2. With the cylinder securely installed, remove the
cylinder cap. Stand to one side away from the out-
let and open the cylinder valve very slightly for an
instant. This blows away any dust or dirt which may
have accumulated in the valve outlet.
WARNING
BE SURE TO KEEP YOUR FACE AWAY FROM THE
VALVE OUTLET WHEN "CRACKING" THE VALVE.
Never stand directly in front of or behind the flow
regulator when opening the cylinder valve. Always
stand to one side.
INSTALLATION
3. Attach the flow regulator to the cylinder valve and
tighten the union nut securely with a wrench. The
flow regulator for carbon dioxide must have a plas-
tic washer seated in the fitting that attaches to the
cylinder to prevent leakage. Refer to K1800-1 in
the accessories section.
4. Refer to Figure A.6. Attach one end of inlet gas
hose to the outlet fitting of the flow regulator and
tighten the union nut securely with a wrench.
Connect the other end to the SP-135 PLUS Gas
Solenoid Inlet Fitting (5/8-18 female threads — for
CGA — 032 fitting). Make certain the gas hose is
not kinked or twisted.
