Water Supply Connections
IMPORTANT: Do not
apply heat to the HOT or
COLD water connections. If
sweat connections are used,
sweat tubing to adapter

fittings will permanently
damage the dip tube.
NOTICE: The National

instructions. Local codes
or plumbing authority
requirements may vary
from the instructions or
diagrams provided and
take precedent over these
instructions.
Vacuum Relief Valve
(Not Supplied)
If required, install per local codes
and valve manufacturer’s
instructions.
