Installation: 
Location: installed in the location with minimal vibration. Temperature of the medium should be -15 / +60 ℃. SA101 is produced at normal insider temperature, so its better to be mounted in a similar condition. High humidity may cause condensation phenomenon, the hoseconnecting knot should be keep downwards. Pressure connections and wiring: Pressure connection point marked P1 ⊕ and P2Θ, can not be wrong.

Note: 
+ To avoid electrical shock or damage to equipment / when remove the cover Make sure the power switch is turned off. 
+ Should check the wiring connection status before using/ incorrect connection may cause permanent damage to this device. 

Assembly instructions: 
+ As long as the mounting surface can bewith minimal or no shock vibration, the pressure switches can be fixed on the pipe, panel heaters or air conditioning unitsdirectly. 
+ To ensure the accuracy of the operation, the pressure switch should be mounted vertically
