• The Air Knocker is designed to prevent materials from adhering to or blocking flow in process
equipment by using forced air. Do not use the Air Knocker for any other purpose.
• Care has been taken to ensure the safety of the Knocker. Be sure to read this instruction
manual and note the warning and caution messages before using the Knocker.
• The following symbols represent warning and caution messages to be observed when using
the Knocker to prevent injury or damages to users or other persons.
Refers to a hazard that may cause death or serious injury.
Refers to a hazard that may cause slight or medium injury.
WARNING
TO PREVENT DEATH:
• After installing the Knocker, make sure to attach the fall prevention wire to it to
prevent it from falling due to percussion during operation.
• In the event that the Knocker falls, be sure to replace the fall prevention wire even if
it appears to be undamaged.
• Do not connect the electric control devices (Knocker control board or three-way
solenoid valve) for the Knocker to a power source which is not equipped with a
breaker for preventing electric shock.
CAUTION
TO PREVENT INJURY OR DAMAGES:
• When removing the piping tube, please be sure to close the air supply from the
control equipment and to release the air pressure which remains in the Knocker. If
the tube is removed while air pressure still remains, the Knocker will operate, and
there is a possibility of an unexpected injury.
• Securely weld Knocker base to the vessel so that the Knocker does not fall due to
percussion during operation.
• If the vessel metal thickness is too thin, weld a reinforcing plate onto it to prevent
the mount plate from being damaged as a result of impact during operations.
WARNING
CAUTION
Safety Precautions
• Be sure to read this instruction manual carefully before using the Knocker.
• Handle the Knocker appropriately and inspect it to maintain its performance.
• Keep this manual for future reference.

Safety
CAUTION
FOR PERSONAL PROTECTION DURING OPERATION:
• Put on a safety helmet, safety boots, safety gloves and a safety belt, before any
installation work is started.
• Conduct all required lock-out, tag-out or similar required procedures prior to inspection
or repair.
• When using the fall prevention wire to prevent Knocker from falling, be sure to secure
shackle with appropriate tie to prevent shackle screw from loosening from percussion
during operation.
CAUTION
FOR LONGER SERVICE LIFE:
• When installing the air line, include a filter or filter/regulator prior to the Solenoid
valve to minimize dust getting into the Solenoid valve, which may inhibit the Knocker
from operating properly.
• Make sure the force of impact does not exceed the maximum level, as excessive
impact may damage the vessel it is mounted on.
• When applying continuous impact at short cycles, allow an interval of at least one
second. An interval of less than one second may lead to damage or operation
problems.
• Only start air lines after checking that there is no foreign substance, chips, or slag
on the piping materials.
• Flush with the air pressure of 44 psi or more, to clean any debris or contamination
in the piping.
• Use air that passed through an air filter 5 micrometers or less. Moisture or dust in
line will potentially cause poor operation and air leakage.
• The line should connect to the IN side in the direction of the flow and to the IN port
displayed on the product.
• Do not use in an area with corrosive explosive gas.
• When using a sealant, be careful to keep from inside the line, and seal to prevent
external leaks. When wrapping sealing tape around the screw part, wrap the tip of
the screws leaving 2 to 3 threads. Also, when using a liquid sealant, coat leaving 2
to 3 threads. Do not coat the female screws of the equipment. Tighten and check
for air leaks.
• In cold areas, please protect against freezing. (Air should not freeze)
• Avoid placing a heavy load on the lines.
• Operation air should contain some moisture or light oil. Operating using dry air may
shorten the product’s life cycle.

2. WELDING THE REINFORCING PLATE:
• If the vessel wall thickness is too thin, weld a reinforcing plate onto it. Welding procedure should use
all-around welding so that no gap arises between the vessel and the reinforcing plate. Leave one spot
unwelded for bleeding air. If no spot is left unwelded for bleeding the air, the air creates a cushion,
dampening the effect of impact.
• A large impact force is transferred to the reinforcing plate at the time of operation. In order to avoid
failure, install as instructed.

Piping
• Select either standard or relay system piping per the examples below.
• When only one system is used with the control board (HKA and EKE models), place a
blind stopper in the unused system.
• In the control board (HKA and EKE models), the Knocker can be connected to line A or
line B, but note that the pressure accumulation and percussion operations are reversed
on one system.

2. TUBE LENGTH IN STANDARD PIPING
• Make air lines as short as possible to maximize the impact force.
• The maximum length of a piping tube changes with model, air pressure,
and control unit, and may decrease Knocker effectiveness by 10 to 20%.
• When adding another pipe, the length of the tube from the branch point to each Knocker
should be equal.
• Avoid extreme bending and adding extra lines. It may affect operation and impact force
especially in units furthest from the air supply.
• It is recommended to set the minimum tube pressure at 44 psi to maintain stable
performance. Impact force can be maintained by increasing air pressure.
• When arranging the piping between the Knocker and the control devices, use nylon or
urethane tube which has a OD of 5/16 in.

3. EXAMPLE IN RELAY SYSTEM PIPING: D/E/F
• Relay system piping method that connects two or
more Knockers in series. This method is connecting
a relay tube from air tank of the Knocker (cross
valve side) to air supply and exhaust opening of
another Knocker.
• When using relay system piping, Knocking action
starts in order from a Knocker that is located
in cross valve side to other Knockers. The
maximum number of Knocker that can be used
is regulated by the type of control.
• When arranging relay piping, please set the
actuation of the solenoid valve at 1 second or more. When the tube length of relay piping becomes
long and/or the number of relay pipes increase, please extend actuation of the solenoid valve.

4. TUBE LENGTH OF RELAY SYSTEM PIPING AND AIR PRESSURE
• In relay system piping, compressed air in the relay tube is also used for operation air of the Knocker.
Accordingly, the air pressure is not to exceed the regulated valve. (Refer to length of relay tube in
relay system piping and air pressure)
• Use 5/16 OD nylon or urethane tube when arrange piping between Knockers and control
equipment. (Please use 1/4 OD tube for KNR-20.)
• Arrange tube length to the first Knocker as referenced in standard piping, section 2.
• It is recommended to connect a piece of dummy tube (that is same length as the relay tube) to the
terminal Knocker, so the knocking force of every Knocker is equal. (Refer to Section 3. Example of
relay system piping - pg. 13)
• In order to prevent an air leak, please equip the end of the dummy tube with a cap.
• In relay system piping, the knocking force increases when the tube length is extended but it will effect
the durability of the Knocker unit.
• Length of connecting tube (relay tube) for 2nd and other Knockers are dependent on the type of
Knocker. Length between is not to exceed the maximum length. Also, make the length as even as
possible to balance knocking force. (Refer to table)
Knocking force at value listed above is equivalent to the knocking force at maximum air
pressure (102 psi) in standard piping

Test Operation and
Settings Before Use
After mounting and piping the Knocker, run a test operation and complete the settings in
accordance with the following procedure:
1. Set the air pressure to 44 psi. (14.5 psi at relay piping)
2. Set the most suitable air pressure in the regulated range by increasing the air pressure
of the regulator 5 psi apiece.
Note: The farther the Knocker is from the regulator, the lower the pressure at the Knocker compared to the
pressure indicated at the regulator. In such a configuration, set the pressure slightly higher.
Inspection
Inspect the following items at least once every three months to minimize trouble during operation:
1. Are any nuts or bolts loose?
2. Are any welded parts cracked?
3. Have any contaminants gotten into the Knocker?
4. Is there any abnormal wear on the cylinders or pistons?
5. Is there any spring damage?
6. Is there any damage to safety wire assembly?
