ATOMIC AQUATICS FIRST AND SECOND STAGE REGULATORS MAINTENANCE PROCEDURES • 9/2003 10
3. Removal of Inflator Stem.
Unscrew the inflator cover using the Atomic 2nd Stage AFC removal tool. Using the short flat bladed screwdriver,
unscrew the plastic seat retainer from the plastic body. Now depress the inflator button and unscrew the inflator
stem from the button. Put the button and spring aside. Push the stem and rubber seal out of the plastic body. Using
an o-ring pick, remove the plastic bushing and o-ring from the body.
4. Removal of Exhaust Valve
Unscrew the plastic exhaust cover. Lift up the edges of the exhaust valve and unscrew the plastic exhaust valve
spider. If it is too tight, use the open jaws of a pair of long nosed pliers placed in between the legs of the spider
to unscrew it. Remove the thin rubber gasket.
5. Removal of Deflation Button
Using the 7/16" nut driver, unscrew the nut holding the exhaust seal from the exhaust stem. The button, stem,
spring, washer and o-ring are now free from the case. Leave the stem attached to the button. If the unscrewing
the nut happens to unscrew the stem from the button instead, the result will be the same.
6. Removal of Valve Body from Case
Pull back and remove the hard rubber dust protector from the nipple of the inlet. Using an o-ring pick, push the
C-clip out of its groove and slide it off the nipple. Don’t spread it open or you will bend it. Push the valve body
assembly out of the plastic body.
7. Disassembly of Valve Body
Using a 1/2" open end wrench on the inlet and adjustable wrench on the valve housing, unscrew the inlet from the
housing. Be careful not to slip the wrench and damage the wrench flats on the inlet. Remove the orifice and plastic
orifice sleeve from the housing.
8. Disassembly of Valve Housing
Place the open end of the housing on a flat surface. Hold it in place to keep the parts inside from flying out during
the next step. Using the 1/4" nut driver, unscrew the locknut completely from the poppet. The poppet and spring
will drop free of the housing. Save the washer and small plastic insert in the top pf the housing. The locknut is
usually replaced with a new one in the service kit.
Part 3. SS1 Assembly
9. Assembly of Inflator Stem.
Replace and generously lubricate the o-ring in the plastic case. Follow it with the bushing and the rubber seal.
Make sure the bushing and seal are seated properly into the case. Thread the seal retainer into the body until it
touches the seal to keep it in place but don’t tighten it yet. Insert the stem through the retainer and push it through
the assembly until the threads come through the top of the case. Place the spring under the inflator button and screw
the stem into the button until it is snug. Now tighten the seal retainer until it is snug. Operate the button several
times to make sure it works smoothly.
10.Assembly of Deflation Button
Replace and generously lubricate the o-ring in the plastic case. Coat the top of the o-ring with lubricant and place
the washer on top of it. Coat the stem with lubricant and place the spring onto the shaft (large end toward button).
Install the shaft through the washer, o-ring and plastic case. Install the exhaust seal onto the shaft (small diameter
first) and secure with the nut. Operate the button several times to insure it works smoothly.
11.Assembly of the Exhaust Valve.
If you have replaced the exhaust valve with a new one, cut off the rubber tip near the base of the valve. Replace
the gasket onto the exhaust valve spider. Hold the spider upright to keep the gasket in place and screw the spider
with the exhaust valve into the case. Snug it hand tight. Make sure the spider is completely screwed in. Operate the
deflation button to insure the exhaust seal seats on the spider when the button is fully depressed. Replace the
exhaust cover and snug it hand tight.
