3. EAN mixtures must meet minimum ANDI purity standards for oxygen compatible air.
4. Equipment must be dedicated for EAN use and not contaminated by use with compressed air that does not meet the
ANDI oxygen compatible gas purity standard.
5. Equipment that has been contaminated must be re-cleaned before use with EAN.
6. Cleaning of parts must be done with Blue GoldTM or an ANDI approved cleaning solution.
7. During regulator servicing, only Atomic Aquatics factory supplied o-rings and spare parts may be used.
8. For lubrication, only Christo-lubeTM MCG 111 or MCG 129 must be used. Do not use silicone grease in or around
EAN equipment.
! WARNING
Failure to comply with the above guidelines could result in the increased risk of ignition
or fire that could result in personal injury or death.
GENERAL
Major service which includes disassembly, cleaning, and replacement of all seats and seals is recommended either
annually (Z1) or every 2 years or 300 dives (T1x, T1, M1, B1, B2, SS1), whichever comes first. This extended service
period is due in part to the extreme corrosion resistance of the titanium components and the unique, maintenance
saving designs.
We do require that the owner performs preventive maintenance (fresh water rinsing) as outlined in the user manual.
The owner should also bring the regulator to the dealer for an annual safety inspection to check for proper functioning
and advise the customer of any problems that might necessitate an earlier than scheduled servicing. Otherwise, repair
or service should be done according to the 2 year or 300 dive schedule.
Major service kits containing all necessary service parts (o-rings, filters and seats) are available for 1st and 2nd
stages at a nominal charge. These items are not supplied free of charge under warranty unless found to be defective
from the factory .
CLEANING
In the case of the second stage and the all titanium first stages, acids or harsh chemical cleaning agents are not
needed nor recommended. Pre-clean all parts to remove major contaminants. Ultrasonic cleaning with an approved
cleaner or hot soapy water is the preferred cleaning method. Corrosion products on brass parts can be removed by
further cleaning in a 50% white vinegar/water solution or commercial scuba parts cleaner such as DT-2001*. Do not
use muriatic or hydrochloric acid solutions as they will destroy chrome finishes and may attack certain types of
stainless steels.
SPECIAL CLEANING FOR NITROX USE
We recommend cleaning with a hot solution of Blue Gold*, preferably in an ultrasonic cleaner. Dilution ratio is 1:20
Blue Gold to clean water. The optimum cleaning temperature is 140°F (60°C). Rinse thoroughly with clean water, then
air dry. Parts should be cleaned until there is no trace of hydrocarbon residue. Reassemble parts is a clean work area,
with clean or gloved hands and minimize handling of internal components to reduce contamination. Lubricate with
Christo-Lube111 or 129 only.
Special note: Simple Green CleanerTM. Although a popular cleaner, we do not recommend the use of Simple GreenTM
for Nitrox cleaning because it will break down if heated above 130°F and may leave questionable residues.
