    3. While the machine is still operating, disconnect from external power. 4. Verify that the power loss alarm LED illuminates on the front panel and audible alarm activates. The audible alarm will beep approximately once every 20 seconds. If the unit has not been used for an extended period of time, it needs to operate for several minutes to recharge the power failure alarm.

    3.0 User Instructions 3.1 Instructions It is important that patients thoroughly understand how to operate the CAIRE NewLife unit. This enables proper treatment, as prescribed by a licensed health care provider/physician. If users experience any discomfort or the unit alarms, they must notify their licensed health care provider/physician immediately.

  • Page 28: Solenoid Valves

    5.4 Solenoid Valves The NewLife uses five two-way solenoid valves: two feed, two waste, and one equalization. Each valve has an open (energized) and closed (de-energized) position. As the NewLife operates, two valves are always energized. The solenoid valves of the NewLife unit require no scheduled maintenance. If a valve becomes noisy, you can easily replace the internal valve parts.

  • Page 30: Sieve Beds

    5.5 Sieve Beds The NewLife unit utilizes two sieve beds, each containing molecular sieve. The unique property of molecular sieve enables it to physically attract nitrogen when air passes through this material, thus producing highly concentrated oxygen. While one sieve bed produces high concentration oxygen, the other is purged of the nitrogen it adsorbed (collected) while it concentrates oxygen.

  • Page 31: Cabinet Fan

    5.6 Cabinet Fan The cabinet fan pulls ambient air into the NewLife unit. As this air is drawn in, the air cools internal components (including the compressor) and exits out the bottom of the unit. The cabinet fan for NewLife is located in the back of the unit. Refer to the troubleshooting chart in Section 6.0 of this manual for instances where replacement of the fan may be required.

  • Page 32: Circuit Board

    5.7 Circuit Board The solid-state printed circuit board controls the timing operation of the five solenoid valves and the alarm system functions. Consult the troubleshooting chart in Section 6.0 to determine when to replace the printed circuit board. The Printed Circuit Boards (PCBs) contain components that are sensitive to electrostatic discharge (ESD) and can damage the board if not handled properly.
