INSTALLATION

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.

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.

3. Attach the flow regulator to the cylinder valve and

tighten the union nut securely with a wrench..

NOTE: If connecting to 100% CO

certain the plastic washer is seated in the fitting

that attaches to the CO

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-170T Gas

Solenoid Inlet Fitting (5/8-18 female threads — for

CGA — 032 fitting). Make certain the gas hose is

not kinked or twisted.

5. Reinstall case side before connecting input power.
