1288209-2 Intelligent Toilet

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.

Tools and Materials

Before You Begin
WARNING: Risk of electric shock. Disconnect the power before servicing.
WARNING: Risk of electrical shock. Connect only to a properly- grounded, grounding-type receptacle which is protected by a Ground-Fault Circuit-Interrupter (GFCI) or Residual Current Device (RCD). Do not remove the grounding pin or use a grounding adapter.
CAUTION: Risk of hazardous gases. If a new toilet is not installed immediately, temporarily place a rag in the floor flange opening.

Before You Begin (cont.)
NOTICE: The Canadian Electric Code requires receptacles installed in bathrooms to be located at least 39-3/8″ (1000 mm) from a bath or shower if practical,  but in no case less than 19-11/16″ (500 mm). If the installation is in Canada, install this unit in accordance with the Canadian Electrical Code, Part 1.

• Observe all local plumbing and building codes.
• Carefully inspect the new toilet for any damage.
• There is a wiring schematic on the inside of the access cover.
• Consult the Homeowners Guide for user directions.
• Consult the Homeowners Guide for troubleshooting instructions.

Prepare the Site

WARNING: Risk of electrical shock. Connect only to a properly- grounded, grounding-type receptacle which is protected by a Ground-Fault Circuit- Interrupter (GFCI) or Residual Current Device (RCD). Do not remove the grounding pin or use a grounding adapter.
CAUTION: Risk of hazardous gases. If the new toilet is not installed immediately, temporarily place a rag in the closet flange.

NOTE: If the rough-in distance is less than 12″ (305 mm) the seat may strike the wall when it is opened. Confirm the rough-in is 12″ (305 mm) before installing the toilet.

• Turn OFF the water supply.
• Remove the old toilet.
• Remove the wax residue from the flange.

NOTE: T-bolts are not included. T-bolts should be 2-1/4″ (57 mm) in length. Longer bolts will cause difficulty in installation.

• Install two 5/16″ diameter x 2-1/4″ long T-bolts into the floor flange.
• Mark the centerlines for the outlet on the floor.
• Install the electrical supply at the location shown.
• Install the water supply at the location shown.

Install the Tank

CAUTION: Risk of property damage. Do not rock or lift the tank after placement. The seal created by the wax ring may be broken, resulting in leaking.

• Position the wax ring on the floor flange.
• Remove the tank from the vitreous toilet.
• Align the tank over the floor flange and T-bolts.
• Lower the tank onto the floor flange with the slots in the base of the tank aligned with the T-bolts.
• Carefully align the tank on the centerline.
• Press down evenly to set the wax ring.

Secure the Tank

CAUTION: Risk of product damage. Do not overtighten the mounting nuts. Do not cut or shorten the T-bolts.

• Install a washer on each T-bolt.
• Thread a nut onto each T-bolt.
• Handtighten the nuts.
• Wrench-tighten the nuts one quarter turn past hand-tight with a socket wrench.
• Connect the water supply hose to the open port on the elbow.
• Connect the water supply hose to the water supply stop.
• Confirm the cap on the elbow is tight.
• Open the water supply stop.

Check the Waterline

CAUTION: Risk of property damage. Before use, close the valve using the adjustment screw to avoid overflow.
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.

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.

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.
CAUTION: Risk of product damage. Do not set the shell down hard. Gently lift and move the shell if it 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 trap way in the vitreous shell seats fully in the outlet gasket. If the vitreous shell does not sit evenly on the floor, the trap way may not be  properly seated.
• Adjust the vitreous shell as needed until the trap way is properly seated.
• Reconnect the water supply hose if it was disconnected.

Connect the Wires
