The equipment consists of an oil-free piston compressor driven by a single-
phase electric motor, filtering and drying equipment, an air tank and a
pressure regulator. The compressor is placed in a box lined with noise
absorbing insulation. The equipment produces filtered compressed air
without any traces of oil with reduced water content (dry air).
The air compressor has an input air connector labeled WALL (9) that allows
the connection of an outside air source. When an outside compressed air
source is connected to the WALL inlet fitting supplies air above the adjusted
output pressure, the compressor will not be activated even though the power
switch is in the ON position. Instead, the air from the outside source will be
directed to the compressor's air output. When the outside air source pressure
is less than the adjusted output pressure (or is not connected) and the power
switch is in the ON position, the compressor is activated and supplies
compressed air through the air output.
The compressor pulls in atmospheric air through the suction filter (12).
Compressed air is cooled in the cooler (15), continues to the filter (14) and
condensed liquid from the water trap is automatically released to the
evaporation tray. The air continues through the check valve to the air tank
(11) and through the pressure regulator with the output filter (13) to the OUT
connector (10). Fans operate during compressor operation and when not
operating when the temperature in the cabinet is over 40°C (104°F). If the
temperature in the cabinet is over 80°C (176°F), a cooling failure is signaled
by the red indicator (3) and an acoustic alarm. Control electronics (16) control
compressor operation based on the pressure in the air tank (11). A safety
valve (17) ensure the maximum allowed tank pressure is not exceeded.

Connect the pressure hose from the given equipment/respiration equipment
to the quick coupling OUT (10) -outlet compressed air.
Connect the compressed air line from the central distribution line o the quick
coupling WALL (9) -inlet compressed air. Air from the distribution system is
automatically connected through the compressor to the OUT outlet port. In
this configuration, the compressor serves as a backup source of compressed
air. If the air pressure from the central distribution system is reduced, the
compressor automatically switches on and there is no interruption in the
supply of continuously pressurized air at the outlet of the compressor.
Please note that the air supply from the central distribution line
entering the compressor must be medical grade air (particulate size,
humidity.) The compressor does not modify the air from the central
distribution line.
The hose connecting the compressor to the respiration equipment
must not pass through a cold environment i.e. placed on the ground. It
should be as short as possible with no kinks (this may cause water to
condense inside the hose).
Electrical connection
The compressor comes with a plug containing an appropriate
protective contact (ground.) Adhere to local electrical regulations. The
voltage and frequency of the mains must comply with the
specifications on the data label.
The electrical cord must not be stressed or have any tension exerted
upon it, and must always be free.
•The socket must be accessible for safety reasons so that the equipment
can be safely disconnected in case of an emergency.
•The relevant current circuit must be protected.
