SET Safe-NET TIME
Safe-NET is the electronic controller that
regulates the cooling system. Before Safe-NET
can operate correctly, the internal clock must
be set. This will allow it to regulate the system
for defrost at convenient times of the day
around your location’s schedule — when you
are not at the busiest serving times.
The Chill Chamber’s Safe-NET comes preset
with two defrosts per day. In most situations
this will be enough defrosts unless the unit is
operated in non-air conditioned environments
or high humidity locations.
The Safe-NET on the MAXI-140 is located
behind the back grille below the condenser coil.
When you plug in the Chill Chamber you
should see the text “Safe-NET” scroll across
the display.
• Open the Safe-NET controller using a small
flat blade screwdriver to pop off the oval cover
(this may be tight).
• Plug in the MAXI-140. Be careful of
moving parts in the compressor compartment.
• You will see three buttons on the control
board as shown in this photo.
The SELECT button is used to scroll through
menus, and to edit/confirm values. Use the UP
or DOWN button to move to the next item in
the menu or change the value of a parameter.
Three Button Rules
• Always start by pushing and releasing the
SELECT button, watch what is displayed.
Which menu are you in?
— StUP — CLOC — DEFr — tEM —
VALv — DiSP — and cycles back to StUP

• Once the display starts blinking you will be
able to select the pass code, 595. Press the
DOWN button to get to this number.
• Once 595 is displayed, press the SELECT
button on the Safe-NET display module. The
display will revert to cycling between PASS and
595. This enables editing of system parameters.
The user may now navigate the menu system
and edit parameters as necessary.
Note:
The pass code protected access remains active
for 5 minutes. Each time a new parameter is
entered by pressing the SELECT button on the
Safe-NET display module, the 5 minute timer is
restarted. After 5 minutes with no parameter
entries, the pass code value reverts to 0 and the
pass code entry process must be performed to
regain access.
Any time you want to change defrost times, you
will need to set up the pass code before being
able to make the necessary changes.
Escape
To leave a Menu and return to the default
display, press the UP and DOWN buttons on
the Safe-NET display module simultaneously.
If a valid pass code has been entered it will
remain active for the remainder of the
5-minute time out period. This allows exiting
one menu and entering another to modify a
value without having to re-enter the pass code.
Defrosts
The unit must go into defrost mode at least
twice in each 24 hours to maintain optimal
performance. During defrost, the temperature
display may move up 2-3°F (1-2°C). Avoid
opening the door during the defrost cycle.
Defrost is necessary because the Chill Chamber
operates at temperatures below freezing (22°F/
–5.5°C). Defrosting is done automatically with
Safe-NET.
Defrost water drains to a drip pan where it
evaporates. Restricting airflow around the
bottom of a Chill Chamber may delay or
prevent complete evaporation.
In the event of power loss, the real time clock
will keep its settings for at least one week once
the battery is fully charged. The real time clock
battery is automatically recharged when the unit
is plugged in.
The Chill Chamber Safe-NET comes with two
defrosts preset: one at 0200 and one at 1400. If
the preset defrost times are acceptable for your
business, no settings need to be changed.
Replace the Safe-NET cover and grille.
If the preset times need to be changed for your
business schedule, or if additional defrosts are
needed because the unit is in an extreme envi-
ronment, the Safe-NET controller can be set to
meet the requirements of your business.
For MAXI-140 defrost, the evaporator fan
motor stops during defrost and WILL NOT
came back on when the compressor kicks on
because it has a delay in order to cool down
the evaporator before blowing air again. The
fan delay is controlled by the temperature of
the coil outlet.

Set Defrost Time (Pass Code Needed)
• Press the SELECT button (top left button)
until you see dEFr.
• Then press the UP button twice to get to
StAr and press SELECT.
• Press the UP or DOWN button to change
minutes; press SELECT.
• Press the UP or DOWN button to change
hours; press SELECT.
The second defrost will follow 12 hours later. If
this change meets the needs of your business,
replace the Safe-NET cover and grille.
Change Standard Defrost Time
(Pass Code Required)
Your business may need defrost times that are
not evenly spaced, or staggered, such as 0300
(3:00 a.m.) and 1400 (2:00 p.m.) because your
business is open later. Or you may need more
than two defrosts due to peak sales or high
humidity—0300, 0900, 1500 and 2100 are
evenly spaced, while 0300, 1000, 2100 are
staggered defrost times. Safe-NET can handle
2 or 3 staggered defrosts or 2 to 8 evenly
spaced defrosts in 24 hours.
NDEF
The ndEF parameter sets the number of defrost
cycles in a 24-hour period. The number works
in conjunction with the StAr parameter
discussed above. The ndEF (number of
defrosts) determines the number of defrosts
that occur in a 24-hour period beginning with
the StAr (first defrost) parameter. The
maximum number of defrosts allowed in a
24-hour period is 8. The defrosts are spaced
evenly across the 24-hour period beginning
with the StAr time. The formula for calculating
defrost start times is as follows:
Defrost interval = 24/ndEF
First defrost cycle start time = StAr
Second start time = StAr + Interval
Third start time = StAr + 2 X Interval
~
Eighth start time = StAr + 7 X Interval
For example, with a StAr value of 01:00 and
an ndEF setting of 4, the defrost cycle start
times are:
1:00 A.M.
7:00 A.M.
1:00 P.M.
7:00 P.M.
This scheme applies to all types of defrosts.
Setting this parameter is done in the dEFr
menu. After navigating to the ndEF submenu
item, the display will cycle between ndEF and
the current setting. While the setting is being
displayed, press the SELECT button to edit
this value. When the Safe-NET display module
begins flashing the value, use the UP /DOWN
buttons to increase or decrease the value to the
desired setting.

Once the desired setting is displayed, press the
SELECT button to store the new value. The
display will revert to cycling between ndEF
and the new value.
If it is necessary to stagger the defrost times to
uneven intervals, select 2-df in the ndEF item.
This enables Str2 in menu which is the second
defrost time, and allows the first and second
defrost times to be set independently. An
example would be 02:00 and 13:00. For three
staggered defrost times, select 3-dF which
enables Str2 and Str3 defrost times.
Defrost should be scheduled for a time imme-
diately following product loading to allow for
the fast pull down.
Replace Safe-NET Cover
Position the cover over the display and gently
press into place.
Run Before Stocking
Allow the Chill Chamber to run at least
30 minutes before stocking.
LOADING
1. Add the maximum quantity (66 bottles)
allowed of Anheuser-Busch aluminum bottles.

OPERATING TIPS
• The unit must be allowed to stand in place for
30 minutes before it is plugged in.
• Once the unit is running, the real time clock
must be set. Once fully charged, the real time
clock’s battery will keep the clock memory for
at least one week.
• In the event of power loss, the real time clock
will keep its settings for at least one week once
the battery is fully charged. The real time clock
battery is rechargeable.
• The unit should run for 30 minutes empty
and must be within 2 degrees of 22 °F before
any product is loaded inside.
• The unit must go into defrost mode twice a
day to maintain optimal performance. During
defrost, the temperature display may move up
2 or 3°F (1 to 1.5°C). Avoid opening the door
during the defrost cycle.
• If the unit is placed in a location that is not
air conditioned or has high ambient humidity,
additional defrost cycles may be required to
prevent the rear refrigeration coil from
blocking with ice.
• Very frequent door openings will eventually
have an impact on product temperature and
cause it to rise. Avoid holding the door open
while deciding on product selection, counting
inventory, etc.
• The large blue LED display above the door
simulates the average temperature of the beer in
the cooler, not the air temperature in the unit.
Therefore, the display temperature will change
slowly as the unit cools down or warms up.
• Unplug the unit before cleaning. Clean the
unit frequently to minimize odors and to main-
tain operating efficiency.
• Do not add warm product.
• Restocked product may freeze.
• Never place product on the bottom of unit.
• Place the lower removable shelf flush against
the back to maintain proper air flow and
product temperature.
• The unit must remain upright at all times.
Do not tilt more than 30 degrees from vertical
at any time.
• The light switch is located on the top right
side of the interior back wall.
• Maintain air flow around the unit at all times.

shipment and applies only to the compressor shipped from the factory with the new product. After year one (1), no
labor is included to replace the compressor.

extended warranty must be purchased and paid for prior to the expiration of the basic warranty coverage. The basic
and extended warranties listed above do not include replacement or repair of controls, relays, capacitors, or over-
load protectors.
