Gardner Denver AirSmart VS80-110B Operating And Service Manual page 25

STARTING THE UNIT - Observe the following starting procedures.
Unit Cold - If the unit is fitted with water cooled heat exchangers, fully open water inlet valve(s). If the
unit is located in a cold environment (e.g., ambient temperature below 40F, (5C), the required external
heat source must be energized prior to start. Press the red "STOP/RESET" button to clear any conditions
(e.g., "Loss of Power" when electrical system was energized) and start the unit by pushing the green
"START" button. Since the unit is equipped with a minimum pressure valve (80 psig, 5.5 bar), no special
procedure to maintain minimum reservoir pressure is required.
Unit Hot - Start-up instructions are the same as that of a cold start.
DAILY CHECK - Refer to Section 14; page 76 "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.
