Hello, i have a question, in the service manual of SLE 5000 HF ventilator talks about an ETU-2 device, what is that device? i need calibrate this ventilator, but i read that couldn`t realize the service whitout that device. Thanks in advance.
*DO NOT PRESS FLOW CALIBRATION IN THE SERVICE SCREEN!!!* You will render the ventilator unuseable. The ETU device is used in manufacture only and Flow calibration should not be initiated in the field. assuming you are untrained i cannot advise you other than to contact SLE themselves. This ventilator is a particularly difficult device to calibrate and service for anyone who has not been technically trained by SLE themselves.
