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 fl uids from compressed air system components
such as separators, fi lters, 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 fi le 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, fi ttings, 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.
