Series DV is an automatic drain system designed to eliminate the need
to manually drain water and harmful sediments from your compressed air
system, thereby improving the systems performance. The unit can be
used on receivers, dryers, tanks, and drop legs for sampling and purging
a wide variety of liquids. The Series DV has a heavy-duty motor for
operation under adverse conditions and an adjustable timer to meet
specific user requirements. By design, the Series DV eliminates major
drawbacks of other compressed air draining systems. The valve is brass
for corrosion resistance and it is a full port ball valve giving maximum and
unobstructed flow with no clogging. A test button allows for the unit to be
cycled at any time. It is mountable in any position for easy plumbing, and
trouble free operation.
Do not apply electrical power to the unit unless the unit is fully assembled
and mounted. Failure to do so could result in personal injury and/or
damage to the unit. Disconnect power source and depressurize the
system before working on the unit. Failure to do so could result in
personal injury. The downstream or discharge side of the ball valve must
be directed to a safe area for collecting water, oil and debris. The
compressed air system is pressurized during operation. Appropriate
precautions are recommended.
CAUTION: It is recommended that eye protection be worn while
servicing the system. Failure to do so could result in personal injury.
WARNING: The motorized drive unit case is not capable of supporting
any loads. Do not attempt to use the unit as a step. This will cause
damage to the unit and could cause personal injury. Do not use in
hazardous locations.
CAUTION: Do not use the case as leverage when mounting this unit or
tightening fittings. Use the wrenching flats on the valve body.
