GSW Electric Water Heater P/N 61515 REV. G (05-03) User Manual
Page 3
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.
Filling Tank
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.
NOTE: When filling, avoid water spillage. Do not allow the insula-
tion of the heater to get wet as water can cause electrical malfunction.
Draining Tank (completely)
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.
Installation Check List
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.
IV) OPERATION
Temperature Adjustment
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).

CAUTION
FOR YOUR SAFETY, BE AWARE THIS WATER HEATER IS
CAPABLE OF PRODUCING HOT WATER AT A TEMPERATURE
SUFFICIENT ENOUGH TO CAUSE SCALDING INJURY. READ
INSTRUCTIONS CAREFULLY BEFORE OPERATING THIS
UNIT. INCREASING THE THERMOSTAT SETTING ABOVE
THE PRE-SET TEMPERATURE MAY CAUSE SEVERE BURNS
AND CONSUME EXCESSIVE ENERGY. HOTTER WATER
INCREASES THE RISK OF SCALD INJURY.
150°F (66°C) - 2 SECONDS
140°F (60°C) - 6 SECONDS
130°F (54°C) - 30 SECONDS
NOTICE
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.
