Hussmann ARV-1230, Owner'S Manual

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 Hussmann Beer Merchandiser’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 ARV models is located
behind the front grille below the merchandiser
door. Unplug the unit, then lift the grille and
bring it forward off the rivet heads. (The ARV-
570 front grille is held with screws at the side.
The ARV-1230 front grille is held with pins.) 

When power is first applied, the Safe-NET dis-
play will show the version of software installed.
The initial scroll is as follows:

The Version will change dependent on 

current version installed.   

(

The temperature of air entering the evapo-

rator depends on surrounding ambient 
temperature and the amount of time the case
has been running.

• Open the Safe-NET controller using a small
flat blade screwdriver to pop off the oval cover
(this may be tight).

• Plug in the ARV models. 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 view EASY
menu, 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.
