A. Install the Type Z Purge Gauge Assembly to the rear of the bath as shown. The
bracket attaches to the rear of the bath and is held in place by a 6-32 x 1/4” screw
on the shoulder spacer and by a 1/4” bulkhead hex nut on the gas inlet fitting.
B. Connect the small white silicone tube attached to the gauge to the gas inlet fitting
using the compression nut provided.
C. Attach the filter with 5 foot tube to the plastic elbow fitting located at the base of
the bath. Insert the filter into the fitting and tighten the nut. Connect the tube to
a clean gas source.
D. Test the system by turning on the gas flow to the Z Purge System. Adjust the
gas flow until the gauge reads 0.1 inches water pressure.
WARNING - If this unit is located in a hazardous area where volatile fumes are present,
the Z-Purge System must be activated for a minimum of 10 minutes prior
to activation of bath power. Please review the Safety and Operations
