Warranty
LABOR COVERAGE
Labor to replace any defective part is not included.
PARTS COVERAGE:
Sachet packets and batteries are excluded from the
warranty.
Parts that contain defects in material or workmanship
are covered for a period of one (1) year under normal
use and service.
EXCLUSIONS
The following items are not included in part warranty
coverage:
Damage from improper installation, misuse or abuse,
unauthorized modifications, acts of God, or lack of
normal maintenance.
This product is intended exclusively for commercial
application. No warranty is extended for personal,
family, or household purposes.
General Information
Slime is a leading cause of ice machine breakdowns
and biological growth is a health concern.
Manitowoc’s Guardian System releases chlorine
dioxide on a controlled basis to inhibit the growth of
bacteria and fungi that form slime and cause malodors
in the food zone of ice machines.
The ice machine and bin/dispenser must be cleaned
and sanitized before initial installation of the Guardian
system. The GSI200 will not control mineral or other
water borne buildup. Your water quality will
determine the length of time before mineral buildup
affects ice machine performance. Mineral buildup
must be removed as often as necessary to ensure
trouble-free operation of the ice machine.

ICE SENTRYSACHET REPLACEMENT
FREQUENCY
Ice SentrySachet packet(s) require replacement
every thirty (30) days or whenever they come in direct
contact with water. Refer to chart below for
requirements.

600 800 1000
1300 1600 1800 Use 1 or 2*
*Although one Ice Sentrysachet is recommended,
extreme conditions may necessitate using two sachet
packets.
A green light will blink once every 7 seconds for 30
days. After thirty (30) days the green light de-
energizes and a red light energizes and blinks every 4
seconds. The red light indicates that the Ice Sentry
sachet packet(s) are due for replacement.
The timer receives power from two (2) AA batteries.
Battery life is approximately three (3) years.
A reset button is located on the rear of the timer
housing. After replacing the Ice Sentrysachet
packet(s), press and hold the button for 3 seconds to
reset the 30-day timer, then release the button.
Ice SentrySachet replacement packets are available
through your local Manitowoc ice machine dealer.
ICE SENTRYSACHET REPLACEMENT
PROCEDURE
The size of the refill Ice Sentrysachet required is
based on the amount of ice produced and depends
upon the actual conditions of use. Most applications
require one 200-gram Ice Sentrysachet; extreme
conditions may necessitate two Ice Sentrysachets.
1. Remove front panel from ice machine.
2. Remove and discard spent Ice Sentrysachet
packets.
3. Remove Ice Sentrysachet from foil package and
install into holder. Removing the foil packet
allows the moisture in the air to activate the packet
contents.
4. A reset button is located on the rear of the timer
housing. After replacing the sachet packet(s),
press and hold the button for 3 seconds to reset the
30-day timer, then release the button. The green
light will blink every 7 seconds for another 30 day
period.
5. Reinstall ice machine front panel.
6. Discard used Ice Sentrysachet in trash.
CLEAN UP PROCEDURE FOR DAMAGED
SACHET PACKET
1. Remove all ice from bin/dispenser and discard.
2. Initiate a cleaning and sanitizing sequence on the
ice machine (refer to Ice Machine Installation, Use
and Care Manual).
3. Clean the bin/dispenser. Flush the drain
thoroughly to prevent future drain blockage.
4. Sanitize the bin/dispenser.
5. Install a replacement sachet packet and reinstall all
covers.

rear cover is installed. Snapping the control board
under all four legs will correctly position the control
board.
2. Verify the small key slots are on the right side
when viewed from the front of the timer housing.
Align sachet holder mounting plate holes with
pins in the timer cover housing and snap into
place.
3. Use four pan head screws to secure the back
cover/sachet mounting plate to the timer housing.
4. Attach sachet holder to mounting plate.
Final assembly will be with sachet holder opening
facing up.
a. Rotate sachet holder 90°clockwise.
b. Refer to table to determine if upper or lower
keyhole slots are used. Place left side pin in
the sachet mounting plate keyhole.
c. Rotate sachet holder 90°counterclockwise and
place right side pin in keyhole slot.
d. Push sachet holder down into keyhole slots to
secure.

GSI200 will be offset ½” (1.27 cm) on the front panel.
Measure 6.0” (15 cm) left and 7.0 (17.8 cm) right of center.
Verify the ice machine control box cover screw aligns with a
slot in the sachet holder. This prevents bulging of the front
panel.QuietQubeModels IB600C/IB800C/IB1000C
GSI200 will be offset 3.5” (8.9 cm) to the left on the front
panel. Measure 10.0” (25.4 cm) left and 3.0 (7.6 cm) right of
center. Verify the GSI200 does not interfere with the water
curtain (at the ice thickness probe).
8. Remove backing from double-sided tape on the
bottom of the timer housing.
9. Locate the timer housing on the front panel where
the foam tape was removed in step 7, then press to
seal tape.
10. Mark and drill four 3/32” pilot holes (two on top,
two at rear). Secure timer to front cover with
screws.
Top - Use two pan head screws
Rear – Use two flat head screws
