-

rious injury by providing training programs to acquaint all 

equipment operators with the correct and safe methods of 

operation.

Operators must be made aware of the consequences of 

misuse. Steam producing equipment, no matter who the 

manufacturer is inherently dangerous when misused. The 

possibility of serious scalding always exists, the careless 

and/or untrained operator will be injured.

This  equipment  must  be  maintained  accordingly  to  the 

guidelines  in  this  manual  (

see  section  6,  maintenance

). 

Lack of maintenance will lead to a potentially hazardous 

condition  and  possible  liability.  Operators  should  report 

any  equipment  malfunction  immediately  and  steps  must 

be taken to correct the problem before further use of the 

equipment is allowed.

Keep this manual for daily reference.

WARNING:

  IMPROPER  INSTALLATION,  ADJUSTMENTS, 

ALTERATION,  SERVICE  OR  MAINTENANCE  CAN  CAUSE

1.2 DESCRIPTION

The Steam-Tech Plus is a pressureless steam cooker consist

-

ing of two independently controlled cooking compartments in 

a single cabinet. Each compartment has its own independent 

control panel, consisting of a power switch, mode select switch, 

constant steam switch, timer (mechanical or electronic), steam 

demand indicator, and indicator lights for each of its functions. 

The Steam-Tech Plus is equipped with many unique features 

and functions. These features and functions will be discussed 

in greater detail in section 4 on page 4.1.

1.3 COOKING CAPACITIES

Each cooking compartment will accept:

Three 12” x 20” x 2.5” Pans.

The inside dimensions of the cooking compartments are: 

14.5”  Wide  x  10.75”  High  x  23”  Deep,  (

368mm

)  W  x 

(

273mm

) H x (

584mm

) D

1.4 BASIC FUNCTIONING

Each Steam-Tech Plus cooking compartment has its own in

-

dependent steam generator. Each os its two cooking compart

-

ments may be operated either independently or simultaneously. 

Each compartment is equipped with identical controls. These 

controls  allow  it  to  be  used  in  the  “TIMED  STEAM”  mode, 

“CONSTANT STEAM” untimed mode, or the “STEAM & HOLD” 

mode.

The Steam-Tech Plus utilizes a unique STEAM DEMANDS fea

-

ture. This feature allows the Steam-Tech Plus to operate at ex

-

tremely high cooking efficiencies. The Steam Demand System 

creates only the amount of steam as will be absorbed by the 

food being cooked, no more and no less. No excess steam is 

created, therefor, nothing is lost down the drain.

To begin operation, the POWER switch is pressed into the ON 

position, illuminating the power light. This opens the water feed 

solenoid valves,  to both the steam generator and tempering 

tank.  Once  the  appropriate  water  levels  have  been  reached 

the heating element is energized. When the water temperature

in the steam generator has reached 193

O

F the green READY 

light is illuminated indicating that the unit is now ready to make 

steam and all controls are functional.

Set the MODE SELECT switch to either STEAM or STEAM & 

HOLD. After  selecting  a  mode  the TIMER  knob  must  be  set 

to the desired cooking time for the generator to begin making 

steam.

In the STEAM mode the unit will create steam for the duration 

of the time you have set. Once the timer reaches the end of 

its cycle (

0 minutes

) the unit will stop making steam and the 

buzzer will sound. The buzzer is silenced bt returning the timer 

knob to the OFF position. The generator will idle at 193

O

F.

In the STEAM & HOLD mode the unit will create steam for the 

duration of the time you have set. Once the timer reaches the 

end of its cycle (

0 minutes

) the unit will stop making steam and 

go into HOLD mode illuminating the amber hold light. When in 

the HOLD mode the auxiliary thermostatically controlled elec

-

tric strip heater is activated. The strip heater is mounted onto 

the outside of the cooking compartment and will now act as a 

holding cabinet until you call for steam again. During this time 

the generator will idle at 193

O

F.

The CONSTANT STEAM button overrides the MODE SELECT 

switch  and  the  TIMER.  When  the  button  is  depressed,  the 

green constant steam light is illuminated. In this mode the gen

-

erator will create steam indefinitely as controlled by the steam 

demand system regardless of the MODE SELECT switch and 

TIMER setting, until the CONSTANT STEAM button is pressed 

again. While the constant steam button is depressed the timer 

may be used as an alarm only as it will have no effect on the 

creation of steam. To exit the constant steam mode the con

-

stant steam button must be pressed again. This will cause the 

green constant steam light to go off. The generator will now idle 

at 193

O

F ready to make steam.

All  drainage  is  routed  through  the  common  tempering  tank, 

which regulates the drain water temperature. This tank cools 

the drain water to 130

O

F before discharging it down the main 

drain line.

1.5 SERVICE

Required  service both preventive and corrective is explained 

in section 7 of this manual. Should repairs be required, a net

-
