NOTE: This unit may be mounted in any position with

the flow in either direction. For air receiver applications,

(Figure 2) it is recommended copper tubing be used

for all connection on the pressure side of the valve.

For drop leg applications, (Figure 3) install ridged tubing

or pipe from the valve to the lowest practical point

of your system.

WARNING:

Always disconnect power source before

working on this unit. Failure to do so could result in

personal injury. The valve is under pressure. Discharge

of compressed gas or fluids will occur during any cycling

of the ball valve when unit is installed in the piping system.

Eye protection is recommended.

Operation

Plug the power adapter into a proper power source. The unit will initiate a discharge cycle and

the timing sequence will begin. The "DISCHARGE" button may be used to cycle the valve at

any time, without disrupting the timing sequence.

If an electrical outlet isn't available, the transformer plug may be cut off to wire direct to 12

VDC power. DO NOT EXCEED input voltage range of 10 to 14 VDC.

To change the timing sequence: First choose the required frequency of operation from the

chart on the face label. There are two columns on the chart. The activated column is designated

by the lighted arrow at the top. Scroll, using the "SELECT TIME CYCLE" button, until the code

number shows on the display and the activated columns match your desired setting.

Maintenance

Periodic maintenance is recommended to ensure long, dependable service from your drain

valve. Check power cord for breaks in the outer jacket or damage to the plug. The case should

be kept clean so that label instructions are legible. The ball valve should be checked for leakage

at the downstream side.
