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 VARIED
PRESSURES RESULTING IN HIGHEST TO LOWEST CONTAMINATION.

3.0 ADJUSTING THE TIMER
3.1 Refer to FIGURE 1 for button description
3.2 Firmly push the mode key and up arrow key simultaneously and hold for a full 3 seconds. The display will
change to allow adjustment to the valve closed and open times.
3.3 Use the up or down arrow keys to set the hours you wish the valve to remain closed. Press the enter key. Use
the up and down arrow keys to select the minutes you wish the valve to remain closed. Press the enter key. Use
the up or down arrow key to set the minutes you wish the valve to remain open. Press the enter key. Us the up or
down arrow key to set the seconds you wish the valve to remain open. Press the enter key. Your timer is now set.
4.0 REQUIRED MAINTENANCE
Periodically check the valve for the following:
4.1 Press and hold the Mode and Enter key for 3 seconds to verify valve rotation. The display should say “OVER-
RIDE” and the valve should rotate from closed to open and back to closed.
4.2 Check actuator to valve connection area for debris which could impede proper operation.
4.3 Check wires and/or electrical connections for signs of damage.
4.4 Check valve for leaks. If leaks are present, remove pressure from the system and replace the ball valve.
4.5 Check fasteners for tightness.

TROUBLE SHOOTING
PROBLEM CAUSES SOLUTION
Unit will not operate (No
display on LCD) No power Check power supply. Check circuit breakers or fuses. Check to see if circuit has a
remote power on/off switch.
Fuse F1 is blown Replace Fuse F1.
Unit will not operate (“VALVE
FAULT” displayed on LCD)
The control board did
not sense that the
next position, closed
or open, was reached
for a period of 15
seconds
Turn power off and back on. Press and hold Mode and Enter buttons simultaneously
for 3 seconds. If “OVERRIDE” is displayed but valve does not rotate, fuse labeled F2
on bottom board is blown. Replace fuse. If “OVERRIDE” is displayed, valve rotates
continuously and valve fault reappears, then optic sensor has failed. Contact factory.
If “OVERRIDE” is displayed, valve rotates and the timer closed time appears, then the
“VALVE FAULT” has been cleared.
Unit will not operate (LCD
display working properly)
Faulty actuator/motor/
valve assembly
Press and hold the Enter and Mode keys simultaneously for 3 seconds. If the actuator
motor turns but the valve does not, check for a broken or loose valve stem. If the stem is
broken, replace the valve. 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.
Valve binds during rotation Ball valve seats worn Replace the ball valve.
Ball valve ball clogged
or damaged Free valve of any debris. If valve is damaged, replace.
Ball valve leaks prematurely
Defective ball valve Replace ball valve.
Valve set on short
cycle time
Ball valve should be replaced at some time between 100,000 and 150,000 cycles (will
vary with application). If cycle times are set below 5 minutes, then the ball valve will
most likely require replacing within the warranty period (based on 24-hour per day
operation). This is considered normal wear and not covered under warranty.
Display reads “OPEN” or
“CLOSED” and valve is in
the opposite position Power Interruption Press and hold the Enter and Mode keys simultaneously for 3 seconds. Valve will
rotate to the closed position.
