[. . . ] Unless the piping is installed correctly, gas leak may be caused during operation such as pressure boosting. Conduct a leak test of the pipe connecting parts correctly. 2) In case the actual length of the piping exceeds the standard piping length, accurately add the refrigerant referring to Additional Refrigerant Amount . 3) Thermal insulation materials for the branch pipes are not supplied as accessories. [. . . ] Components The following parts are supplied as accessories of the branch pipes. Part Installation Instructions Branch pipe Gas side Liquid side Refrigerant Piping Tolerance of Pipe Length Indoor Unit B Indoor Unit A Quantity 1 1 1 Shape This booklet Use For installation works For refrigerant pipe branching and collection Tolerance of Pipe Head Pipe Length (One Direction) Difference of branch piping length b-a, or a-b Below 15m (actual length) Height Defference Outdoor Unit Indoor Unit H Outdoor Outdoor Unit Unit Installed Installed Above Below Indoor Indoor Unit Unit Below 30m Below 15m Branch pipe Model (RAV-) Full length L+a or L+b Branch piping a, b Between Indoor Units h Remarks SM1100AT-E SM1400AT-E Below 50m (actual length) Below 10m Below 0. 5m Less than 10 bends Outdoor unit Refrigerant Piping Cautions When planning a layout for Units A and B, comply with the following: 1. The lengths after branching ("a" and "b") should be equal if feasible. Install Units A and B so that the difference of the branching lengths becomes less than 10m if the lengths cannot be equal due to the branch pipe position. Install Units A and B on the same level. If Units A and B cannot be installed on the same level, the difference in level should be limited to 0. 5m or less. Be certain to install Units A and B in the same room. Units A and B cannot be operated independently each other. 2 Piping Materials and Sizes Use copper tube of Type 1220 in JIS H 3300 (Copper and copper alloy seamless pipes and tubes) with 40mg/10m or less in the amount of oil stuck on inner walls of pipe and 0. 8mm in pipe wall thickness for diameters 6. 4, 9. 5 and 12. 7mm and 1. 0mm, for diameter 15. 9mm. Never use pipes of thin wall thickness such as 0. 7mm. Branch Pipe Now the refrigerant pipe is installed using branch pipes supplied as accessories. Bend and adjust the refrigerant piping so that the branch pipes and pipe after branching become horizontal. (Otherwise malfunction will be caused by noise) 5 Raccordement pour les cassettes et gainable. La configuration est automatique <<4-Way Ceiling Cassette and Built-In Duct>> Electrical Wiring · Be certain to install wires by connecting them to terminals of the same numbers according to the following wiring diagram. · Exercise reasonable caution with the following when installing wires. No. 1 Item Remote control wiring Description (1) Connect the remote controller only to the main unit. (2) Install jumper wires between the main unit and sub unit. The jumper wires of the remote controller have no polarities. (1) Install wires from the outdoor unit to the main unit as in usual wiring. (Wires of (1), (2) and (3)) (2) Install Wires (1) and (2) only when installing connection wires from the master unit to the sub unit. 2 Wiring internal and external connection wires · All two-dot chain lines show wiring jobs to be performed at the site. · The remote controller circuits are low voltage circuits. These circuits must not be made to directly contact internal and external wires or contained in the same conduit tubes that house internal and external wires. (Otherwise malfunction will be caused by noise) Remote controller Pas de fil sur la borne 3 de l'unité suiveuse.
