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. 

 

  ___________  STEP 3   ____________

TRUE recommends a 30 minute defrost 

cycle three times per day.
