INSTALLATION / OPERATION INSTRUCTIONS
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 Screwdriver
1/4” Nut Driver or Socket
Locating The Defrost Timer:
Take off louvered grill assembly by
removing four (4) corner screws.
Single Door Models:
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.

In order to program the time to begin the
defrost cycle, flip the white tabs out to set
