Close the main line hand valve, if necessary, to set the desired maximum operating
pressure. Maximum pressure should be approximately 10 psi [70 kPa] above normal
pre-wetting pressure.

If for any reason the system is unable to correct to the desired LIQ CAL rate, check
for an empty tank, a plugged line, a malfunctioning pump, improper vehicle speed
or a defect in the system.
