Installation

Refer to ZW206 installation instruction and backow

preventer (975XL2, 375MS) installation instructions for

specic 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 up­stream of the Model FCIS.

Next the Model ZW206 solenoid control valve with EST
mounted to cover should be installed. Note the direction
of ow arrow on the inlet ange or inlet side of cover.

The backow 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 backow preventer.

If necessary, an air gap adapter tting 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 dis­charged water. The Model FCIS will shutdown the water
supply to prevent a catastrophic failure of the backow
preventer from ooding the room. It will not prevent small
discharges from the relief valve. (A water sensor or oat
switch that provides contact closure during ooding can
also shutdown the water if ooding is caused by other
equipment in the mechanical room. Contact factory for

details.)

TEST

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 backow preventer relief valve located below the
backow. 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.

Start-up

The solenoid valve, backow preventer, and water sys­tem can be lled 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

WARRANTY: ZURN WILKINS Valves are guaranteed against defects of material or workmanship when used for the services recommended. If
in any recommended service, a defect develops due to material or workmanship, and the device is returned, freight prepaid, to ZURN WILKINS within
12 months from date of purchase, it will be repaired or replaced free of charge. ZURN WILKINS' liability shall be limited to our agreement to repair or
replace the valve only.

ow 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
ange. NO or NC should appear after the model number.
If you have an NO valve, then the system can be lled by
simply open the shutoff valve upstream of the FCIS.

Start-up

®

Fill the system slowly to prevent water hammer, and then
vent any trapped air from the system.
The solenoid valve cover must be vented of air for proper
operation; refer to ZW206 instruction sheet.

There is a red knob on the solenoid pilot. This will al­low the pilot valve of a NO or NC valve to be operated
without power. If your valve is NC, then the solenoid
control valve will prevent water from lling the backow
preventer. Turn the red knob on the solenoid pilot to
manually open the valve and ll the system with water.

Testing Procedures

DANGER!

Death or injury can result if safety precautions are not
followed. There are 120VAC wires and connections lo­cated inside the EST box. Only properly trained person­nel should work near these connections. If all wires are
installed properly, there should be no risk of contact with
energized components. Care should still be exercised.
Do not use any screwdrivers or other un-insulated metal
objects inside the box when the power wires in the box
are energized.

There are three user controls inside the EST box. A
power switch, a delay timer knob and a test switch.
Open the EST box to access these controls.

SET TIMER DELAY

The timer is provided so that nuisance relief valve dis­charges due to water hammer will not cause the system
to shutdown. It should be set so it is long enough for the
valve to re-close if it opens for pressure uctuations. If
it is set too long, then more discharge will occur before
shutdown starts.

If the manual operator has been used on the solenoid
pilot, make sure that it is returned to unscrewed position
for the FCIS to operated properly.

If left for an extended duration in manual override, it

may be wise to hang a note pointing this out to others
who may continue the system startup and testing.

A ½” plugged conduit knockout is located on the bottom
of the EST near the cables. The plug can be removed
to allow 120 VAC power to be connected to terminals
T10, T11 and T12 in the box. Once the power has been
connected to the EST, then proceed to the Testing sec-

tion.

The timer has a range up to 10 minutes, but comes from
the factory set for a 1 second to 60 second range. When
it leaves the factory, the indicator of the timer should be
pointing directly to the left for a 10 second delay.

Turn the POWER switch on. The green power light on
top of the box will light.

If the backow is not pressurized, the monitor switch will
start the timer. If the backow is pressurized, manually
start the timer by pushing and holding the TEST switch
below the timer. A green light on the front of the timer
should come on when it is triggered. You can start count­ing or use a stopwatch to check the timer adjustment. A
red light on the front of the timer and on top of the box
will come on when the timer reaches the end. The so­lenoid coil will also click and hum if it is a normally open
valve. On a normally closed valve, the humming will
stop; a click may not be audible. (When the timer is reset
and the power turned back on, the normally closed valve
should click.) If this time delay does not match your re­quirements, turn the knob and repeat this test. The timer
is reset by turning the power switch off and back on.
(Note: the coil will become hot while it is powered.)
