corrosion. Corrosion or minor scratches can be polished out using a fine-grit rubberized polishing stick or a clean new pencil eraser. Do not apply heavy pressure when rotating the polishing stick. Stop polishing immediately after the corrosion or scratch disappears. An orifice will not be accepted for warranty replacement simply because it is dirty or corroded. The technician must clean the orifice sealing surface at every service interval.

19.Blow all dust and debris out of the orifice housing with clean compressed air.

NOTE: Prior to this point, you should have cleaned and inspected all parts, following proper servicing procedures. Do not continue until this has been done.

1.Re-install the cleaned and lubricated O-ring 23 onto the adjustable orifice 22 . Install the adjustable orifice back into the orifice housing. Push it in with your finger as far as it will go.

2.Install the exhaust valve 14 into the case by inserting the nipple into the small hole from the outside of the case. Reach inside the case and pull the nipple firmly with the fingers until you hear or feel it “click” into place. Inspect the exhaust valve to see that it is properly seated.

3.Install the lever support assembly 7 into the proper hole in the case 19 from the inside. Note that the Blizzard and Oasis style lever assambly will be installed with the heat transfer fins

8 9 still attached. The fins must be installed into the mouthpiece on the correct side of the locating tabs in the top and bottom of the mouthpiece tube. When looking through the case mouthpiece tube from the outside (mouthpiece end) the fins must be on the right side of the locating tabs. Screw the orifice housing 20 onto the threads of the lever support 7 . Use a 6" or 8" adjustable wrench to tighten the orifice housing onto the lever support assembly snugly

70 in. lbs. (8 joules).

NOTE: Do not allow lubrication (grease on fingers, silicone overspray, etc.) to get on the case 19 , the diaphragm 4 , the retaining ring 3 , or the exhaust valve 14 . This may cause these parts to slip or deteriorate.

THE FOLLOWING STEPS (4 - 10) ARE INCLUDED HERE FOR CONTINUITY. THEY MUST BE PERFORMED AFTER THE REGULATOR SECOND STAGE IS ADJUSTED (see Section 5.4, Set-Up of Second Stage).

4.Install the diaphragm 4 into the case so that it sits evenly on the ledge.

5.Install the retaining ring 3 into the diaphragm recess.

6.Install the cover 2 onto the case by sliding the retaining loop over the orifice housing, and then working the cover over the case until it sits properly in its groove in the cover.

7.Install the exhaust tee 15 onto the case using the two screws 16 .

NOTE: Depending on the owner’s needs, either the Blizzard & Oasis style extended tee for maximum bubble dispersion, or the Magnum/Brut style shorter tee for minimum weight and drag, can be installed on any of the three models.
