WARRANTY

The MaxBlend 2 is designed for air/oxygen delivery. Under normal operating conditions, 

Maxtec warrants the MaxBlend 2 to be free from defects of workmanship or materials for a 

period of three years from the date of receipt from Maxtec, provided that the unit is prop-

erly operated and maintained in accordance with Maxtec’s operating instructions. Based on 

Maxtec’s product evaluation, Maxtec’s sole obligation under the foregoing warranty is limited 

to making repairs, or issuing credit, or replacement for equipment found to be defective. This 

warranty extends only to buyers purchasing new equipment directly from Maxtec, or through 

Maxtec’s designated distributors and agents. Maxtec warrants the MAX-550E oxygen sensor 

in the MaxBlend 2 to be free from defects in material and workmanship for a period of two 

years from Maxtec’s date of shipment in a MaxBlend 2 unit. Should a sensor fail prematurely, 

the replacement sensor is warranted for the remainder of the original sensor warranty period. 

Routine maintenance items, such as batteries, are excluded from warranty. Maxtec, and any 

other subsidiaries, shall not be liable to the purchaser or other persons for incidental or con-

sequential damages to  equipment that has been subject to abuse, misuse, misapplication, 

alteration, negligence, or accident. 

THESE WARRANTIES ARE EXCLUSIVE AND IN LIEU OF ALL  

OTHER WARRANTIES, EXPRESSED OR IMPLIED, INCLUDING WARRANTY OF MERCHANTABILITY 

AND FITNESS FOR A PARTICULAR PURPOSE.

NOTE: 

In order to obtain optimum performance from your MaxBlend 2, all operation and 

maintenance must be performed in accordance with this manual. Please read the manual 

thoroughly before using the MaxBlend 2, and do not attempt any repair or procedure that is 

not described herein. Maxtec cannot warranty any damage resulting from misuse, unauthor-

ized repair, or improper maintenance of the instrument.

EMC Notice

This equipment uses, generates, and can radiate radio frequency energy. If not installed 

and used in accordance with the instructions in this manual, electromagnetic interference 

may result. The equipment has been tested and found to comply with the limits set forth 

in IEC 60601-1-2 for medical products. These limits provide reasonable protection against 

electromagnetic interference when operated in the intended use environments described in 

this manual.

 MRI Notice

This equipment contains electronic and ferrous components, whose operation can be affected 

by intense electromagnetic fields. Do not operate the MaxBlend 2 in an MRI environment 

or in the vicinity of high-frequency surgical diathermy equipment, defibrillators, or short-

wave therapy equipment. Electromagnetic interference could disrupt the operation of the 

MaxBlend 2.

WARNINGS 

Indicates a potentially hazardous situation which, if not avoided, could result in death or seri-

ous injury.

The following warnings apply any time you operate 

or service the MaxBlend 2:

 

Always confirm prescribed flow before administering to patient and monitor flow on a 

frequent basis.

 

Always follow ANSI and CGA standards for medical gas products, flowmeters, and oxygen 

handling.

  DO NOT 

operate the MaxBlend 2 unless qualified personnel are in attendance to promptly 

respond to alarms, inoperative conditions, or sudden malfunctions.

 

Patients on life-support equipment should be visually monitored at all times.

 DO NOT 

ignore audible alarms of the MaxBlend 2. Alarms indicate conditions that require 

your immediate attention.

 DO NOT 

use parts, accessories, or options that have not been authorized for use with 

the MaxBlend 2. Using unauthorized parts, accessories, or options may be harmful to the 

patient or damage the MaxBlend 2.

 

Check all audible and visual alarms periodically to ensure they are operating properly. If 

an alarm fails to activate, contact your Maxtec Certified Service Technician.

 DO NOT 

operate the MaxBlend 2 with the monitor powered off or without setting the 

adjustable alarms. All adjustable alarms must be set to ensure safe operation.

 DO NOT 

steam autoclave or otherwise subject the MaxBlend 2 to temperatures above 

122°F (50°C).

 

If either the air or oxygen source pressure is reduced or increased sufficiently to create a 

pressure differential of 20 PSI or more, an audible alarm will sound. This condition may 

significantly alter the FiO2 and flow output from the MaxBlend 2.

 DO NOT 

tape, obstruct, or remove the alarm during clinical use.

 DO NOT 

occlude the sensor port on the side of the MaxBlend 2.

 

An air inlet/water filter is recommended for use with the MaxBlend 2. See section 6.1.

 DO NOT 

use lubricants on the MaxBlend 2.

 DO NOT 

use the MaxBlend 2 until correct performance has been verified. See section 3.0.
