INSTALLATION INSTRUCTIONS
Attaching the hinge anchor
• Place integrated anchor into anchor holes provided
on the toilet pan.
• Place Anchor Plate over the integrated anchor and
Insert screws.
• Tighten the screw and fasten anchor plate to the
integrated anchor.
Installing the seat
• Align seat pins with the seat hinge sockets and apply
downward pressure until you feel and hear a “click”.
This “click” will signify the seat pin is locking into posi-
tion. With care - adjust the hinge anchors and position
the hinge anchors so the seat is aligned with the outer
edges of the toilet pan.
• When the toilet seat has been aligned and is in the
desired position, carefully unfasten the seat from the
hinge anchors. Please refer to step 3 of the process
to learn how to unfasten the seat. Be sure to unfas-
ten the seat gently so the integrated anchors and pin
positions don’t move.
• Once toilet seat has been removed, proceed to firmly
tighten screws and fasten anchor plate to the inte-
grated anchor (please see step 1) so that toilet seat
remains in its desired final position.
Removing the toilet seat with quick release
technology
To remove the seat, place the seat in its open position,
and locate the release-buttons in the center of each hinge.
Press the release-buttons and lift the seat upwards.
This should unlock the seat.
To re-install the seat. Align seat pins with the seat hinge
sockets and apply downward pressure until you feel and
hear a “click”. This “click” will signify the seat pin is locking
into position.

TOILET SEAT INSTALLATION INSTRUCTIONS

slightly loose to allow for final adjustments later in
this process.**
