DEFROST TIMER
DEFROST TIME CLOCK OPERATION FOR UNITS
WITH MECHANICAL CONTROL
RECOMMENDED DEFROST SETTINGS:
TRUE Manufacturing has factory set your defrost time clock to a
recommended time and duration defrost scenario. All Deli Cabinets
will require routine defrost. Your TRUE equipment has been designed
for three defrost periods (6:00 a.m., 2:00 p.m. and 10:00 p.m.). If you
decide to deviate from these defrost time settings please follow the
procedures for adjustment below.
NOTE: Defrost timer will need to be set at current time of day
before plugging unit into power supply. The defrost times have been
set from the factory. If you want to change defrost times please read
through the defrost timer instructions.
TOOLS REQUIRED
• Phillips Head Screwdriver
• 1/4" Nut Driver or Socket
LOCATING THE DEFROST TIMER:
Take off louvered grill assembly by removing four (4) corner screws.
Defrost timer is located in the lower right corner behind the louvered
grill (inside galvanized electrical box).
SETTING THE TIMER:
UNPLUG UNIT FROM POWER SUPPLY!
DO NOT SET THE TIME BY ROTATING THE "OUTER" DIAL.
Turn the minute hand clockwise until the time of day on the outer
dial is aligned with the triangle marker on the inner dial (two o'clock
position).

ADJUSTING THE DEFROST TIMER:
Time initiated, time terminated.
Your TRUE equipment contains a defrost system that is time initiated
and time terminated. While TRUE requires a minimum three defrost
periods not to exceed 60 minutes the procedure on this page should
be followed to customize your specific needs.
NOTICE: If timer is not set for a minimum of three defrost per day
for 60 minutes each, the coil may develop excessive frost. This may
lead to system failure and product loss, which is not covered under
warranty.
The following procedure may be followed to customize your needs.
High usage, high temperature, and high humidity may require four
defrost settings per day.
WARNING
Always follow the manufacturer's recommended settings when
programming the amount and duration of the defrost cycles.
STEP 1: The white tabs located on the outmost area of the time
clock have been factory set for (6:00 a.m., 2:00 p.m., and 10:00 p.m.).
Each tab represents 15 minutes of defrost time. Notice that at each
defrost time four white tabs are set for 15 minutes each for a total
of 60 minutes of defrost.
STEP 2: In order to program the time to begin the defrost cycle,
flip the white tabs out to set the defrost time. To eliminate a defrost
time flip the white tabs back toward the center of the Defrost Timer.
STEP 3: TRUE recommends a 60 minute defrost cycle three times
per day.
