M Series Heated Humidier
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 humidier 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 humidier acts as a passover, or non-heated, humidier.
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 humidier 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.
