Disassembly/Reassembly Procedures: Ensuring Radio Submergibility Sec 2: 8-35
8.10.7.1 Vacuum Tool Setup
1. Attach one end of the hose to the Vacuum Pump. Attach the other side of the hose to the
Vacuum Adapter.
2. Tool Leak Test
:
i. Block the open end of the Vacuum Adapter.
ii. Pull the knob on the Vacuum Pump to create vacuum.
iii. Pump at least 15 inHg.
iv. Watch the gauge for a minute. If there is any loss of vacuum, repair or replace the tool.

remove the Memory Door (28).
2. Slide the top of the Grille Eliminator under the Control Top Bezel (10) and swing it down
towards the radio. Secure the Grille Eliminator using the two center screws (24) with a torque
of 10 in lbs. See Figure 8-53.
8.10.7.3 Test Procedure
1. Attach the Vacuum Adapter onto the radio in the same manner as a radio battery. Ensure
both latches are clicked into place.
2. Place the radio on a flat surface with the Grille Eliminator facing upward.
3. Pull the knob on the Vacuum Pump to create vacuum. The vacuum test pressure should be
between 5–7 inHg.
Ensure that the vacuum pressure NEVER exceeds 7 inHg.
The radio has pressure sensitive components that can be
damaged if the pressure exceeds this limit.
