LOCATION  
CAUTION  
!
Chill Chambers are designed for a protected  
environment, out of direct sun or rain. Placing  
the unit near heat sources (ovens, grills, etc.) or  
in direct sun will adversely affect performance.  
Unusual ambient conditions can be handled by  
changing settings in the Safe-NET controller.  
Temperatures of 80°F (27°C) and less than  
55% R.H. are considered normal ambient  
conditions.  
To reduce the risk of fire, electrical shock or  
injury when using your Chill Chamber:  
• Always use a dedicated circuit with the  
Amperage stated on the unit.  
• Plug into an outlet designed for the plug.  
• Do not use an adapter.  
• Do not overload the circuit.  
• Disconnect power before servicing.  
• Replace any damaged power cord.  
• Never turn off by pulling on the power cord.  
• Unit must have electrical ground at all times.  
• Never connect the ground wire directly to the  
neutral wire or connect to gas, water,  
telephone, drain pipe, lightning rod, etc.  
• Do not damage the refrigeration system.  
• Do not use any mechanical device or other  
means to speed the defrost process, except  
as recommended by the manufacturer.  
The merchandiser will not operate properly  
in environments of extreme temperature and  
humidity [above 80°F (27°C) and 55% relative  
humidity]. Performance issues resulting from  
poor local conditions are out-of-warranty.  
The merchandiser must have a minimum 5-inch  
(13 cm) ventilation space at the back, on each

when the merchandiser is used in high relative  
humidity. Use a soft cloth to remove moisture.  
UNCRATE  
Use the appropriate equipment to safely lift  
and move the Chill Chamber to the preferred  
location in your business.  
The floor or counter must be flat to facilitate  
leveling and to avoid problems with door seal-  
ing or abnormal noises. The floor, or counter,  
must support the weight of a fully loaded  
Chill Chamber. A fully loaded MAXI-140  
weighs about 210 lb (95-kg).  
Carefully remove the shipping box. Avoid  
scratching the Chill Chamber.  
Recycle packing materials whenever possible.  
INSPECTION  
Remove Shipping Legs so the MAXI-140 Chill  
Chamber base can be sealed to counter.  
All equipment should be thoroughly examined  
for shipping damage before and during the  
unloading.  
Each Chill Chamber is carefully inspected at  
our factory. Any claim for loss or damage must  
be made to the carrier. The carrier will provide  
any necessary inspection reports and/or claim  
forms.

SET Safe-NET TIME  
When you plug in the Chill Chamber you  
should see the text “Safe-NET” scroll across  
the display.  
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.  
• Open the Safe-NET controller using a small  
flat blade screwdriver to pop off the oval cover  
(this may be tight).  
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.  
• Plug in the MAXI-140. Be careful of  
moving parts in the compressor compartment.

• Once the display starts blinking you will be  
able to select the pass code, 595. Press the  
DOWN button to get to this number.  
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.  
• 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.  
Defrost is necessary because the Chill Chamber  
operates at temperatures below freezing (22°F/  
–5.5°C). Defrosting is done automatically with  
Safe-NET.  
The user may now navigate the menu system  
and edit parameters as necessary.  
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.  
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.  
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.  
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.  
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.  
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:  
• Then press the UP button twice to get to  
StAr and press SELECT.  
Defrost interval = 24/ndEF  
First defrost cycle start time = StAr  
Second start time = StAr + Interval  
Third start time = StAr + 2 X Interval  
~
• Press the UP or DOWN button to change  
minutes; press SELECT.  
Eighth start time = StAr + 7 X Interval  
• Press the UP or DOWN button to change  
hours; press SELECT.  
For example, with a StAr value of 01:00 and  
an ndEF setting of 4, the defrost cycle start  
The second defrost will follow 12 hours later. If  
this change meets the needs of your business,  
replace the Safe-NET cover and grille.  
times are:  
1:00 A.M.  
7:00 A.M.  
1:00 P.M.  
Change Standard Defrost Time  
7:00 P.M.  
(Pass Code Required)  
This scheme applies to all types of defrosts.  
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.  
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.

display will revert to cycling between ndEF  
and the new value.  
LOADING  
1. Add the maximum quantity (66 bottles)  
allowed of Anheuser-Busch aluminum bottles.  
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.  
2. Load the product after closing for the night  
so that it can pull down to temperature  
overnight.  
3. Stock bottles upright only.  
4. Do not add warm product during selling  
hours.  
Defrost should be scheduled for a time imme-  
diately following product loading to allow for  
the fast pull down.  
5. If possible, load just before or during defrost.  
The LED display shows the calculated actual

OPERATING TIPS  
• Unplug the unit before cleaning. Clean the  
unit frequently to minimize odors and to main-  
tain operating efficiency.  
• 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.  
• Do not add warm product.  
• Restocked product may freeze.  
• Never place product on the bottom of unit.  
• 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.  
• Place the lower removable shelf flush against  
the back to maintain proper air flow and  
product temperature.  
• 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 remain upright at all times.  
Do not tilt more than 30 degrees from vertical  
at any time.  
• 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.  
• The light switch is located on the top right  
side of the interior back wall.  
• Maintain air flow around the unit at all times.  
• 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.  
To obtain warranty information  
or other support, contact your  
Hussmann representative  
1-800-504-4828.  
• 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.  
Please include the model and  
serial number of the product.  
Or go to  
serv/warranty.htm  
• 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.

HUSSMANN CORPORATION  
Limited Warranty for Chill Chambers in the United States & Canada  
This warranty is made to the original user at the original installation site and is not transferable.  
BASIC WARRANTY  
Hussmann Chill Chambers are warranted to be free from defect in material and workmanship under normal use and  
service for twelve months. Unless otherwise indicated, this warranty is valid from the date of original installation,  
not to exceed fifteen months from the date of shipment from the factory.  
Except as otherwise specifically set forth, Hussmanns obligation under this warranty shall be limited to repairing  
or exchanging any part or parts, without charge, FCA factory or nearest authorized parts depot (Incoterms 2000)  
during the warranty period, which is proven to the satisfaction of the warranty administration organization to be  
defective. Hussmann, or its designee, reserves the right to inspect the jobsite, installation and reason for failure.  
Hussmann will also pay the cost of labor to install and/or replace parts at prevailing straight-time rates and repair  
times which are in accordance with industry standard repair times as administered by the warranty administration  
organization.  
Hussmanns warranty covers the Chill Chamber and all its components except lamps, driers, fuses and other  
maintenance type replacement parts for the applicable warranty period. Additionally, for thirty-six months from  
date of installation, Hussmann warrants all sealed, multi-glass assemblies. If within the warranty period, it can be  
proven to the satisfaction of Hussmanns warranty administration organization that there is impaired visibility  
through a multi-glass assembly caused by moisture between the glasses, the multi-glass assembly will be replaced  
free of charge, excluding freight charges from the factory or nearest authorized parts depot. This warranty excludes  
accident, misuse, or glass breakage.  
For Chill Chamber motor compressors, excluding capacitors and relays, Hussmann agrees to repair or exchange, at  
its option, the original compressor unit only, with a compressor of like or of similar design and capacity, if it is  
shown to the satisfaction of Hussmann that the compressor is inoperative due to defects in factory workmanship or  
material under normal use and service as outlined in Hussmanns“Owners Manual”which is shipped inside new  
Chill Chambers. Hussmanns sole obligation under this paragraph shall be limited to five years from date of factory  
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  
Any warranty may be extended for an additional period (not to exceed a total 60 months in combination with the  
basic warranty), but must be purchased from Hussmann and documented with a paid invoice to be valid. The  
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.
