SYSTEM CLOCK:
The Fogging system has a clock located behind the rear raceway panel.
Figure 16: The system clock interrupts the fogging system during non-
display hours. The factory settings are listed below. If different, the
store’s actual times should be programmed into the clock. The factory
clock setting is set to CST. Adjust to your time zone as necessary.
The factory default settings are:
a. Clock factory set to CST
b. On: 6am – 10 pm
c. Off: 10pm – 6 am
The benefits of interrupting the fogger system are:
•
The RO filter life will be extended
•
Any ice build-up will be cleared by this interruption.
•
The life of the case will be extended by reducing the total fogging time.
It is not recommended that product remain in the case overnight. The product should be covered, removed to
cold storage and re-stocked in the morning. However, if product is kept in the case, the clock should not interrupt
the fogging system operation and must be re-programmed.
IMPORTANT!
Check with the store personal to understand if they will be removing product for night-
time storage and if so, what are their display times. If the factory default fogging times and/or the
local time differ, the clock
must
be re-programmed.

a.
Make the case electrical connections to power time clock. A circle ¾ circle with a “1” will be displayed when
AC power is applied to the case. Confirm that the timer is in “AUTO” mode. This will be indicated with a
small arrow above the “AUTO”.
b.
Adjust the time to match the current time by pressing the “Menu” button. Adjust up and down with “+” and
“-“ keys. Press the “OK” key to confirm the item and cycle to the next entry.
c.
After the day of the week is set, the next step is to set the fogging time: “prog 1”. Change the fogger start
time for the morning as per the store’s display time. Continue to enter the evening turn-off time. Once
complete press the “Menu” button to exit programming.
d.
The “OVR” button can be used to either turn off or turn on the fogger depending on its current state.
e.
To permanently run the fogging system, the time clock will need to be reprogrammed to run 23 hours and 59
minutes. You will notice all of the hash marks from 0-24 are on.
