The tools and parts which will be newly prepared in the following items should be restricted to exclusive use.5: Newly prepared (It is necessary to use it exclusively with R410A, separately from those for R22 or R407C.)5: Former tool is available.54 SELECTION OF INSTALLATION PLACE6Installation space65 CARRYING IN THE OUTDOOR UNIT7Weight centre and weight86 INSTALLATION OF THE OUTDOOR UNIT81. Install the outdoor unit on a higher foundation than the snowfall or set up a stand to install the unit so that snowfall will not affect the unit.82. Mount a snowfall-hood onto the air inlet and the air outlet.81. To install multiple outdoor units, arrange them with 20mm or more spaces in between. Fix each outdoor unit with M12 anchor bolts at 4 positions. 20mm projection is appropriate for an anchor bolt.82. When drawing out the refrigerant pipe from the underside, set the height of the stand to 500mm or more.93. Do not use 4 stands on the corner to support the outdoor unit.94. Mount the vibration-proof rubber (including vibration-proof blocks) so that it fits under the whole clamping leg.95. Be careful of the connecting arrangement of the header unit and follower units. Set the outdoor units in order of capacity from the one with the largest capacity.

Apply pressure 0.3MPa (3.0kg/cm²G) for 5 minutes or more.152. Apply pressure 1.5MPa (15kg/cm²G) for 5 minutes or more.153. Apply pressure 3.73MPa (38kg/cm²G) for approx. 24 hours.15Vacuum drying16Adding refrigerant17Full opening of the valve18F-GAS label181. Stick the enclosed refrigerant label adjacent to the charging and/or recovering location.182. Clearly write the charged refrigerant quantity on the refrigerant label using indelible ink. Then, place the included transparent protective sheet over the label to prevent the writing from rubbing off.183. Prevent emission of the contained fluorinated greenhouse gas. Ensure that the fluorinated greenhouse gas is never vented to the atmosphere during installation, service or disposal. When any leakage of the contained fluorinated greenhouse gas is de...184. Only qualified service personnel are allowed to access and service this product.185. Any handling of the fluorinated greenhouse gas in this product, such as when moving the product or recharging the gas, shall comply under (EC) Regulation No. 842/2006 on certain fluorinated greenhouse gases and any relevant local legislation.186. Periodical inspections for refrigerant leaks may be required depending on European or local legislation.187. Contact dealers, installers, etc., for any questions.18Heat insulation for pipe18Finishing after connecting pipes188 ELECTRIC WIRING19Power supply specifications19Specifications for communication wiring20Connection of power wires and communication wires211.
