located in the lid with water as shown in Figure 26.
i. Secure the lid to the desiccant cartridge.
j. Verify the lid seal is correct by using the empty squeeze bottle.
i. Have a pan or cup with about one inch deep water in the bottom.
ii. Hold one finger over the output fitting.
iii. Pressurize the desiccant tube using the pressure bottle as shown in Figure 27.
NOTE: The bottle just needs to be squeezed with air in it, do not put water into the squeeze bottle.
iv. Place the desiccant tube with the lid into the water. If the lid is not sealed, the
water could flow into the desiccant cartridge. Hold the tube in the water only as
long as needed to verify the test.
v. Look for bubbles escaping from the lid. A large number of bubbles indicates the
lid is not sealed. You must remove the lid and reset the washer. Lubricate the
washer with water and put the lid back.
