ELECTRIC dRAIN VALVE
PROdUCT dESCRIPTION
The Electric Drain Valve removes condensed water and oil
from the moisture sepearator . Additional drains may be
installed throughout your compressed air system, including
aftercoolers, filters, drip legs and dryers .
The Electric Drain Valve operates on a timer which can be
set to automatically drain the air receiver tank at operator–
determined intervals .
Key features include:
•
100% continuous duty
•
NEMA 4 enclosure
•
Adjustable time on (0 .5 – 10 seconds)
•
Adjustable time off (0 .5 – 45 minutes)
•
Stainless steel operator
•
LED to indicate electrical power is on
•
LED to indicate valve is open
•
Manual override
OPERATION
1 . Open the strainer ball valve .
OPEN
2 . Set the "time off" and "time on" knobs . See TIMER SETTINGS
(below) for an explanation of the settings .
3 . During compressor operation, check for air leaks .
TIMER SETTINGS
The "time off" setting determines the interval between
cycles from 30 seconds to 45 minutes . The "time on"
setting determines the actual time the compressor drains
condensate . The timer's cycle rate and drain opening time
should be adjusted to open just long enough to discharge
the condensate . The timer is properly set when it opens and
discharges condensate and then vents air for approximately
one second before closing . Adjustments may be made
depending on many factors, including humidity and duty
cycle .

MAINTENANCE
Periodically clean the screen inside the valve to keep the
drain functioning at maximum capacity . To do this, perform
the following steps:
1)
lose the strainer ball valve completely to isolate it from
the air receiver tank .
2)
Press the TEST button on the timer to vent the pressure
remaining in the valve . Repeat until all pressure is
removed .
High pressure air can cause injury from flying
debris . Ensure the strainer ball valve is completely
closed and pressure is released from the valve prior
to cleaning .
4)
Remove the plug from the strainer with a suitable
wrench . If you hear air escaping from the cleaning port,
STOP IMMEDIATELY and repeat steps I and 2 .
5)
Remove the stainless steel filter screen and clean it .
Remove any debris that may be in the strainer body
before replacing the filter screen .
6)
Replace plug and tighten with wrench .
7)
When putting the Electric Drain Valve back into service,
press the TEST button to confirm proper function .
Before accessing live electrical parts, disconnect the power
