(7)
Draw 10 mL sample. Agitate or rinse water to observe for soap bubbles. If any soap bubbles are present,
repeat steps (6) and (7) until no bubbles are observed.
(8)
Blow dry components with clean air, nitrogen or helium.
(9)
Reassemble components using an approved lubricant.
(10)
Bag and seal or tape closed all components and ends of pipe or hoses with plastic until ready for
reinstallation.
b.
For cleaning pipe or tubing the following procedures should be followed:
(1)
Determine the volume of cleaning solution estimating the length of pipe or hose to be cleaned and the size of
the pipe to be cleaned. Look up the appropriate pipe/tube size and then the corresponding volume (in cubic inches) per
one foot length in table 4-3. Multiply that volume by the estimated length to be cleaned. After the total volume is
calculated, multiply the answer in cubic inches by .00433. After the total volume is calculated, multiply the answer in
cubic inches by .00433 to obtain the number of gallons to fill the system. Determine applicable flow rate from table 4-4
and multiply flow rate by thirty (30) to compute number of gallons required to pump through the system. Add volume
required to fill system and the volume required to pump through the system for the total volume of cleaning solution
required.

(2)
Prepare a solution at a ratio of 2 pounds (0.9 kg) of TSP, 0.5 ounces (14.7 mL) non-ionic detergent for each
80 gallons (302.8 L) of distilled or deionized water as determined.
(3)
Heat solution to 165 degrees F (74 degrees C) mixing occasionally during the heating.
