AccuAir SwitchSpeed User manual

WARNING: Extended valve pulsing MAY reduce the life of your
valves.
Thank you for purchasing the revolutionary SwitchSpeed™ Controller by
AccuAir.
This air suspension controller manages up to 4 Air Springs as an intelligent
switchbox with user-adjustable control of valve speed. The AccuAir
SwitchSpeed™ also manages your Air Compressor(s) to keep onboard air
at an ideal pressure for your application (If Optional Electronic Tank Pressure
Sensor is connected).
To maximize functionality, the AccuAir SwitchSpeed™ allows you to select
from three distinct valve speeds:
1.) Full Speed.
2.) Medium Speed (Adjustable).
3.) Precision Speed (Adjustable).
The exact settings for each of these speeds is User Adjustable
(see page 10 in your Operation Manual).
At AccuAir, we pride ourselves on thorough customer service, quality
products, and a better driving experience through technologically
superior design.
