through collection drain tubes onto the ground. The methods of Defrost
initiation are Automatic and Manual.
A Au utto om ma attiicc D De effrro osstt::The SR-4 automatically initiates timed or demand
defrost cycles. The SR-4 microprocessor can be programmed to initiate
timed defrost cycles at intervals of 2, 4, 6, 8, or 12 hours. Demand defrost
cycles occur if the differences between the return air temperature, discharge
air temperature, and coil temperature exceed certain limits. The unit can
enter defrost cycles as often as every 30 minutes if required.
M Ma an nu ua all D De effrro osstt:: In Manual Defrost Mode, the operator initiates a defrost
cycle. See “Initiating a Manual Defrost Cycle”.
N No otte e:: The unit will not perform a Manual Defrost cycle unless the unit has
been turned on with the ON key, the unit is running in Continuous or
CYCLE-SENTRY mode (or shut down in CYCLE-SENTRY Null mode),

HMI control panel and place the microprocessor On/Off switch in the Off
position before inspecting or servicing any part of the unit.
When CYCLE-SENTRY Mode is selected, the unit will start and stop
automatically to maintain setpoint, keep the engine warm, and the battery
charged. When Continuous Mode is selected, the unit starts automatically
and runs continuously to maintain setpoint and provide constant airflow.
Features of the CYCLE-SENTRY system are:
• Offers either CYCLE-SENTRY or Continuous Run operation.
• Controller regulated all season temperature control.
• Maintains minimum engine temperature in low ambient conditions.
• Battery Sentry keeps batteries fully charged during unit operation.
• Variable preheat time.
• Preheat indicator buzzer.
