Section IV Operation
When power is applied, fresh air is taken in through
air fi lters and compressed by the pump pistons. The
compressed air is very warm and is cooled for use
by the heat exchanger and fan. Air is then delivered
to the coalescing fi lter to remove most of the
moisture.
The coalescing fi lter is equipped with an automatic
draining feature that allows the draining of the
excess moisture. The cool air enters the desiccant-
style dryer assembly to complete the moisture
removal by removing 99.7% of the water vapor from
the air.
Air is directed into the dryer cartridges, from one
to the other, by electronically controlled solenoid
valves. The timing for the solenoid valves is provided
by an electronic timing board on the basic models or
the C2 control on the smart models.
While the air is moving through one cartridge, the
desiccant in the other cartridge is being dried by air
directed through an ori fi ce in the outlet shuttle valve.
This valve cycle will be noticeable by a short burst of
air from the purge valves. It is then collected in the
tank where it is stored for future use.
A pressure gauge on the basic model and the C2
control panel on the smart model displays the tank
air pressure. When air is called for to run equipment
in the facility, it goes through a particulate fi lter to
remove any remaining particulates from the air.
The tank pressure is monitored by a pressure switch
on the basic models with the operating pressure
from 85 to 115 PSI. Pressure adjustment is not
recommended and will void the warranty. The smart
models are monitored by a pressure transducer in
the C2 control, which runs the motors on demand.
Pressure is factory set from 85 to 115 PSI and is not
adjustable.
Theory of Operation Getting Started
The Osprey compressor is easy to operate and
maintain.
1. Verify the compressor is connected to a
dedicated circuit.
2. Verify the compressor is properly connected to
the facility plumbing and a fresh air source.
3. Verify the shut-o ff valve is closed.
4. Start the compressor.
• Basic model: turn the pressure switch toggle
from OFF to AUTO .
• Smart model: push the START button on the
C2 control panel.
NOTE: If the compressor is controlled by the OWL
Touch, it cannot be started by the C2 control.
5. Test for leaks. (See Section IV Care - Test
Compressor for Leaks .)
6. Turn the shut-o ff valve to OPEN .
WARNING
Never direct the air stream toward any
portion of the body or others in the vicinity.
Pressurized air streams can be extremely
hazardous to your healt and can result in
death in certain circumstances.
DO NOT attempt to operate the compressor at
ambient temperature below 35°F/0°C or above
104°F/40°C.
