4 .0 SPECIAL FEA TURE S OF THE MAXIMUS SRB3600 REGUL A TOR 4 .1 FIRS T ST AGE FEA TURE S 1 The external adjustability of the first stage allows you to adjust the regulator output to match the type of diving being done. Relatively low outlet pressure (120 psi, 8.
BEFORE Y OU BEGIN: Before you begin disassembly of the regulator , test the first and second stages for output pressures and leakage. Pretesting in this way will help you to pinpoint any specific areas requiring repair . Make sure your work area is clean and well lighted, with clean compressed air available to blow sand and dirt from parts.
5. 2 DISASSEMBL Y Of FIRS T S T AGE T o view all the parts used in the first stage, fold out the front cover of this manual. The circled numbers below refer to the corresponding numbers on the drawing. 1. Use 6" or 8" adjustable wrenches to disconnect all hoses from the first stage.
8. Use a regulator support handle and a 15" adjustable wrench or bench vise to remove the cap and pressure adjusting ring as a unit from the main body . Keep the wrench on the adjusting ring flats, not on the cap flats, for this operation. This will ensure that the two units do not separate (see Photo # 3).
b. Use a clean, dry cloth to wipe the piston surface if it needs cleaning. c. Do not put the piston in a cleaning solution or ultrasonic cleaner . If there is any oil on the surface, it will coat the piston. d. A coating of grease or oil will interfere with the air flow through the flow control element in the face of the piston (see Photo #5).
16. Remove the one-way bleed valve from the body using your fingers or a soft plastic probe. DO NOT use a metal screwdriver or blade since this will scratch the sealing surface against which the bleed valve seals. This scratch may allow water to enter the first stage spring chamber during use.
nicks, scratches, or corrosion at the top of the cone can allow air to pass, which could result in creeping hose pressures. Polish out the defects using a fine abrasive polishing stick. When polishing, apply a light pressure to prevent excessive wear on the cone.
11 9 a greased soft probe, lightly lubricate the first 1/8" of the small bore in the main body where the small piston O-ring will seal. 1 1. Install the pressure adjusting ring/cap assembly onto the body . Hand-tighten the assembly onto the body until it bottoms on the thread.
12 bubbles. The air entering the cylinder will gradually empty some of the water out of the cylinder . b. After exactly one minute, remove the graduated cylinder from the air flow and raise the cylinder to the surface so that the air/water dividing line inside the cylinder matches the water level outside the cylinder .
13 6.0 SECOND S T AGE PROCEDURE S 6.1 T OOLS REQUIRED FOR SECOND S T AGE SERVING - 5/32" nut driver (if you don't have a 5/32" nut driver , use a 5/16 - 18 x 2" socket set screw) -.
b. If the tab has a metal grip ring holding the logo into the cover , grasp the ring with pliers so that squeezing the pliers causes the jaws of the grip ring to open. Pull the grip ring off, and then remove the logo by pulling it from the outside of the case.
16. If you need to replace certain parts of the lever assembly (stem, spring, lever , etc.), you can do this by temporarily screwing the orifice housing with the orifice back onto the lever support and assembly (without the plastic case).
5. Screw the orifice housing onto the threads of the lever assembly . Use a 3/4" wrench on the orifice housing to tighten them together snugly (70 in. lbs, 7.8 nm). 6. Lubricate and install new O-rings from the annual service kit onto the orifice housing .
18. Install the mouthpiece and the new mouthpiece tie from the service kit. 6.4 SE T -UP OF SECOND S TAGE For the following adjustments, remove the exhaust tee, cover , and diaphragm. 1 T urn the adjusting knob out counter-clockwise all the way , and then in clockwise 1/8 turn.
d. Replace the diaphragm. Continue to test the gap between the lever and the diaphragm after each bending until the lever is in the correct position. 10. Return to Section 6.3, Step 13 of this manual (Assembly of Second Stage) to complete assembly of the regulator .
6.5.4 External Air Leaks 1 Attach the regulator first stage to a tank short enough to totally submerge the first and second stage in your filling station cooling water . 2. With the tank valve still turned off, flood the second stage completely with water , and then position it mouthpiece up.
7 .0 HELPFUL HINTS 7 .1 TROUBLE SHOO TING REGUL A TORS POSSIBLE CAUSE RECOMMENDED ACTION HIGH INST ALLA TION EFFORT A T DEPTH: a. Inlet filter clogged. Replace the filter . b. No air flowing through the dry air bleed Check the flow rate coming out of the system.
b. Diaphragm improperly installed. Visually check position of diaphragm. c. Hole in the mouthpiece at tie area. Replace the mouthpiece. d. Hole in the diaphragm. Replace the diaphragm. e. Damaged exhaust valve, or edges of the Replace exhaust valve. exhaust valve not firmly seated on the case.
cleaner , isolate the orifice from the side walls and all other parts. Do this by placing the orifice individually in a plastic cup in the cleaning hopper . This will help prevent mechanical damage to the sealing surfaces of the orifice. Polish the orifice with a clean pencil eraser .
4. Never lift the tank/BCD assembly by the regulator or hoses. 5. Surface-test the regulator by breathing lightly through the mouthpiece. Depressing the purge button above the water's surface is not a thorough method for fully testing the function of the regulator .
