System Setup

1Align your H4i with your flow generator and push them together until they click into

place.

2Connect the power cord to the socket on the rear of your flow generator.

3Plug the other end of the power cord into the 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.

4Connect one end of the air tubing firmly onto the air outlet.

5Connect the assembled mask system to the free end of air tubing.

WARNING

•Make sure your flow generator is switched off at the power outlet before

connecting the H4i.

•The H4i docking station should only be connected or disconnected when the

water chamber is empty.

•Water must be prevented from entering your flow generator. Do not

transport the flow generator with the H4i attached.

3Setting up your H4i for use

English

Filling the Water Chamber

1Open the cover.

2Remove the water chamber.

3Fill with fresh, clean water up the maximum water level mark.

4Return the water chamber to the docking station.

5Close 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.

CAUTION

Do not use any additives (eg, scented oils and perfumes). They may reduce the

humidification output of the H4i and/or cause deterioration of the water

chamber materials.

Detaching your H4i

1Unplug the power cord from the power outlet.

WARNING

Take care when handling your H4i. The water and the water chamber base may

both be hot. Allow 10 minutes for the heater plate and any excess water to cool.

2Remove the water chamber from the docking station.

3Press the large silver button located midway underneath the docking station.

4Pull the H4i and flow generator apart.

Note: Re-attach the connector plug firmly to your flow generator.

Starting and Stopping Treatment

Warming your H4i

The Warm-Up feature (not available on all ResMed PAP devices) is used to pre-heat

the water before starting treatment. Skip this step if you want to start immediately.

To start the Warm-Up feature:

1Select warmup by pressing on the control panel.

2The WARMING screen will appear to indicate that the Warm-Up feature is activated.

3While your H4i is in Warm-Up mode you can:

•Start treatment at any time by pressing .

•Access the menus by pressing .

•Stop the Warm-Up feature at any time by pressing . (This may not apply

on all devices.)

The Warm-Up feature will automatically turn off after 30 minutes if treatment has not

started.

Starting your treatment

1Turn the humidity control dial to three ( ). You can adjust the control dial up or down

at any time to find the setting that is most comfortable for you. The setting

switches heated humidification off and delivers minimum humidification while a

setting of six ( ) delivers maximum humidification.

Note: The ResMed Tubing Wrap is designed to enhance comfort by maximizing

heat retention along the air tube.

2Fit your mask as described in your mask user instructions.

3Press on the control panel to begin therapy.

Note: The H4i is thermostatically controlled to maintain a constant temperature. The

indicator light will brighten to indicate when the device is actively heating and dim

when it has reached its set temperature.

4Lie down and arrange the tubing so that it moves freely when you turn in your sleep.

WARNING

Do not leave an excessive length of air tubing around the top of your bed. It

could twist around your head or neck while you are sleeping.

Stopping your treatment

To stop your treatment, remove your mask and press .

Note: In order to assist the heater plate in cooling, some flow generators continue to

blow air gently for up to an hour after treatment has stopped. However, you can

unplug the device from the power outlet at any time and allow the heater plate to

cool without airflow.

5Cleaning and Maintenance

English

Cleaning and Maintenance

You should regularly carry out cleaning and maintenance of the water chamber, cover

and cover seal as described in this section.

WARNING

•Beware of electrocution. Do not immerse your flow generator, docking

station or power cord in water. Always unplug the device before cleaning

and be sure that it is dry before plugging it back in.

•Take care when handling your H4i. The water and the water chamber base

may both be hot. Allow 10 minutes for the heater plate and any excess water

to cool.

Disassembling the H4i

1Discard any excess water from the water chamber.

2Detach the air tubing from the air outlet.

3Remove the cover by gently flexing one cover arm away and up from the docking

station until the cover detaches completely.

Wash the water chamber, tub plate and tub plate seal in warm water, using a mild

detergent. Use the yellow cleaning plug to assist in the cleaning process (see steps

1 to 4). Rinse thoroughly in clean water and allow them to dry away from direct

sunlight.

123 4

Weekly

Inspect the water chamber for wear and deterioration. Replace the water chamber if

any component has cracked, become cloudy or pitted. Replace immediately if there

is any leaking from the water chamber.

White powder or deposits in the water chamber can be cleaned using a solution of

one part vinegar to 10 parts water, as follows:

1Fill the cleaning plug to the rim with vinegar and pour into empty water chamber.

2Add clean water to the water chamber until the solution reaches the maximum water

level mark.

3Let the solution soak for 10 minutes.

4Discard the solution and rinse the water chamber with clean water.

Cover and Cover Seal

Inspect the cover and cover seal weekly for wear and deterioration. Replace any

damaged parts. When required, wash the cover and cover seal in warm water, using

a mild detergent. Rinse them thoroughly with clean water and allow it to dry away

from direct sunlight.

Docking Station

Periodically wipe the outside of the docking station (including the connector seal) with

a damp cloth.

CAUTION

•Do not use any of the following to clean any part of the H4i as these

solutions may cause damage and reduce the life of the product:

– bleach, chlorine-, alcohol- or ammonia-based solutions

– moisturizing, antibacterial or glycerine based soaps

– water softening and unapproved descaling agents.

•Do not wash the water chamber in a dishwasher.

7Cleaning and Maintenance

English

Reassembling the H4i

Reassemble the parts when they are clean and dry.

1Align the cover seal to the guides on the cover and press along the edges to ensure

it is fitted properly.

2Put one cover arm into its pivot point on the docking station and gently flex the other

arm into its corresponding point. The cover should be able to open and close freely

while securely attached to the docking station.

3Replace the water chamber in the humidifier docking station.

Servicing

The H4i should be inspected by an authorized ResMed Service Center five years from

the date of manufacture. Prior to this, the device is intended to provide safe and

reliable operation provided that it is operated and maintained in accordance with the

instructions provided by ResMed. Warranty details are provided with the device at the

time of original supply. As with all electrical devices, if any irregularity becomes

apparent, you should exercise caution and have the device inspected by an authorized

ResMed Service Center.

Frequently Asked Questions

Question Answer

Why is there

condensation in

my mask and/or

air tubing?

Excessive condensation in your mask or air tubing may occur when the room

temperature is low. To prevent condensation, turn the control dial down to a lower

setting. You may need to adjust your humidity setting from season to season. The use

of a ResMed Tubing Wrap can help reduce the effects of condensation.

Do I have to use

distilled water

in the water

chamber?

Using distilled water will maximize the life of the water chamber and reduce mineral

deposits.

What if I still

have symptoms

of dryness?

If you have symptoms of dryness, then your humidity setting may be set too low to be

effective. Turn the humidity control dial up.

If you are still experiencing symptoms of dryness, you may be breathing through your

mouth. Mouth breathing or mouth leaks cause drying and irritation of the upper airway.

If this is a problem, a full face mask or chin strap may help. Consult your clinician or

equipment supplier for details.

If there is a problem, try the following suggestions. If the problem cannot be solved,

contact your equipment supplier or ResMed. Do not open the unit.
