INSTALLATION / OPERATION INSTRUCTIONS

DEFROST TIME CLOCK OPERATION (GRASSLIN TIMER)

RECOMMENDED DEFROST SETTINGS:

Adjusting The Defrost Timer: STEP 1

True Manufacturing has factory set your defrost time clock to a recommended time and duration defrost scenario. All units will require routine defrosts. 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.

REQUIRED TOOLS:

•Phillips Screwdriver

•1/4" Nut Driver or Socket

Locating The Defrost Timer:

Defrost timer is located in the lower right corner behind the louvered grill (inside galvanized electrical box).

Take off louvered grill assembly by removing four (4) corner screws.

(time initiated, time or temperature terminated)

Your True equipment 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 60 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 60 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.

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 four white tabs are set

for 15 minutes each for a total of 60 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 60 minute defrost cycle three times per day.

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).

WARNING:

Always follow the manufacturer’s

recommended settings when

programming the amount and duration of

the defrost cycles.
