11.2- Hose connecting valves (Flex2 and Flex4)
To facilitate the parallel connection of the valves, described in the previous paragraph, you can use the
accessory Flex2 (for 2-pipe systems) and Flex4 (for 4-pipe systems). The kit consists of hoses with braided
stainless steel (with 3/4 "for the valve) and brass TEE to connect the pipes from 3/4". You can also directly
connect the hoses to the coil, inserting an adaptor nipple 1/2 "-3/4" (nipple not supplied).
