INSTALLATION / OPERATION INSTRUCTIONS
RECOMMENDED DEFROST
SETTINGS:
TRUE Manufacturing has factory set your
defrost time clock to a recommended
time and duration defrost scenario. All
refrigeration equipment operating below
30°F will accumulate frost on the evaporator
coil and 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.
REQUIRED TOOLS
• 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).
Two Door Models:
Defrost timer is located in the middle of the
cabinet, behind the louvered grill. Timer is
mounted to the left of the centered ballast box
(Inside of gray timer box).
Three Door Models:
Defrost timer is located on the left upright
post behind the louvered grill (Inside of gray
timer 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 or temperature
terminated)
Your TRUE freezer contains a defrost system
that is temperature terminated, however the
time clock has been designed with a time
termination back-up so that the defrost
period will not exceed thirty minutes. While
TRUE requires a minimum 3 defrost periods
not to exceed 30 minutes the procedure on
this page should be followed to customize
your specific needs.
NOTICE
If timer is not set for a minimum of 3 defrost
per day for 30 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 4 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 two white
tabs are set for 15 minutes each for a total of
30 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.
