Service

The SPILLSTOP must be serviced after every pump shutdown before being put back into operation. To service the SPILLSTOP:

1. Disconnect all air supply to the pump and SPILLSTOP. Remove the SPILLSTOP lid and flush internal areas with water or cleaner

appropriate for the process fluid being pumped.

a. Connect an air line to the Regulator and disconnect the plastic tube at Port 2 of the Actuator Valve. Adjust the Regulator to a

minimum of 40 psi (2.7 bar). Air should be flowing from Port 2.

b. Activate the SPILLSTOP by pushing the Float up or raise the Float by turning the SPILLSTOP upside down. Air should stop

flowing from Port 2.

c. If air does not stop flowing from Port 2 when the SPILLSTOP is activated, the Actuator Valve may be clogged or damaged and

should be cleaned or replaced.

2. Reassemble the SPILLSTOP and reconnect the Shutoff Valve(s). Adjust the Regulator to a minimum of 40 psi (2.7 bar) to restart

the pump. If the SPILLSTOP is installed with a Whistle and/or more than two Shutoff Valves, increase pressure to a minimum of 60

psi (4.1 bar).

Maintenance

The SPILLSTOP is normally maintenance free; however, a function test should be performed at least every 90 days to ensure proper

operation. To perform a function test:

1. Turn off all air supply to the pump and SPILLSTOP.

2. Open the Test Port Plug on the SPILLSTOP lid and fill the SPILLSTOP with approximately 2 cups (.47L) of water.

3. Turn on the air supply to the pump and SPILLSTOP, and adjust the Regulator to a minimum of 40 psi (2.7 bar).

The pump should not operate�

4. Turn off all air supply to the pump and replace the Test Port Plug.

5. Drain the water from the SPILLSTOP into an appropriate container by opening the Drain Valve on the bottom of the SPILLSTOP. A

tube or hose should be attached to the Drain Valve when draining fluid.

6. Close the Drain Valve and turn on the air supply to the pump and SPILLSTOP. The pump should operate normally.

Optional Whistle

Connected to the tubing installed on Port 3 of the Actuator Valve, the pneumatic Whistle will sound an auditory alarm alerting personnel

that the primary pump has failed and SPILLSTOP has shut down the pump (Figure 1). When SPILLSTOP triggers a pump shutdown, air

pressure is shifted from Port 2 to Port 3 of the Actuator Valve to pneumatically power the Whistle. The Whistle comes pre-installed from

the factory if ordered with the SPILLSTOP. When ordered separately, the Whistle Kit (part number 50-98K) includes the Whistle, tube

tee and 15 feet of 1/4" tubing. To install the Whistle Kit:

1. Attach the Whistle to the tubing provided and connect to Port 3 of the Actuator Valve. If the SPILLSTOP includes a Pressure

Switch and/or an additional Shutoff Valve for a backup pump, use the tee provided with the Kit to install the Whistle in the tubing

connecting those devices to Port 3. The tee can be inserted at any point in the tubing.

IMPORTANT! The length of tube from the tee to the Whistle must be the same as the length of tube from the tee to the

Pressure Switch and/or the backup pump Shutoff Valve� The Whistle consumes a high volume of compressed air and

if not installed properly, can prevent the Pressure Switch and/or the backup pump Shutoff Valve from activating�

2. Test the Whistle before putting the SPILLSTOP into operation:

a. Connect an air line to the Regulator and adjust the Regulator to a minimum of 40 psi (2.7 bar). If the SPILLSTOP is installed

with more than two Shutoff Valves, increase pressure to a minimum of 60 psi (4.1 bar).

b. Activate the SPILLSTOP by pushing the Float up or raise the Float by turning the SPILLSTOP upside down. Air should start

flowing through the tube connected to Port 3 to sound the Whistle and, if installed, the Pressure Switch should activate.

Optional Pressure Switch

Connected to the tubing installed on Port 3 of the SPILLSTOP Actuator Valve, the pneumatic-to-electric Pressure Switch is used to

power a warning light or other electrical device when the primary pump has failed and SPILLSTOP has shut down the pump (Figure 1).

When SPILLSTOP triggers a pump shutdown, the device connected to the Pressure Switch will be powered on. When the SPILLSTOP

is put back into operation after a pump shutdown, the device will be powered off.

1. The Pressure Switch has three blade-type electrical contact points.

a. Connect the common, usually white wire of the electrical device to the common (COM) blade on the Pressure Switch.

b. Connect the live, usually black wire of the electrical device to the normally open (N.O.) blade connection.

2. Attach the air tube to Port 3 of the Actuator Valve and connect to the Pressure Switch's barb connection.
