This humidifier cannot be run off of 12 volt DC power. If a machine is powered by 12 volts, the heated humidifier will not run. A 110 volt pure sine inverter hooked to a 12 volt battery can be used to power an S8 CPAP and this humidifier.

This humidifier integrates with the full line of ResMed S8 and S8II Series CPAP/APAP/VPAP Machines. The H4i Heated Humidifier is not compatible with:

• AutoSet CS 2
• S7 AutoSet Spirit
• S7 Series
• VPAP III Series
• VPAP Malibu

VPAP III Series is not an S8 model and will only work with the HumidAire 2i Heated Humidifier.

The S8 AutoSet II and Elite II are compatible with this product, but the CPAP machines were manufactured BEFORE the H4i was manufactured. When setting either machine, please note that H3i will appear on the display.

Maximum Fill Level Tips

• 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.
• When disconnecting the hose from the tank outlet, be careful to ensure that the hose is not holding water. Water could travel through the hose and into the machine.
• Use only room temperature distilled water in the tank. 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 base.
• Do not attempt to fill the water tank while it is 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 number setting must remain on 0 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.

Please note: The manufacturer warranty is voided by water damage or misuse of the machine.
