Instructions for TUC-60-32F,

RECOMMENDED DEFROST
SETTINGS:
True Manufacturing has factory set your
defrost time clock to a recommended time
and duration defrost scenario. 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.
REQUIRED TOOLS:
• Phillips Screwdriver
• 1/4” Nut Driver or Socket
TUC/TWT Defrost Timer
Location:
Defrost timer can be found by removing the
rear screen.
Setting the timer:
(UNPLUG UNIT FROM
POWER SUPPLY!)
Turn the clock (outer dial) clock-wise until
the correct time of day on the outer dial is
aligned with the marker of the inner dial.
(See image 2).
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 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.

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 the defrost
time. To eliminate a defrost time
flip the white tabs back toward the
center of the Defrost Timer.
