Instructions for Installing the HB-R770 Heated Bidet

Before you begin the installation process, make sure that the size and shape of the toilet is suitable for installing your new bidet. Please refer to the bidet's Product Specifications page for dimensions.
CAUTION: DO NOT CONNECT THE POWER UNTIL INSTALLATION IS COMPLETE. ONLY AUTHORIZED SERVICE PERSONNEL SHOULD GROUND THE CONNECTION.
Remove existing toilet seat
Step 1: Remove the existing toilet seat and lid by unfastening the fixation nuts under the seat hinge. Note: Keep the detached seat, lid and nuts for future use if desired.
Shutoff toilet water supply and drain toilet tank
Step 2: Turn off the water supply to the toilet by turning the shutoff valve clockwise. Drain the toilet water tank completely.
Step 3: Detach the water supply hose from the shutoff valve. (Keep all removed toilet parts together in case you move or need to reinstall them.)

Step 4: Install the T-valve into the end of the water supply hose that connects to the toilet’s water tank. 
Install T-valve into toilet water supply hose
Step 5: Reconnect the flexible water supply hose. (Note: The T-valve is standard ½-inches in size. If connecting 3/8-inch, use the conversion nut with packing before connecting the branching valve; then, connect the T-valve and valve coupling nut with packing.)
Insert bolts to bidet unit
Step 6: Insert the fixation bolts into the grooves at the bottom of the bidet unit so that they match the bolt holes of the toilet. (There are two possible dimensions to install. The outside groove is 155mm and the inside groove is 140mm.)
Secure bidet with heated toilet seat to toilet
Step 7: Insert the bolts into the holes on the toilet. Place the rubber packing on the bolt, followed by a washer, and then tighten the fixation nut.
Connect toilet water supply
Step 8: Connect the PVC flexible hose from the main unit to the T-valve and water supply inlet.
Insert toilet's deodorizor cartridge
Step 9: Insert the deodorization cartridge into the unit.
