Instructions for TUC-60-32F, 67F,
93F, TWT-60-32F,
67F, and 93F models.
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.

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
