17ENGLISHBase construction and installation of the outdoor unit• Make sure to remove the wooden pallet before installing the outdoor unit. If you do not remove the woodenpallet, there is risk of fire during welding the pipes. If the outdoor unit 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.WARNING❋ Fix an outdoor unit firmly on the base ground with anchor bolts.❋ Manufacturer is not responsible for the damage occurred by not following the installation standards.1. Make sure that the height of the base ground is 200mm or higher to protect the outdoor unit from rain water or otherexternal conditions. Also, install a draining pit around the base ground and connect the drain pipe to the drainage.2. Considering the vibration and weight of the outdoor unit, strength of the base ground must be strong to prevent noiseand the top surface of it should be flat.3. Base ground should be 1.5 times larger than the bottom of the outdoor unit.4. Outdoor unit must be fixed firmly so that it can withstand the wind speed of 30m/s. If you cannot fix the outdoor unit onthe base ground, fix it by side or use extra structure.5. In heating operation, defrost water may form so you must really care about the drainage and waterproofing the floor. Toprevent defrost water from stagnating or freezing, construct a drainage with over 1/50 slope. (Ice may form on the floorin winter time.)6. It is necessary to add wire mesh or steel bar during concrete construction for the base ground to prevent damages orcracks.7. When installing multiple outdoor units at the same place, construct a H beam or an anti-vibration frame on the baseground to install the outdoor unit.8. After installing a H beam or an anti-vibration frame, apply corrosion protection and other necessary coating.9. When concrete construction for outdoor unit installation is completed, install an anti-vibration pad (t=20mm/0.78 inch ormore) or an anti-vibration frame to prevent vibration of the outdoor unit from transferring to the base ground.10. Place the outdoor unit on a H beam or an anti-vibration frame and fix it with the bolt, nut and washer.
