Figure 4. Connecting Water Supply
INSTALLATION (continued)
Plumbing
NOTE: Miracle Steamer models are designed to
use cold tap water. Distilled water may be used to
reduce calcium/mineral deposit buildup and reduce
maintenance costs.
These units require a direct cold water hookup. A Water
Inlet Hose and Strainer Assembly (Figure 4) is supplied.
NOTE: Incoming water is controlled by a normally
closed (NC) solenoid valve located inside the
Steamer’s electrical housing.
1. Turn off the water valve (not supplied) that sup-
plies water to the unit (Figure 4).
2. Connect the 1/4” (6.5 mm) I.D. Flexible Tubing to
the outlet side of the Water Pressure Regulator
and secure using the Worm Clamp (Figure 4).
NOTE: A Water Pressure Regulator must first be
installed (Figure 4). Failure to do so will result
in poor steaming and possible flooding. For a
single steamer, use Water Pressure Regulator P/N
7000314.Fortwoadjacentsteamers,useWater
Pressure Regulator P/N 7000235.
CAUTION
Water pressure must not exceed 30 psi (2.1 kg/cm2
or 207 kPa). Higher pressure may cause poor per-
formance or flooding. To reduce water pressure,
install a Water Pressure Regulator, and set to
20–25 psi (1.4–1.7 kg/cm2or 138–172 kPa).
3. Turn the water valve on.
4. Hold the Quick Disconnect Insert over a bucket,
then press and hold the white plastic tip until
there’s a good, steady water flow. This will purge
all air out of the line.
5. Release the plastic tip and check the pressure on
the Water Pressure Regulator. It should read
20 psi.
a.) If it reads less, increase the water pressure by
pulling the black knob up and turning it clockwise.
b.) If it reads more, decrease the water pressure
by pulling the black knob up and turning it counter
clockwise.
NOTE:Whenadjustingtheknob,relievetheexist-
ing pressure by pressing the plastic tip on the
Quick Disconnect Insert for 3 seconds. The Water
Pressure Regulator will then show the new pressure.
6. Once the regulator reads 20 psi, push the black
knob down to lock it in place.
7. Push the Quick Disconnect Insert into the fitting at
the rear of the unit until it clicks (Figure 4).

CYC (Total Cycle Time) refers to the total pro-
grammed steam time set for the product.
SHO (Shot Interval Time) refers to the time set
between shots of steam during a complete cycle.
H2O setting (Steam Shot Time) refers to the water
volume consumed during each water pump activation.
The amount of steam produced by your Miracle
Steamer depends on the amount of water sprayed onto
the steam generator.
Flooding of the generator may occur if the H2O setting
is too high. To prevent flooding, the Shot Interval Time
(SHO) can be increased to allow more time for genera-
tor heat recovery. Adjustments should be made to both
values to determine the best settings for your cooking
needs.

asbleach,sanitizers,degreasers,ordetergents)
could cause permanent damage to stainless steel
equipment. The damage is usually in the form of
discoloration, dulling of metal surface finish, pits,
voids, holes, or cracks. This damage is perma-
nent and not covered by warranty. The following
tips are recommended for maintenance of your
stainless steel equipment:
• Always use a soft, damp cloth for cleaning,
rinse with clear water, and wipe dry. When
required, always rub in direction of metal polish
lines.
• Routinecleaningshouldbedonedailyusing
soap, ammonia detergent, and water.
• Stainsandspotsshouldberemovedusinga
vinegar solution.
• Fingermarksandsmearsshouldberubbedoff
using soap and water.
• Hardwaterspotsshouldberemovedusinga
vinegar solution.

7. Using a sponge or a dry towel, remove the
delimer solution from the Generator surface, then
rinse with clean water.
Monthly
The Miracle Steamer utilizes an open steam Generator.
Water sprayed onto the Generator surface flashes into
steam immediately, but the minerals in the water do not
steam, they stay on the Generator surface. A small
amount of calcium/mineral deposits are needed for
proper operation, but a buildup of excessive calcium/
mineral deposits causes poor steaming efficiency and
excessive moisture (wet steam), which will eventually
severely hinder the steaming action.
CLEANING STEAM GENERATOR
1. Turn the power off, unplug the power cord, and
allow the unit to cool down.
2. Perform the Daily cleaning, but do NOT
reassemble the unit.
3. Remove the Wing Nut, Generator Cover, and
Diffuser (Figure 11). Wash these items in hot,
soapy water, rinse and WIPE DRY.
4. With the unit cool, use a wire brush and/or
scraper to loosen and remove the excessive cal-
cium/mineral deposits from the Generator
surface.
5. Take a wire brush and clean out any buildup from
the 28 Steam Ports (26 vertical and 2 horizontal)
of the Generator (Figure 11). Remove the loose
buildup, wipe the Generator with a clean, damp
cloth, and reassemble the unit.
NOTE: If deposits are still excessive and/or diffi-
cult to remove, refer to Steps 6 and 11.
6. Pour delimer solution (not supplied) onto the
Generator surface. Follow the delimer manufac-
turer’s instructions for proper mixture and use.
CAUTION
If a chemical cleaner/delimer is used, be sure it is
safe to use on cast aluminum. Observe all pre-
cautions and warnings on the product label.
MAINTENANCE (continued)
NOTE: To ensure proper steaming characteristics,
some calcium/mineral deposits must be present on
the Generator surface. If, during cleaning, the sur-
face does become free of calcium/mineral deposits,
add plain tap water to the surface and allow it to
boil off. If necessary, repeat this process to formu-
late a thin coating of calcium/mineral deposits.
NOTE: In soft water areas, it may be necessary
to add a small amount of lime to the Generator to
“season” it. This will ensure proper steaming char-
acteristics by producing a thin coating of calcium/
mineral deposits on the Generator surface.
Seasoning mixture consists of 3/4 ounces (25ml/
25cc) baking soda, 3/4 ounces (25ml/25cc) lime
mixed with 1 quart (950ml/950cc) of water. Stir
mixture and pour 1/4” deep onto the hot Generator
surface. After mixture is converted to steam, the
remaining loose power can be removed.
8. Plug the power cord into the appropriate outlet.
9. Turn the power on and allow the unit to warm up
for approximately 30 minutes.
10. Push and release the OPERATE button or the
START/STOP button several times to operate the
steamer. This purges any remaining delimer
residue from the Generator surface.
11. Turn the power off, reinstall all parts and acces-
sories, and return the unit to service.

CHECKING AND CLEANING THE WATER STRAINER
The Water Strainer protects your equipment from any
foreign debris in the water line that could get into the
food or damage the unit’s solenoid and cause the unit
to leak or flood. It also protects the equipment’s proper
and consistent operation from interference.
To ensure proper and consistent steaming results,
check the Water Pressure Regulator and Strainer
Cup regularly. If the pressure has dropped, check the
Strainer Cup and clean out the accumulated debris as
follows.
1. Shut off the water supply valve to the unit,
unscrew the clear, plastic Strainer Cup and care-
fully remove the Mesh Screen.
2. At the sink, gently flush all of the accumulated
debris from the Strainer Cup and Mesh Screen.
Be especially careful not to damage the Mesh
Screen.
MAINTENANCE (continued)
Mesh
Screen
O-ring
3 Carefully place the Mesh Screen into its seat at
the bottom of the Strainer Cup and confirm that
the orange O-ring is properly seated in its place
before screwing the Strainer Cup and top back
together.
4. Purge the air out of the strainer and tubing by
disconnecting the Male Quick Disconnect Insert
from the equipment and, over a bucket, push the
white plastic tip in until there is good water flow.
5. Replace damaged or worn parts as needed.
6. Verify that the Water Pressure Regulator is set to
20–25 psi (1.4–1.7 kg/cm2or 138–172 kPa).
