clean the venturi with a pipe cleaner or similar article, which may eliminate any cycling problems.

2. Unplug the connector block to the pressure switch. Refer to fig. 6.
3. Remove the two tubes from the pressure switch outlets.
4. Undo and remove the retaining nuts holding the pressure switch in place.
