Installation
Refer to ZW206 installation instruction and backflow
preventer (975XL2, 375MS) installation instructions for
specific information on these valves during install and
startup.
Flush line to remove all debris before installing any valve.
For ease of repair and maintenance, a shutoff valve
should be installed upstream of the FCIS assembly if one
is not conveniently located nearby.
If a strainer is being installed, it should be located up-
stream of the Model FCIS.
Next the Model ZW206 solenoid control valve with EST
mounted to cover should be installed. Note the direction
of flow arrow on the inlet flange or inlet side of cover.
The backflow preventer is now installed downstream of
the ZW206 and connected to the downstream piping. A
gasket set, nipple or grooved coupling is provided to con-
nect the ZW206 to the backflow preventer.
If necessary, an air gap adapter fitting can be installed to
the relief valve discharge port to direct water to the drain.
A drain MUST be installed in the room to remove dis-
charged water. The Model FCIS will shutdown the water
supply to prevent a catastrophic failure of the backflow
preventer from flooding the room. It will not prevent small
discharges from the relief valve. (A water sensor or float
switch that provides contact closure during flooding can
also shutdown the water if flooding is caused by other
equipment in the mechanical room. Contact factory for
details.)
Start-Up
The solenoid valve, backflow preventer, and water sys-
tem can be filled and leak tested without having to wait
for an electrician to connect power to the EST box.
The solenoid valve is furnished standard as normally
open (NO.) This means the valve will open to allow water

The black wire on the EST should already be connected
to the solenoid pilot. If it not, then the pilot coil should be
plugged into the end of the black cable. The screw in the
center of the plug should be tightened to prevent it from
coming accidentally unplugged.
There is a yellow cable that comes from the EST. This
should be uncoiled and connected to the black socket
on the backflow preventer relief valve located below the
backflow. Line up the keyway in the plug and socket,
then push the plug into place. Next tighten the threaded
lock ring at the end of the cable to the socket to prevent it
from coming unplugged.
flow unless power is applied to the solenoid. A normally
closed (NC) solenoid valve is an option. To determine the
type of valve you have, look at the ZW206 tag on the inlet
flange. NO or NC should appear after the model number.
If you have an NO valve, then the system can be filled by
simply open the shutoff valve upstream of the FCIS.
