Problem
|
Solution |
| Loss of air in primary air tank |
Check for:
- Bad ground connection
- Bad hot wire connection (must be on 1st pole position of ignition)
- Cut or worn "O" rings on valve body
- Disconnected timer terminal posts
- Cracks or stripped threads on valve body end cap
- Leaks in line from compressor to wet tank
|
| Loss of air in secondary air tank |
Check for:
- Bad one-way check valve between 1st and 2nd air tanks
- Loose air line fittings to air supply line
- Air leak unrelated to ClearDrain
|
| Retention of moisture in air tanks |
Check for:
- Clamped discharge line
- Jammed "O" ring on piston in valve body
- Waterlogged solenoid (due to being plumbed from the bottom instead of the top of the secondary air tank)
- Debris in outlet from wet tank or in discharge line
- Worn solenoid bearing
|
| System purges air at 85-90 PSI |
- Check ground connection, which should not be grounded with any other wire
- Use a star or clip washer to assure a good ground connection
- Spray over connection with silicone
|
System constantly purging
or
System starts to purge after transmission is shifted into neutral or park position
|
- Check for damaged "O" rings - examine bore for metal chips or shavings
- Check that the primary (hot) wire is connected to the first pole position of ignition circuit. Do not connect to battery!
|
|
Water in solenoid
or
Piston will not extend 1" length
|
- Check that the air line to solenoid is plumbed from the top of the secondary air tank
- Re-plumb using a “T” fitting if necessary and connect to Solenoid & allow drying which will occur during the quarter hour purging of ClearDrain System.
- NEVER disassemble solenoid (doing so will void warranty)
|
| Solenoid very hot (burns to touch) |
- Check for burnt bearing in solenoid
|
| Wet tank doesn't drain to 0 PSI at shutdown |
- Check for water in solenoid, ascertain that the solenoid is plumbed from the top of the secondary air tank
- Check that the "O" ring is not defective on piston
|
| System does not pressurize to drive-off capability in 30-40 seconds after starting vehicle |
- An "O" ring may be cut causing air discharge
|
| Air drains from tanks other than the wet tank at ignition shut off |
- Check for defective one-way check valves between the 2nd and 3rd air tanks
|
| System purges intermittently in 10 to 15 second increments instead of a single continuous discharge at ignition shutdown |
- Check for water in the solenoid (due to improper plumbing of the signal line to the solenoid). This component must be replaced.
|
| Solenoid leaks air from weep hole and back of valve body assembly |
- Add 2-3 drops of type F automatic transmission fluid to solenoid
