１．Precautions for use
Please be sure to observe the precautions for using the high blow nozzle.
① When using the high blow nozzle, be sure to fully understand the performance of the blower and hot air
generator, and use each method with due consideration.
② Never let any fluid other than air, steam, or water (only liquid type available) pass through this product.

③ This product is an aluminum product. Handle it with care, as it may be damaged or deformed if shocked. In particular, thetip of the slit has an acute angle, so be careful not to drop it during transportation or mounting.

④ When discharging hot air, be sure to fully understand the surrounding environment and take measures againstburns and environmental measures by installing a heat insulating cover.
⑤ The heat resistant temperature of this product is approximately 250°C or less. If it is used at a temperature
higher than that, deformation due to heat and air leakage will occur.

⑥ The maximum efficient air supply is determined by the model of this product, the number of air supply ports, and the slit
area (see catalog). If it is used outside this range, the left and right wind speeds may fluctuate, and uniform air is notdischarged, resulting in poor performance. Be sure to use within the effective maximum supply air volume.

⑦ The maximum withstand pressure of this product is 2 kgf/cm2 or less. If you use it with a pressure higher than this, there
is a risk of explosion, etc., so please strictly observe the maximum withstand pressure.

⑧ This product is an aluminum product, so never flow a fluid containing corrosiveness.
⑨ Packing is used for the joint of this product. It may be deteriorated by heat, so be sure to check it regularly.

Please refer to the following as an effective installation method of the highblow nozzle when draining and drying with hot air.
① Install at an angle of 5° to 15° with respect to the direction in which
the object is being conveyed.
② Make the distance between the high blow nozzle and the targetas close as possible.

２．EFFICIENT USE

３．HOW TO FIX
The high blow nozzle with a slit length of 401 mm or more is equipped with a fixture as standard (400 mm or less is an option). Since the fixing
metal fittings differ depending on the shape of the nozzle supply port, fix it with the method that matches the shape of the supply port.

① Use either the upper fixing bracket or the lower fixing bracket (standard equipment for slit lengths of 401 mm or more).
Also, when changing the blowout angle for the S1 type (1 port on the side), maintain the blowout angle with steel pipe
piping that uses the screw part of the air supply port, instead of holding only the tip fixing bracket. In addition, since thetip fixing bracket cannot be attached to the S2 type (2 ports on the side), be sure to maintain the blowing angle withsteel pipe piping that uses the threads on the air supply ports on both sides.

Be sure to secure a sufficient clearance between the air discharged from the nozzle
and the furnace (Fig. 1).Especially when the discharge wall is close to the furnace wall,
the amount of air entrained around the furnace wallis small, and air flows to the furnace wall side that is close to the furnace wall,and the straight advanceof discharge air is not maintained (Fig. 2). ..

deformed.
③ This product is an aluminum product. When screwing the main body into steel pipes, do not hang a pipe
wrench on the main body and tighten it properly to secure it firmly.
④ When fixing the high blow nozzle, consider the weight of the high blow nozzle and do not drop it due tovibration.
⑤ When using hot air through the nozzle, the fixing bracket also becomes hot, so take sufficient measures toprevent heat from the fixed part and the surrounding area. The high blow nozzle itself also expands thermally,so make sure to consider the length of expansion and install it with a gap (see table below).

⑥ When installing the high blow nozzle, make sure that it does not come into contact with the target work. If awork such as an iron plate collides, the slit part of the high blow nozzle will be damaged. Also, when hot air isdischarged, the surface of the high blow nozzle also becomes hot, which may cause a fire if flammableworkpieces come into contact with it.

４．PIPING
The air supply port of the high blow nozzle is an external screw (nipple) of 15A, 25A, 40A, 50A. Use the same size
inner screw (socket) for piping. In addition, flexible hose piping can be supported by using the optional hoseconnection socket.
① Tighten the connections securely and make sure there are no air leaks.
② To prevent the weight of the connected steel pipes from being applied to the high blow nozzle and the fixing
bracket, hold the steel pipes firmly with other fixing methods. If a load is applied to the high blow nozzle, it
may cause damage or deformation.
③ When piping through hot air, the piping becomes hot, so take sufficient consideration of the surrounding
environment and take measures against burns and environmental measures such as heat insulation
construction and cover installation. Also, be careful not to affect the high blow nozzle as the steel pipes that
supply hot air will also expand thermally.
④ When using a flexible hose for piping, consider the pressure of the air source and select a flexible hose with
sufficient pressure resistance. Especially when using a high-pressure blower (such as a vortex blower), inaddition to the pressure, the temperature may rise due to the heat of compression.

５．HOW TO ADJUST THE SLITThe slit width of the high blow nozzle can be changed by adjusting the tip slit.

Note: If the maximum slit area is adjusted beyond the table above, the left and right wind speed will vary.
《caution》
1. Depending on the performance of the blower, adjusting the slit to increase the discharge air speed may
reduce the air volume and discharge air speed. Please refer to the performance curve in the catalog andadjust within the capacity range of the blower.
2. When loosening the screws, be careful not to let each part come off and fall.
3. Packing is attached to the tip cap and inlet cap. Be careful not to damage the packing when making
adjustments. Damaged packing may cause air leakage.
4. After adjustment, securely tighten each loosened screw.

６．How to clean up
By disassembling the high blow nozzle, you can clean the dust and dirt accumulated inside.
① When cleaning, remove the Hi-Blow nozzle from the fixed location before performing cleaning. At this time, becareful not to drop the high blow nozzle.
② When cleaning, remove each screw of the high blow nozzle and disassemble it. Also, pull out the innerrectifier grid slowly.
③ Clean each disassembled part with a soft brush. If the product has been washed with water, wipe it off with acloth, etc. and dry it completely before reassembling.

※ When hot air is supplied to the high blow nozzle, symptoms similar to cracks may be seen on the surface of thehigh blow nozzle, but this is due to the difference in expansion coefficient between the anodic oxide coating
applied on the surface and the aluminum alloy material. Fine cracks can be visually confirmed, and there is noproblem with the performance of the high blow nozzle.

７．High blow nozzle liquid specifications precautions
The high blow nozzle liquid specification (ordered product) can discharge liquid such as water.
① The high blow nozzle liquid specification has an alumite treatment on the inner surface, but consider thecorrosiveness of the main body when supplying the liquid.
② The maximum withstand pressure of this product is 2 kgf/cm2 or less. If you use it with a pressure higher
than this, there is a risk of explosion, etc., so please strictly observe the maximum withstand pressure.

③ Make sure that the piping does not leak. Also, when connecting with a PVC pipe, a potential difference will occur due tothe flow of water and pinholes etc. will occur due to electrolytic corrosion, so be sure to perform ground wiring.

When discharging a liquid containing a large amount of chemical components, corrosion or electrolytic④ corrosion (generation of pinholes) may occur suddenly. Therefore, when using such a liquid, consider the highblow nozzle as a consumable item.
⑤ With the high blow nozzle liquid specification, the chamber and slit are bonded, so the slit width cannot beadjusted or disassembled. If it is disassembled, the packing cannot be used and water leakage will occur even
if it is reassembled.

８．Precautions for suction nozzle
The suction nozzle (ordered product) can suck in water, dust, dust, etc. that have been blown and scattered in
the atmosphere. Also, by collecting hot air, it can be used for environmental measures.

① If you want to inhale water, dust, dust, etc., please prepare a dedicated blower (water-resistant type, dust-proof type, etc.).
② We recommend installing a filter at the inlet of the blower for suction.
③ If you want to suck in dust and dirt with the suction nozzle, clean the inside of the nozzle regularly.
