Operating Instructions – Filling
1. Clean the fill connectors on the H300/H850 and the reservoir with a
clean, dry, lint-free cloth.
WARNING: The fill connectors must be clean and dry
with a lint-free cloth on both the stationary and portable
units to prevent freezing and possible equipment failure.
2. Turn the flow control knob on the H300/H850 to the off ("0")
position.
3. Hold the H300/H850 with both hands and position its fill connector
over the reservoir fill connector.
4. Lower the portable onto the reservoir until you feel the connectors
engage.
5. Place one hand on top of the H300/H850 and apply a constant
downward force.
6. Open the vent valve by pulling downward on the vent valve lever to
begin the filling process. You will hear a hissing sound that is perfectly
normal.
7. You may see vapor around the fill connection. This is normal due to
the great difference in temperature between the liquid oxygen and the
warm surrounding air.
8. Maintain a downward force on the H300/H850 with one hand during
the entire filling process and keep the vent valve lever open with the
other hand.
9. Approximately 20-30 seconds into the fill, close and re-open the vent
valve one or more times. This will prevent the valve from freezing open.
10. The unit is full when the hissing sound changes in tone and a dense
HELiOS
TM
white vapor is seen coming from under the shroud of the reservoir.
When this is observed, close the vent valve by raising the vent valve
lever. This will terminate the fill.
11. Hold the handle on the H300/H850 and push the release button on
the reservoir until the portable separates (release button varies by model
of reservoir).
12. Check the contents indicator to verify that the unit is full.
Caution: If the H300/H850 does not separate easily, do
not use force. The units may be frozen together. Leave the
units connected and wait until they warm up – then they
will separate easily. Do not touch any frosted parts.
Caution: Should there be any liquid leakage from the
portable after separating the units, reattach the H300/
H850 to the reservoir immediately. Again, separate the
units. If the problem persists, leave the units attached and
call your health care provider immediately.
Caution: Should there be any liquid leakage from the
reservoir after separating the units, immediately place a
dry towel over the reservoir. Open windows in the room
and call your health care provider immediately.
Caution: Check the liquid level only after the vent valve
is closed.
WARNING: Do not operate the H300/H850 while
attached to the reservoir unit.
WARNING: Should leakage be excessive to the point that
a stream of liquid is present, leave the area and call your
health care provider immediately.
Caution: If the H300/H850 is being refilled immediately
after a period of use, fill it, and then wait approximately
30 minutes after filling with the flow control knob set to off
("0") for the pressure to stabilize. Then operate as normal.
NOTE: If the HELiOS portable is warm or has not been filled
recently, it may take up to 90 seconds to fill an H300 or up to
4 minutes to fill an H850.
