13.Install the diaphragm 18 into the case 17 so that it sits evenly on the ledge.
14.Inspect the diaphragm retaining ring 19 . You will see a long tab and a short tab on the ring. The short tab lines up with the short notch in the case when the ring is installed.
a.If the diaphragm is blue, the retaining ring must also be blue to give the proper fit.
b.If you are replacing a white or black diaphragm with a new blue diaphragm, the black retaining rings will not fit properly. You must use a blue retaining ring! These rings are available from your Sherwood Scuba distributor at no cost. You should always have several on hand.
15.Install the proper diaphragm retaining ring into the case so that it holds the diaphragm in place.
16.Install the cover 21 onto the case by first hooking the bottom section over the exhaust valve area, and then working the rest of the up and over the front section. Work the cover around with your hands until everything is in place.
17.Using a size "0" square drive screwdriver or a Phillips screwdriver, install the cover retaining screws 20 through the screw holes in the cover and into the holes in the case. Do not overtighten! These screws are threading into plastic, which will hold well in service but is easily stripped if the screws are overtightened.
