shipping box). Center wax ring over Hopper
Flange. Turn Microflush Marine Head over, lift
up, and center it with the horn of the wax ring into
standard floor flange located on centerline 12"
from wall. Compress the wax ring by applying
weight to your Microflush Marine Head. A second
standard wax ring may be added if floor is uneven.
If Hopper Flange hits floor flange, grind it down
for added clearance, as any contact will break seal
between Hopper and Toilet Bowl, causing leaking.
All Rear Discharge Models
: Install inverted
P-Trap supplied with Microflush Marine Head. Do
not glue or connect fittings until fitting alignment
has been checked.
Caution:
Outlet of LF-210 and LF-219 Models is
3/4" off centerline. Make sure head discharge and
waste line are in line, not off set.
When using a 1-1/2" discharge line, a vertical lift
of 36 inches can be achieved in single head
applications. The vertical rise must be at the toilet.
This vertical application is not advised for
commercial, high use applications. Do not use the
P-Trap with a vertical rising waste line. Please
contact the factory for further information.
LF-219 Model
: For downward discharge, use
molded P-Trap hose supplied. For rear discharge
use inverted P-Trap. See page 9 for part numbers.
Remote Models:
Position and mount the Remote
Valve Assembly making sure the Vacuum Breaker
is at least 6" above the rim of the Microflush
Marine Head bowl. Measure air and water lines to
make sure Remote Valve is mounted within
connection distance to Microflush Marine Head.
Run water and the three air lines from the Remote
Valve Assembly to Microflush.
Caution
: For Remote Flush Activators, make sure
inside wall thickness does not exceed 1/2" or large
mounting nut will restrict movement of flush

Microflush through wall access (maximum 7
feet).
4 Position toilet and connect hopper discharge
outlet to waste line.
5 Bolt toilet to floor and attach back plate to wall.
Do not reposition toilet after it is connected to
the waste line as this may break the seal between
bowl and Hopper and cause a water leak.
Re-install side panels on toilet.
