Descaling Procedure-SteamCraft Ultra and Gemini Series

1. Turn the unit OFF and open the

doors:

This will drain and rinse the generator for about

3 minutes.

2. Turn the unit power back On:

The generator will begin to refill with water.

3. Select Timed with the Timed/Manual

switch:

DO NOT start the timer, since you do not want

to heat the water during descaling. Leave the

doors open.

Remove descaling port cap and add

with the specified amount of

DISSLOVE:

(See chart above)

Do this while the unit is refilling. The generators

can take-up to 8 minutes to refill.

After refill has stopped, add extra tap

water into the descaling port until

liquid is seen entering the cooking

cabinet.

Note: Ultra 10 gas will have liquid

coming out of the drain,

Adding extra water when descaling will raise the

descaling solution higher than the normal fill level,

allowing the DISSOLVE to work on sensors and

surfaces above the water line

6. Let the descaler soak in generator for

approximately one hour:

7. After one hour, turn the unit power

Off:

This will drain and rinse the generator

for about 3 minutes.

8. After the 3-minute drain cycle

completes, turn the unit back ON. After

the filling has stopped, add water until

liquid enters the cooking compartment (or

drain for the ultra 10 gas), and then turn

the unit OFF. This will drain and flush any

residue from the water level control

assembly. Replace descaling cap.

After the 3 minute drain cycle

completes, Turn the unit ON and set

the Timer for 20 minutes:

Make sure the

Time/Manual switch is in the timed setting

and the doors are closed.

10. When the timer times out (after 20

minutes) turn the power Off:

This will drain and rinse the generator for

about 3 minutes.

This ends the descaling procedure. You can

now turn the unit back on and resume normal

startup and cooking operations.

How Much DISSOLVE to Use

Model Dissolve

Ultra 3 1/2 Gallon

Ultra 5 1 Gallon

Ultra 10 (Elec.) 1 Gallon (ea.)

Ultra 10 (Gas) 1½ Gallon

Gemini 6 & 10 1 Gallon (ea.)

Note: Some SteamCraft Ultra models (the

electric powered Ultra 10 and Gemini 6 and 10,

for example) have two generators and two

descaling ports. Both units should be descaled

at the same time, using this procedure

CLEVELAND RANGE SEQUENCE OF OPERATIONS 24CGP10 Mechanical Timer 1. To turn the unit on, depress the red on/off rocker switch. • 115 VAC is sent to normally open drain valve closing it. • 115 VAC is sent to the Timed/Manual switches for the cabinets. • 115 VAC is sent to L1 and L2 of the water level board. 2. With the water level board energized and no water in the boiler • 115 VAC is sent from the IND terminal to the low water indicator light on the console.
PAGE 92
• 24VAC is sent from the secondary of the 24 VAC transformer through the low water cutoff float switch to the R2 relay coil. • The normally open R2 contacts close and send 115 VAC to the fan. • The fan turns and the air prover switch is closed. • 24 VAC is sent through the air prover switch to the ignition module. • With 24 VAC to the ignition module a spark is generated at the igniter. • 24VAC is sent to the pilot coil on the gas valve. • The pilot valve is energized and opens.
PAGE 93
• When the steam pressure drops below the operating set point the heat circuit is energized and the heat process begins again. 8. Water continues to fill the boiler until the operational water float is lifted and closes, shorting the HI terminal on the water level board to the C terminal. . • When the HI terminal is shorted to the C terminal the WF terminal on the water level board is de-energized.

• • • • • • The pilot valve is energized and opens. Gas is sent to the pilot burner. The gas is ignited and the flame rectifies the AC current. When the ignition module reads at least 1.0 micro amps DC current through the ground wire the coil to the main gas valve is energized The pilot flame lights the main burner. If the module does not read 1.0 micro amps DC in 90 seconds it will shut down the main burner and make one more try before locking out. 5. The water in the boiler is heated to steam.

• • The normally open contact close when the thermostat reaches 193 degrees. • 115 VAC is sent to the condensate solenoid and cold water is sent to the condensate spray nozzle pulling the steam down the drain.. When the steam pressure drops below the operating set point the heat circuit is energized and the heat process begins again. 11. The unit is turned off by depressing the red rocker switch. • 115 VAC is removed from the timing and heat circuits.

Replacement Instructions Rear Inspection Plate. 1) Start with the unit turned off and completely cool. Before starting this process, verify that the Power switch is in the OFF position, the boiler is completely cool and the pressure gauge adjacent to the power switch is not showing any pressure in the boiler. 2) Remove the Rear Cover Panel (See Figure 1). If the unit being worked on does not have a Rear Cover Panel, remove the rear panel itself.
PAGE 115
WARNING Do not use any method of stud removal such as grinding, which might damage or gouge the boiler face itself. Such damage to the boiler could result in failure of the pressure vessel and cause premature equipment failure, property damage, personal injury and/or death. 7) Remove any excess scale and loose material around the inside and outside of the inspection opening using a scraper and a wire brush (See Figure 3).
PAGE 116
10) Place the gasket over the centering plug of the new inspection cover (See Figure 6). Place the inspection cover with the gasket side down, oriented as shown in Figure 6, onto the boiler brace bolt and start the sealing nut (gasket side down, see Figure 7) provided onto the bolt.
PAGE 117
WARNING Do not over tighten the sealing nut. Over tightening can damage the boiler head and the brace assembly, which may prevent the assembly from sealing and/or cause premature equipment failure, property damage, personal injury and death. Test procedure (See the operating label found on the unit for additional details of the start-up procedure for the boiler) 13) Turn on the main power switch to the boiler, which will fill the unit with water.

11.125 As an alternate, a rectangular opening can be cut out to remove the four louvers shown 11.875 Figure 9 Rear Panel Modification 19) Reinstall any panels that were removed to install the new boiler inspection cover. If your steamer had a rear cover panel installed on the rear sheeting, this can either be left off the unit once the new boiler cover is installed or modified by installing a clearance hole to clear the bolt. See Figure 10. 20) The Steamer is now ready for operation.
