Alcowash Operation Procedure¶
First stage displacers are regularly bound with dust and oil contamination that needs to be flushed out in the alcowash process. This process forces alcohol liquid through the displacer to clean out any oil and dust residues.
Fitting the Displacers¶
Each displacer has a specific cylinder that it must run in as well as an o-ring to fit over the top. Please fit each displacer to determine which is the best fit.
RDK Displacers¶
RDK2 Displacers¶
RDK2 displacers require the following materials to function in the cylinder.
- Mounting plate & fasteners
- P70 o-ring
- TS00xxxx slipper seal
- Rising spacer
- Second stage displacer dowel pin
The displacer is assembled with the mounting plate, o-ring, slipper seal, and dowel pin.
Identify the RDK cylinder that the displacer needs to be inserted in.
The rising spacer should already be in the bottom of the cylinder. This holds the displacer above the bottom to allow alcohol to flow freely through the gas passages.
Warning
Without this riser flow of alcohol will be blocked and damage can occur to the alcohol pump.
Insert the displacer top side down into the cylinder by gripping the installed dowel pin and lower it to the bottom until it meets the rising spacer.
Install the P-90 o-ring and fasten the lid onto the cylinder.
Connect the alcohol hose to the lid.
