LOW ALARM INDICATOR — The low alarm setting is displayed at all times just below
the “LOW” icon on the LCD readout. The indicated value represents the oxygen percent-
age at which the low alarm will be activated.
l
<18% ALARM INDICATOR — The <18% alarm indicator is located above the Low Alarm
Indicator digits. When the low alarm setting is set below <18%, the indicator will flash
each second to alert the operator of this special condition. See section 2.3.1 for setting

1.7 Requirements for Operating the Blender
All operator-detachable inlet pressure hoses supplied with the gas mixer comply with ASTM/
ISO 5359.
PRESSURIZED OXYGEN: The compressed oxygen source must provide clean, dry, medical-
grade oxygen at the pressure specified in Section 8.0.
PRESSURIZED AIR: The compressed air source must provide clean, dry, medical-grade air at
the pressure specified in Section 8.0.
2.0 OPERATING PROCEDURES
2.1 Setup and Installation
2.1.1 Battery Installation
All MaxBlend 2 units are powered by four “AA” alkaline batteries (4 x 1.5 Volts) and are shipped
without the batteries installed. Only name-brand batteries should be used. Batteries should
be replaced by trained service personnel.
To install the batteries:
Open the battery drawer by squeezing inward on both tabs as shown in the figure below. If
you have difficulty squeezing the tabs in with your fingers, use two flat screwdrivers or two
coins. Remove the battery drawer completely from the MaxBlend 2. Install four new, “AA”
alkaline batteries into the unit, observing the orientation shown on the plastic inside the
drawer. Slide the drawer back in with the batteries facing upward. Press in on the drawer until
both tabs latch into place.
When batteries are replaced, the unit will start up and perform an automatic calibration.
Ensure calibration is performed as directed in Section 2.8.
WARNING: Battery replacement by inadequately trained personnel could result in a
safety hazard.
WARNING: Electrical shock or damage to the equipment may occur if an inappropri-
ate external power supply is used. Maxtec recommends using only the Maxtec MaxBlend 2
External Power Supply—R230P10.
2.1.2 MaxBlend 2 Setup
1. Connect the pressurized air source to the Air Inlet Connector.
2. Connect the pressurized oxygen source to the O2 Inlet Fitting.
3. Flush gas at the highest possible flow rate through the blender for at least one minute
to eliminate any particulate that may have been introduced into the system during
handling and installation.
2.1.3 Sensor Installation
1. Attach the flow diverter onto the oxygen sensor.
2. Place the sensor into the sensor port located behind the flowmeter.
3. Attach the sensor cable directly to the sensor and the sensor jack on the back of the
monitor enclosure. Ensure the cable is fully inserted into both connections.
4. Calibrate the sensor prior to use according to the calibration procedures in section 2.8
2.2 Monitoring
Before use on a patient, the oxygen concentration of the delivered gas should be checked at
the setting intended for use.
1. To begin monitoring, press the ON/OFF key located on the front panel. Monitoring
will begin immediately.
