DEFROST TIME CLOCK OPERATION
Instructions for TAC-48, TAC-48GS, and TAC-72RC 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
TAC Defrost Timer Location: Defrost timer is located in a ballast box behind the front louvered grill on the left side of the unit. Four corner screws on the front louvered grill will need to be removed. The ballast box has two 1/4” hex head screws that need to be removed to gain access to the defrost control.
Setting the timer:(UNPLUG UNIT FROM
POWER SUPPLY!)
(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.
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.
