CLEANING & INSPECTION PROCEDURES

1. All parts should be cleaned first in a warm (not over 120°F) mild soap

and water solution. Use a soft nylon bristle brush to help remove any

excess or loose contamination. After an initial warm water and soap

cleaning all parts should be thoroughly rinsed in clean fresh water

and dried with filtered low pressure (30 psig) air. After an initial

cleaning in warm soap and water solution, metal parts should be

cleaned in an ultrasonic cleaner using the appropriate ultrasonic clean-

ing solution (see Lubricant and Cleaner Table 2).

Be sure all O-rings and other rubber or plastic parts are re-

moved before cleaning in an ultrasonic cleaner or chemical bath.

Cleaning solutions may damage these components.

2. If an ultrasonic cleaner is not available, metal parts can be cleaned by

soaking the metal parts in a chemical bath solution of Chromesafe

(see Lubricant and Cleaner Table 2) and agitating gently for 3-4 min-

utes. Cleaning of metal parts can also be done by soaking in a mild

acetic solution (distilled white household vinegar) for 10-15 minutes.

Cleaning times in excess of those recommended may damage

plated parts. Never clean parts for longer than specified by the

manufacturer of the solution used. After completion of clean-

ing in any solution, thoroughly rinse parts with clean fresh water

and blow dry with low pressure (30 psig) air. Only brass, plated

brass, and stainless steel parts should be immersed in chemi-

cal cleaning solutions.

Use hand and eye protection when handling chemical cleaning solu-

tions.

3. After cleaning, all parts should be thoroughly rinsed in fresh water

and dried with filtered low pressure (30 psig) air.

Before performing any reassembly, it is important to inspect all

parts, both new and those that are being reused, to ensure that

each part is clean and free of any contamination, corrosion, or

blemish.

4. All O-rings should be replaced at every servicing. New O-rings should

be inspected for contamination and/or imperfections, and lightly

dressed with a thin film of approved lubricant prior to installation.

(See Lubricant and Cleaner Table 2.)

Do not use any petroleum based lubricants or products, or any aerosol

silicone sprays on any part of Sea Quest/ Apeks regulators. The petro-

leum base or propellant gas may attack or weaken plastic or rubber

parts. Refer to Table 2 for a list of approved lubricants.
