[. . . ] Most importantly, the multi air conditioner system is able to replenish a large amount of refrigerant compared with conventional individual air conditioners. If a single unit of the multi conditioner system is to be installed in a small room, select a suitable model and installation procedure so that if the refrigerant accidentally leaks out, its concentration does not reach the limit (and in the event of an emergency, measures can be made before injury can occur). In a room where the concentration may exceed the limit, create an opening with adjacent rooms, or install mechanical ventilation combined with a gas leak detection device. volume of the indoor unit installed room (m³) Concentration limit (kg/m³) The concentration limit of R410A which is used in multi air conditioners is 0. 3kg/m³. [. . . ] Considering functions, reserve space necessary for construction and servicing. (The figure at lower right side shows a case that 3 units are installed connectively.

(2) Install the outdoor unit so that height of obstacle surrounding the outdoor unit is kept 800mm or less from the bottom end of the outdoor unit. (3) If height of obstacle surrounding the outdoor unit is higher than the outdoor unit, measures such as discharge duct being installed is required. [1] Outdoor unit carrying in Handle the outdoor unit in care with the following items. When using a forklift, etc for loading/unloading in transportation, insert pawl of the forklift into the square hole for handling as shown below. When lifting up the unit, insert a rope sufficiently bearable to unit mass into the square hole for handling, and cord the unit from four sides. (Apply a plaster to position where rope fits outdoor unit itself so that flaw or deformation does not generate on the outer surface of the outdoor unit. ) (There provided the reinforcing plates on the side surfaces, so the rope cannot be passed. ) GOOD GOOD NOT GOOD Plaster NOT GOOD NOT GOOD Forklift Forklift Rope Plaster Square hole for handling Reinforcing plate 89 [2] Installation of outdoor unit WARNING · Perform a specified installation work against a strong wind such as typhoon or earthquake.
