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 use a piping gasket to the rubber covering nozzle of PHE.
Sealing performance could be decreased and it could be a cause of
leaking. In case of metal covering nozzle, piping gasket is required.
Keep fire-fighting equipment when handling flammable media.
If the flammable media ignites during operation or maintenance, it can
lead to a major accident.
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.
When compressed air or nitrogen for pneumatic test is leaked, it is very
dangerous since there would be an impact caused by volume expansion
in addition to such test pressure.
In general, do NOT perform pneumatic test in excess of 0.75 MPaG.
Install a protective cover on PHE when handling dangerous media,
which is high temperature, high pressure, strong acid, or a strong
alkaline.
If a dangerous media leaks and is splashed, it may lead to a serious
accident.
Do NOT loosen the thermometer, pressure gauge, tightening bolts
and nuts, and/or any other accessories during operation and/or
PHE pressurized.
It may cause burns or injury if fluid is blown out from PHE/pipes.
Make sure that the operation is stopped, the internal pressure is
"0", and the fluid temperature has sufficiently dropped before
disassembling the PHE
If fluid splashes from the PHE during disassembly, it may cause burns or
lacerations.
Do NOT use damaged tightening bolts, such as improper rust or
cracks.
When the tightening bolts breaks during operation or disassembly, it is
dangerous not only broken pieces are scattered, but also fluid may
splash from PHE.
When removing gasket, carry out in proper location with good
ventilation.
The gasket should be adhered with Hisaka’s “S-1", "F-2" contains an
organic solvent. Breathing the volatile ingredients for a long time may
cause symptoms such as headache, dizziness, and nausea. If these
symptoms occur, remove person to fresh air. If signs/symptoms develop,
get medical attention.
Do NOT use tightening bolts with loosed bolt head.
If the swaged bolt head loosens and comes off the bolt, it could burst at
high speed. It may cause a serious accident for any person or property.
Wear protective equipment such as protective goggles, a mask,
rubber gloves, and protective clothing if handling a dangerous
fluid such as a strong acid or strong alkaline.
Eye Contact: Flush eyes with large amounts of water. If signs/symptoms
persist, get medical attention.
Skin Contact: Remove contaminated clothing and shoes. Immediately
flush skin with large amounts of water. Get medical
attention. Wash contaminated clothing and clean shoes before reuse.
Inhalation: Remove person to fresh air. If signs/symptoms develop, get
medical attention.
If Swallowed: Do not induce vomiting unless instructed to do so by
medical personnel. Give victim two glasses of water. Never
give anything by mouth to an unconscious person. Get medical
attention.
Do NOT incinerate the gasket.
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.
Also, gaskets should be disposed under the local jurisdiction.
Do NOT handle the heat transfer plates in any place with strong
wind.
Under strong wind, the heat transfer plates it could fly, cut, injury, and
bruise.

P2
CAUTION
Do NOT touch the side of plate pack and heat transfer plate edge.
The edge of a heat transfer plate is very sharp and may cut you.
Be sure to wear cut-resistant gloves whenever touching heat transfer
plate.
Do NOT freeze.
If freezing occurs in PHE, the heat transfer plates may be damaged.
Drain out completely to avoid freezing in case of preservation in cold
areas. In warm areas, if storing the equipment for a long time, store it
with liquid at full capacity.
Do NOT place objects on plate pack.
It may cause deformation of heat transfer plate.
Falling object may cause injury during operation.
If using a pump with specifications in excess of the PHE's design
pressure, install a safety device on the pump's delivery side or the
PHE's inlet or outlet.
Even if not required by applicable code and regulation, a safety device is
necessary to protect the equipment.
Do NOT make heat transfer plate edge deform by contacting with
surrounding object.
Deformation of the heat transfer plate may cause damage on plate
gasket and result in leakage.
Secure working space around PHE.
Adequate piping design is required, taking into account the working
space for disassembly and tightening device.
Do NOT shorten guide bar by cutting.
It makes disassembling of the PHE impossible. Perform maintenance of PHE that handle dangerous fluids, such as a strong acid or strong alkaline, in an environment that has drain
water treatment equipment.
Waste media in accordance with laws, codes 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.
In general, do NOT remove stud bolt of connection.
It may cause damage on the threads.
Stud bolt is to be removed very carefully not to make any damage on the
threads of both stud bolt and its hole at your own risk, only when it is
absolutely necessary.
Do NOT weld or attach any piping support onto the frame, guide
bar, and/or guide bar support.
Welding causes thermal damage on plate gaskets and attached parts
may interrupt handling when disassembling.
In case of inner strainer is inserted PHE, remove it at the time of the
back wash.
It may cause damage on the inner strainer.
Do NOT enter debris or foreign materials into PHE.
Install a strainer on upstream to prevent clogging in PHE.
When flushing pipes for commissioning operation, install a temporary
strainer or provide bypass on upstream PHE in order to prevent debris
or foreign materials into PHE.
Remove the smell of gaskets and/or adhesive by hot water cleaning
inner of PHE in order to prevent the fluid from absorbing these
smells.
Fluid may absorb the smell of plate gaskets and/or adhesive when
PHE is newly installed or plate gaskets are replaced.
To avoid above, clean the inner of PHE using hot water and remove the
smell. In case of applying F-2 adhesive for food product use, cleaning
with 80℃hot water and 8 hours is recommended as a minimum.
Do NOT start and stop the pump frequently (in a short time).
During commissioning, pay attention to time duration of pump start/stop,
or there would be leakage due to difficulty of gasket restoration caused
by temperature and pressure variation. After stopping, min. 3 minutes is
recommended to restart.
Open and close the valve slowly so as not to create a sudden pressure
fluctuation.
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 apply impact pressure and instantaneous pressure
fluctuation.
Do not apply impact pressure and instantaneous pressure fluctuation to
PHE, such as from starting-up of pump, sudden close of valve, or by
steam hammer occurred. Deformation, cracks, or leaks in the heat
transfer plates are possible if long time repeated pressure pulsation
within few seconds
Do NOT apply instantaneous negative pressure.
Drawdown may occur if instantaneous negative pressure is applied to
the PHE by pump stop or valve closing, or heat transfer plates
deformation may also.

8 Tests Before Commissioning Operation
After installation, commissioning operation of the PHE is to follow the conditions below.
Check the following nine items.
If all of the items are not satisfied, do not operate the equipment and inform your supervisor or safety manager.
Install safety apparatus compliant with various standards or regulations to the PHE installed line.
Confirm that the nozzle orientation in the "Plate Arrangement Drawing" and "Assembly Drawing".
Provide venting on both side of the PHE to facilitate the removal of air from the system.
Do not apply valve and piping loads to the nozzles. Use pipe supports not to load on the S-, C-, and E-Frames.
However, support structures are not installed in the maintenance space, or a removable support structure is used.
Ensure that flushing is completed in order to prevent welding spatter, debris and/or foreign materials into PHE.
Confirm that the tightening length is correct.
Tightening length on the Assembly Drawing may differ from actual length. Refer the tightening length in the nameplate which
describes the actual dimension at the delivery and after maintenance.
Confirm that all nuts for tightening bolt are not loose. Confirm that all nuts for S-,E-nozzle are not loose.
Fulfill the fluid for both hot and cold side. Confirm all air is out and liquid will flow out of the vent. Ensure that start the
operation with fulfilled condition, when non-fulfilled condition of PHE, it may result the following;
- pump overload
- heat transfer plates may be deformed and cracked, leaked due to impact pressure
There is no leak between the heat transfer plates, piping connections, or other locations.
PHE has been performed pressure-leak test before delivery. In case of retest at site, follow below instructions.
Also, in case of pressure /leak test for whole system including up/down stream equipment, follow below instructions.
In case of hydrostatic test
Pressurize hot and cold side independently and/or both sides at the same time. Actual test pressure shall not exceed the
specified test pressure. Over test pressure could result in heat transfer plate/frame deformation and/or leaking. The test
pressure is referred to Plate Arrangement Drawing.
In case of pneumatic test
Pressurize hot and cold side independently and/or both sides at the same time. Keep distance from PHE during the test.
When compressed air or nitrogen for pneumatic test is leaked, it is very dangerous since there would be an impact caused
by volume expansion in addition to such test pressure. The test pressure is referred to Plate Arrangement Drawing.
Initial flushing for piping shall be performed after piping before operation in order to prevent welding slag and/or leavings, such
as tool or dust cloth, come into PHE chamber. Generally, the methods of flushing are;
- Removing PHE from the piping
- Applying the temporary strainer for the upstream piping
In case of removing PHE from the piping, do not remove studded bolt on PHE frame. In case of applying temporary straighter,
refer to “1 Installation Manual, Table 8-1 Recommended strainer hole size” and select the adequate strainer hole size. Apply the
strainer with external reinforcement such as punching metal because screen without reinforcement can be damaged easily.

12-3-2 Replacement of Plate Gasket
Replace a plate gasket if it has any wearing, cracks, swelling, carbonization, adhesion, or foaming.
For types of plate gaskets, refer to each model's "Gasketting Manual".
(1) Removing the plate gasket
1) Remove the used gasket.
Remove the used gasket with moderate force not to deform the heat transfer plate.
At this time, be careful not to damage the heat transfer plate.
2) Clean the plate gasket groove of heat transfer plate.
Use solvent on the market to wipe away any adhesive remaining in the heat transfer plate's gasket groove.
Remove dirt, dust, which is stuck on the heat transfer plate's gasket groove.
(2) Preparing to replace the plate gasket
1) If replacing plate gaskets, check and prepare the number of required gasket.
Visually check that there is no dirt, dust, which is stuck on the plate gasket's front and back surfaces. If there is
any visible scale on the front or back surface of the plate gasket, wipe it off using a clean dust cloth.
2) Prepare appropriate adhesive for the plate gasket material.
There are the following four types of adhesive. Use the adhesive HISAKA specified.
Types of adhesive Purpose of use
S-1 General use
F-2 For food products
Silicon type For silicon gaskets
Double-sided tape PTFE encapsulated gaskets, etc.
(3) Gasket adhesion.....Glued gaskets
1) Applying adhesive
Uniformly apply the specified adhesive to heat transfer plate's gasket groove.
Adhesion work should be done at a well-ventilated location because "S-1" and
"F-2" adhesives contain organic solvents. Work in improperly vented room is
prohibited.
Adjust the quantity of adhesive applied not to overflow the adhesive from the heat
transfer surface when the plate gasket is set on heat transfer plate.
2) Gasketting on heat transfer plate
Set plate gasket on heat transfer plate gasket groove.
At this time, be careful to prevent the gasket from run on to gasket groove wall.
The gasket expands during hot season and shrinks during cold season. When
gasketting, put the gasket in tight and or extend it.
3) Curing and pressing (Refer to P5 only if the plate gasket is type "B" or "None".)
Pile up gasketted heat transfer plate, place a weight (approx. 5kg) and a board
for curing. Perform curing time is 15 minutes and over.
Be careful not to fall over piled plates.
As recommendation, piled height is up to max. 1,000 mm.

(4) Gasketting....."Slit-In" type plate gasket
1) Gasketting
Attach the plugging part of the gasket into the slit on the outside of plate gasket groove.
Be careful not to run on to gasket groove wall.
2) Gasket Bonding
Gaskets of D-Plate front side and E-Plate back side are not “slit-in” type. Apply adhesive to the gasket groove
and set D-Gasket(s) or E-Gasket(s).
Note: For only models which require gaskets of E-plate back side
[CAUTION]
Plate gasket has two sides. It is correct when stamp and color marking can be seen. (Some models are
exception.) Before gasketting, fix any twisting of gasket and check the front and back surfaces.
Be sure to perform the following inspections before assembling a Hisaka PHE.
Checking of heat transfer plate arrangement
– While moving all the heat transfer plates toward the S-Frame side or E-Frame
side one by one, check the heat transfer plate arrangement.
– For heat transfer plate arrangement, refer to the "Plate Arrangement Drawing”
and each model's "Gasketting Manual".
Furthermore, look at the arranged heat transfer plates from the side of PHE. If
the arrangement is incorrect, heat transfer plates with the same configuration will
be lined up.
Inspection of defects on the heat transfer plate two sides and plate gasket surface
– While moving the heat transfer plates toward the S-Frame side or E-Frame side one by one, visually check for foreign
material on the two sides of the heat transfer plate gasket groove and the plate gasket surface, and for defects such as
damage and/or corrosion.
If there is any foreign material on the two sides of the heat transfer plate gasket groove and/or the plate gasket surface,
remove it using a soft cloth such as a dust cloth.
If there is any visible damage, corrosion on the two sides of heat transfer plate or the plate gasket surface, replace it with
a brand-new one.
– At the same time, check that the plate gasket is free from peeling off the heat transfer plate.
If the gasket is peeling from plate groove, re-bonding only the peeling part.
– In case of “slit-in” type (plate gasket type "A"), only D-Plate front side and E-Plate back side are to be adhered. Use
Hisaka specified adhesive.
Damage inspection for the tightening bolts and nuts
– Visually inspect the surface of tightening bolts and nuts, and if there is any damage that may interfere with tightening,
such as scratches, dents, or rust, replace it with a brand-new one.
