INSTALLATION / OPERATION INSTRUCTIONS
DEFROST TIME CLOCK OPERATION
(GRASSLIN TIMER)
RECOMMENDED DEFROST SETTINGS:
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.
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 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.
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 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.
