701 The water (H

nect console (only for VWI or OptiMix) is less than
2.07 bar (30 psi).

Corrective action
1. During test cutflow and test preflow, look at the CNC or XPR web interface to identify water inlet
pressure in the gas connect console.
Look at the H
2
O inlet pressure (P8) for code 701.
2. Make sure that the gas inlet pressures inside of the gas connect console are sufficient as specified in
Permitted inlet pressures to gas connect consoles on page 349.
3. Make sure that the water inlet pressure is at least 2.07 bar (40 psi).
4. When water is flowing and the pressure that you measured is not in the permitted range, use the
regulators to increase the pressure, if necessary.
Do not exceed the recommended pressures.
5. If the pressure stays too low, examine the gas hoses and gas inlet fittings for:
□
Damage or kinks that can restrict flow
□
Leaks that can decrease pressure
6. Replace the hoses if you find damage or kinks.
