1.0 DESCRIPTION OF NORMAL OPERATION:

1.1 This product consists of a quarter turn ball valve mated to an electric actuator with a fully adjustable timer controller. The product is designed for mounting in a pipe-line requiring adjustable set closed times and adjustable set open times. A common application is draining fluids from compressed air system components such as separators, filters, airlines and receiver tanks. The timer is set at the factory to open the valve for 10 seconds every 2 hrs.

2.0 INSTALLATION INSTRUCTIONS: (Reference Figure 2)

2.1 Carefully unpack the valve from its shipping box or boxes. Check for visible signs of damage immediately file a claim with the carrier if damage is found. Do not install a damaged valve or actuator. Note: 2” valves and larger will be shipped in two boxes, one containing the valve and one containing the actuator. Smaller valves are shipped with actuator installed.

2.2 2” valves and larger will require installing the actuator after installing the valve in the line (See Figure 3).

2.3 Make sure that all pressure is removed from the line where the valve is to be installed. Make precautions to ensure the line remains free of pressure during the installation process.

2.4 Check the line for obstructions and clean as required.

2.5 Make sure all components and parts you are installing meet the temperature and pressure ratings of your system. (piping, manual valves, fittings, or electrical parts are not included)

2.6 Install a tee onto the line with the outlet facing down. Install a nipple and manual ball valve on the tee facing down. This is for bypassing the timer valve if it is not operational for any reason.

2.7 Install an isolation valve on the remaining opening. Close both manual valves and install a nipple and union on the isolation valve.

2.8 Install the valve after the union and install all additional piping downstream of the valve and bypass valve per your local requirements.

2.9 Locate a suitable power source and verify it meets the requirements of your valve (see valve label). Wire the valve using the cord included or conduit taking all precautions necessary to meet all required electrical codes for your location. Verify your timer valve is in the closed position and that timing is per your needs.

2.10 Review steps 2.1 through 2.9 to verify no steps were skipped.

2.11 Slowly pressurize the system. Once the system is fully pressurized, slowly open the isolation valve and check the system for leaks. In the event a leak is discovered, remove pressure from the system and repair before proceeding.

2.12 Your valve is now installed and ready for operation.

FIGURE 2 RECOMMENDED INSTALLATION

CAUTION: DO NOT INSTALL MORE THAN ONE FLOW SOURCE PER VALVE. MULTIPLE SOURCES WILL HAVE V ARIED

PRESSURES RESULTING IN HIGHEST T O LOWEST CONTAMINATION.

FIGURE 3 ASSEMBLY OF ACTUATOR AND VALVE (2” AND LARGER)

3.0 ADJUSTING THE TIMER

3.1 The time between drain periods and drain periods are adjusted by a dipswitch keyboard located on the circuit board inside the cover. Remove power from the unit and then unscrew the (4) screws holding the cover in place. Take caution not to stress the wire harness connecting the bottom board to the top board.

3.2 Adjust per the chart in Figure 4. Note: The timer settings cannot be changed unless power is removed from

the unit.

3.3 Reassemble cover making sure that the cover o-ring seal is properly seated and the wire harness is not positioned near the motor.

3.4 Apply power to the unit and push the TEST button to clear the previous setting.

FIGURE 4

CAUTION

POWER MUST BE REMOVED FROM UNIT WHEN CHANGING SETTINGS.

TEST BUTTON MUST BE USED ONCE AFTER POWER IS RESTORED TO INITIALIZE NEW SETTINGS.

Page 4

4.0 PUSH TO TEST BUTTON

4.1 Must be pressed after timer change to initialize new setting.

4.2 If depressed and released, the valve will cycle one time.

4.3 If depressed and held, the valve will stay open until released.

5.0 REQUIRED MAINTENANCE Periodically check the valve for the following:

5.1 Press the Push to Test button to verify valve rotation. Valve should rotate back to closed position.

5.2 Check actuator to valve connection area for debris which could impede proper operation.

5.3 Check wires and/or electrical connections for signs of damage.

5.4 Check valve for leaks. If leaks are present, remove pressure from the system and replace the ball valve.

5.5 Check fasteners for tightness.

Note: Service work to be done by qualified personnel only! Always remove pressure and power from the unit before servicing.

If this is not the problem, replace the entire unit. If the motor will not turn after power is applied directly to it, the motor has failed and the unit must be replaced.

150,000 cycles (will vary with application). Free valve of any debris. If valve is damaged, replace.

Valve will continue on set time once power is restored from the point power was interrupted.

Remove power and adjust timer to desired settings. See SE C TION 3.0
