INSTALLATION INSTRUCTIONS

1. These instructions must be retained by the owner/user for
future reference. Gas-fired boilers are only to be installed in
noncombustible areas that have provisions for adequate air
supply. The term "boiler" will be used synonymously with
"steam generator".

2. Position: For proper operation and drainage, the equipment
must be level. It should be placed next to an open floor drain.
DO NOT POSITION THE UNIT DIRECTLY ABOVE THE
FLOOR DRAIN. Observe all clear ance requirements to
provide air supply for proper operation, as well as sufficient
clearance for servicing. The surrounding area must be free
and clear of combustibles. Dimensions and clearance
specifications are shown on the specification sheet.

3. Install in accordance with local codes and/or the National
Electric Code ANSI/NFPA No. 70-1987. Installation in
Canada must be in accordance with the Canadian Electrical
Code CSA Standard C22.1. Equipment that is con-

nected to electricity must be grounded by the installer. A wiring
diagram is provided inside the base cabinet.

WARNING

INJURY TO PERSONNEL AND EQUIPMENT DAMAGE may
result from an improper drain connection.

4. The drain line outlet discharges exhaust steam and hot
condensate. Connect 1-1/2-inch IPS piping (or larger) 10
extend the drain line to a nearby open floor drain. Up 10 two
elbows and six feet of 1-172-inch IPS (or larger) extension
pipe should be connected to the drain termination. Drain
piping extended six to twelve feet, or using three elbows,
should be increased to 2-inch IPS No more than two pieces of
Cleveland Range equipment should be connected to one
common drain line. The maximum length of extension from
the drain termination should not exceed six feet and use no
more than TWO elbows - The extension piping must have a
gravity flow and vent freely to the air. This drain outlet must be
free-vented to avoid the creation of back pressure in the
steamer cooking compartments. To ensure a vented drain
line, DO NOT, UNDER ANY CIRCUMSTANCES, CONNECT
THE DRAIN OUT LET DIRECTLY TO THE FLOOR DRAIN
OR SEWER LINE. Do not run the drain line discharge into
PVC drain piping or any other drain piping material not
capable of sustaining 180°F operation-

NOTE: Direct-steam connected pressure steamers do not require

a cold water connection, and therefore steps 5 and 6 do
not apply. Refer directly to step 7. A kettle fill faucet, if
so equipped, requires a hot and/or cold water
connection The data contained in step 5 for

cold water also applies to hot water.

5. Connect COLD water supply plumbing to the line strainer.
(Never connect hot water to the boiler water fill line strainer.)
Constant flow pressure must be maintained between 35 and
60 psi, and not experience a pressure drop below 35 psi when
other appliances are used. If the water pressure exceeds 60
psi, a pressure reducing valve must be installed in the water
supply plumbing to reduce the water pressure to less than 60
psi- Locations and pressure data are shown on the
specification sheet. 1/4 -inch IPS plumbing is sufficient for
water supply lines up to 20 feet in length, but water supply
lines longer than 20 feet should beat least 3/8 -inch IPS. Flush
water supply lines thoroughly before connecting them to the
unit. Use water which is low in total dissolved solids content
and low in gas content to prevent internal scaling, pitting and
corrosion of the steam generator, and carry-over of minerals
into the steam. Water which is fit to drink can still contain
highly detrimental impurities.

NOTE: If equipped with a kettle and kettle water fill swing

spout, 3/8 -inch (10mm) hot and/or cold water con­nections) will be required at the swing spout valve.

6. Turn on the cold water supply to the unit. Ensure that the
manual water valve, inside the base cabinet, is open.

OPERATION

Operation of the Cleveland Range Convection Pro XVI steamer is very
easy. Each operator should read and understand the following
procedures to effectively start, operate, and shut down the steamer each
day. The owner(s) and operator(s) of this equipment should be aware
that live steam can cause serious injuries, and pay particular attention to
the WARNINGS in this text. These instructions are to be retained by
the owner(s) and operator(s) for future reference.

Controls and Control Panels

There are two steam generator control arrangements and two
steamer compartment control panels available for Cleveland
Range Convection Pro XVI steamers. The steam generator
controls are illustrated in Figure 1. The steamer compartment
control panels are illustrated in Figures 2 and 3. Compare these
figures with the equipment supplied, and identify which control
and panel combinations apply.

Steam Generator Controls

The steam generator controls are located on the front face of the
steamer base unit. The switches are to the left of the pressure
gage, as illustrated in Figure 1. Most Cleveland Range
Convection Pro XVI steamers have a steam generator built into
the base unit which supplies steam to the cooking compartments.
However, an external steam supply may also be used. Units with
a built-in boiler have both the POWER rocker switch and the
STEAM momentary switch next 10 the pressure gage. Units with
an external steam supply have the POWER rocker switch only.
They do not have the STEAM momentary switch.

Steamer Compartment Control Panels

Figure 2 illustrates the standard electronic controls: the Key Pad
Control Panel. This panel has a rocker switch, a key pad, and a
digital timer. Figure 3 illustrates the optional electromechanical
controls: the Dial Timer Control Panel. This panel has a rocker
switch and dial timer. Steamer functions are the same for both
the standard and optional panel configurations. Operating details

Installation, Use and Care Instructions

Convection Pro XVI

CARE AND CLEANING

The Cleveland Convection Pro XVI steamer must be cleaned
regularly to maintain its fast, efficient cooking performance,
and to ensure its continued safe, reliable operation.

1- The boiler must be drained (blowdown) after a maximum of

8 hours of use. If the boiler feedwater contains more than 60
pans per million of total dissolved solids, the boiler must
have a blowdown more often, the frequency depending upon
the mineral content of the feedwater. Blowdown means the
boiler must be drained under pressure.
THE BOILER BLOWDOWN IS PERFORMED BY
SIMPLY SHUTTING OFF THE STEAMER'S RED­LIGHTED POWER SWITCH WHILE THE BOILER IS AT
NORMAL 10 PSI OPERATING PRESSURE-WHEN THE
BOTTOM OF THE POWER ROCKER SWITCH IS
PRESSED, ITS RED LIGHT GOES OUT, AND THE
DRAIN VALVE AUTOMATICALLY OPENS,
DRAINING THE BOILER. AN AUTOMAT ICALLY­TIMED DRAIN WATER CONDENSER WILL FLUSH
THE DRAIN FOR 3 MINUTES, THEN SHUT OFF.
AFTER 3 MINUTES THE STEAMER IS READY TO BE

RESTARTED.
When steam is produced, the water in the boiler is being
distilled. Daring this process, the minerals that come into the
boiler with the water, remain in the boiler as the water boils
away as steam. When allowed to accumulate, the water
becomes hi ghly mineralized, which results in erratic
operation, lime build-up, corrosion, and premature electric
heater failures. In some cases, complete boiler replacement
becomes necessary, which is extremely expensive. By
draining the boiler under pressure, most sediment present will
be flushed down the drain.

2. The steamer is equipped with a drain in the back of the
cooking compartment. No compartment should be operated
without the drain screen in place. This screen prevents large
food panicles from entering and possibly plugging the drain
line. Any restriction of the drain line may cause a slight
build-up of back pressure in the compartment, resulting in
steam leaks around the door gasket. It also may adversely
affect the convection action of the steam in the
compartment, which is critical to optimum performance.
Pouring USDA approved drain cleaner through the
compartment drains once a week will help to ensure an open
drain- A manual (hand crank) drain auger, or "snake", may
be safely used to clear obstructions in the compartment
drains. Do not use a power auger, as damage to the plastic
drain system will result. With the steamer off, open the
cooking compartment doors and allow the steamer to cool
before cleaning the cooking compartments and their
components

3. At the end of each day's operation, wash the pan slides, steam
tubes, door gaskets, and compartment interiors with mild
detergent and warm water, either by hand or in a
dishwasher. Rinse thoroughly with clear water. Rinse water
should drain freely through the compartment drain

openings. If it does not, the dram must be cleaned before
using the steamer.

4. Once a week, remove the steam tubes and clean the orifices.
First, remove the pan slides by lifting upward and toward the
center of the compartment. Pressing backward on the steam
tube will allow its front eyelet to clear the compartment stud.
The tube is then angled toward the center of the compartment
just enough to clear the stud and be pulled forward, out of its
socket- The orifices can be cleaned easily with a paper clip.
Then, thoroughly wash and rinse all steam tubes- This can be
done in a dishwasher. Lubricate each rube's tapered end with
cooking oil before replacing in the steamers compartments.
Be sure all four steam tubes are securely in place before
activating the compartment. The tubes are interchangeable
and may be placed in any spot in either compartment.

5. To prolong door gasket life, always leave compartment door
ajar when not in use.

6. Exterior Care: Allow steamer to cool before washing. Use the
same cleaners and cleaning procedures as for other kitchen
surfaces of stainless steel and aluminum Mild soapy water,
with a clear water rinse, is recommended- Do not allow water
to run into electrical controls. Always turn off equipment
power before using water 10 wash equipment. Do not hose
down the steamer.

WARNING

Do not store or use gasoline or other flammable vapors and
liquids in the vicinity of this or any other appliance.

MAINTENANCE

Periodically, a qualified serviceman should be summoned for
routine preventive maintenance.

1. The blowdown procedure will not completely remove the

mineral deposits that adhere to the top of the boiler - A
chemical descaling should be done by a boiler treatment
specialist. This should be done once a year in average water
conditions, but in poor water areas it may be needed two or
three times a year.

2. Periodic boiler inspection should be made by a qualified
serviceman.

3- Once every three months, the cold water line strainer should

be cleaned.

Cleveland Range supports a comprehensive network of Main­tenance and Repair Centers (regional pans and service dis­tributors) throughout the United States and Canada. Please
contact your nearest distributor for the name of an authorized
service agency in your area, or for replacement pans and
information regarding the proper maintenance and repair of
Cleveland Range equipment. In order to maintain the various
agency safety certifications, only factory-supplied replacement
pans should be used. The use of other than factory-sup-plied
replacement pans will void the warranty.

PRE-INSTRUCTIONS FOR THE LIQUID DESCALING OF

BOILER BASE UNITS

PART NUMBER 106174

Enclosed is our latest instructions for the newest liquid chemical descaler.
Please note: THIS CHEMICAL IS DESIGNED TO BE USED WITHOUT ANY HEAT APPLIED. This
chemical can now be used for the two and three probe boiler base units. Because
the chemical is used without heat, there are some changes in the instructions.
They are as follows:

1. The bottle of our latest liquid descaler has a flip up spout in it like
a shampoo or liquid soap bottle.

2. The design of the bottle and the fact we can not pour the liquid into
the generator through the hand hole plate means you need to build a
special tool. We recommend you use about 24 inches of 1/4" O.D.
flexible tubing attached to a funnel. Remove the needle valve in the
upper sight gauge valve and insert this tube into the generator about
2" inches. Pull the funnel and tubing out front of and above the top
of the generator. Pour the liquid into the funnel.

3. On the right side of the two probe generator is a steam trap. The
bottom connection must be removed and capped so the liquid does not
flow through it.

4. Depending on the style of drain valve and if the unit has a TDS timer,
there are different wiring procedures.

5. The lower compartment steam solenoid valve must be open during the
filling of the generator to allow any air in the top of the generator
to escape.

6. Upon completion of the descale, check the top of the generator to make
sure the chemical has cleaned it.

If there are any questions or problems concerning these procedures, please let
us know right away at 1-800-338-2204.

DESCALE PROCEDURE FOR TWO & THREE PROBE GENERATOR BASE STEAMERS

STEP BY STEP PROCEDURE

IMPORTANT WARNING: BEFORE REMOVING THE HAND HOLE PLATE TO DESCALE ANY STEAM GENERATOR, MAKE SURE
THERE IS NO WATER OR PRESSURE BUILT UP IN THE GENERATOR. CHECK THE OUTER SURFACE OF THE GENERATOR TO
MAKE SURE IT IS COLD. TURN THE YELLOW HANDLE ON THE MANUAL FILL VALVE 90 DEGREES TO THE BODY TO
PREVENT ANY WATER FROM ENTERING THE UNIT. THIS LIQUID DESCALER IS DESIGNED TO BE USED WITH NO HEAT
APPLIED TO THE GENERATOR.

STEP #1

Before opening the hand hole plate in the generator make sure the red power switch is in
the off position. Open the electric circuit box in front of the generator and look for two
black square solid state timers mounted on the side. If there are two solid state timers
in the box, this unit has a TDS blowdown. The timer mounted on top is a one second timer.

1. IF THE UNIT HAS AN ASCO DRAIN SOLENOID VALVE, remove the white wire from the

terminal marked number 3 on the TDS timer to prevent the purge from coming on.

2. IF THE UNIT HAS A PARKER DRAIN SOLENOID VALVE, remove the red/white wire from

the terminal marked number 2 on the TDS timer and attach it to L2 on the
terminal block.

To open the hand hole plate, loosen and remove the nut and bar across the generator
opening. Place the end of a two by four on the hand hole plate. Rap the end of the wood
with a hammer in various places until the plate and gasket fall inside the generator.

Remove any scale build-up that can be taken out by hand or with a small vacuum cleaner. IF
THE GENERATOR HAS PREVIOUSLY BEEN REPLACED WITH A NICKEL PLATED ONE, DO NOT SCRAPE OR
SCRATCH THE SURFACE. Assess the scale build-up above the water level on the tubes and the
top to determine the number of descalings that will be needed.

Use 2 quarts of liquid cleaner regardless of the size of the boiler. If there is a heavy
build-up of scale (1/4" or more) on the upper tubes (above the water level) and across the
top of the generator, it will have to be descaled twice.

After removing the scale and determining the number of descalings needed, replace the hand
hole plate with the old gasket still on the plate.

Because the chemical is designed to work with no heat applied, the
steam trap on the right side of the new two probe boiler must be closed. Remove the bottom fitting and cap
the outlet side.

STEP #2
Remove the needle valve from the top of the sight gauge located on the front of the generator. This will be the

port of entry for the liquid descaling agent. REMEMBER TO MOVE THE YELLOW HANDLE ON THE WATER
FILL VALVE TO ALIGN WITH THE VALVE BODY. Before applying the descaler, turn on the power switch to
close the drain valve. This will also energize the fill valve.

STEP #3
Using the special funnel and tubing you assembled, squeeze the liquid into the generator through the port the

needle valve was removed from
STEP #4
After the descaling agent has been introduced into the generator, replace the needle valve.

1. Place the lower compartment timer switch in the manual position. As the generator is filling with water,

this will allow any air in the top to escape.

2. To completely fill the generator with water, bypass the water level probe:

a. Remove the black wire at the terminal marked HI on the

water level control board that connects to the water
level probe. b. When the water begins to enter the lower cooking
compartment, CAREFULLY replace the black wire on the
water level control. This will turn the water off.

3. Turn the lower compartment switch back to the timed setting. STEP #5

DO NOT PRESS THE AMBER STEAM SWITCH. THIS CHEMICAL WORKS BEST WHEN HEAT IS NOT APPLIED.
STEP #6

Wait one hour to allow for descaling of the generator. Drain the generator by turning off the red POWER
switch. The drain and fresh water solenoid valves will open for three minutes allowing the generator to flush
out. After draining, fill the generator with fresh water and repeat the flush process by turning off the power
switch.

STEP #7

After the generator has been rinsed out, remove the hand hole plate and gasket as explained in STEP #1
Observe the edges and surfaces of the hand hole and the plate for excessive wear and corrosion. Replace the
used hand hole plate gasket with a new one and install new corrosion resistors.

For the corrosion resistors to work properly, the hanger must be firmly connected to the support rod. Make
sure no scale or debris is between the support and the hanger. It must be a metal to metal connection. There
are some two probe generators with no support rods. Lay the corrosion resistors on the floor of the generator.
If the generator is an electric and there are no support rods do not leave the resistors in it. They may come to
rest against the elements and ground them out.

Do not use a gasket sealing material on the hand hole plate gasket. When tightening the nut on the bar, make
sure that at least 1/16" of gasket material is showing on the hand hole plate around the inside of the hand hole.

Reinstall the wire removed from the purge timer in the electric box.

STEP #8

Bring the steamer up to pressure by pressing the red power switch to fill the generator and then the amber
switch when the light comes on. After twenty (20) minutes the generator should have steam in it. Check for
steam leaks around the hand hole. If any leaks are found repeat the process for replacing the gasket.

WATER LEVEL CONTROL SYSTEM

TROUBLESHOOTING AND REPAIR

General Description of Operation:

The Cleveland Range water level control, P/N 23198, is designed to maintain operating
water level in Cleveland Range steam generators and to ensure that the heat source is
only operated when the generator water level is above a specified minimum level. The
sensing technique for the control relies on the fact that tap water is conductive to
electricity; if two metal electrodes are immersed in a bath of water, electric current
can flow between the electrodes using the water as a conductor. Water is not a good
conductor, like copper, but is conductive enough to be measured using appropriate
electronic circuitry.

The Cleveland Range control is a two probe system having two metallic probes (LOW and
HI) for sensing water in the generator; a COM terminal is placed on the tank. The LOW
probe is placed so that it will come in contact with the water when the water level is
just above the desired water level, enough to protect the heat source. If the water
is of sufficient level and the LOW probe is in the water, a small electrical current
provided by the level control electronics will flow between the probe and COM; this
flow will be sensed by the electronics which in turn will activate the "HEAT" relay to
apply AC power to the HEAT terminal on the control circuit board.

Similarly, the HI probe is located at the desired water level fill (above the LOW
probe level) so that when the water level has reached the desired fill level
electrical current will flow between the HI probe and COM. The action of this probe
is reversed from the previous situation so that when water reaches the HI probe, the
WATER fill relay is deactivated so that AC power to the WF is turned off. When the
water level drops below the HI probe, the WF terminal will be reenergized after a five
second delay. The time delay is to prevent bubbling or turbulence in the generator
from chattering to WATER fill relay or the water valve solenoid.

The control runs on 120 vac and is transformer isolated so that the probes and the
electronics are run at low voltage and are not common to the AC power line.

Note that in many Cleveland Range generators both sensing probes are inserted from the
front top of the unit down into the generator. In this case, the LOW probe will be
the longest and the HI probe will be the shortest.
