As the world's largestmanufacturer of heat Exchangers, we are very proud of our products and services. We value youas our customer and wish to assure your satisfaction.

3 We have prepared this Instruction Manualto assist you with your alfa laval Plate heat Exchanger in various situations. We suggest thatyou look through it carefully, and, above all, make it readily available to any personnel who mayneed it for name Plate - and the identification of the equipmentModel type and manufacturing numbers(s)A name Plate like the one shown below is fixed to the apparatus as shown above andit gives the following name Plate - and the identification of the equipmentWHENEVER USING THE MANUAL, CHECK FIRST THAT THESERIAL NUMBER ON THE FRONT COVER IS IDENTICAL TOTHAT ON THE NAME Plate OF THE ALL CORRESPONDENCE WITH alfa laval , PLEASE REFER TO THE MANUFACTURING SERIAL NUMBER, FORTRUE IDENTIFICATION OF THE CONTACTING alfa laval ABOUT A PART FORYOUR Plate heat Exchanger , BE SURE TO STATE THEMANUFACTURING SERIAL NO.

4 (S), AND MODEL instruction manual has been issued for many differentmodels of alfa laval industrialPHEs. There are separatemanuals for industrial, sanitary, spiral, alfa rex, brazed & evaporator/condensorheat exchangers. this section, names of heat Exchanger parts are mentioned forthe first time. For your information, see Chapters 4A or otherwise agreed, alfa laval delivers the Plate heat Exchanger ready to be put inservice upon means that theplate package is tightened to its correct measurement it be necessary, however, to store the equipment for alonger period (1 month or more) before, certain precautions shouldbe made in order to prevent unnecessary wear of the equipment.

5 Preferably, the heat Exchanger should bestored inside, in a room with a temperaturearound 15 to 20 degrees Celsius (60 to 70degrees Fahrenheit) and humidity around 70% should ABSOLUTELY NOT be anyOZONE-PRODUCING equipment in the room,like electric motors or arc-welding equipment,since ozone destroys many rubber materials(cracking).Do not store organic solvents or acids in heat or ultraviolet the PHE with a non-transparentplastic film is a good precaution. Use oftransparent film can alter paint color if unit isstored in direct tightening bolts should be well coveredwith good rust preventing coating, suitabletypes (LUBRIPLATE FGL-2 or Equivalent) andif not connected to the pipe system, the con-nections should be the heat Exchanger must be stored outdoors,the precautions mentioned above should betaken as far as practical.

6 The need for protec-tion against the climate etc. is of course evenmore important in this for any reason the heat Exchanger isremoved from service for a long period, it isadvantageous to follow the advice above, evenif the equipment is not moved from the heat Exchanger should be VENTED ANDDRAINED, and depending on the media processed, it is recommended to RINSE ANDDRY it, before it is the heat Exchanger is lifted, strapsshould be placed around tightening bolts on both sides of the unit, as shown in picture. Iflifting lugs or lifting eyes are provided, alwaysuse chains or lifting cables rated above thepublished weight of the heat LIFT BY THE CONNECTIONS OR THE STUDS AROUND THEM!

7 CONTINUEDIf Lifting Lugs are providedIf you are to lift the heat Exchanger itself, strapsshould be used. They should be placed asshown on the smaller units (4 connected size smaller)typically two lifting lugs are required instead of !Never lift by the connections or the studsaround information necessary for the preparation of the foundationappears on the data sheet provided by alfa some cases (installation on board a ship,when processing corrosive liquids, etc.) it maybe practical to place the heat Exchanger in aDRAINAGE BOX (with capacity for the totalvolume of the heat Exchanger ).

8 The outlet ofthe drainage box should be generouslydimensioned, not less than (2 ) 50 connecting any piping to the heat Exchanger , MAKE SURE THAT ALLFOREIGN OBJECTS HAVE BEEN FLUSHED OUT OF THE SYSTEM!PLEASE OBSERVE THATThe measurements given in the picture aboveare recommended by alfa laval , it isnecessary to leave free space around theequipment, to provide access and make futureservice possible. Except for a place to put theplates, if removed from the heat Exchanger ,NO FURTHER SPACE is required forservicing the OBSERVE THATThe measurements given in the picture arerecommended by alfa laval , to providereasonably good working conditions duringinstallation of the heat Exchanger as well asfor future maintenance and service.

9 If floorspace is restricted, the dimensions suggestedcan be reduced. It is left to the purchaser to decide just how much access space is free space foropening and field should be kept freefrom fixed (100mm)2 (50mm) ensure that no measurable stress isplaced on the heat Exchanger by the OFF VALVESTo enable the heat Exchanger to be openedwhen necessary shut off valves should be pro-vided on all RELIEF DEVICESIt is the responsibility of the user to ensure that the required pressure relief devices areproperly installed prior to initial operation. Referto the applicable Code(s) and correspondingStandard(s) for proper size requirements ofthese pressure relief ON THE PRESSURE Plate (REAR COVER)Some Plate heat exchangers may also haveconnections on the pressure Plate .

10 In suchcases, it is important to check against thedrawing or the name Plate that the Plate packhas been tightened to the right measurementbefore the piping is piping is connected to the pressureplate, a short 90ospool piece shall be installedbetween the heat Exchanger and the should be directed upwards or side-ways. This simplifies pressure Plate removalduring of both sides of the heat exchangermust be provided. This is important and enables air to be drawn from the systemduring start-up. It also enables air or gas to be removed during operation, and it enablesfaster Flanges are provided on certain modeltypes due to interference.
