HEATERS EQUIPPED FOR ONE VOLTAGE
ONLY: This water heater is equipped for one type
voltage only. Check the rating plate near the bot-
tom access panel for the correct voltage. DO NOT
use this water heater with any voltage other than
the one shown on the model rating plate. Failure to
use the correct voltage can cause problems which
can result in DEATH, SERIOUS BODILY INJURY, OR

2. Open the cold water supply valve to the water heater. BLACK
NOTE: The cold water supplyvalve must be left open RED

3. To insure complete tilting of the tank, allow air to exit by
opening the nearest hot water faucet. Allow water to run
until a constant flow is obtained. This will let air out of the
water heater and the piping.
ACAUTION
Never use this water heater unless it is completely
full of water. To prevent damage to the tank and
heating element, the tank must be filled with
water. Water must flow from the hot water faucet
before turning "ON" power.
4. Check all new water piping for leaks. Repair as needed.
