home as well as the outside faucets to drain as much water out of the plumbing system as

turning the power back on to your water heater.

IF YOU WISH TO USE COPPER PIPING FOR YOUR INSTALLATION AND WILL BE
SOLDERING THE JOINTS, DO NOT APPLY HEAT NEAR YOUR CONTROL VALVE, BYPASS
ASSEMBLY, 1” NPT CONNECTOR YOKES, OR THE DRAIN FITTINGS; OTHERWISE
SERIOUS DAMAGE TO THESE PARTS COULD OCCUR. ALWAYS SOLDER JOINTS WITH
THESE COMPONENTS DETACHED. IF YOU ARE
USING COPPER ADAPTERS TO CONNECT TO
THE 1” NPT CONNECTOR YOKES, IT IS
RECOMMENDED THAT YOU SOLDER A 6 INCH
PIECE OF COPPER PIPE INTO EACH OF THE
CONNECTION ADAPTERS AWAY FROM THE
VALVE, THEN LET THEM COOL OFF BEFORE
THREADING THEM ONTO THE 1” NPT
CONNECTORS.
