INSTALLING THE CONCENTRATOR
Materials and tools required:
g 6 mm hex key
g 3 mm hex key
g M5 crescent wrench
1. Lift up and balance the concentrator on the rim of the base.
2. Reconnect the concentrator monitor cable and the LED indicator panel cable.
3. The drain hose from the water trap must be pushed through the hole in the bottom of the concentrator.
4.
Push the concentrator into the housing, making sure that the drain hose does not get trapped between the bottom of
the concentrator and the rim of the housing.
5. Make sure that the oxygen outlet tube from the oxygen reservoir is not kinked. Also make sure that the water trap is not
damaged or dislodged by the top housing or by the foam on the right hand side of the housing. Realign it if necessary
after it is inside.
6. When the concentrator is placed approximately in its final position, align the rear right hand holes for the 6 mm hex
screw with a short screwdriver and loosely screw it in a few turns.
7. Align the rear left hand holes and loosely screw the second hex screw here. Then locate the remaining two front hex
screws and tighten all screws.
8. Connect the oxygen supply hose to the bottom of the pressure regulator making sure that it is not kinked.
9. Connect the concentrator power switch cable (4 wires: 2 blue, 1 yellow, 1 red).
10. Make sure that the battery wires are connected firmly to the battery on the rear panel (black to black, red to red)
11.
Insert the two air inlet hoses into the air filter and lift up the rear panel ensuring that the hoses bend downwards
between the zeolite cylinders and do not kink when closing the rear panel.
12. Attach the rear panel to the housing with the 6 screws.
NOTE:
When finished assembling verify that the drain hose is protruding from the orifice as picture below.
13. Test the oxygen concentration and flow of the concentrator and test that the control screen works on battery and that
the battery charges.
