UNLOCKING THE KEYPAD
-
Normally, the keypad is locked to prevent inadvertent
changes to settings. The Unlock Key is a white dot on the
right side of the display, centered between the other 4 keys.
Press the Unlock key twice within a second in order to unlock
the keypad (think "tap-tap"). The Keypad Unlocked LED
will turn on to indicate the keypad is now live. The keypad
will stay unlocked until there is 3 minutes of inactivity, at
which time it will automatically lock the keypad. There are
2 operations the user can perform without having to enter
a password:
• Change the cabinet temperature setpoint
• Change the rail temperature setpoint
• Initiate a defrost operation
VI. c. - ADJUSTING THE CABINET
TEMPERATURE SETPOINT
The setpoint to the unit can be changed simply by pressing
the Plus or Minus Key. There will be a slight delay at first
to prevent an accidental change, so it will be necessary to
hold the key for 3-4 seconds until the value starts to flash.
The flashing value indicates the setting is being modified.
To raise the setpoint, press the Plus Key to increment to the
setpoint you want. Similarly, press the Minus Key to lower
the setpoint. When the desired value is reached, press the
Enter/Display Key to lock in the value. Pressing the Esc Key
will abort the process and keep the original setpoint. The
keypad must be unlocked in order to change the setpoint
using the shortcut method.

VI. e. - INITIATING A DEFROST
Defrost is a necessary operation to remove frost that builds
up on the evaporator coil and reduces air flow within the
cabinet. The unit is setup to do this automatically but has
the capability to manually defrost as well.
To manually defrost the unit, press the Minus Key and the Esc
Key simultaneously and hold for 5 seconds. Units equipped
with an LED temperature display will indicate when a defrost
cycle is in process. The Defrost Symbol will illuminate letting
you know defrost is in effect. Depending on the settings, the
unit may also show "DEF".
VII. GENERAL CARE
VII. a. - GENERAL CARE
before cleaning any parts of the unit. All Traulsen gylcol
equip- ment should be cleaned only with warm water, mild
soap and a soft cloth. Apply with a dampened cloth and wipe
in the direction of the metal grain.
Avoid the use of strong detergents and gritty, abrasive
cleaners as they may tend to mar and scratch the surface.
Do not use cleansers containing chlorine, this may pro- mote
metal corrosion.
Care should also be taken to avoid splashing the unit with
water, containing chlorinated cleansers, when mopping the
floor around the unit.
For stubborn odor spills, use baking soda and water (mixed
to a 1 TBSP baking soda to 1 pint water ratio).
VII. b. - ADJUSTING THE SHELVES
Shelves and shelf clips are shipped with the unit. For each
shelf, insert four (4) shelf clips into the pilaster slots at the
same height. The shelf clips have a small projection on top
which holds the shelf in position and prevents it from slipping
forward. After installing shelf clips on pilasters, place shelves
on clips.
