CAUTION: The power supply must remain off until the water heater and all related piping are completely filled with water to insure that there will not be a possible problem with heating element burn out.

6.While the tank is filling, open the electrical control panel and set the thermostat(s) to the desired water temperature. If equipped with multiple thermostats, all individual thermostats may be adjusted to the same temperature set point or they may be set a 2°F to 4°F (1˚C to 2˚C) apart to step the elements on in stages.

7.Insure that any pilot switches or manual limiting switches are placed in the “ON” position.

8.When a constant flow is obtained at the faucet, it may be turned off. The temperature and pressure relief valve should be manually opened to insure that there is no captive air in the storage tank. A constant stream of water must flow from the manually opened relief valve. Release the handle on the relief valve and allow it to close after water flow is observed.

9.Carefully check the tank, pipe and fittings for any sign of a water leak. Immediately repair as needed. Open the access door to the immersion heating elements and check for leaks at the element mounting flanges. If any leak is detected, tighten the screw–in element.

START-UP

10.Insure that the electrical access panel (field wiring compartment) is closed and the heating element access panel is in place before proceeding.

11.After assuring that the tank is completely filled with water and no leaks are detected, you are now ready to start operation of the water heater.

12.Turn on the electric power at the main disconnect point. The contactors should be energized as the elements start to heat the water in the tank.

13.As the water heater starts heating, check the contactors for “buzzing” or “chattering” during operation. If noise is detected, turn off main power, open the control panel and clean the contact points of the magnetic contactor(s). Remove any dust, dirt or foreign matter that may have found its way into the contactor or other electrical components in the control panel during shipping, installation or service.

14.Close the electrical control panel and turn on main power.

15.The water heater is now ready for normal operation.

INITIAL START-UP CHECKS

The following checks should be made by the installer when the water heater is placed into operation for the first time.

WARNING:

HAZARD OF ELECTRICAL SHOCK – Before opening the access panel to perform service on any electrical component, make sure the electrical supply to the water heater is turned “OFF”. Failure to do this could result in death, serious bodily injury or property damage.

1.Allow the water heater to heat for approximately thirty minutes after following the filling and start up procedures.

2.Turn off the main electrical power to the water heater. If the power disconnect point is out of sight, lock it in the open (“OFF”) position and tag to prevent unexpected application of power.

3.Open the electrical control panel door and feel each wire connection and fuse clip for excessive temperature. If any connection is found to be excessively hot, check the tightness of the connection. Check all factory internal wiring connections and the field made main power connections for tightness.
