OPERATING THE SALVAGE AIR SYSTEM
 
A. CIRCULATING AIR IN THE FORWARD TORPEDO ROOM
FROM AN OUTSIDE SOURCE
 
(Figure 11-1)
 
11A1. Steps in operation.

1. Remove the cap from the high salvage hose connection to forward torpedo room, and connect the diver's hose from the salvage ship.

2. Remove the cap from the low salvage hose connection to forward torpedo room, and connect the diver's hose from the salvage ship.

3. Open the low external salvage valve to the forward torpedo room from the outside, using the diver's wrench.

4. Open the high external salvage valve to the forward torpedo room from the outside, using a diver's wrench.

The valves in Steps 3 and 4 can be operated from the deck or from within the compartment. To open the compartment salvage

  valve from the outside, turn the wrench counterclockwise. To open the same valve from the inside, turn the handwheel clockwise.

Air can now be supplied from the salvage ship through the high salvage connection and exhausted through the low salvage connection.

5. Upon completion of circulating salvage air through the forward torpedo room, shut the high external salvage valve.

6. Shut the low external salvage valve.

7. Remove the diver's hose from the low salvage hose connection and replace the cap.

8. Remove the diver's hose from the high salvage hose connection and replace the cap.

B. SUPPLYING AIR FROM THE CONTROL ROOM SUPPLY AIR TO
THE CONTROL ROOM AND THE TWO ADJOINING COMPARTMENTS
 
(Figure 11-2)
 
11B1. Preparation.

1. It is assumed that there is air in the 225-pound service air line forward and aft.

11B2. Steps in operation.

(This operation is performed in the control room.)

1. Admit air to the control room by turning clockwise the handwheel of the compartment salvage air valve located on the after bulkhead of the control room.

2. Turn the handwheel to the neutral position when sufficient air has been admitted.

3. Admit air to the after battery compartment by turning counterclockwise the handwheel of the compartment salvage air valve located on the after bulkhead of the

  control room. (This is the same compartment salvage air valve used in Steps 1 and 2.)

4. Turn the handwheel to the neutral position when sufficient air has been admitted.

5. Admit air to the forward battery compartment by turning the handwheel of the compartment salvage air valve on the forward bulkhead of the control room counterclockwise.

6. Turn the handwheel to the neutral position when sufficient air has been admitted.

7. Admit air to the control room again by turning the handwheel of the compartment salvage air valve on the forward bulkhead clockwise. (This is the same compartment salvage air valve used in Steps 5 and 6.)

8. Turn the handwheel to the neutral position when sufficient air has been admitted.

C. SUPPLYING AIR FROM AN OUTSIDE SOURCE TO MBT NO. 1
 
(Figure 11-3)
 
11C1. Steps in operation.

1. Remove the cap and connect a diver's hose from the salvage ship to the MBT No. 1 external salvage hose connection.

2. Open the MBT No. 1 salvage valve from the deck with a diver's wrench. The

  MBT No. 1 is now ready to receive air from the salvage ship.

3. Shut the MBT No. 1 salvage valve when the salvage operation is completed.

4. Disconnect the diver's hose and replace the cap on the MBT No. 1 external salvage hose connection.
