FAQ
What is the TD Series Timer Drain?
The TD Series is an automatic condensate drain designed for compressors, air dryers, and receiver tanks. It combines a solenoid valve, ball valve strainer, and electronic timer to discharge condensate at set intervals.
What voltages are available?
The TD Series is available in multiple voltages including 12VDC, 110–120VAC, and 220–240VAC (including 240V models not shown in some literature). All models operate the same way; only the power supply differs.
How does the timer drain work?
The timer controls two settings. The interval time determines how often the drain opens, adjustable from 0.5 to 45 minutes. The discharge time determines how long the valve stays open, adjustable from 0.5 to 10 seconds.
At each interval, the solenoid valve opens and discharges condensate automatically.
Where should the TD Series be installed?
The TD Series should be installed at a low point where condensate collects. Common applications include air compressors, air dryers, receiver tanks, and filters or separators.
Why is my timer drain not working?
If the drain is not operating, common causes include lack of power or incorrect voltage, incorrect wiring or reversed polarity (especially on 12VDC models), a faulty timer module, or a clogged strainer or blocked discharge line.
The solenoid works when bypassed, but the timer does not. What does this mean?
This typically indicates that the valve and coil are functioning properly. The issue is most likely related to the timer module, wiring, or power supply.
How do I troubleshoot a TD Series timer drain?
Start by pressing the test button on the timer. If the drain actuates, this confirms power is reaching the unit. Next, verify the correct voltage is present at the timer and that it remains stable under load. Check all wiring connections and confirm correct polarity for DC units. Inspect the strainer and ensure the discharge line is not blocked.
What should I do if the unit still does not work?
If the drain still does not function after troubleshooting, provide a picture and a short video of the installation. This helps verify wiring and application conditions. If the unit is confirmed defective, it may be eligible for warranty replacement.
What are the key specifications?
The TD Series features an interval time range of 0.5 to 45 minutes and a discharge time range of 0.5 to 10 seconds. Typical connection size is 1/4 inch NPT, and the unit includes an integrated strainer and valve assembly.
What makes the TD Series a good choice?
The TD Series offers low cost, reliable operation, and high performance automatic condensate removal.
