Troubleshooting Chart - DynaQuip Controls DRAINMASTER Manual De Instrucciones

1. Install the automatic drain valve to the compressed air
system at a point where moisture would tend to collect.
2. Pipe the opposite end of the valve to our discharge area.
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
Set the dial at the desired frequency of operation. Plug the cord set into a proper power source. The
valve will cycle and the timing sequence will begin. To change the timing sequence, simply change
the code setting and the timer will reset. The test button may be used to cycle the unit at any time.
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.
