OVERVIEW

This chapter illustrates the replaceable components for the EverFlo Oxygen Concentrator. Procedures for replacing the
components are also provided in this chapter.
•
To prevent electrical shock, disconnect the electrical supply before attempting to make any repairs to the
EverFlo Concentrator.
•
Use extreme caution when handling the Capacitor. The Capacitor can hold a substantial electrical
charge until it is properly discharged.
•
Even with the unit disconnected from the electrical supply, the Capacitor may still hold an electrical
charge strong enough to cause serious bodily injury. DO NOT touch the capacitor terminals
simultaneously until the Capacitor has been completely discharged. Discharge the Capacitor by shorting
the two posts with an insulated screwdriver.
•
Avoid handling the molecular sieve material. Respironics recommends the return of the sieve canister
assembly to Respironics for any service that involves sieve material.
•
Electronic components used in this device are subject to damage from static electricity. Repairs made to
this device must be performed only in an antistatic, ESD-protected environment.
•
During all repair and replacement procedures, ensure that any connections that are broken during the
process (fittings, tubing, and hoses) are reconnected securely.
•
When using a leak detector, be careful that it does not come in contact with any electrical components.
•
The fuse on the Main PCA must be replaced with the fuse called out in the Repair Kits Section of this
Service Manual. Failure to do so will result in damage to the unit.
