GSW Electric Water Heater P/N 61515 REV. G (05-03) User Manual

Normal Operation: When hot water is being used, cold water enters the

bottom of the heater (either bottom feed or by diptube), and the bottom

element will begin to heat the cold water. If lots of hot water has been

used, the upper thermostat will take priority and the top portion of the

heater will be heated. Once heated, the thermostat will flip down to the

lower thermostat to heat the lower portion.

1. Close the drain valve, and then open a hot water faucet.

2. Open the cold water supply valve.

3. When water runs out of the hot faucet, the tank is full.

4. Check the system for leaks.

If the power is to be turned off during the cold season and the tank is

exposed to freezing temperatures, the water heater must be drained.

Water will expand when it freezes and can damage the heater.

Completely drain as follows:

1. Make sure the electrical supply to the water heater is "OFF".

2. Turn off cold water supply.

3. Connect a garden hose to the end of the drain valve and direct this to a

point lower than the heater.

4. Open a hot water faucet.

5. Open the drain valve on the heater - drain, keeping the drain valve open

during the shutdown period.

6. To refill the heater, see 

'Filling Tank' section.

Check Here

1. Are the fuse and wire sizes correct?

2. Is the certified relief valve installed?

3. Are you sure that in case of water leakage, the building,

furniture, carpeting or other property will not be dam-

aged?

4. Has the relief valve been piped to a suitable drain point?

5. Is the relief valve discharge unobstructed?

6. Is the heater completely filled with water?

7. Is the cold supply valve open?

If the answer to the above are yes, turn on the power and enjoy all the hot

water you need, all the time.

In order to reduce the risk of scald injury, thermostats are factory set at

140°F (60°C). The thermostats operate automatically. They can be adjust-

ed to provide warmer or cooler water temperature. The setting of 140°F

(60°C) has been proven to be most satisfactory from the standpoint of

operational costs and safety. We recommend you keep the thermostats

adjusted to 140°F (60°C). If adjustments are made set both thermostats to

the SAME setting (if applicable).

Do not supply power to this water heater until you have verified

that the unit is completely filled with water. 

To ensure that the water heater is full of water and that all the air

has been purged from the system, run all the hot water faucets in

the house continuously for three (3) minutes.
