DBC 3" Series Dry Disconnects

31. While holding the coupler BODY firmly, push the LEVER towards

the open position and allow the coupler to open itself using the spring

force against the SEAL CYLINDER. The coupler should 'snap' to the

open without delay and the SEAL CYLINDER movement should

remain in contact with the POPPET movement. If the SEAL

CYLINDER separates from the POPPET or if the movement is

'sluggish', do not return this unit to service.

Test Procedure

The procedure for testing these products involves applying pressure

to the coupler, submerging the coupler under water and checking for

the appearance of bubbles. Generally the appearance of bubbles

indicates a leak and is cause for rejection. There is often trapped air

in various parts of the unit so the tester needs to make sure that the

bubbles being seen are a leak (a steady repeating bubbling pattern)

and not merely trapped air being released.

Safety glasses must always be worn when using

compressed air for any testing.

Never rotate the LEVER to the open position while the

coupler is under pressure and not coupled to a Dry Disconnect

Adapter. This action can cause the LEVER to rapidly rotate and

cause injury.

1. Install a test plug with airline adapter into the threaded end of the

coupler.

2. With LEVER in closed position, pressurize the coupler to between

3 P.S.I.G. and 5 P.S.I.G. Submerge under water and check for leaks.

(Low Pressure Closed)

3. Remove pressure and rotate LEVER to the open position.

4. Pressurize the coupler to between 3 P.S.I.G. and 5 P.S.I.G.

Submerge under water and check for leaks. (Low Pressure Open).

5. Increase pressure to 30 P.S.I.G. while still under water and check

for leaks. (High Pressure Open).

6. Remove pressure, remove unit from water and close LEVER.

7. Pressurize the unit to 30 P.S.I.G. Submerge under water and

check for leaks. (High Pressure Closed)
