Selecting Piping Size
(a)
Select the size for the high/low pressure gas pipe, low pressure gas pipe and gas pipe according to
the table 5.1. The size depends on the indoor unit total capacity connected downstream of the
Switch Box
.
(b) In case that the piping size from Table 5.1 and the piping connection size for
Switch Box
from Table
5.2 are different, use an accessory pipe according to the item 5.2(3).
