LAVATORIES -TRAINING INFORMATION POINTS -LOWER CONNECTIONS

Training Information Point
Water and waste connections are inside the toilet junction box. The junction box is inside the wash basin cabinet or behind the toilet shroud.
Bolts and fittings attach the lavatories to the seat tracks. Four washers are necessary at each of the fittings for proper bolt thread engagement. Put washers between the upper fitting and the lavatory as necessary to make the lavatory perpendicular to the floor. Install these washers with the tabs down. Put the remaining washers under the bolt head with the tabs up.
You must install special seat track fittings (not shown) at lavatory locations at the seat track splices. It is possible that tolerance build-ups in the seat tracks will not permit you to install the standard fittings at the seat track splices. The special fittings align to the seat track lip to permit installation of the fittings at the splice.
The upper fitting has an eccentric hole. When you install a lavatory, position all the fittings with the offset forward. If the fitting holes do not line up, rotate the aft pair of upper fittings 180 degrees.
