Service steps for the auto drain:
1.
The service of the drain is done with the exhaust manifold remaining connected to the
blocks.
2.
Proceed to disconnect the pilot pressure line from the solenoid valve mounted on
the electrical control box and the drain line from the manifold to the collection
tank.
3.
The Allen bolts (4 to a block) are loosened and removed from the drain assembly
which will provide for the removal of the top manifold exposing the valve pistons
on all drains and also the lower section containing the valve seat assembly.
4.
This leaves the main section of the drain manifold with the block bodies mounted
as a unit; the bodies can be removed to replace o-rings bi-annually.
5.
The seats in the lower bases can be removed and new ones installed with new o-rings.
6.
Push the pistons up and out of the drain bodies for inspection and seal and o-ring
replacement.
7.
Inspect and replace all rubber parts.
8.
Check the pistons for any sign of wear or imperfection on the tapered sealing face,
replace if wear is evident.
9.
After carefully inspecting all components, lubricate the working parts with silicone
lubricant and assemble the drain blocks.
10.
When the automatic drain system is assembled: operate the compressor and check
for leaks.
11.
While the compressor is operating at 90% of the full system operating pressure,
remove the drain hose from the manifold and check that the drain pistons are seated
correctly and there is no sign of leaking air.
