Optional Captive Air (Bladder) Tank Installation
In some applications a captive air style (bladder) tank may be used instead of an atmospheric tank. When
installing a captive air style tank with a TX RO a reverse acting pressure switch and relief valve are required.
The pressure switch is set at 30/50 to turn the TX RO on at 30 psi and shut it off at 50 psi.
Important: The relief valve is used as a safety in case the pressure switch fails. The relief valve is
set at 100 psi to open up and allow pressure to relieve from the tank. The relief line is run to the
drain.

1. The #10284A Pressure Switch spring is set so that the turn on pressure is 30 psi and the turn off is 50
psi. (Note: The 30/50 setting is standard. If a different switch setting is required, the spring on the switch
must be adjusted.)
2. Connect 2 conductor cables (2 wires) to the normally open contacts on the #10284A Pressure Switch.
This is a low voltage contact so the wire conductor size can vary (normally between 14 and 20 gauge).
3. Run the 2 conductor cables into the TX RO control panel and connect to the contacts on the controller
marked LSH (Figure 6).
Note: Terminals on board
accept wire size up
to #12 AWG.
