The refrigerant R410A which is used in the air conditioner is safe, without the toxicity or combustibility of ammonia, and is not restricted by laws to be imposed which protect the ozone layer. However, since it contains more than air, it poses the risk of suffocation if its concentration should rise excessively. Suffocation from leakage of R410A is almost non-existent. [. . . ] Therefore, set the T-shape joint so that oil does not enter directly. <Ex. 1> Header unit A Follower unit B Follower unit C Height difference between outdoor units H3 5 m Header unit A Outdoor unit T-Shape branching main piping La Follower unit B LA Lb Lc L1 Main connecting piping between outdoor units Length corresponded to farthest piping between outdoor units LO 25 m Branching piping L2 1st branching section Height difference between outdoor and indoor units H1 50 m L3 Connecting piping of indoor unit a g b Branching header L9 <Ex. 2> c FS unit Header unit A OK Follower unit B Follower unit C h i j k <Cooling only> <Cooling only> Indoor unit Equivalent length corresponded to farthest piping L 150 m Lj L4 L5 e n p q L6 f L7 FS unit Lh o L8 Equivalent length corresponded to farthest piping after 1st branching Li 50 m NO GOOD Height difference between indoor units H2 35 (Upper outdoor unit) Height difference between indoor units in group control by one FS unit H4 0. 5 m FS unit l d m Indoor unit Indoor unit which FS unit control wiring is connected. <Group control> When connecting the plural indoor units to single FS unit.

Attached connection cable can be used up to 5 m in pipe length between indoor unit and FS unit. When the pipe length between indoor and FS unit exceeds 5 m, be sure to use the connection cable kit (RBC-CBK15FE). Note 1) Combination of outdoor unit : Header unit (1 unit) + Follow unit (0 to 2 units). Header unit is outdoor unit nearest to the connected indoor units. Note 2) Install the outdoor units in order of capacity. (Header unit > Follow unit 1 > Follow unit 2) Note 3) Refer to outdoor unit combination table in page 5. Note 4) Piping to indoor units shall be perpendicular to piping to the head outdoor unit as <Ex. Do not connect piping to indoor units in the same direction of head outdoor unit as <Ex. 2>.

For an airtight test, connect a nitrogen gas bomb as shown in the figure below, and apply pressure. Be sure to apply pressure from the service ports of the packed valves (or ball valves) at liquid side, discharge gas side, balance pipe and suction gas side. An air tight test can be only performed to the service ports at liquid side, discharge gas side, and suction gas side of the outdoor unit. [. . . ] Vrifiez ensuite si tous les clapets bille du ct aspiration du gaz, du ct vacuation du gaz, du ct liquide et du ct quilibre sont compltement ferms. Si le niveau de pompage vide n'est pas descendu en dessous de 755 mmHg aprs 2 heures ou plus, poursuivez le pompage vide pendant 1 heure ou plus. Si vous ne parvenez pas atteindre 755 mmHg ou moins en 3 heures ou plus de pompage vide, vrifiez s'il y a une fuite. Lorsque le niveau de pompage vide a atteint 755 mmHg ou moins aprs 2 heures ou plus, fermez compltement les vannes VL et VH du collecteur manomtrique, arrtez la pompe vide, laissez-la en l'tat pendant 1 heure, puis vrifiez que le niveau de pompage vide ne change pas.
