Install ground and wire BEST CONTROL according to local code and National Electrical Code 
requirements. 

Depressurize the system and disconnect power supply before installing or servicing BEST CONTROL. 

Make sure line voltage and frequency of power supply match motor nameplate voltage and frequency 
and BEST CONTROL voltage and frequency. 

Install BEST CONTROL according to all plumbing, pump and well code requirements. 

Pipe joint compound can cause cracking in plastic. Use only Teflon tape when sealing joints in plastic pipe or
