Unit Description
27
CYCLE-SENTRY Start-Stop Controls
The CYCLE-SENTRY Start-Stop fuel saving system provides
optimum operating economy.
CYCLE-SENTRY automatically starts the unit on
microprocessor demand, and shuts down the unit when all
demands are satisfied.
The system automatically monitors and maintains
compartment temperatures, the engine block temperature and
battery charge levels at a point where quick, easy starts are
possible.
Defrost
Frost gradually builds-up on evaporator coils as a result of
normal operation. The unit uses hot refrigerant to defrost the
evaporator coils. Hot refrigerant gas passes through the
evaporator coil and melts the frost. The water flows through
collection drain tubes onto the ground. The methods of defrost
initiation are Manual and Automatic.
Automatic Defrost:
The controller is programmed to
automatically initiate timed or demand defrost cycles. Defrost
intervals are set at the factory at 2, 4 6, 8, 10, or 12 hours. The
unit can enter a demand defrost cycle as often as every 30
minutes if required.
Manual Defrost:
The operator manually initiates a defrost
cycle.
NOTE: The unit will not perform a Manual Defrost cycle
unless the
O
N
/O
FF
switch is set to
O
N
, the unit is running in
Continuous or CYCLE-SENTRY mode, (or shut down in
CYCLE-SENTRY Null mode), and the coil temperature is
below 45 F (7.2 C).
WARNING: Set the unit
O
N
/O
FF
switch to
O
FF
before opening doors or inspecting any part of the
unit. With the unit
O
N
/O
FF
switch in the
O
N
position,
the unit may start at any time without warning.
