Before installing the OGSI Oxygen Generator, it is necessary to consider the
location, space available and power supply for the generator.
1) Locating the OG-15/OG-20:

The oxygen generator should be located in an area that is indoors and remains
between
40

F ( 5

C ) and 100

F ( 38

C ). Setting up the machine outdoors or
in an area that is not normally within this temperature range will void the
OGSI Warranty.

There should also be a distance of at least 8 in ( 20 cm ) between the unit and
any side wall in the room that it will be located in. This is to ensure that
airflow into the machine through the cooling fans is not restricted.

(OG-15E/OG-20E Compressor-less Only) The machine must be located
within reach of an air supply line, as this machine requires an external pre-
existing source of pressurized air.
2) Space Available for the OG-15/OG-20:

If the OG-15/OG-20 unit is going to be set up in a room that is small, (less than
1000 ft
3
or 28.3 m
3
), that room should be well ventilated (at least 5 air changes
in the room per hour). The oxygen generator will be discharging nitrogen into
the atmosphere of the room and a nitrogen build up could be dangerous to
people entering the room. If the generator is placed in a small closet, the air in
that closet will become enriched with nitrogen. As the oxygen generator
continues to operate, it would become more and more difficult for it to separate
the oxygen from the air because oxygen will make up a smaller and smaller
fraction of the air that is fed into the oxygen generator.
3) Power Supply for the OG-15/OG-20:

The oxygen generator should be positioned within 8 ft ( 2.2 m ) of the electrical
outlet that will power it. The reason for this is that the motor draws a large
current during the first few seconds of start-up.
It is also very important for
this reason NOT to use any extension cords with the unit. They could
overheat and melt, possibly causing a fire. The electrical outlet system to
which the
OGSI oxygen generator is connected should be used exclusively for
that purpose and no other electrical appliances should be connected to it.
