Pour plier un tube, donnez un rayon le plus grand possible de façon à ne pas écraser le tube, le rayon de courbure doit être entre 30 et 40, ou plus.
Le fait de brancher le tube du côté gaz en premier facilite le travail. 
Le tube de connexion est spécial pour le R410A.
Elevación máx.: A máx=10m
En caso de que la elevación A sea superior a 5 m, el filtro de aceite debe instalarse cada 5 ~ 7 m.
Longitud máx.:B máx=15m
En caso de que la longitud del tubo B sea superior a 10 m, deberá cargarse el refrigerante a razón de 20 g / m.
Utilisez la même méthode que pour l'unité intérieure. Desserrez les vis sur le bornier et insérez entièrement les fiches dans le bornier, serrez alors les vis.
Insérez le câble en fonction du numéro de borne de la même manière que pour l'unité intérieure.
Si le câblage n'est pas correct, le bon fonctionnement ne peut pas être assure et le contrôleur peut être endommagé. 
Fixez le câble avec une pince.
Si vous utilisez un coude de drainage, veuillez le fixer comme sur la figure. (Remarque :HSU-09RD03/R2(SDB), HSU-12RD03/R2(SDB) specifications
