How to operate Invacare Perfecto2?

How to set up Invacare Perfecto2 Home Oxygen Concentrator Humidifier?

  1. Remove cap from bottle.
  2. Fill a humidifier with boiled tap water or bottled water to the level indicated by the manufacturer. Boil tap water for approximately ten minutes and cool to room temperature prior to use.

  4. Pull up and remove the humidifier bottle adapter.
  5. Attach the humidifier bottle adapter to the humidifier bottle by turning the wing nut on the humidifier bottle counterclockwise until it is securely fastened.
  6. Select the location for the humidifier bottle/adapter assembly:
    When placing the humidifier bottle in the compartment on the Invacare Oxygen Concentrator, attach the humidifier bottle/adapter tube to the oxygen outlet connector on the concentrator. When using tubing connections longer than 7 ft (2.1 m) in length, position the humidifier as close to the patient as possible to allow for maximum humidification output.
  7. Attach the nasal cannula supply tube to the humidifier bottle outlet.
  8. After assembly, ensure that oxygen is flowing through the nasal cannula.

Flowrate of Invacare Perfecto2

  1. Turn the flowrate knob A to the setting prescribed by your physician or therapist.
  2. If the flowrate on the flowmeter ever falls below 0.5 L/min D for more than about one minute, the Potential Obstruction Alert will be triggered. This is a rapid beeping of the audible alarm. Check your tubing or accessories for blocked or kinked tubing or a defective humidifier bottle. After rated flow is restored to between 0.5 L/min and 0.75 L/min, the Potential Obstruction Alert will turn off.

SensO2 Oxygen Purity Indicator

This feature monitors the purity of oxygen generated by the oxygen machine. If purity falls below factory preset standards, indicator lights on the control panel will illuminate.

Initial Startup of the Perfecto2 v Oxygen Concentrator

When the unit is turned on, the yellow light will come on indicating the unit is operating and is in the initial warm-up period. When the green light comes on, the unit is in the normal operating mode (SYSTEM OK/O2 greater than 85%). Once in normal operating mode, the lights will be controlled depending on the oxygen concentration values.

Linda Lampman     10/19/2019

How do I push circuit breaker reset after power outage. The button doesn't push in.


Customer Care    10/21/2019

  • Turn off the light switches and unplug appliances in the room that has lost power. 
  • Find your circuit breaker box and open the cover. Locate the tripped breaker. 
  • Circuit breakers are small, usually horizontal switches labeled by the areas of the house they serve (for example, ""kitchen,"" ""bathroom"" and so on). 
  • The tripped circuit breaker will be in the "off" position or in a middle position between ""on"" and off."
  •  Reset the breaker by moving it to the full "off" position and then back to on. That may clear an overload and return power to the room.
  •  If the breaker re-trips, you may have too many lamps and appliances plugged into the circuit; a damaged cord or plug; a short circuit in a receptacle, switch or fixture; or faulty wiring.
  •  Identify and correct the malfunction before resetting the breaker.
