1 Safety Precautions
Read through this manual carefully before use and use the PHE properly as indicated.
If you have any questions, please inquire with our company.
Precautions are categorized using the following symbols.
WARNING
This symbol indicates content where mishandling could result in death or severe injury.
CAUTION
This symbol indicates content where mishandling could result in injury or property damage.
NOTE This symbol indicates important matters and/or useful information.
 Meanings of Symbols
Indicates items that are
"prohibited (something that you must NOT do)".
Indicates items that are
"mandatory (something that you must do)".
WARNING
Do NOT loosen PHE's tightening bolts/nuts except for maintenance work.
The PHE could come apart if tightening bolts/nuts are loosened before installation.
Do NOT use tightening bolts with loosened bolt heads.
If the bolt head loosens and the bolt head (nut) comes off the bolt, it could fly off at high
speed. This is dangerous and contact could cause serious injury or property damage.
Do NOT use a flange gasket for the nozzle of heat exchangers with synthetic
rubber covering.
Sealing performance could be decreased and it could be a cause of leaking.
(Flange gaskets are required for nozzles with metal covering.)
Do NOT incinerate gaskets.
Incinerating gaskets releases a toxic gas and is very dangerous.
Any unnecessary gaskets should be disposed as industrial waste in accordance
with international, national, prefectural, and municipal regulations.
For the industrial waste treatment company, use a company that has received
permission from the prefectural governor.
In general, do NOT perform pneumatic test for medium and large size PHE.
For small size PHE, do NOT perform pneumatic test at the same pressure as
hydrostatic test pressure.
If a leak occurs during a pneumatic test using compressed air or nitrogen, it is extremely
dangerous as, in addition to the test pressure, volume expansion causes an impact.
In general, do NOT perform a pneumatic test in excess of 0.75 MPaG.
Install a protective cover on heat exchangers that handle high temperatures,
high pressure, or dangerous fluids such as strong acids or strong alkalies.
If a dangerous fluid leaks, it could cause a serious accident.
Make sure that the operation is stopped, the internal pressure is "0", and the
fluid temperature has sufficiently dropped before disassembling the PHE.
If a fluid sprays out from the heat exchanger interior during disassembly, it could
cause burns or lacerations.
Do NOT operate in excess of the design conditions
(temperature, flow rate, pressure, etc.).
It may cause deformation of the heat transfer plates or leakage. Also, the required
performance may not be achieved.
Do NOT loosen the thermometer, pressure gauge, tightening bolts and nuts, or
any other accessories during operation and when the PHE are pressurized.
If fluid splashes from the PHE during disassembly, it may cause burns or lacerations.
Perform gasket replacement in a well-ventilated area or area with ventilation
equipment.
The gasket dedicated adhesives "S-1" and "F-2" contain organic solvents. Breathing
the volatile ingredients for a long time may cause symptoms such as headache,
dizziness, and nausea. Should these symptoms occur, move somewhere with fresh
air and rest, stay calm and warm, and seek medical attention.
Do NOT use tightening bolts with damage such as significant rust or cracks.
If a tightening bolt breaks during operation or during disassembly, not only will the
fragments fly off, but there is also danger of the fluid in the heat exchanger interior
spraying out.
CAUTION
Do NOT touch the side of the heat exchanger element (edge of the heat
transfer plates).
The edge of a heat transfer plate is very sharp and may cut you.
Be sure to wear cut-resistant gloves whenever touching the heat transfer plates.
Request an expert to perform piping work, and review the assembly drawings
with them beforehand to ensure that connections are properly made.
Work performed by inexperienced personnel can result in a faulty or improper
connection. An improper connection can result in failure to provide the specified
performance or an equipment malfunction.
Do NOT place objects on the heat exchanger.
Doing so may cause deformation of heat transfer plate or a falling object may
cause injury during operation.
Do NOT touch anything the side of the heat exchanger element (edge of the
heat transfer plates).
Deformation of the heat transfer plate may cause damage to the plate gasket and
result in leakage.
Secure working space around the PHE.
Installation and piping design must take into account the working space required
for using disassembly and installation tools.
In general, do NOT remove the stud bolts on the heat exchanger nozzles.
Removing the stud bolts may cause damage on the threads.
If it is absolutely necessary to remove them, remove them carefully so as not to
damage the screw threading on the stud bolt and the frame. Also, stud bolt removal
shall be done at the customer's liability.
Clean the piping interior before connecting.
Clean piping thoroughly so that no debris enters the PHE.
Select flange gasket material that is suitable for the fluid specifications.
Flange gaskets are required for tube flange and metal boot types.
Do NOT weld or attach any piping support to the frame, guide bar, or guide
bar support.
Such welding may cause thermal damage to gaskets, or the attached part may
cause interference that prevents parts from fulfilling their function. Furthermore, the
installed part will be an obstacle and will prevent disassembly.
Install sufficient support for piping connected to the PHE.
A large piping load to the PHE may cause the frame to become deformed or
leakage.
Do NOT allow debris or foreign material to get inside the PHE.
The clearance of the PHE is quite narrow, such that it can be easily clogged by
debris or foreign material. When flushing the piping, take measures such as
installing a temporary strainer at the inlet piping or bypassing the PHE in order to
prevent debris or foreign materials from entering the PHE.
Perform maintenance of PHE that handle dangerous fluids, such as a strong
acids or alkalies, in an environment that has wastewater treatment equipment.
Process waste fluid in accordance with the law and regulations. Be careful not to drain
liquid into a river or ocean area. If untreated liquid leaks, take measures in accordance
with the "Material Safety Data Sheet (MSDS)" for the treatment liquid you used.
Do NOT allow the fluid to freeze.
In cold areas, remove the fluid inside the heat exchanger and empty the equipment
before storing it.

2 “Slit-in” Plates and Gaskets
 “Slit-in” plates are indicated by the letter "A" at the end of the model number indication. (Examples: UX-016A and UX-216A)
 “Slit-in” plates have slits (holes) that are used for fixing gaskets to the plate.
 These slits (holes) are located on the outside of the plate gasket groove and in the port holes (excluding UX-005A and
UX-01A).
 “Slit-in” gaskets are indicated by the letter "A" in front of the material indication. (Examples: A-NBR and A-EPDM)
 “Slit-in” gaskets have protrusions for fixing the gasket to a plate.
 Handle gaskets with care because a protrusion can be cut easily.
3 “Slit-in” Gasketting Procedures
 There are four type of protrusions depending on each PHE model (Fig.1).
