Cleaning the Sensors in the manifold over time is required, the pressure sensors inside the manifold may become contaminated with dirt, oil, and other contaminants in normal operational use. To do so, please follow the guide below: ......................................................................................................................................................................................................................................................................................................................................................
1. Never use an object such as a cotton swab to clean the sensor, you may cause damage to the sensor. ......................................................................................................................................................................................................................................................................................................................................................
2. Open all valves and cap all the ports except for the VAC port on the SM480, or the central port on the SM380. ......................................................................................................................................................................................................................................................................................................................................................
3. Drop enough Isopropyl (rubbing) alcohol into the VAC/middle port using an eye dropper or funnel so that it can flush out contaminants. ......................................................................................................................................................................................................................................................................................................................................................
4. Cap VAC/middle port and gently shake your Manifold upside down to clean sensor.
......................................................................................................................................................................................................................................................................................................................................................
5. Turn right side up. Open a port to pour out the rubbing alcohol and open all ports to allow sensors to dry out. Drying usually takes about an hour. Repeat if necessary if issues persist.
