Service & Repair Manual

About This Manual

Introduction

As a service technician, you are entrusted with maintaining your customer’s equipment to the same standards with which it was manufactured. At Genesis, we are committed to providing you with the tools you will need to accomplish this important task, including the information provided in this manual.

Possession of this manual, however, does not constitute an offer by Genesis

Scuba to sell component parts, nor does it qualify you to perform service or repair for Genesis Scuba products. In order to purchase spare parts or perform service and repair, you must be directly employed by an Authorized Genesis Dealer. It is

also your responsibility to obtain factory authorized training through your Genesis Scuba distributor. If you are ever unsure about how to perform any of the procedures outlined in this manual,

please contact Genesis Scuba for technical assistance.

Scheduled Service

Regulators should be given the same care and maintenance as life support equipment. It is

therefore important to perform scheduled overhaul service for the entire regulator (first and second stages) at least once every year with normal or infrequent use.

A unit that receives heavy or frequent use, however, should be serviced at least twice each year - or more often - depending on the conditions of use and the manner in which it is maintained. (Refer to the maintenance procedures outlined in the Genesis Regulator Owner’s Manual.).

When performing service, whether it is a routine overhaul or a repair of a specific problem, it is important to understand how the regulator is designed and how it operates. An illustrated explanation of the Atlas/Yukon second stage design is provided on the following page.

EAN/ Nitrox Service

Genesis regulators can be upgraded for use with oxygen enriched air (EAN/ Nitrox) not to exceed 40% oxygen content. This upgrade must be performed in conjunction with a complete overhaul, and includes a special cleaning procedure that is outlined in this manual.

Use of Warnings, Cautions, & Notes

WARNING indicates a procedure or situation that may result in serious injury or death if instructions are not followed correctly.

CAUTION indicates any situation or technique that will result in potential damage to the product, or render the product unsafe if instructions are not followed correctly.
