DESCRIPTION
The BlenderBuddy 2 is an accessory designed for use with air/oxygen blenders. It utilizes a Maxtec
Designed for Blenders (DFB) flowmeter which is designed and calibrated specifically for air/oxygen
blenders to provide increased accuracy compared to standard flowmeters. By utilizing dual-scale gradu-
ations, the flowmeter provides two flowmeters in one for increased accuracy at lower flows. The flow-
meter features a high-quality acrylic block body and precision valve. The BlenderBuddy 2 also provides
a sensor analysis port which may be used to measure the gas concentration from the blender. A small
continuous sensor bleed is provided which enables gas analysis regardless of which outlet port is used
on the blender.
INTENDED USE
The BlenderBuddy 2 is a flowmeter intended for use with an air/oxygen blender and is to be used
by physicians, respiratory therapists and other authorized hospital personnel to administer selected
doses of medical gases to a patient The BlenderBuddy 2 also contains a gas analysis port which may
be used with a suitable oxygen analyzer to measure the gas concentration.
WARNINGS
!
 Read this User Manual before installing or operating the BlenderBuddy 2.
 This manual instructs a professional to install and operate the BlenderBuddy 2. This is provided
for your safety and to prevent damage. If you do not understand this manual, DO NOT USE the

 Use BlenderBuddy 2 only for its “Intended Use” as described in this manual.
 This product should only be used under proper supervision of a healthcare professional.
 The BlenderBuddy 2 is for use with air/oxygen blenders only. The accuracy of the flowmeter will be
affected if the BlenderBuddy 2 is used in any other way.
 Follow all manufacturer instructions for proper air/oxygen blender and bleed operation.
 ALWAYS activate the blender bleed when necessary according to the blender manufacturer instruc-
tions. Failure to do so may result in inaccurate concentrations from the blender.
 The flowmeter is capable of delivering flows greater than the indicated value (flush flow). Adjusting
the flow beyond the indicated range will result in an undetermined flow.
 The BlenderBuddy 2 is capable of delivering gas mixtures at pressures equal to the blender outlet.
Always confirm proper setup before patient use.
 Check for leaks and proper operation before placing the BlenderBuddy 2 into service.
 ALWAYS confirm prescribed flow and oxygen concentration before administering to patient and
monitor on a frequent basis.
 The BlenderBuddy 2 may contain magnetic, ferrous material and is NOT for use in MRI Environments.
DO NOT connect to source pressure greater than 100 psi.

1.0 INSTALLATION/OPERATION INSTRUCTIONS
NOTE: Low flow BlenderBuddy 2 models (3, 15 and 30 LPM) should only be used with Low Flow
blenders. High Flow BlenderBuddy 2 models (70 LPM) should only be used with High Flow blenders.
Use outside these applications may result in flowmeter inaccuracies.
ATTACH THE
BLENDERBUDDY
2 TO THE LEFT
SIDE DISS PORT OF
THE AIR/OXYGEN
BLENDER USING AN
11/16" WRENCH.
ALIGN THE FLOWMETER IN AN UPRIGHT, VERTICAL POSITION WITH
THE BLENDER AND FIRMLY TIGHTEN THE FITTING.
NOTE: Ensure the fitting is completely tightened to prevent rotation during use.
INSERT OXYGEN ANALYZER
WITH SENSOR DIVERTER
INTO THE SENSOR PORT TO
MEASURE THE DELIVERED
GAS FROM THE BLENDER.
NOTE: Use the sensor
diverter provided with your
BlenderBuddy 2 or genuine
Maxtec replacement.

WARNING
!
Follow all manufacturer instructions for proper blender bleed operation. A blender bleed is typically
required to maintain mixing accuracy for flows less than 3LPM on low flow blenders and below 15LPM
for high flow blenders. Failure to activate the blender bleed may result in inaccurate concentrations
from the blender.
NOTE: A small continuous sensor bleed is provided to the analysis port which enables gas analysis
regardless of which outlet port is used on the blender.
2.0 FLOWMETER OPERATION
Adjust the flowmeter to the desired set-point as read by the center of the float ball .
 To increase flow—turn knob counter-clockwise
 To decrease flow—turn knob clockwise
!
WARNING: The flowmeter is capable of delivering flows greater than the indicated (flush flow).
Adjusting the flow beyond the indicated range will result in an undertermined flow.
3.0 CLEANING & MAINTENANCE
3.1 Cleaning
Exterior surfaces may be cleaned using a cloth and mild detergent, isopropyl alcohol solution, or
germicidal wipe.
