delime the platen as frequently as once a week.
— Clean/delime the water tube.
Warranty
— Two-years parts and labor.
— Items not covered under warranty:
— Water tubes.
— Abuse to unit, including bent covers and spatulas.
Operation Tips

Water Tube Cleaning
In areas that have very hard water conditions, scale can accumulate in the water tube, preventing proper water dispensing. Thus, the water tube should
be cleaned during the deliming process as well as during the daily cleaning. It is recommended that the steamers go through a deliming procedure once
a month. Some hard water areas may require daily, weekly, or biweekly deliming based on actual buildup.
Turn unit off and unplug the power cord from the electrical
receptacle. Proceed with caution. The unit is still hot.
Items needed:
— McDonald’s Delimer
— Insulated gloves
— Steamer brushes
WARNING
Immediately after turning off the unit, prepare the deliming
solution. Add one packet of McD Delimer to 16 ounces of warm
water. To ensure that all of the delimer dissolves, stir solution
vigorously. Remove top cover, venturi plate, spatula and top plate.
These pieces are hot.
Pour the Delimer into the steam chamber.
WARNING
1
Let solution soak on the platen for five minutes.
While deliming the platen, dampen the bristles of the brush by
dipping it in delimer solution.
2
Insert and remove the steamer brush into and out of the water
tube to disintegrate any scale build up in the tube. Insert the
pipe cleaner at least 1 inch into the tube.
Repeat for 30 seconds.
The platen is still hot!
CAUTION
3
If the tube is severely clogged, the tube will need to be removed
from the unit and replaced. Refer to Water Tube Replacement
instructions.

Water Tube Replacement
Stores that have harder water in their areas may experience scale buildup in their water tubes, thus clogging the tube and preventing water from being
dispensed into the steaming chamber. If the tube needs to be replaced, this sheet will illustrate how to replace the water tube.
First, turn off and unplug steamer. Let steamer cool down. To
remove the rear cover plate that shields the water tube, use a
Phillips head screwdriver to remove the two screws. Next, take
off the rear cover plate to access the water tube.

To pull the tube out from the water valve, push in the grey disk on
the water valve and then slowly slide the tube from the water
valve.
Grey disk is here —
at end of valve
2
Using pliers, gently pull the tube out from the platen. You may
need to softly rock it back and forth. Replace the black insulating
bushing if the original bushing pulled out with the water tube. All
units must have a bushing installed. To reinstall the bushing,
lubricate it with water and push it back into the opening.
Platen must be cool.
CAUTION
3
To insert the new tube, first insert the top end through the hole
that leads to the platen. The tube will fit through the insulating
bushing.
4
Push the other end of the tube into the water valve. Ensure that
you feel it click into place. Gently tug on the water tube to check if
it is secure. If the tube slides out, reinstall the tube. If tube is
improperly installed, water will leak at this point.
5
Finally, reinstall the rear cover plate. Turn on unit and begin a
water cycle to check for leaking at the water valve. If leaking
occurs at the back panel of the steamer, turn off unit and repeat
Step 5.

Daily Cleaning
1. Turn the steamer power On/Off switch to the OFF position and unplug
the steamer from the power source. “PROCEED WITH CAUTION” —
CAUTION UNIT IS STILL HOT.
2. While wearing protective gloves, remove the top cover, top cover plate
and venturi plate and wash in a solution of McD®APSC/APC made
up in the back sink. Rinse with clean water, sanitize with McD®Sink
Pak Sanitizer (KAYQUAT®), and air dry.
3. Wipe the steam chamber surface with a clean sanitized towel.
4. If the surface shows signs of excessive calcium and lime buildup,
dissolve two teaspoons of McD®Delimer™ in a small coffee cup with
100 ml of water. Pour half on each side.
5. Use the steamer brush to clean the water tube. Dip the brush in warm
water (or delimer if completing Step 4). Insert the brush about 1" into
the water tube. Scrub for 30 seconds.
6. Using a clean sanitized towel wipe the internal surfaces of the steam
chamber to remove any debris or delimer.
7. Wash all external surfaces of the steamer with a solution of McD®
APSC at the back sink. Using the McD®APSC spray bottle, spray
directly onto a clean sanitized towel and wipe the unit clean.
DO NOT SPRAY DIRECTLY ON THE UNIT OR USE ABRASIVE
CLEANERS.
8. Reassemble the steamer.
9. Turn unit on. When unit is preheated, run a minimum of four cycles to
prime the unit and remove any residual cleaner.
It is recommended that the steamer be delimed once a month. Some
hard water areas may require daily, weekly, or biweekly deliming
based upon actual buildup. Continued water problems may require
further water treatment (use of the CUNO RO System FSTM035).
With use of the CUNO RO System FSTM035, deliming is
recommended once a month.
