• For pipes larger than Ø 19.05mm(3/4"), drawn type (C1220T-1/2H or C1220T-H) type copper pipe must be used. If an
annealed type (C1220T-O) copper pipe is used, pipe may break due to its low pressure resistance and cause personal injury.
CAUTION
• Pour les tuyaux de diamètre supérieur à Ø 19,05 mm (3/4"), du cuivre étiré (C1220T-1/2H ou C1220T-H) doit
être utilisé. Si du tuyau en cuivre recuit (C1220T-O) est utilisé, une rupture est possible compte tenu de sa faible
