Page 12: Piping Installation
PIPING INSTALLATION NOTE: The most effective means for preventing deterioration from accelerated corrosion due to galvanic and stray current is the installation of dielectric fittings/unions. The installation of these fittings is the responsibility of the installing contractor. 1. Connect the cold water inlet and hot water outlet to the appropriate connections as shown; refer to the drawing for location and sizes. -
Page 13: Electrical Installation
ELECTRICAL INSTALLATION 1. Enter electric enclosure with properly sized feeder leads. Be sure to properly ground the water heater. 2. Install these power leads into the box lugs on the terminal block or magnetic contactor. 3. Torque screws per torque chart included in Section VI. -
Page 14: Scheduled Maintenance And Operation
MAINTENANCE AND OPERATION The water heater is automatic in its operation. It will maintain a full tank of water at the temperature setting of the thermostat. The water heater should not be turned on without first making sure that the tank is full of water and that all air has been released. -
Page 15: Annual Inspection
ANNUAL INSPECTION 1. Flush tank as follows a. Shut off power supply. b. Close valve on hot water outlet piping. c. Open valve on drain piping. d. Cold water inlet line pressure will be strong enough to flush sediment from the bottom of the tank out through the drain. -
