MG-2/AST4 Installation
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
document 215-1585.
Separate parts from packaging and make sure all parts are accounted for before discarding any packaging
material. If any parts are missing, do not begin installation until you obtain the missing parts.

Installation MG-2/AST4
Mount the Frame
2
Loosen, but do not
remove the bottom
A
access panel screws.
Anchoring the frame to a wall that is not flat may cause the
frame to bend, making it difficult to reinstall the access panels.
If necessary, use shims to compensate for wall distortion.
Once you have positioned
the frame such that it is level
and flat against the wall or
shimmed, use the 3/8" bolts
C
and washers (6 places) to
mount the frame to the wall.
Remove the top access panel
screws and washers and
B
remove the access panel.
Install the Bowl
3
If the fixture has a soap option, refer to the soap system
installation manual (215-1585) before installing the bowl assembly.
Secure the bowl to the wall
anchors with two 3/8" bolts and
B
washers. Do not overtighten.
Attach the bowl to the frame using the
four ¼-20 x ½" pan-head screws and
A
washers. Do not tighten screws.
Tighten the pan-head screws. Do not overtighten.
If necessary, adjust the sprayhead body to fit
closely to the wall by adjusting the sprayhead
C
mounting bolts. Refer to the components
illustration for bolt locations.
