Humidifier parts
Refer to Illustration A on page 1.
Your heated Humidifier is made up of two main parts:
(1) docking station and (2) water chamber. Your docking station has the
following items (3) air outlet; (4) cover; (5) cover seal; (6) control dial; (7)
connector seal; (8) heater plate; (9) latch; (10) indicator light. Your water
chamber includes the (11) spill guard.
Setting up your humidifier for use
Refer to illustrations B & C on page 1.
Remove the connector plug from your flow generator (a) and attach it to
the back of the docking station (b).
1. Align your Humidifier with your flow generator and push together
until they click into place.
2. Connect the power cord to the socket on the rear of your flow
generator.
3. Plug the other end into a power outlet. Place the combined unit on
a firm, level surface near your bed at a level lower than your sleeping
position. Ensure the surface is not sensitive to heat and/or moisture, or
use a protective mat.
4. Connect one end of the air tubing firmly onto the air outlet.
5. Connect the assembled mask system to the free end of the air tubing.
WARNING
• Make sure your flow generator is disconnected from the power
outlet before connecting to docking station.
• The Humidifier docking station should only be connected or
disconnected when the water chamber is empty.
• Do not transport the flow generator with the Humidifier attached.
• The H4i is contraindicated for invasive use. An external humidifier
approved for invasive use is recommended according to EN ISO
8185.
Filling the water chamber

1. Open the cover.
2. Remove the water chamber.
3. Fill with fresh, clean water up to or below the maximum water level
mark.
Note: The water chamber must be removed from the H4i before it is filled
or water may enter the flow generator. The spill guard must also be in
place.
4. Return the water chamber to the docking station.
Note: Ensure that no water is collected between the heater plate and the
water chamber.
5. Close the cover ensuring that it clicks into place.
WARNING
Do not overfill the water chamber as water may enter the flow
generator and air tubing.
