sounds when the setpoint is changed until the Enter
Key is pressed. It also sounds when a Mode Key selec-

8. OVERLOAD RELAY—Manual Reset (Model 50). An
overload relay protects the standby electric motor. The
overload relay opens the circuit to the electric motor if
the motor overloads for any reason (e.g., low line volt-
age or improper power supply) while the unit is on
electric standby operation.
UNIT OPERATION
Manual Pretrip Inspection (Before Starting
Unit)
The following Manual Pretrip Inspection should be com-
pleted before starting the unit and loading the trailer. While
the Manual Pretrip Inspection is not a substitute for regu-
larly scheduled maintenance inspections, it is an important
part of the preventive maintenance program designed to
head off operating problems and breakdowns before they
happen.
1. FUEL. The diesel fuel supply must be adequate to
guarantee engine operation to the next check point.
2. ENGINE OIL. The engine oil level should be at the
FULL mark with the dipstick turned (threaded) into oil
pan. Never overfill.
3. COOLANT. The engine coolant must have antifreeze
protection to -30 F (-34 C). Code 37 indicates low cool-
ant. Add coolant in the expansion tank.
CAUTION: Do not remove expansion tank cap
while coolant is hot.
4. BATTERY. The terminals must be clean and tight.
5. BELTS. The belts must be in good condition and
adjusted to the proper tensions.
6. ELECTRICAL. The electrical connections should be
securely fastened. The wires and terminals should be
free of corrosion, cracks or moisture.
7. STRUCTURAL. Visually inspect the unit for leaks,
loose or broken parts and other damage. The condenser
and evaporator coils should be clean and free of debris.
Check the defrost drain hoses and fittings to make sure
they are open. Make sure all the doors are latched
securely.
