SHOULD BE DISCONNECTED
BEFORE REMOVING THE
ENCLOSURE COVER.
♦ The defrost pins should be
checked for tightness. The
timer will require re-adjusting
after a power failure or the
cabinet supply is turned off for
extended periods of time. If an
additional defrost is required
due to ambient or cabinet usage
conditions, do not put a
defrost during the middle of
the day. Put any additional
defrosts during the night or at a
time when the cabinet has the
lowest usage.
DEFROST TIME CLOCK
♦ The timer is factory pre-set for
one (1) defrost cycle per 48
hours on the LBN-4 through –8
and for one (1) defrost cycle per
24 hours on the LBN-10 at
12:00 a.m. with a 40 minute
failsafe.
♦ The timer must be adjusted to
the proper time of day when the
cabinet is started. The timer is
adjusted by turning the knurled
adjustment knob in the center
of the dial face counter-
clockwise until the time
indicator corresponds with the
correct time of day.
♦ Defrost is time initiated and
temperature terminated.
♦ If the thermostat should fail,
the timer is equipped with a
failsafe set at 40 minutes that
will allow defrost to terminate
on time.
DEFROST THERMOSTAT
♦ The defrost thermostat is
located on its mounting plate
which is located on the right
hand end of the evaporator coil
attached to the air scoop which
is a right angle piece of metal
running in front of the
evaporator behind the nose
screen. The thermostat is a bi-
metal thermostat that is tied in
series with the defrost time
clock solenoid to end defrost
when the temperature has been
satisfied which is 85
o
F.
