Installation Instructions for the ILAS-III Valve
General Information
The ILAS-III Valve is used for the lowering and lifting of one or multiple axles on an air ride
suspension depending on the load applied to the vehicle.
Assembly
• Use the provided holes to install the ILAS-III Valve. Make sure the valve is
mounted in a location that is protected from water on the road and high
pressure cleaning. The fittings on the valve must point downward. Refer to
Figure 1 and Figure 3.
Note: If a high pressure washer is used to clean the vehicle, a distance of at least
50cm (20") should be used.
• The control button (manual version) should be easily accessible and not
protrude over the edge of the vehicle when pulled out.
• The valve should also be protected from unintentional activation.
• If the valve will be painted or coated, avoid painting the exhaust vent hole and
rubber boot for the control button (manual version).
• Check and record the lowering pressure on the valve or in an area visible
from the lift axle(s).
