JOHNSON CONTROLS F93H-1C, F93H-1
F93 Deep well controls open the air valve on a fall in tank water level to bleed excess air from the tank at pressures up to 100 PSI. The F93H has a minimum pressure release valve to avoid lowering tank pressure below 25 PSI. Its use is recommended on applications where water may be rapidly drawn.
Use Teflon thread sealing tape only. (Pipe dope may corrode the plastic, causing it to crack)
