Page 3: Introduction
The rated flow of an Integra E-Z 5 is five liters per minute. The rated flow of an Integra E-Z 7 is seven liters per minute and Integra E-Z 10 is ten liters/minute. Upgraded – It is the policy of SeQual Technologies to incorporate certain design improvements into machines, which have been returned to the factory for inspection and/or repair. - Page 4 There are no field serviceable components in the ATF assembly. Any attempt to open the module, without the express written consent of SeQual Technologies, will result in module contamination and will void the warranty. The ATF product flow/pressure is self-regulating by matching compressor size (pressure and volume of flow) to the rated flow of a particular ATF module.

ATF module, and POD assembly. These components are mounted to the base and center frame and are housed in a two-piece cover. Although the plastic components are common to all the Integra E-Z concentrators, refer to the appropriate model data sections concerning parts replacement. - Page 6 (a maximum of 10 minutes). The Integra E-Z oxygen concentrator does not utilize a conventional circuit breaker. A separate “current-sense” transformer mounted on the printed circuit board continuously monitors the current being drawn by the compressor.
- Page 7 Service Manual Integra E-Z Oxygen Concentrators start running. In addition the Integra E-Z has two fuses. The primary fuse F2 (service technician replaceable fuse, see Section 10 for spare parts) is used as a back-up to the current- sensing system and will prevent excessive current draw by the compressor. Another non- replaceable fuse, F1, provides protection in the event of a transformer failure.

Page 8: Set-Up And Operation
Service Manual Integra E-Z Oxygen Concentrators Set-up and Operation 2.1. The proper location. Locate the concentrator in a well-ventilated space that provides adequate airflow. Ensure that furniture, draperies or clothing will not impede air circulation. The Integra requires 6 air exchanges per hour to properly ventilate. -

2.5.2. Start-up Sequence OM units On initial start-up Integra E-Z units light the Green, Yellow and Red LED’s with a 3 second beep followed by an intermittent beep for the remainder of the warm-up. As concentration increases to ~70%, the Red LED turns off and the Yellow and Green remain on. -
Page 10: Service Mode
Use of downstream or external flow control device is not recommended. The Integra E-Z will attempt to control the flow rate to the target flow set on the indicator. If the unit cannot control to this flow rate an alarm indication will occur and potential damage may occur to the unit. -

Service Manual Integra E-Z Oxygen Concentrators 3. Maintenance Routine Maintenance: Routine maintenance consists of cleaning the air inlet filter at a weekly interval to keep the unit functioning properly. Once the filter is cleaned, dried, and re-installed. The user can easily achieve this maintenance. -

Concentrators. 4.3.2. Start-up Sequence Non-OM units Non-OM Integra E-Z units start-up with the Green, Yellow and Red LED’s lit and a 3 second beep indicating all alarms indicators are functioning followed by the green LED turning on. The table below shows the normal start-up operating conditions for Integra E-Z Concentrators. - Page 16 Off/On button to restart the Integra E-Z. 5.1.1.5.Oxygen flow rate being measure and controlled by the Integra E-Z doesn’t agree with flow set on the front panel by more or less than 30% of target flow rate. If alarm persists, check for kinked or blocked tubing inside or outside the unit, or for leaks between the flow meter and the control valve.

5.3.3. Check for damage to the traces on the circuit board. Failure of an internal component can cause excessive power draw. This will typically result in burn marks adjacent to the eight-pin connector that can be observed with the back cover removed. Contact SeQual Customer Service for assistance. -

Page 29: Compressor Top-End Rebuild
6.5.18 Shut down unit and install covers. Compressor Top-End rebuild NOTE: Refer to Replacement Parts Section for proper rebuild kit. Contact SeQual Customer Service for all other compressor accessories. Compressor manufacturer instructions supersede SeQual’s if differences occur. NOTE: Experienced technicians with proper tools may elect to perform the compressor top end rebuild without removing the compressor from the unit. - Page 30 Service Manual Integra E-Z Oxygen Concentrators NOTE: Prior to installing the heat exchanger tubing into push lock fitting ensure that any sharp edges are removed to avoid cutting the O-ring and generating a compressor leak. A compressed air leak will cause the ATF performance to degrade quickly. This will result in premature unit failure.
