Before permanently turning on gas to the steamer or after any service to the gas supply, test
all pipe joints for leaks with a soap and water solution. All leaks must be corrected before
attempting to operate the steamer.

WARNING

FIRE OR EXPLOSION HAZARD

2). Pressure Testing the Gas Supply Lines

The steamer must be isolated from the gas supply system during any pressure testing as
follows:

· The appliance and its main manual shut-off valve must be disconnected
supply piping system during any pressure testing of the system at test pressures in
excess of 14” water column (½ psi or 3.45 kPa). Be sure to leak test all fittings with a
soap and water solution after reconnecting the gas supply.

· The appliance must be isolated from the gas supply piping system by closing its main
manual shut-off valve during any pressure testing of the gas supply piping system at test
pressures equal to or less than 14” water column (½ psi or 3.45 kPa).

5. Install Electric Power Lines

The electrical supply must match the power requirements specified on the steamers rating plate and be
made in accordance with the following requirements.

a. The steamer must be grounded and have the electrical power lines installed in accordance with

local codes and/or the National Electric Code, ANSI/NFPA No. 70-LATEST EDITION (USA) or the
Canadian Electrical Code, CSA C22.2, as applicable. The wiring diagram is located on the back of
the lower front panel.

6. Water Supply Requirements and Installation
a. Water Supply Requirements

Using water not within the limits specified in this
manual could void or reduce Cleveland Range’s
warranty coverage of the steamer.

CAUTION

1). Water Quality

GROUND

LUG

As with any steam generating equipment, poor water quality degrades the performance of the
steamer.

Check the quality of supply water as described below before starting construction of the water
supply lines. If a water treatment system must be installed to achieve acceptable water quality,
install it before connecting the water supply lines to the Gemini Steamer.

If softened or chlorinated water is used in a Gemini steam generator, a carbon type filter must
be used for the water before it enters the steamer to remove Chlorine or other salts. If the water
supply is treated or softened either by the Water Company or on the premises, it may contain
chlorine or various salts. These additives are damaging to the steam generator. Salts and
chlorine used to soften or treat water cause rapid scale buildup, and/or increased corrosion if
allowed to flow into the steamer.

Contact a local water treatment specialist for an on-the-premises water analysis. The
recommended minimum feed water quality requirements for the steamer are listed in Table 2-1.

12

Table 2-1. Minimum Water Quality Requirements

Scale Forming Factors

Total Dissolved Solids less than 60 parts per million
Silica less than 13 parts per million
Alkalinity less than 20 parts per million

Corrosion-Causing Factors:
Free Chlorine less than 0.5 parts per million

Chloride less than 30 parts per million
PH factor greater than 7.5

2). Water Supply System

Provide a water supply system that fulfills the requirements of the limits listed in Table 2-1. The
supply must provide a minimum dynamic pressure of 35 psi (2.4 kg/cm
pressure of 60 psi (4.1 kg/cm

2

).

2

) and a maximum static

·

If analysis shows that the supply water is NOT within the required limits, either a water
treatment system and/or carbon filter must be installed in the line feeding the steam
generator or the frequency of maintenance, cleaning, and descaling must be increased
beyond that recommended in the maintenance schedule (Chapter 3). If more frequent
descaling is selected as the means of protecting the steamer from premature failure, the
“DESCALE REQUIRED” light timing should be readjusted to reflect the increased cleaning
schedule.

b. Setting the Descale Required Light

The Descale Required Light feature
tracks the number of hours the unit has
been operating since it was last reset,
and lights when it is time for descaling.

1). General

The Descale Required Light consists of
an indicator light, a solid state timer
module, and a reset/rocker switch. (The
light and reset switch consist of a single
device on the front panel identified by the
“DESCALE REQUIRED” label.) See
Figure 2-8. The timer is a digital clock
module inside the unit that keeps track of
how many hours your steamer has been
in operation since the last reset of the
timer.

DESCALE REQUIRED LIGHT/RESET
SWITCH. NOTE: ORIENTATION OF
SWITCH WILL VARY DEPENDING ON
MODEL

Figure 2-8 Descale Required Light

and Timer Module

13

2). Determining the Timer Setting

The recommended setting of the Descale
Required light is determined by the
quality of the water supply. Table 2-2
suggests appropriate timer settings.

3). Switches Determine Timer Setting

The Timer Module contains a bank of
miniature switches that determine the
timer setting. The switches can be placed
in either the ON or OFF positions.

Each switch has a specific value. The
total timer setting is the sum of the values
of all of the switches that are in the ON
position. (See Figure 2-9 for switch
values).

The Descale Required Light timer is
preset at the factory with switches 1 and
2 turned ON. Adding the values of these
switches results in a setting of 384 hours
(128+256=384).

4). Procedure to Change Descale Required Light Timer Switch Settings

Read this procedure completely before starting. The Descale Required Light Timer setting
should be changed only by qualified maintenance technicians familiar with electrical safety
procedures.

a) Make sure all power to the unit is OFF.

Disconnect the electrical power before servicing.

c. Install Water Supply Lines

The installer/owner is responsible for the correct water connection of the unit. When connecting the
water supply lines observe the following instructions and all national and local codes and
regulations:

1). Never

connect the unit to HOT WATER. The condenser system of the steamer will not work

properly if it is connected to HOT or WARM water.

2). The water supply should have a minimum flow pressure of 35-psi (2.4 kg/cm²) and a maximum
static pressure of 60-psi (4.1 kg/cm²). If the static pressure is above 60 psi, a pressure regulator
must be used set at approximately 50 psi. Pressure above 60 psi can damage the solenoid
valves.

3). The Gemini Steamers are supplied with two connection points for incoming water, one feeds
the condensers and the second supplies feed water to the generators. If the local water supply
is of poor quality (see Chapter 2, Section 6, Part a.1 for details of water quality), it is
recommended that treated or otherwise filtered or conditioned water be used to supply the feed
water to the generators. In the case of using a separate water supply, use the layout shown in
Figure 2-11.

4). Pay attention to the following requirements and recommendations when connecting the
steamer to the water supply:

a) Cleveland Range recommends the plumbing layout illustrated in either Figure 2-10, for

installations using a single water supply or Figure 2-11 if a separate conditioned water
supply is being used for boiler feed. Note: If using a single water feed to the system the
supply piping to the tee fitting should be of at least the next largest size of pipe to the
connection provided at the steamer.

b) The steamer has two 3/8-inch IPS fittings (Model 24CGA6.2) or two 1/4-inch IPS fittings

(Model 24CGA10.2) for the water connections to the generator and to the condenser.
These fittings are detailed as D and E in Figure 2-1 or 2-2.

c) Install a manual water valve between the main cold water supply line(s) and the steamer

supply lines.

d) The National Sanitation Foundation (NSF) requires installation of a check-valve in all supply

lines in accordance with and as required by local plumbing codes.

e) The water supply line(s) should be designed so that the unit can be moved for service.

2. Burner Ignition Test (Lighting and Shutdown Instructions)

It is recommended that this test be performed before beginning the Startup Test Procedure. This will
insure that the basic heating system is operating normally before reviewing the overall operation of
the steamer, since much of the operation is dependant on the operation of the burner control system.

a. Lighting Instructions

This is a functional test of the intermittent pilot ignition system. Pilot/burner ignition is completely
automatic.

NOTE: Each compartment has its own steam generator and control system, and must be started

1). If not already done during prior installation or testing:

2). The controls should be set as follows:

3). Turn ON the electrical power to the steamer at the main power switch.

4). Turn ON the electrical power to the steamer at the ON/OFF levers/switches.

DO NOT TRY TO LIGHT THE BURNERS OR PILOT WITH A FLAME.
The Gemini has an electronic ignition system, which automatically lights the
pilot and burners, senses the flame, and controls gas flow. This provides
precise burner control, safety ignition, and shutdown features.
DEATH, INJURY OR EQUIPMENT DAMAGE may result from an improperly
adjusted gas control and ignition system. Do not alter any adjustments on this
electronic control or automatic gas valve.
If adjustment is required, contact an authorized service center. Cleveland
Range is in no way responsible for the operation or safety of this equipment if
the controller, valve or igniter probe is adjusted by anyone other than a
Cleveland Range authorized service representative.

Test the water supply lines.

·

Leak test the gas supply lines.

·

Check that the ON/OFF valve of the automatic gas control valve is in the ON position.

·

Turn the Main Manual gas valve to the open position.

·

The main power switch should be in the OFF position.

·

The steamer’s ON/OFF levers/switches should be set to the OFF position.

·

The MANUAL/TIMED switches should be set to the TIMED position.

NOTE: When initial power is supplied to the steamer with the ON/OFF lever/switch in the

when the 3 minutes have elapsed or the ON/OFF lever/switch is changed to the
ON position.

WARNING

18

b) After 2 to 3 minutes, water reaches the middle probe (safety level).
c) Turn on a cooking compartment (for non-”Instant ON” units only) and the burners will light

with a distinctive sound. NOTE: Cooking compartment doors must be closed first.

¨

If the burners light within 5 minutes of turning the unit ON, the ignition controls are
functioning normally. End this test procedure here.

¨

If the burners do not light within 7 minutes, there may be air in the gas supply lines
proceed to step 5.

5). Turn off electrical power to the Steamer, at both the ON/OFF levers/switches and the main
power switch.

NOTE: When the burners fail to ignite, a safety circuit in the igniter control de-energizes

the system and closes the automatic gas valve. The safety circuit resets when
the steamer’s power is turned OFF and then back ON.

6). Wait 5 minutes and then repeat steps 2 through 6. If this is a brand new installation, or an
excessive amount of air in the lines is suspected for any other reason, it may be necessary to
bleed the excess air from the lines. This should be done at a union or connection as close as
possible to the inlet of the automatic gas valve.

7). If the burner does not light after the third attempt, call a Cleveland Range authorized service
representative to adjust the burner controls.

8). Go to Shutdown Instructions.

b. Shutdown Instructions

1). Turn off electrical power to the steamer, at both the ON/OFF levers/switches and the main
power switch.

2). Turn off gas supply at the main manual gas valve.

3. Start up Test Procedure Gas Gemini

Cleveland Range steamers have either a manual dial timer control panel, an electronic control panel with a
keypad timer control, an “Instant ON” control system (available only for the Gemini 6 pan model) or an
ON/OFF control panel. There are a few operating differences between steamers with the dial timer controls
and steamers with the keypad controls.

The differences in cooking operation of the two types of timer controls are fully explained in the separate
OPERATORS MANUAL. The “Instant ON” model has no operating controls other than the Power ON/OFF
lever, and begins heating to produce steam as soon as the ON/OFF lever is set to the ON position. The
ON/OFF Control Panel, operates exactly like the manual operation of the timed models except a selector
switch is used to turn the steam to the cooking compartments ON and OFF. After performing the startup
procedure, perform the test procedure as appropriate to the control panel on the steamer being tested.
Ignore any steps, which do not apply to the steamer being tested.

This procedure is appropriate for steamers with keypad control panels, dial timer control panels, “Instant
ON” or manual control panels. Read through all steps of this procedure before starting. Complete the startup
procedure before starting the actual operating tests. This procedure should be performed only by a

service technician or installer.

NOTE: Each compartment has its own steam generator and control system, and must be started

independently.

19

a. Startup Procedure

1. Check that the water supply line valves are open.

2. Check that the main manual gas valve is open.

3. Open the steamer door. Check for proper installation of the drain screen, slide racks, and door
gasket assembly. Be sure the drain is not blocked. Shut the steamer door.

4. Refer to electrical layout, Figure 2-6, and Figure 2-1 or 2-2. Be sure the main power switch is in
the OFF position. Verify installation of the proper size fuses or circuit breakers.

5. Set the control panels as follows:
a) Set the ON/OFF levers/switches to the OFF position.

b) Press the TIMED (top) end of the TIMED/MANUAL switch for both compartments.

c) The timer setting is not important while the ON/OFF lever/switch is in the OFF position.

·

The keypad timer display is blank without power.

·

Even if the timer is not zeroed, the timing circuits are not powered.

6. Remove the right side access covers (see Figure 1-2 or 1-3).

·

Check for plumbing leaks.

·

Look at the one-inch vent gap between the steamer drainpipe and the floor drain. A steady
stream of water should be draining from the steamer.

·

NOTE: The ON/OFF lever must be turned fully to the OFF position to START the proper
blowdown sequence.

·

After about 3 minutes, the cycle is complete. Check the gap at the steam drain; there
should be no more water flow at this point.

steamer soon.

WARNING

20

c. Operating Tests and Final Checkout Procedure (Continue from Blowdown Inspection)

(Sequence of Operation)

1). At the start of this test the controls should be set as follows:

2). Set both the upper and lower compartment timers to zero.

When checking inside the steamer always open the door slowly
and stand to the side and back away from the steamer. Water
leaking from the door gasket can be a sign of a blocked drain. If
the drain is blocked, hot water can accumulate inside the
compartment and spill out when the door is opened.

·

The main power switch is ON.

·

The ON/OFF levers/switches are OFF (The red indicators on the control panels are not lit).

·

The TIMED/MANUAL switch is in the TIMED position. (or for ON/OFF models the ON/OFF
compartment selector switch is in the OFF position)

·

The timer display will be blank while the ON/OFF lever/switch is set to OFF. [key pad
models]

a). KEYPAD MODELS

If the timer is not zeroed (00:00) when power is turned on in step 3, press and hold the
CLEAR key on the key pad control panel to zero the timer.

WARNING

b). DIAL TIMER MODELS

If the Timer is not zeroed, turn the dial counter clockwise until it points to the 0 mark.

3). Set the ON/OFF lever/switch to the ON position. As the steam generator fills with water, check
the following functions.

a). The red ON/OFF indicator light turns ON. The fill valve opens and water begins to fill the

steam generator. The combustion blower turns on to purge the combustion chamber.

b). After a few minutes, water appears in the bottom of the probe cylinder. As the water level in

the steam generator rises;

¨

Check that no water flows from the drain opening.

¨

Check for plumbing leaks.

4). When the water in the steam generator reaches a safe operating level (which is the level of the
middle probe), the combustion blower shuts off and the pilot ignition cycle starts. The steam
generator begins to heat the water to stand-by temperature by lighting the pilot/standby burner.

a) Water continues to fill the generator and the water level in the probe cylinder continues to

rise.

b) The water in the probe cylinder stops rising, when water reaches the upper probe.

¨

If the water level continues to rise above the tip of the higher probe, have a qualified
service representative check the probe circuit.

5). Set the TIMED/MANUAL switches of both compartments to MANUAL (or for ON/OFF Models
set the compartment selector switches to ON), the steaming cycle starts. Check the following
functions.

·

If the water level in the steam generator is above the lower probe, the heating components
turn ON and begin to heat the water to steam. (For mechanical timer models only, the
pause light comes ON)

21

·

After a few minutes steam begins to enter the compartment from the nozzles. A small
quantity of water may drip from the nozzles until steam clears the lines.

·

After a few more minutes the compartment will reach cooking. The thermostat will close
temperature (the pause light will go OFF for mechanical timer units) and the condenser
solenoid clicks open and condenser flow starts. After a few seconds, a stream of water
flows from the drainpipe. If no drain water flows, check that the water supply valves are
open, and the lines are connected properly.

·

With the unit in manual cooking mode the unit should steam continuously until turned OFF,
or set to the timed cooking mode. After several minutes of steaming, check for steam leaks
around the door gasket.

6). As the unit continues to steam in Manual Cooking Mode, test the no-water/low water safety
circuit.

a) Close the steamers manual water supply valve. Observe the steam generator probe

cylinders while steaming continues.

b) As water steams out of the generator, the water level drops below the low water safety

cutoff point. The steamer should automatically shutoff.

c) Re-open the manual water supply valve. The steamer’s controls automatically refill the

steam generators with water to the safety level and resumes steaming.

7). When the TIMED/MANUAL switch is set to TIMED (and the timer is zeroed), the steam
generating cycle stops. Press the TIMED end of the TIMED/MANUAL switch for both
compartments.

·

The main burners turn OFF, and the condenser flow stops. On DIAL timer models only
the buzzer will sound for 3 seconds.

·

Steam stops entering the cooking compartment.

8). Open the cooking compartment door to vent the steam and allow the compartment to cool
slightly. After 2 or 3 minutes, close the door and continue testing.

9). With the TIMED/MANUAL switches set to TIMED, set the timers of both compartments for 10
minutes.

10). When the START/STOP key is pressed [Keypad Models] or as soon as the dial is set [Dial
timer Models], the steam generating cycle starts. This is the same sequence observed in steps
5 and 7, except:

·

The timer controls the cycle.

·

The elapsed time to produce steam is shorter because the water in the steam generator
and the cooking compartment were preheated during step 5.

·

The timer automatically starts the step 7 functions after counting down to zero.

11). After the timed operation has been started, observe the following steam generating functions.

a) KEYPAD CONTROL

The timer display changes to PAUS until the cooking compartment reaches cooking
temperature. When it does, the timer begins counting down to zero.

DIAL TIMER CONTROL

The Pause light comes ON until the cooking compartment reaches cooking temperature.
When it does, the timer begins counting down to zero, and the Pause light turns OFF.

b) When the unit reaches temperature the condenser solenoid clicks open and condenser flow

starts. A small stream of water flows from the drainpipe.

22

c) If the probe cylinder water level drops below the upper probe, 15 to 20 seconds later the

water fill valve opens and fills the generator. When the probe cylinder water level is above
the middle probe, the burners turn ON. A dull roaring sound indicates the burners are firing
and the unit is generating steam.

d) As the unit generates steam, the water level fluctuates and a clicking sound is heard as the

solenoid opens and closes the fill valve. The level in the cylinder rises and falls between the
upper and lower fill limit as the fill valve operates.

e) Check for steam leaks around the door.

f) KEYPAD CONTROL

When the timer counts down to zero (00:00), the burners turn OFF, the condenser flow
stops, and the buzzer sounds continuously. Press the START/STOP key to silence the
buzzer.

DIAL TIMER CONTROL

When the timer counts down to zero, the burners turn OFF, the condenser flow stops, and
the buzzer sounds for 3 seconds.

g) After about 30 seconds steam stops entering the cooking compartment.

12). Turn the steamer OFF by turning the ON/OFF lever/switch counterclockwise to the OFF (top)
position. The red indicator light turns OFF immediately, and the automatic blowdown cycle
starts. DO NOT turn OFF the power at the main power switch until blowdown is complete. The
cycle takes about 3 minutes.

13). When blowdown is complete, turn the steamer OFF at the main power switch.

14). Install the side panels and secure them in place with the screws (See Figure 1-2 or 1-3). After
completing the Startup and Blowdown Inspection procedure, and the Operating Test procedure;
the steamer is ready for service. Refer to the separate OPERATORS MANUAL for complete
operating instructions.

CHAPTER 3 PREVENTATIVE MAINTENANCE AND

5. For more information on products and services, contact your nearest Authorized Sales Representative.
Call factory for a preventative maintenance program, descaling kits, descaling information, and water
treatment systems: USA: [phone], Canada: [phone].

6. To evaluate whether a convection steamer is producing normal cooking performance, conduct the Egg
Test as follows (Note: This test is not valid for SteamCubs or pressure steamers). A properly operating
steamer will produce cooked eggs as follows.

Turn on the steamer so that steam is being produced. After steam has begun to enter the compartment,
preheat the compartment by turning the timer on for ten minutes.

After the compartment is preheated:

· Place two fresh eggs in a perforated pan.

· Set timer for 10 minutes and turn ON.

· After five minutes, open door and remove one of the eggs.

· Close the door right away and allow second egg to cook.

· Crack open first egg and it should be soft boiled.

· After timer goes OFF, open door, remove egg and crack open. It should be hard-boiled.

7. Whenever opening door, especially when water or steam is leaking around gasket heed the warning
below.

When checking inside the steamer always open the door slowly
and stand to the side and back away from the steamer. Water
leaking from the door gasket can be a sign of a blocked drain. If
the drain is blocked, hot water can accumulate inside the
compartment and spill out when the door is opened.
