Unit Hot
- Start-up instructions are the same as that of a cold start.
Compressed Air Dryer (Optional) – The dryer module is fed electrical power from a separate (off-
package), disconnect provided by the end user – it must be engaged prior to dryer operation. Relay
contacts, operated by the package AirSmart controller, engage and disengage the dryer from the external
power source. The dryer is turned on when the “START” button is pressed, which also starts the
compressor system. The dryer remains powered until the “STOP” button is pressed and remains in
operation during low air demand periods that temporarily shut down the compressor. Please refer to the
dryer manual 13-18-602 for all installation, operation and maintenance instructions.
DAILY CHECK
- Refer to Section 14, “Maintenance Schedule”.
STOPPING THE UNIT
- Press “STOP-RESET” button. The oil reservoir will automatically blow down, as
the main motor is de-energized. If the unit is a water-cooled heat exchanger type, close any manual
water inlet valves after unit has stopped. Be sure external heat is turned on if below 40
°
F (5
°
C),
Automatic restarting or electrical shock can cause injury or death. Disconnect,
lockout and tagout the unit from the power supply and any other circuits before
servicing unit.
When the pressure relief valve opens, a stream of high velocity air is released,
resulting in a high noise level and possible discharge of accumulated dirt or
other debris. Always wear eye and ear protection and stand clear of the
discharge port when testing the pressure relief valve to prevent injury.
Never paint, lubricate or alter a pressure relief valve. Do not plug vent or
restrict discharge.
