REPAIRS AND SERVICE 

It cannot be assumed that a regulator is in good working condition on the basis that it has 
received little use since it was last serviced. 

Remember that prolonged or improper storage can still result in internal corrosion and/or 
deterioration of O-Ring seals. 

If any component of your regulator assembly requires repair or service, return it to your 
local authorized supplier or dealer for professional service by a trained technician 
authorized to perform the OMS authorized service. 

If the regulator is used for rental or training purposes, it will require a complete overhaul and 
factory-prescribed service every three to six months. 

Chlorinated swimming pool water is an especially damaging environment for SCUBA 
equipment. High levels of chlorine and PH balancing cause certain components to rapidly 
deteriorate. 

Once each year your complete regulator assembly should be inspected and serviced by an 
authorized OMS supplier or dealer. 

More frequent service is recommended if you dive in severe conditions or more frequently 
than an average diver. 

DO NOT attempt to disassemble or service your regulator on your own. Doing so may 
cause the regulator to malfunction, and will render the supplier warranty null and void. 

All service must be performed by an authorized OMS supplier or dealer. 

If verdigris or contaminant residue is found on the surface of the filter, it is strongly 
recommended NOT to dive with the regulator until it has received factory-prescribed service 
from an authorized supplier or dealer. 

NOTE for personally-owned equipment used for recreational diving activity: 

Equipment used 100 dives or less per year should be serviced at least once per 
year. 

Equipment used more than 100 dives per year should be serviced after every 100 
dives prior to further use. 

NOTE for equipment used for dive training and/or consumer rental activity:
