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.
11. Install the pressure adjusting ring/cap assembly onto the body. Hand-tighten the assembly onto
the body until it bottoms on the thread.
12. Lubricate the locking Allen screw with silicone grease, and place a small dab of grease onto
the hole in the main body where the Allen screw is inserted. Using a 3/32" Allen wrench, screw
the locking Allen screw into the main body until it lightly bottoms on the thread. Do not tighten
further.
13. Using your index finger, install the clean and dry one-way bleed valve into the body . No
particular orientation is necessary.
14. Lightly lubricate the body yoke nut threads with silicone grease and install the yoke and
the yoke nut onto the body.
15. Using the regulator support handle (p/n 4700-15) in one of the LP pressure ports of the body
and a 15" adjustable wrench, tighten the yoke nut snugly (see Photo # 1).
16. Lightly lubricate the threads of the handwheel with silicone grease and install the handwheel
and dust cap onto the yoke .
17. If the first stage has a SYA-5300 or SYA5200 DIN adapter instead of a standard yoke, see the
installation instructions given in Sherwood Technical Bulletin 104 for overhaul and installation
instructions of the DIN adapter.
5.4 TESTING Of FIRST STAGE
5.4.1 Before You Begin Testing
1 Install an intermediate pressure test gauge (p/n TL119) into one of the low pressure ports of the
first stage. Plug any open outlet ports with suitable port plugs.
2. Install the first stage onto a tank valve, and introduce 2700 - 3500 psig to the inlet of the
regulator. Flow air through the regulator by pushing the purge button on the second stage
several times to get all parts properly seated.
5.4.2 Dry Air Bleed flow Test
1 . Submerge the first stage under several inches of water.
2. A small stream of bubbles should be escaping from the one-way bleed valve on the first stage and
nowhere else on the body. The number and size of the bubbles may vary from regulator to regulator,
but the volume of air should be 13 - 25 cc per minute. To check this, use the following steps:
a. Invert a small (25 cc capacity) graduated cylinder filled with water over the underwater flow of
NOTE: For safety, always test the first stage regulator with at least one second stage installed. The demand
valve in the second stage acts as a relief valve in the event of a malfunction.
NOTE: If you use the bleed valve with the Sherwood logo molded into it P/N 3106-6 you will notice a "dot"
molded near the right side of the logo. Install the bleed valve with the "dot" oriented closest to the inlet of
the regulator (towards the yoke).
