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.

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.

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.

Keep fire-fighting equipment when handling flammable media.

If the flammable media ignites during operation or maintenance, it can lead to a major accident.

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 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.

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.

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.

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.

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.

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.

P1

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 place objects on plate pack.

It may cause deformation of heat transfer plate.

Falling object may cause injury during operation.

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.

Do NOT shorten guide bar by cutting.

It makes disassembling of the PHE impossible.

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.

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.

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.

Do not apply impact pressure 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.

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.

CAUTION

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.

Secure working space around PHE.

Adequate piping design is required, taking into account the working space for disassembly and tightening device.

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.

Confirm that the nozzle orientation in the "Plate Arrangement Drawing" and "Assembly Drawing".







Provide vending 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.

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.

8-2 Pressure/Leak Test for PHE and System Pressure Test

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.

8-3 Initial Flushing for Piping

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.

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

F-2

Silicon type

Double-sided tape

General use

For food products

For silicon gaskets

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.

NG

5kg

P12

(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.

12-4 Inspection

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.

GOOD or

NG or

Heat transfer plate patterns



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.

P13

12-5 Assembly

Assembly preparation

(1) Prepare the ratchet spanner or the automatic tightening device.

(2) Grease up the tightening bolts after cleaning all tightening bolt threads.

Assembly work

(1) Move all heat transfer plates that have been checked/inspected plate arrangement to the S-Frame side, and move the E-Frame to the S-Frame side.

(2) Place the tightening bolts for position 3, 4, 11, and 12.

[NOTE]

 Place the tightening bolts and nuts in four positions, below the upper nozzles and above the lower nozzles. (If there are long bolts and short bolts, place the long bolts first.)

(3) Tighten the bolts to ensure the dimension in position 3, 4, 11 and 12 should be equal.

(4) Slowly tighten the bolts in order of 3411123 and so on.

[NOTE]

 If you have two sets of ratchet spanners and/or automatic tightening device, slowly tighten two tightening bolts that are located diagonal, in order, 3 and

4, 11 and 12, simultaneously.

(5) Where 3, 4, 11, and 12 become hard to tight, place all tightening bolts and nuts in position 1 to 14.

(6) Tightening length of 1 to 14 should be equal.

(7) Slowly tighten the tightening bolts in order of 1, 2, to 13, 14, to 1.

[NOTE]

 If you have two sets of ratchet spanners and/or automatic tightening device, slowly tighten two tightening bolts that are located diagonal, in order, 1 and 2

-> 13 and 14 -> 3 and 4 -> 11 and 12 -> … -> 5 and 6 -> 7 and 8, simultaneously.

The difference between each tightening length shall be within 10mm.

Further, the difference shall decrease to 5mm, 3mm and 1mm from 10mm when it gets harder to tighten up in order to prevent galling of the tightening bolts and nuts.

(8) Repeat step (7) until the tightening below-specified lengths.

 In case that plate gaskets are not to be replaced: Tightening lengths recorded before disassembly

 In case that plate gaskets are to be replaced: Tightening Length Max. on the nameplate
