Operating instructions

NOTES
• To ensure adequate protective gas flow to the protected enclosure, all piping and tubing must be
fully reamed.
• Precaution must be taken to prevent crimping and other damage to protective gas piping and
tubing. Caution must be used when opening/closing swing panel to prevent tubing kinks.
• Supplied 1/4” & 3/8” Poly Tubing have ferrule, nut & insert preset. Use that end for connecting to
power box. Cut other end to attain desired length and connect to push-in fittings on
Purge/Pressurization Unit.
• The Tamper-Proof (Primary) Regulator is intended to prevent tampering, while allowing a more
stable setpoint to be achieved in the small, tightly sealed enclosure where the protective gas flow is
critically low and difficult to stabilize. A 5/64” Hex Key or Allen Wrench is required to operate.
• When performing Initial Purge/Pressurization, adjust Primary Regulator to 5 psi. Normal operating
pressure is .25 inches of water at Dome Pressure Gauge. Balance Primary and Secondary
Regulators for continuous purge by alternately adjusting Primary (5 psi) and Secondary (.25 inches
of water).
