InTended use
e M Series Heated Humidifier is an accessory for M Series positive pressure ventilation systems
to provide moisture to the patient circuit. It is intended for use in spontaneously breathing patients
weighing over 30 kg, in the home or hospital/institutional environment, who use mask-applied
positive pressure ventilation therapy.
WarnIngs and CauTIons
WarnIngs
A warning indicates the possibility for injury to the user or the operator.
• Use the humidifier only for its intended use as described in this manual. Use only
accessories recommended by Respironics.
• Never operate the humidifier if any of the parts are damaged, if it is not working
properly, or if the humidifier has been dropped or mishandled. Do not use the
humidifier if the water tank is leaking or damaged in any way. Have any damaged
parts replaced before continuing use.
• Allow the device to cool down before touching or removing the water tank.

 M Series Heated Humidier
• is equipment is not suitable for use in the presence of a flammable anesthetic mixture
with air or with oxygen or nitrous oxide.
• Periodically inspect the humidifier power supply connector, power supply cord
connector, and the AC power cord for signs of wear or damage. Replace the power
supply and AC power cord if worn or damaged. If the humidifier power supply
connector is worn or damaged, contact Respironics or your home care provider.
• When installing the water tank, do not allow any water to spill into the humidifier or
therapy device.
• Pins of connectors identified with the ESD warning symbol ( ) should not be
touched. Connection should not be made to these connectors unless ESD precautionary
procedures are used. Precautionary procedures include methods to prevent build-up of
electrostatic discharge (e.g., air conditioning, humidification, conductive floor cover-
ings, non-synthetic clothing), discharging one’s body to the frame of the equipment
or system or to earth or a large metal object, and bonding oneself by means of a wrist
strap to the equipment or system or to earth.
CauTIons
A caution indicates the possibility of damage to the device.
• If fluids are spilled onto the humidifier base, unplug the power cord from the AC
wall outlet and allow the humidifier platform to drain and dry before using.
• Take precautions to protect furniture from water damage.
• Do not fill above line.
• Remove tank, empty all water, and replace empty tank before transporting the
humidifier base.
NOTE: Additional warnings, cautions, and notes are located throughout this manual.

IMPORTANT! Read and understand your therapy device’s manual prior to using this
humidier with your therapy device.
ConneCTIng The Therapy devICe
1. When using a humidifier, the patient circuit attaches to the air outlet port on the humidifier.
If your therapy device has the air outlet port connection attached, you must remove it from your
therapy device before connecting to the humidifier.
To remove the port:
a. Put your thumb underneath the port and insert your index finger into the port opening.
b. Pivoting from the bottom, unsnap the port and pull it away from the device.

TravelIng WITh The sysTeM
paCKIng The sysTeM
When you are traveling, the optional M Series carrying case can be used for carry-on luggage only.
e carrying case will not protect the humidifier if it is put through checked baggage.
CAUTION: Always empty the water tank before packing the humidier.
For your convenience at airport security stations, there is a note on the bottom of the humidier
stating that it is medical equipment. It may be helpful to bring this manual along with you to help
security personnel understand the device.

dC poWer
is humidifier is suitable for use with typical DC-to-AC inverters and UPSs (uninterruptible power
supplies). (200 watts at 120 V and 400 watts at 220 V)
e Respironics DC Power Cord can be used to operate the therapy device and humidifier in a
stationary recreational vehicle, boat, or motor home. e Respironics DC Battery Adapter Cable,
when used with the DC Power Cord, enables the device to be operated from a 12 VDC free-standing
battery.
NOTE: When the DC Power Cord is used, the humidier will not heat up unless it is also
plugged into an inverter. The blue LED will ash when the heater plate does not heat
up. In this mode, the humidier acts as a passover, or non-heated, humidier.
CAUTION: When DC power is obtained from a vehicle battery, the device should not
be used while the vehicle’s engine is running. Damage to the vehicle or the
device and humidier may occur.
CAUTION: Only use a Respironics DC Power Cord and Battery Adapter Cable.
Use of any other system may cause damage to the device or vehicle.
Refer to the instructions supplied with the DC power cord and adapter cable for information on how
to operate the therapy device and humidifier using DC power.
InTernaTIonal Travel
If you are traveling to a country with a line voltage different than the one you are currently using,
a different power cord or an international plug adapter may be required to make your power cord
compatible with the power outlets of the country to which you are traveling. Contact your home
care provider for additional information.

probleM Why IT happened WhaT To do
Nothing happens
when you apply
power to the
humidier.
Loss of AC/DC power or
the device is unplugged.
Following the Daily Use section earlier in this
manual, check the outlet power and verify that
the humidier and therapy device are properly
plugged in. Make sure the AC power cord is
connected correctly to the power supply and
the power supply cord is correctly plugged into
the wall. Check if the blue LED is blinking. If it is
blinking, follow the steps under The Blue LED is
Blinking problem on page 0 of this manual.
If the problem continues to occur, contact your
home care provider. Return the humidier, ther-
apy device, and power supply to your provider,
so they can determine if the problem is with the
therapy device, humidier, or power supply.
The humidier
door has become
detached from
the device.
The door may come off if
the humidier is dropped
or mishandled.
The device will continue to function properly
without the door attached.
To reattach the door, make sure it is properly
oriented with the humidier, and then snap the
door back into place.
If the humidier does not operate properly after
being dropped or mishandled, contact your
home care provider or Respironics.
The humidier
is cracked or
damaged.
The humidier was
dropped or mishandled.
If the humidier does not operate properly after
being dropped or mishandled, contact your
home care provider or Respironics.
