InstallationChoosing the installation location• Installing by or – Height of the wall on the front side should not be higher than 1500 mm (59 inch).– Height of the wall on the air inlet side should not be higher than 500 mm (20 inch).– Height of the wall on the side is not limited.– If the height of the wall exceeds by certain value (h1, h2), additional clearance [(h1)/2, (h2)/2 : Half of theexceeded distance] should be added to the service space (S1, S2).1500 (60) h1500 (20) h2Front sideAir inlet sideS1+h1/2 S2+h2/2Unit : mm (inch)WARNING• Make sure to remove the wooden pallet before installing the DVM CHILLER. If you do not remove the woodenpallet, there is risk of fire during welding the pipes. If the DVM CHILLER is installed with wooden pallet on, andit was used for long period time, wooden palette may break and cause electrical hazard or high pressure maydamage the pipes.• Fix DVM CHILLER firmly on the base ground with anchor bolts.CAUTION1 Make sure that the height of the base ground is 20 mm (8 inch) or higher to protect the product from rain water or otherexternal conditions. Also, install a drainage hole around the supporting base and connect the drain pipe to the drainage pit.2 Considering the vibration and weight of the product, strength of the base ground must be strong to prevent noise and thetop surface of it should be flat.3 Area of the base ground should be 1.5 times larger than the bottom of the product.4 Product must be fixed firmly so that it can withstand the wind speed of 30 m/s (100 ft/s). If you cannot fix the DVM CHILLERon the supporting base, fix it by side or use extra structure.5 In heating operation, defrost water may form so you must pay close attention to the drainage and waterproofing of thefloor. To prevent defrost water from stagnating or freezing, construct a drainage pit with over 1/50 slant to prevent iceformation on the floor in the winter time.6 It is necessary to add wire mesh or steel bar during concrete construction for the base ground to prevent damage or cracks.7 When installing multiple DVM CHILLERs at the same place, construct an H beam or a vibration-isolation frame on the baseground to install the product.8 After installing an H beam or a vibration-isolation frame, apply corrosion protection and other necessary coating.9 When concrete construction for product installation is complete, install an isolation pad (t = 20 mm (0.78 inch) or more) or avibration-isolation frame to prevent vibration of the product from transferring to the supporting base.10 Place the product on an H beam or a vibration isolation frame and fix it with the anchor bolt, nut and washer. (The bearingcapacity of the anchor bolt has to be over 3.5 kN (787 lbf))• Manufacturer is not responsible for the damage occurred by not following the installation standards.
