;

This version of the Installation Manual for the Market Forge oven model MSA-SB-2600 includes the (4) parts (listed

below) that were modied in order to accept the Accutemp Griddle being mounted on top. All ovens shipped from the
Market Forge factory with a Serial Number less than #226167 will require a back t kit, Market Forge part number 98­4162, in order to mount the Accutemp griddle. The back t kit includes the updated version of the (4) parts listed below
and installation instructions. A simple replacement of these (4) parts with the back t kit parts will allow the griddle to be
mounted on top. The tools required to perform the replacement are a slotted screwdriver and a 7/16” socket wrench.

2. Replacement Reed Switch

This version of the Installation Manual for the Market Forge oven model MSA-SB-2600 includes a new part number for
the Reed Switch (sometimes referred to as a Proximity Switch). Due to alignment issues with the original Reed Switch
a new, more forgiving Reed Switch is now being used. The new Reed Switch part number 08-6615 should be used as a
direct replacement for part number 08-6308 in older model MSA-SB-2600 ovens.

All ovens shipped from the Market Forge factory with a Serial Number less than #225207 will have the original Reed Switch
08-6308. These can be directly replaced with the new Reed Switch 08-6615.

Introduction

YOUR ENERGY EFFICIENT CONVECTION OVEN

MSA-SB-2600 convection ovens are electrically powered,

high capacity ovens featuring high energy efciency.

These ovens are designed to radically cut power con­sumption, delivering the cooking power of a 16 KW oven
from only 11 KW’s of energy input. Improvement of ener­gy use is made possible by a carefully designed insulating
system which keeps heat inside the oven longer.

A convector fan distributes heat uniformly throughout the
oven interior, for fast even roasting and baking.

Like all Market Forge products, MSA-SB-2600 ovens are
built to the highest standards of workmanship, employ-

ing only the nest materials and components. Of course,

Power Saver II ovens are fully approved by UL, and other

ofcial testing authorities.

HOW THE OVEN OPERATES

MSA-SB-2600 ovens operate by use of two simple con­trols, a power switch for turning on the fan motor and
control circuit, and a thermostat for setting the oven tem­perature. The oven is otherwise automatic. A thermostat
maintains oven temperature by cycling heating elements

on and off, with temperature uctuating no more than

20°F from the setting. Uniform distribution of heat within
the oven is assured by continuous operation of a convec­tor fan.

A 60-minute and Constant Heat timer serves as an aid in

using the oven, when the timer expires the heating ele­ments shut off. To prevent unnecessary loss of heat when
the doors are opened, an interlock switch stops fan oper­ation whenever the right-side door is opened. Should the
operator wish to cool the oven, opening just the left- side

door will quickly ventilate the oven interior.

Assembly Instructions

INTRODUCTION

The model MSA-SB-2600:

Submarine-Accessible Convection Oven contains 88 total
parts for assembly and is designed such that it can be as­sembled in a submarine’s galley with simple tools.

Sub-Assemblies

The total assembly is broken down into 7 sub-assemblies:

• Main Frame Assembly

• Oven Cavity Assembly

• Control Panel Assembly

• Motor/Transformer Assembly

• Inside Oven Cavity Assembly

• Door Assembly

• Outer Skin Assembly

Time Estimate

The estimated time for complete assembly is approx-

mately 6-7 hours for a rst timer or 4-5 hours for an

experienced assembler. The oven assembly can be
completed with one person, but for a more produc­tive assembly two people are recommended.

Tools required for assembly:

• Power drill (Cordless drills 12 V or higher)

• Screw driver set

• Screw starter

• Allen wrench set

• Socket Set

• Open wrench Set

• Mallet

Sealant

Use RTV 106 high temperature silicone rubber adhesive
sealant as needed to provide a tight seal to any area that

requires it. Also use Loctite 268 on all fasteners that will

be permanently fastened.

The controls required to operate the oven are listed in the

following table together with a short functional description
of each.

Item Description

1 Thermostat Control - Regulates oven temper-

ature. Controls heating element operation.

2 Thermostat Light - Indicates when the thermo-

stat is calling for heat and the elements are ON.

3 Timer/Constant Heat - Electrical timer to aid

in time cooking cycles. Controls oven and con­stant heat mode.

4 Power Light - Indicates power is ON.

5 Power/Fan Switch - Three position fan switch.

Controls fan speed either HIGH/LOW or in the

middle position the oven is OFF.

OPERATING INSTRUCTIONS

1. Check that power is available to the oven

2. Arrange shelf positions according to the item to be
cooked.

3. Close doors. Move fan switch to HIGH or LOW. Fan
should come on.

4. Set thermostat dial to desired cooking temperature.

Element indicator light should come on

5. Allow oven to preheat for about 5-10 minutes. Pre­heating is complete when indicator light goes out and

the buzzer sounds. Do not waste energy by turning

the oven on too early.

6. Load oven. The load should be adjacent to the oven,
so the doors will be open as short a time as possible.

3

5

4

7. Close doors. Set timer for desired cooking time.

8. Buzzer will sound at end of preset interval. Oven is
ready to unload.

9. If oven temperature is to be lowered, set the thermo­stat to the desired temperature to cool interior. Fan
will continue to run with left door open and right door
closed. Where indicator light comes on, oven is at
lower temperature. Close left door. When light goes
off, oven is ready for use.

10. For daily shutdown, place oven thermostat and pow­er switch in OFF position. For extended shut- down,
leave doors ajar as well.

OPERATION

Figure 50

18

A good preventive maintenance program in the form of
daily cleaning procedures is outlined in the following
steps:

1. Remove oven shelves and wash in mild detergent
and water. Rinse and dry.

2. Remove left and right hand shelf supports by lifting up
and out toward center of oven. Wash, rinse and dry.

3. Remove fan bafe by lifting up and out. Wash, rinse
and dry.

4. Wash interior sides, bottom, and top with mild deter­gent and water. A stainless steel cleaner (not polish)
should be used for the interior. Rinse and dry.

5. Replace fan bafe, shelf supports and shelves.

6. Wash both sides of doors, top & bottom trim using a
stainless steel cleaner. Rinse and dry.
