Step 2:  Attach Flex Hoses. Let the universal ends of the 
hoses hang inside the cabinet for now. (Figure 22).
Note: Be sure the valve handles are in a position that 
enables them to be opened and closed. Check the 
swivel ends of the hoses (Figure 21). Gaskets must be 
in the hose for proper seal.
