Cautions; Note; Contraindications - Philips RESPIRONICS System One User Manual

Cautions

A caution indicates the possibility of damage to the device.
• Do not place the humidifier directly onto carpet, fabric, or other flammable materials.
• Do not place the device in or on any container that can collect or hold water. Take precautions
to protect furniture from water damage.
• Do not fill the water tank above the maximum fill line. Damage to the humidifier or therapy
device may occur. If the water tank is overfilled, water may leak out of the tank inlet (located
on the back of the tank) when installing the tank lid.
• Never use water from a biologically unsafe source such as a lake, river, stream, or well.
• Philips Respironics recommends using room temperature distilled water in the tank, if
available, to prevent mineral build up on the water tank base.
• Do not put any chemicals or additives into the water. Possible airway irritation or damage to
the water tank may result.
• Remove the tank, empty all water, and replace the empty tank before transporting the
humidifier enclosure.
• Do not attempt to fill the water tank while it is still inside the humidifier.
• To avoid spilling, do not disconnect the humidifier from the therapy device with water in the
tank. Remove the water tank from the humidifier before disconnecting the therapy device.
• Do not turn the humidifier on without the water tank installed. The Humidifier setting must
remain "off" if there is no water in the water tank.
• The humidifier door must be set in the open position before removing the water tank. Do not
remove the water tank without making sure that the humidifier door locks into the open position.
• Do not move the humidifier while the water tank has water in it.
• Use a mild liquid dishwashing detergent only for hand washing.
• Only the hospital and institution cleaning procedures listed in this manual are recommended
by Philips Respironics. Use of other cleaning and disinfecting processes, not specified by
Philips Respironics, may affect the performance of the product.

This humidifier is an optional accessory to Philips Respironics therapy device and can only operate
