Small Magnet: Placed on the intensifier center drive
section to visually indicate intensifier operation.
–The intensifier's piston travels up and down to
NOTE
within ¾" of the top and bottom of the drive section. If the
piston (magnet) stops or takes longer than 9 seconds to
travel one way, the unit will shut off and alarm.
–Always remove the magnet after troubleshooting

and repair.

Stopwatch or watch with a second hand
Do first:
•
Visually inspect unit for physical damage
•
Secure any loose wire and tubing connections
–The tubing from the three-way valve must be

connected to the top port of the OSD or random shut
down occurs that is difficult to troubleshoot.
•
Warm up the unit and duplicate the problem twice.
–A cold unit, or one that has just been plugged in,
NOTE
will alarm and react differently which may make
troubleshooting more difficult.
knowledge:
•
Become familiar with the names and locations for all
components
•
If the oxygen purity does not come up to specification
(91%) during a continuous 11 minute run in warm up, the
unit will shut off and alarm .
•
After the first 70 seconds from startup, if the flow to the
OSD is below 1 .5 lpm, the unit will shut off and alarm .
•
If the intensifier has a leak or the oxygen concentrator
portion of the unit is not performing correctly, the unit may
constantly transition in and out of the warm up mode
causing extended fill times.
–Occasionally the unit will go back into warm up
NOTE
mode for a short period during the early portion of a
cylinder filling cycle. This is most common when filling an
empty cylinder.
o
To troubleshoot, use a flow test fixture that allows a
maximum flow of 3 lpm. Remove the tubing from the
top metal fitting of the three-way valve and install the
tubing from the flow test fixture in its place.
o
If the unit no longer transitions in/out of warm up,
either the tubing to the intensifier is leaking or the
intensifier itself is faulty.
–The three-way valve will make a clicking sound
NOTE
every 24 seconds indicating the unit is in its normal fill
cycle. This clicking sound will not be heard during the
warm up mode.
o
If the unit continues to transition in/out of warm up, the
concentrator portion is not performing correctly . Check
for leaks, faulty sieve beds, faulty rotary valve, etc .
•
If the unit is running and not constantly transitioning in and
out of warm up mode, but does not fill a cylinder, the
problem is the intensifier. Ensure that there are no system
leaks and that the cylinder and regulator or conserver is
not leaking .

performance test:
Before returning to service, the iFill Station should be tested to
ensure it is operating properly. This can be done by filling a
cylinder and then testing the oxygen concentration from the
cylinder . Refer to steps 4-8 listed under Initial Inspection . It is
recommend that the cylinder be filled completely before testing
concentration level. This will allow for verification of fill time for
the repaired iFill station .
