•

discarding any packaging material. If any parts are missing, do not begin installation

•

until you obtain the missing parts.

Flush the water supply lines before beginning installation and after installation is
complete. Test the unit for leaks and adequate water flow. Main water supply to the
eyewash should be “ON” at all times. Provisions shall be made to prevent unauthorized
shutoff.

The ANSI Z358.1 standard requires an uninterruptible supply of flushing fluid at a
minimum 30 PSI (0.21 MPa) flowing pressure. Flushing fluid should be tepid per ANSI
Z358.1.

The inspection and testing results of this equipment should be recorded weekly to verify
proper operation. This equipment should be inspected annually to ensure compliance
with ANSI Z358.1.

Workers who may come in contact with potentially hazardous materials should be

Installation

IMPORTANT: Power should be supplied
to the alarm by no larger than a 15 amp
branch circuit with a dedicated circuit
breaker or fuse and should not supply
power to any other device. Compliance
and conformity to local codes and
ordinances is the responsibility of the
installer.

Step 1: Install the flow switch in the water
supply line

NOTE: Because the flow switch will attach to the
mounted alarm via a 7-foot waterproof cable, the
installer must keep the location for mounting the
alarm in mind when choosing the flow switch locati­on (see Figure 1).

1. Choose a location for mounting the flow
switch in a horizontal run of the water supply
line. The inlet and outlet ports of the flow
switch must be a minimum of 6 inches from
any tees or elbows in the water supply line
(see Figure 1).

NOTE: If the water supply line will be exposed to
temperatures at or below freezing, the inlet supply
must be freeze-protected 6 inches above the flow
switch tee (freeze protection by others).

(supplied by installer) on all water pipe

NOTE: The alarm system is designed to work proper­ly even if both the eyewash and drench shower are
used simultaneously. The alarm will continue to
operate as long as either the eye wash or drench
shower is still in use.

Step 2: Mount alarm assembly to unit

1. Choose a location for mounting the alarm assembly. The alarm should be mounted at least 7 feet
above ground level for best visibility.

installation is NOT supplied).

Step 3: Make electrical connections—alarm to flow switch

1. Connect the flow switch to the alarm by installing a conduit connector to the end of the 7-foot
waterproof cable and into the flow switch junction box (see Figure 1 on page 4 and Figure 2
below).

NOTE: The cable may be cut to any length required.
NOTE: To prevent water condensation from dripping onto the flow switch, make sure the cable is not

taut.
NOTE: Refer to the instruction manual supplied with the conduit connector for assembly information.

Step 4: Complete electrical supply connections

1. Connect the alarm system to the power source using the shorter length of waterproof cable.

2. Follow the same procedure as in Step

3 for completing the electrical supply connection.

Step 5: Test the alarm system

NOTE: Testing the alarm for the first time using the drench shower may expose the flow switch to an
unnecessary water hammer since the downstream piping may be empty of water. The flow switch is designed to
withstand such a water hammer, but using the smaller eye wash flow is recommended. Refer to Figure 3 when
testing the alarm system.

1. Apply power to the alarm branch circuit. The alarm should remain off.

2. Make sure the alarm horn cut-out switch is in the “ON” position (pull the button out).

3. Open the eye wash valve. The alarm should sound and the strobelight flash shortly after water flows
from the system.

4. Use the alarm horn cut-off switch to silence the horn. Pushing the button should shut off the horn but
allow the strobelight to keep flashing.

5. Shut off the eye wash flow valve. The strobelight should stop flashing.

6. Reset the alarm horn cut-out switch by pulling the button out.

7. Repeat the tests in procedures 1-6 above, this time using the drench shower only.
