MG-3/AST4 Installation
212/10/07 Bradley Corporation • 215-1323 Rev. P; EN 07-814
IMPORTANT!
Read this entire installation manual to ensure proper installation. For optional
soap dispenser, refer to Installation Instructions for Express®Lavatory System
MG-Series document 215-1585. 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.
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.
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
completed. After installation is complete, turn on the water supply first, then turn
on the electrical power.
Hardware supplied by installer must be appropriate for wall construction. Wall
anchors used must have a minimum pull-out rating of 1,000 lbs. Overtightening
fasteners can damage the Terreon®material. Use caution when tightening bowl and
sprayhead fasteners.
Product warranties may be found under “Product Information” on our web site at

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.
Loosen, but do not
remove the bottom
access panel screws.
ARemove the top access panel
screws and washers and
remove the access panel.
B
Once you have positioned
the frame such that it is level
and flat against the wall or
shimmed, use the 3/8" bolts
and washers (6 places) to
mount the frame to the wall.
C
Secure the bowl to the wall
anchors with two 3/8" bolts and
washers. Do not overtighten.
B
Attach the bowl to the frame using the
four 1/4-20 x 1/2" pan-head screws and
washers. Do not tighten screws.
A
Tighten the pan-head screws. Do not overtighten.
If necessary, adjust the sprayhead body to fit
closely to the wall by adjusting the sprayhead
mounting bolts. Refer to the components
illustration for bolt locations.

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 (5) 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).
When removing screws, the housing assembly will drop down.
If the housing, piston and spring are not held together, the piston will pop out of the housing.
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.
For ease of insertion, hold the pushbutton housing so the piston is facing the rear of the unit.
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.
