Pressure Fault Actions
The HydrX system requires a minimum15 psi reading on its pressure sensor for system startup with new filters. If pressure is
lower than 15 psi the following steps can be taken.
1. Enter the FCC Self Diag. screen (see Figure 11) by following the steps in “Accessing FCC Manual Control” above.
2. At the D_OUT buttons on the IN OUT screen (see Figure 13), touch 0 and 2. If the pressure is still below 15 psi, de-
energize the devices and verify general troubleshooting steps have been followed before continuing.

3. If adequate pressure cannot be generated, the STP Adapter ball valve and check valve must be inspected:
Tag, lockout power to the STP.
- Remove and inspect the STP Adapter ball and check valve for any debris that may be restricting flow.
- Verify that the ball valve is opening fully.
- Re-install STP Adapter assembly and repeat Step 2 to check pressure.
