dures for adjustment below.

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 mini-
mum 3 defrost periods not to exceed 60
minutes the procedure on this page
should be followed to customize your
specific needs.
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
The following procedure may be fol-
lowed to customize your needs.
High usage, high temperature, and
high humidity may require 4 defrost
settings per day.
Always follow the manufacturer's
recommended settings when
programming the amount and duration
