Important Information
NOTE: This product is designed for installation with the electrical and water supplies located through the
wall.
Grounding Instructions
•This product should be grounded. In the event of an electrical short circuit, grounding reduces the
risk of electric shock by providing an escape wire for the electric current. This product is equipped
with a cord having a grounding wire with a grounding plug. The plug must be plugged into an
outlet that is properly installed and grounded.
WARNING: Risk of electric shock. Improper use of the grounding plug can result in a risk of
electric shock.
•If repair or replacement of the cord or plug is necessary, do not connect the grounding wire to either
flat blade terminal. The wire with insulation having an outer surface that is green with or without
yellow stripes is the grounding wire.
•Check with a qualified electrician or service personnel if the grounding instructions are not
completely understood, or if in doubt as to whether the product is properly grounded.
•This product is factory equipped with a specific electric cord and plug to permit connection to a
proper electric circuit. Make sure that the product is connected to an outlet having the same
configuration as the plug. No adapter should be used with this product. Do not modify the plug
provided — if it will not fit the outlet, have the proper outlet installed by a qualified electrician. If
the product must be reconnected for use on a different type of electric circuit, the connection should
be made by qualified service personnel.

NOTE: The waterline is marked inside the tank by a notch and a label.
Turn the valve adjustment screw counterclockwise to open the valve.
Allow the tank to fill. Check the water level in the tank.
To adjust the water level, use a flat-blade screwdriver to carefully turn the adjustment rod on the
inlet valve. Turning the rod counterclockwise will lower and clockwise will raise the water level.
If further adjustment is required, remove several inches of water from the tank and allow it to refill.
Confirm the water level is correct. Repeat until the correct water level is reached.
Turn the valve adjustment screw clockwise to close the valve.
Turn off the water supply.

5. Prepare the Tank
CAUTION: Risk of product damage. Confirm the wires and water supply hose will not interfere with the
vitreous shell as it is lowered into place. The vitreous shell may cause damage to the wires or hose.
NOTE: It may be necessary to disconnect the water supply hose and tape it to the floor with the wires to
keep it clear of the vitreous while it is lowered into place.
Place the pump wiring harness, level switch wire, refill tube, electrical plug, and wand wiring
harness on the floor at the location of the rear access opening and tape them on the centerline so
they will not interfere with the vitreous shell.
Clip the spray shield into place over the fill valve.

6. Install the Vitreous Shell
WARNING: Risk of personal injury. The vitreous shell weighs 105 lbs (36 kg). Use proper lifting
technique when handling the vitreous shell. Lift and position the vitreous shell with a partner.

is not placed correctly. If handled carelessly, the shell may chip or break.
With assistance, carefully pick up the vitreous shell and slowly lower it over the tank.
Remove the cap from the capped elbow port.
Connect the cleansing hose to the elbow.
Make sure the trapway in the vitreous shell seats fully in the outlet gasket. If the vitreous shell does
not sit evenly on the floor, the trapway may not be properly seated.
Adjust the vitreous shell as needed until the trapway is properly seated.
Reconnect the water supply hose if it was disconnected.
