OPERATION

GENERAL

Refer to the Features and Components section of this manual (pages 7 & 8) for the location of components mentioned in the instructions that follow.

NEVER turn on power to the water heater without being certain the water heater is filled with water and a temperature and pressure relief valve is installed in the relief valve opening.

DO NOT TEST ELECTRICAL SYSTEM BEFORE HEATER IS FILLED WITH WATER. FOLLOW FILLING AND START-UP INSTRUCTIONS IN OPERATION SECTION.

FILLING THE WATER HEATER

1.Turn off the electrical disconnect switch.

2.Close the water heater drain valve.

3.Open a nearby hot water faucet to permit the air in the system to escape.

4.Fully open the cold water inlet pipe valve allowing the heater and piping to be filled.

5.Close the hot water faucet as water starts to flow. The heater is now ready for STARTUP and TEMPERATURE REGULATION.

INITIAL START UP

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

1.Turn off the electrical disconnect switch.

2.Open the front panel, check all water and electrical connections for tightness. Also check connections on top and side of heater. Repair water leaks and tighten electrical connections as necessary.

3.Depress the red manual reset button on each Thermostat/ECO combination control (Surface Mount Control Models only).

4.Turn on the electrical disconnect switch.

5.Observe the operation of the electrical components during the first heating cycle. Use care as the electrical circuits are energized.

6.Close the front panel.

Temperature control and contactor operation should be checked by allowing heater to come up to temperature and shut off automatically. Use care as the electrical circuits are energized.

DRAINING THE WATER HEATER

The water heater must be drained if it is to be shut down and exposed to freezing temperatures. Maintenance and service procedures may also require draining the heater.

1.Turn off the electrical disconnect switch.

2.Close the supply water inlet valve to heater.

3.Attach hose to outlet opening of drain valve and direct end to drain.

4.Open a nearby hot water faucet and the heater drain valve.
