WARNING

Make sure that all water supply lines have been flushed and then completely turned off before beginning

installation. Debris in supply lines can cause valves to malfunction.

Turn OFF electrical power to the electrical outlets, then unplug all electrical units prior to installation. Electrical

power MUST remain off until installation is complete. After installation is complete, turn on the water supply

first, then turn on the electrical power.

Installer's hardware must be appropriate for wall construction. Wall anchors must have a minimum pull-out

rating of 1,000 pounds.

NOTICE

Overtightening fasteners can damage the Terreon material. Use caution when tightening bowl and sprayhead

fasteners.

IMPORTANT

Read this entire installation manual to ensure proper installation. When finished with the installation, file this

manual with the owner or maintenance department. Compliance and conformity to local codes and ordinances

is the responsibility of the installer.

For optional soap dispenser, refer to Installation Instructions for Express® Lavatory System MG-Series

Components Assembly

To access air valve:

Remove access panel by removing (5) screws and finishing washers using a 5/32" Allen socket wrench.

To remove sprayhead:

Remove (3) bolts located underside of bowl neck. Carefully remove sprayhead from bowl.

To access aerator and pushbutton assembly:

Remove (2) screws and washers from the access plate assembly using a 1/8" Allen socket wrench. The access plate assembly

is located underneath the sprayhead at (2) places. The assembly will drop down to access the lens, housing flow control, tube

connector and pushbutton assembly.

To remove/reassemble pushbutton assembly:

Remove one screw (P/N 160-165) from the pushbutton bracket. Hold the housing with the piston and spring together while

removing the remaining screw (P/N 160-165).

After the pushbutton housing is removed, remove the nut (P/N 110-115) and then the bracket (P/N 140-743) from the pushbutton

assembly. Remove the spacer (P/N 182-115) and pushbutton assembly (P/N S08-340) from the sprayhead.

To reassemble the pushbutton assembly, first insert the pushbutton into the hole in the sprayhead housing as shown below. Slide

the spacer onto the back of the pushbutton (inside the sprayhead housing) as shown. Attach the bracket (P/N 140-743) to the

pushbutton and secure into place with the nut (P/N 110-115). Insert the spring and piston into the housing. While holding the

assembly together, insert one screw (P/N 160-165) into the housing.

Insert the screw with housing into the bracket on the pushbutton assembly. After the first screw is inserted, rotate the housing so

that the piston is facing the front of the unit. Insert the second screw (P/N 160-165) into the bracket and secure the housing in

place.
