CHAPTER 1: INTRODUCTION
Theory of Operation
This section covers the theory of operations of the system.
The purpose of the Air Breathing System is to produce breathing air that meets Grade
D/E of the CGA breathing air standard G-71 and National Fire Protection Association
(NFPA) 1989. The production of high-pressure breathing air can be divided into four
(4) categories:
•
Compression - Air compression is accomplished using a multi-stage compressor
assembly. This is performed by the Compressor unit.
•
Purification - Air purification is accomplished by using a mechanical filtration and
chemical purification process. This is performed by the Compressor unit.
•
Storage - Compressed and purified air is stored in ASME cylinders for use later.
This is performed by the Storage unit.
•
Charging - Compressed and purified air is filled into breathing air cylinders. This
is performed by the Charge Station unit.
– The Compressor's role: The compressor, takes in ambient air that is filtered and
then compressed in five stages. Each stage is equipped with a standard safety
value, set slightly above the normal working pressure of that stage. The value
releases high pressure air to protect the system in case of mechanical failure.
These pressures are displayed, depending on the model, on the analog gauges
or virtual gauges on the HMI. Moisture separators continuously remove
moisture from the compressor intercooler and after-cooler air circuits. The
condensate container collects the moisture from the moisture separators. The
container is drained as needed. When the discharge pressure reaches the
maximum preset level, the compressor is unloaded. After the pressurized air
leaves the compressor, it passes through a multi-stage purification system. The
number of stages depends on the horse power, and therefore the air output
capacity of the compressor. The higher the air output, the more purification
elements are needed. The purification system further dries the air and removes
other impurities. From the purification system, the air can go directly to
charging breathing air cylinders, or can be sent to high pressure storage
cylinders and maintain the pressure in the storage for charging several
breathing air cylinders before the compressor restarts to refill the storage.
– The Storage Unit’s role: Once the breathing air is compressed and purified, it
may be sent to high pressure storage cylinders and maintain the pressure in the
storage for charging several breathing air cylinders before the compressor
restarts to refill the storage. The storage may be up to four (4) ASME vertical
cylinders.
– The Charge Station’s role: Once the breathing air is compressed and purified, it
may be filled directly into breathing air cylinders using the charge station. The
charge station allows the simultaneous filling of two (2) cylinders while two (2)
additional cylinders can be attached and made ready on the outside of the
chamber.

Locating the Charge
Station
This section covers locating and securing the devices.
Depending on the specific customer order the devices may vary.
This section covers the selection of a proper location for the Charge Station.
Warning: Make sure there is nothing close to or on top of the Charge Station that
could interfere with normal operations. For proper operation, the minimum clearance
of 24” must be established at installation on all sides and above the Charge Station
and must be maintained.
Securing the Charge
Station
This section covers securing the Charge Station. Each Charge Station ships with 4
bolts used to secure the device. The bolts are inserted through the devices feet into
concrete. The bolts are 58113 HH Wedge Anchor GR5 Z (5/8-11 X 3 Hex Head
Wedge Anchor Bolt Grade 5 Zinc).
Warning: The Charge Station must be anchored to the floor using the supplied bolts.
Failure to do so could result in injury or death.
Locating the
Compressor
This section covers the selection of a proper location for the Compressor.
Ensure the following items are adhered to when selecting a proper location:
•
•
•
•
•
A relatively clean, debris free and dry shelter
Sufficient ambient air for compressor cooling
A sufficient source of clean, compressor intake air
An appropriate power supply
An appropriate means to handle the water/oil mixture discharged from the auto
drain reservoir
A debris free environment is important because the Compressor draws cooling air
near floor level. Paper, dust, and other light-weight items allowed under the device
might be entrained in the cooling air stream and be drawn into the device. Large
objects might cause compressor fan damage or impede heat transfer efficiency which
could lead to a multitude of mechanical problems.
Since the Compressor is an air-cooled device, the heat of compression is rejected to
the surrounding air. It is important to locate the device in a very large room or provide
enough ventilation to maintain cooling air temperature below 100°F.
It is desirable to locate the Compressor in an environment free of high CO, CO2, and
other air contaminants. When the environment is less than desirable, provisions
should be made to permit the connection of an external source of air.
Warning: Make sure there is nothing close to or on top of the Compressor that could
interfere with the air flow. For proper operation, the minimum clearance of 24” must
087-0067 REV A

be established at installation on all sides and above the Compressor and must be
maintained.
Warning: Make sure nothing is operating in the vicinity of the Compressor air intake
which might contaminate fresh air supply. Such as: vehicle exhaust, chimney smoke,
ventilator fumes, or other source of contamination.
Securing the
Compressor
Securing the Storage
Unit
This section covers securing the Compressor. The Compressor is equipped with 4
adjustable feet.
This section covers securing the Storage Unit. Depending on the Storage Unit ordered.
Some ship with 4 bolts used to secure the device. The bolts are inserted through the
devices feet into concrete. The bolts are 58113 HH Wedge Anchor GR5 Z (5/8-11 X 3
Hex Head Wedge Anchor Bolt Grade 5 Zinc).
Warning: When applicable, the Storage Unit must be anchored to the floor using the
supplied bolts. Failure to do so could result in injury or death.

CHAPTER 2: INSTALLATION
Wiring the Devices
This section covers wiring the various devices. Specifically, Figure 4 shows an
overview of the required power to be supplied by the end user for the system.
Caution: This product has more than one connection to the source of supply. To
reduce the risk of electrical shock, disconnect all such connections before servicing.
This product must be connected to a ground, metallic, permanent wiring system, or an
equipment-grounding terminal or lead on the product.
This product must be grounded. In the event of an electrical short circuit, grounding
reduces the risk of electric shock by providing an escape wire for the electric current.
This product is equipped with a cord having a grounding wire with an appropriate
grounding plug. The plug must be plugged into an outlet that is properly installed and
grounded in accordance with all local codes and ordinances.
Warning: Improper installation of the grounding plug is able to result in a risk of
electric shock. When repair or replacement of the cord or plug is required, do not
connect the grounding wire to either flat blade terminal. The wire with insulation
having an outer surface that is green with or without yellow stripes is the grounding
wire.
This device uses a grounded cord-connection rated less than 15A and is intended for
use on a nominal 120V supply circuit. Only connect the device to an outlet having the
same configuration as the plug. Do not use an adapter with this device.
Check with a qualified electrician or serviceman when the grounding instructions are
not completely understood, or when in doubt as to whether the product is properly
grounded. Do not modify the plug provided; if it does not fit the outlet, have the
proper outlet installed by a qualified electrician.

CHAPTER 4: OPERATION
Compressor Overview
087-0067 REV A
In general, takes in ambient air and converts it into breathing air by way of various
subsystems as outlined here:
•
Electrical subsystem - Electrical current (VAC) is used to power a motor inside the
compressor that drives the compressor through a vee belt.
•
Filter and compression stages - The compressor, takes in ambient air that is filtered
and then compressed in five stages. Each stage is equipped with a standard safety
value, set slightly above the normal working pressure of that stage. The value
releases high pressure air to protect the system in case of mechanical failure. These
pressures are displayed, depending on the model, on the analog gauges or the HMI.
•
Fan - The air circulating fan mounted on the flywheel is used to blow cooling air
through the five stage air coolers and over the compressor head cooling fans. Air
passing through the air coolers serves to lower the air temperature in increase
compressor efficiency.
•
Moisture separators - Moisture separators continuously remove moisture from the
compressor intercooler and after-cooler air circuits. During normal operation, the
dump solenoid values are activated automatically every 15 minutes. The
condensate container collects the moisture from the moisture separators. The
container is drained as needed.
•
Discharge pressure achieved - When the discharge pressure reaches the maximum
preset level, the compressor is unloaded. The moisture traps open, and the
compressor continues to run without compressing air. Prior to stopping, the
compressor runs unloaded through a cool-down cycle while draining the moisture
separators and cooling down the compressor stages. This prevents the
development of rust in the compression cylinders and also provides for an
unloaded compressor restart.
•
Purification process - After the pressurized air leaves the compressor, it passes
through a multi-stage purification system. The number of stages depends on the
horse power, and therefore the air output capacity of the compressor. The higher
the air output, the more purification elements are needed. The purification system
further dries the air and removes other impurities. After this, the breathable air
may go directly to a charge station, to fill SCBA cylinders, or may be sent to
ASME high pressure storage cylinders.
SCOTT SAFETY
Compressor Overview
Compressor
Interfaces

This section covers the compressor interfaces. The operation of the compressor varies
based on the model. The Scott models use a HMI to operate the compressor. See
“Configuration and Setup” on page 21. Other models do provide analog gauges, but
do not provide a touch pad controller.
Warning: When settings are changed, ensure those changes are communicated to all
affected personnel.
Depending on the configuration, the compressor may be controlled via the HMI. In
general, the HMI is used to start and stop the compressor and to provide information
about the compressors’ operation, performance and conditions to the operator.
Figure 29 shows an example of a compressor screen.
For more details, See “Configuration and Setup” on page 21.
Figure 29 Compressor Screen Example
Compressor Process
This section provides a general overview of the compressor process, as each model
varies.
Warning: Never leave the Stationary Air Compressor system unattended while the
compressor is in use. A Scott trained and certified operator must monitor the system
gauges at all times and take immediate action to guard against equipment failure. This
equipment is intended for providing breathable air to save lives. Failure to monitor
the system may lead to permanent equipment damage, serious personal injury or
death.
Warning: Hearing protection may be required when using the Stationary Air
Compressor system for extended periods of time. Refer to the personal safety

guidelines or requirements of your organization. Exposure to high sound levels may
cause temporary or permanent hearing loss in some individuals.
Caution: Verify the correct compressor rotation before operation. Rotation should be
counterclockwise when facing the compressor fan. See the arrows on the compressor
belt guard. If the rotation is incorrect, do not use the power source until the phasing
has been modified by a certified electrical technician. After modification, recheck the
rotation.
1 Turn on the external power source (wall mounted switch).
2 Logon on the system via the HMI.
3 Select either operational mode: Automatic or Manual.
•
Automatic Mode - This is the recommended mode for on site operation when a
constant supply of compressed air is needed. In the mode, the unit automatically
restarts when system pressure drops about 6200psi below the maximum pressure.
•
Manual Mode - This mode is used for a single compression cycle. In this mode, the
unit brings the ASME storage cylinders up to maximum system pressure, but does
not automatically restart as the pressure is depleted. The unit must be restarted
when storage pressure has dropped below a usable level.
4 For normal operations, select Automatic.
The compressor ships from the factory with specific configurable parameters set to
defaults for normal operations.
5 During normal operations, the compressor monitors these specific parameters to
ensure proper operations. There are numerous items, and include: discharge
temperature, CO concentration, DP level, oil level, each stage pressure, and more.
Additionally the HMI provides helpful items for the operator that include: Alerts,
Information and Checklists. See “Using the Compressor HMI” on page 25.
6 Depending on the compressor model, continue to monitor the unit during
operations either using the HMI or the analog gauges, with special attention to
compressor pressure and storage pressure.
7 Ensure that the Air Flow that passes over both the DP and CO sensors are
adequate. This ensures that the sensors reading are accurate. This should be done,
when the system pressure for the 5th Stage reaches about 2500psi. To make an
adjustment, simply turn the Air Flow On/Off Knob as needed.
The compressor automatically activates a fifteen (15) second drain cycle at regular
intervals to remove moisture. However, a manual fifteen second drain cycle may be
activated at any time by pressing the drain button on the HMI. Sometimes, it is useful
to activate a Manual drain cycle to verify that the moisture separators are operating
properly. Once activated, check the HMI gauges to verify that they all drop pressure
and recover pressure simultaneously.
8 When the system reaches maximum pressure, the compressor runs a cool down
cycle for two (2) minutes. During this time, the compressor runs unloaded while
draining the moisture separators, and cooling down the compressor stages. After
087-0067 REV A
SCOTT SAFETY
Compressor Overview

the cool down cycle, the compressor stops. If the system is in the Automatic Mode,
the compressor restarts to refill the storage when the system pressure drops about
6200psi below the desired maximum pressure. In contract, if the system is in
Manual Mode, you must press Start on the HMI after the storage pressure drops
about 6200psi from full to restart the compressor to refill the storage.
9 When the compressor is in Automatic Mode, it restarts when the pressure drops
about 6200psi below maximum system pressure. If the storage pressure was
already full when the system started, the HMI displays Storage Full and the
compressor will still restart automatically when pressure drops.
10 Provided all compressor operating parameters are within tolerances, the system is
ready to fill breathing air cylinders.
Warning: Never attempt to perform service while the compressor system is in use in
the Automatic mode. When the compressor system is in the Automatic mode, the
compressor will restart when the storage pressure drops approximately 6200psi below
maximum pressure. This can happen at any time without warning. Failure to observe
this warning could result in serious injury or death.
Compressor E-Stop
Button
This section covers the compressor E-Stop button.
This is not the same as the HMI Stop, that provides an orderly compressor shutdown.
1 In case of an emergency, press E-Stop button. This automatically stops the
compressor. The compressor locks and is unavailable for four (4) minutes after the
Emergency Shutdown button is activated.
Warning: Use of the Emergency Shutdown button stops the compressor immediately
without the benefits of a two minute cool-down cycle. In the Emergency Shutdown
mode, the compressor is locked out and unavailable for four (4) minutes. Repeated use
of the Emergency Shutdown results in residual moisture in the system which may result
in serious damage to the equipment.

CHAPTER 4: OPERATION
Charge Station
Overview
This section covers an overview of the charge station.
We provide a full line of breathing air system components and related accessories for
the safe production and storage of compressed breathing air. Configurations of
breathing air systems will vary depending on selected options. Operators of these
units must become familiar with their particular system configuration and refer to the
proper operating instructions. These fill stations are intended only for charging
breathing air cylinders. The air compressor and purification system used with these
fill stations to fill breathing air cylinders must produce compressed air which meets
the requirements for Grade D or higher compressed air as specified in the Compressed
Gas Association publication CGA G-7.1 entitled Commodity Specification for Air,
available from the Compressed Gas Association, Inc., 1725 Jefferson Davis Hwy.,
Suite 1004, Arlington, VA 22202. In addition to meeting the requirements of Grade D
or higher, the air must be dry to a dew point of -65° F (-54° C) or less.
The fill station may be installed with storage cylinders or a manual or an automatic
cascade system. See “Automatic Cascade” on page 58. See “Breathing Air Cylinder
Inspection” on page 75. See “Storage Cylinder Inspection” on page 74. Read and
follow all safety labels on the unit.
Caution: Follow all recommended procedures and safety precautions as provided in
this manual. Federal, State and local codes mandate safety precautions and
procedures for the handling and production of breathable air. Consult State and local
occupational health and industrial safety ordinances for additional requirements.
Proper installation of the charge stations must be performed in accordance with Scott
Safety requirements, for optimum performance and adequate warranty coverage.
Maintenance and repair of the system must be performed by a Scott trained and
certified technician.
Automatic Cascade
The principle of a cascade air storage system is to make the most efficient use of the
air stored in multiple storage cylinders to fill breathing air cylinders. This is achieved
by always drawing air first from the storage cylinder with the lowest pressure and then
switching to the storage cylinder with the next highest pressure until the breathing air
cylinder has reached the target fill pressure. The comparison is made between the
storage and cylinder pressure. If the lowest storage pressure is higher than the cylinder
pressure then you start filling from that lowest storage until the pressure equalizes
with the cylinder pressure and you continue doing so until the last storage tank
pressure is equal to the cylinder pressure. If necessary, the fourth storage cylinder is
used to finally reach the target pressure in the breathing air cylinder. When the fourth
storage cylinder drops below the target pressure, no more breathing air cylinders can
be filled to the target pressure until the storage system is refilled by the compressor.
With an Auto Cascade system, pressure sensing valves automatically select the air
supply from each of the storage cylinders. The system opens and closes the storage
cylinders to efficiently use all the available air to fill the breathing air cylinders. The
operation of the Auto Cascade system does not require additional tasks or adjustments
by the operator.
087-0067 REV A
SCOTT SAFETY
Charge Station Overview
59
For systems with an integral compressor, the operator can choose to turn Off the
compressor after filling the storage and then fill the breathing air cylinders. The Auto
Cascade system will provide the maximum number of fills before turning the
compressor back On.
Charge Station
Interfaces
This section describes the different charge station interfaces. The operation of the
charge varies based on the model. The Scott models use a HMI to operate the charge
station. See “Configuration and Setup” on page 21. Other models do provide analog
gauges, but do not provide a touch pad controller.
Warning: When settings are changed, ensure those changes are communicated to all
affected personnel.
Depending on the configuration, the charge station may be controlled via the HMI. In
general, the HMI is used to start and stop the compressor and to provide information
about the compressors’ operation, performance and conditions to the operator.
Figure 30 shows an example of a charge station screen.
For more details, See “Configuration and Setup” on page 21.

This section cover charging the SCBA cylinders.
Using the charge station turntable chamber, two SCBAs may be charged simultaneous
while two more SCBAs are being mounted.
Caution: Before starting, check the inspect the SCBA cylinders. See “Breathing Air
Cylinder Inspection” on page 75.
Warning: When charging more than one breathing air cylinder together, charge only
cylinders that have the same pressure rating. Failure to follow this instruction can
result in cylinder failure and lead to equipment damage, serious personal injury, or
death.
Warning: If any air leak is noted, or the equipment does not operate as described in
this manual, immediately terminate use of the equipment and consult with a certified
service technician before proceeding. Use of malfunctioning equipment may create
circumstances resulting in serious personal injury or death.
Warning: When charging 75 minute 5500 PSI cylinders, there must be no cylinders
mounted on the outside of the charge station door. When charging any other size
cylinder, there must be no 75 minute 5500 PSI cylinders mounted on the outside of the
charge station door. Failure to obey these warnings may result in serious personal
injury or death.
Warning: Air pressure increases as temperature increases. When charging cylinders
in temperatures below freezing (32° F/0° C), frequently check air pressure and release
excess pressure as the cylinder warms to normal room temperature. Failure to do so
will cause cylinders to be in an overcharge condition, increasing the risk of cylinder
failure and leading to personal injury or death.
Fill Pressure
Adjustments
This section covers making fill pressure adjustments.
Caution: Never use a wrench or other tool to tighten the bleed valves or cylinder
adapters. Excessive force will damage the sealing surfaces and result in cylinder
leakage.
1 Check the pressure rating of the selected breathing air cylinder(s). See “Breathing
Air Cylinder Inspection” on page 75.
2 When charging more than one cylinder, verify that all cylinders are of the same
pressure rating. If they are different, sort them by their rating, and only charge
cylinders together that have the same rating. Never mix ratings.
Warning: Never mix ratings. When charging more than one breathing air cylinder
together, charge only those cylinders that have the same pressure rating. Failure to
follow this instruction can result in failure of the cylinder or cylinder valve, and can
lead to equipment damage, serious personal injury, or death.
3 Verify that the compressor or storage pressure is greater than the fill pressure of the
selected breathing air cylinder. If pressure is too low, allow the compressor system
to continue building pressure. See Figure 34 and Table 24.

Never leave an unused charge adapter open. When charging only one cylinder, verify
that the cap is secure on the unused adapter.
4 Open the breathing air cylinder valves located on the top of the mounted cylinders.
Warning: Always open cylinder valves slowly. Careless handling of compressed air
can cause pressurized air to release suddenly, which can result in serious injury or
death.
5 Open the charging chamber door lock by operating the handle on the right side of

7 Close and lock the charging chamber door handle. The door is locked when the
Yellow lock bars are visible around the door frame.
8 Open the Manual Air Flow On/Off Knob 1/8 to 1/2 turn counterclockwise to begin
filling the cylinders.
9 Consult the cylinder manufacturer and the appropriate government regulatory
agency for fill rate recommendations. Do not exceed the fill rate recommendations
for the breathing air cylinders being filled.
Warning: Do not exceed the recommended fill rate for the breathing air cylinders.
Failure to follow this warning may result in catastrophic failure of the cylinder,
leading to serious personal injury or death.
10 Adjust the fill rate as follows:
a Slowly turn the Manual Air Flow On/Off Knob counterclockwise to increase
the rate at which the cylinders are filled.
b Watch the pressure reading on the breathing air SCBA Cylinder Pressure
Gauge.
c If the fill rate is too high, turn the Manual Air Flow On/Off Knob fully
clockwise to decrease the flow, then slowly turn the Manual Air Flow On/Off
Knob counterclockwise to adjust to the proper rate.
d Once fill pressure and fill rate are set for charging cylinders of the same
pressure rating, minor readjustment may be necessary as the storage and
compressor pressures will vary during multiple breathing air cylinder fills.
11 Leave the fill pressure and fill rate set when charging several cylinders that require
the same fill pressure and fill rate. Minor adjustments may be necessary during
filling of successive cylinders depending on the compressor system used.

12 While the breathing air cylinders are being filled inside the charge chamber, mount
the second set of cylinders on the rigid adapters on the outside of the charge
chamber. Be sure to hand-tighten the bleed valve and to open the breathing air
cylinder valve(s).
13 When the breathing air SCBA Cylinder Pressure Gauge reaches the pre-set charge
pressure, open the chamber lock by operating the handle so that the Yellow lock
bars are not showing. This will automatically stop the cylinder charging process.
Warning: If any air leak is noted, or the equipment does not operate as described in
this manual, immediately terminate use of the equipment and consult with a certified
service technician before proceeding. Use of malfunctioning equipment may create
circumstances resulting in serious personal injury or death.
14 To access the breathing air cylinders, verify that the chamber lock handle is in the
unlocked position so that the Yellow lock bars are not showing around the chamber
door. Rotate the chamber door 180° until it clicks into position.
15 Close the cylinder valves on the mounted breathing air cylinders.
16 Slowly open the bleed valve just enough to vent the air lines to the cylinders. Vent
until all air flow stops. If the air does not stop venting, verify that the cylinder
valves are closed.
17 Hold the cylinder in place and turn the charge adapter clockwise to remove the
cylinder. Handle the charged cylinder carefully.
18 Replace the charge adapter plugs.
High pressure charging causes a rise in cylinder temperature. As the cylinder cools,
the pressure gauge will show a decrease in pressure. This is normal. After cooling,
cylinders may be placed back in the fill station and “topped off” to full pressure.
Warning: Air pressure increases as temperature increases. When charging cylinders
in temperatures below freezing (32° F/0° C), frequently check air pressure and release
excess pressure as the cylinder warms to normal room temperature. Failure to do so
will cause cylinders to be in an overcharge condition, increasing the risk of cylinder
failure and leading to personal injury or death.

CHAPTER 4: OPERATION
Storage Overview
The compressor may be configured to direct compressed and purified breathing air to
an optional air storage unit. Storage units may meet peak demands for compressed air
without requiring of a full time operation of a compressor. Stored air may be used to
carry on operations if a compressor fails, loses power or when air is needed when a
compressor is not available. All storage units are equipped with service values and
safety relief gauges.
•
Storage cylinders - ASME cylinders do not require hydrostatic testing, but include
a drain valve and gauge. If installed, safety valves on ASME cylinders must be
tested on an annual basis. ASME safety valves can be identified by a tag or label
showing traceability to the National Bureau of Standards (NB) and a tamper
evident seal. Some Scott storage systems with ASME storage cylinders are
protected by single use rupture disks that cannot be tested. Each ASME cylinder
has the capacity to store 454 standard cubic feet (SCF) at 5K PSI, or 525 SCF at
6K PSI. Refer to specific ASME safety standards for additional testing
information.
•
Storage configuration - Storage receivers can be configured together as a single
bulk storage bank (Bulk Storage), or separately in a cascade system (Automatic
Cascade). When configured as a single bank, cylinders are “piped” together into a
single volume. Storage pressure is indicated by a single gauge on the main control
panel or on the HMI, depending on the model. Cylinders in a cascade system are
plumbed separately which allows for more efficient use of compressed air since
each cylinder can be isolated when accessing system air.
The fill station may be installed with storage cylinders or a manual or an automatic
cascade system. See “Automatic Cascade” on page 58. See “Storage Cylinder
Inspection” on page 74. Read and follow all safety labels on the unit.

pressure. Compressed air will automatically be directed to the storage cylinders.
•
Monitor the storage pressure, indicated by either gauges or HMI, depending on the
model. Also, indicators will be based on the configured storage volume method of
the receivers: bulk volume, or cascade volume.
The time required for charging the air storage system depends on the number and
pressure rating of the storage cylinders. If cylinder pressure does not build properly,
contact a Scott certified service technician to troubleshoot the system.
SCOTT SAFETY

CHAPTER 4: OPERATION
The Cascade configuration, depending on the model, includes individual gauges on
the control panel or on the HMI, and control valves for monitoring and controlling the
flow of compressed air in each cylinder. Each cylinder may be isolated, or “shut off”
to prevent compressed air from entering or exiting the cylinder. To isolate a cascaded
cylinder, simply turn the control valve clockwise to shut off the air flow. Turn the
valve counterclockwise to allow the compressed air to flow as normal.
