• 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.
