STEPS TO INSTALL YOUR WATER HEATER (Continued)
D. Open the MAIN water supply valve and the water heater will begin to fill.
E. When the water heater has filled completely, and water
from nearby faucets runs smooth with no more air bubbles, close the faucets.
CAUTION: Be sure to allow all air to vent from the tank. The upper heatina element will burn out if air is trapped at the top of the tank and the element is not covered with water when power is turned on.
E Check your plumbing work for leaks. If any are found,
repair before doing the electrical wiring. READ THE CAUTION NOTE FOLLOWING STEP 2 ON PAGE4.
, ELECTRICAL WIRING.
Wire the water heater (240V) to the main fuse or circuit breaker panel. Read all of the following notes, warnings and
cautions before beginning. Refer to FIG. 3A thru 3F on Pages 7 and 8.
NOTE: Remove the water heater front panel (grasp with both hands and pull outward) and the junction box cover.
CAUTION: BE SURE TO GROUND THE WATER HEATER. Rigid metal conduit (FIG. 3A), between the main pane( and the water heater junction box, with approved end fittings, is the preferred way to ground (check codes on the use of flexible conduit). If making a separate ground wire connection (FIG.
3B), a ground screw is provided in the water heater junction box.
