When the water system is energized, and the cavity is at a
temperature of 225°F (107°C) or higher, condensation mist
should appear from the water nozzle located above the fan,
and behind the air baffle plate (not shown) .

Water pressure check:
Minimum water feed pressure:
Fully open the pressure
regulator control knob to determine what the line pressure is .
The gauge should read at least 30 psi .
Regulator pressure:
The regulator should be set at 20 psi
when the spritzer valve is energized .
One way to determine if water is being injected is to monitor
the pressure gauge . The static pressure reading will drop 6
- 10 psi when the solenoid valve is opening, or cycling .
