Low battery warning?

Or your dead end pressure needs adjusting up.

What controller do you have?

[sandrew]

Variestream

Have you tried turning your shut off psi up? It's also called dead end psi.

If that doesn't stop it then it is signalling your battery is low.

On a Varistream P = shut off pressure has been reached - as per the instructions that came with your controller.

Answer = increase your shut-off pressure. See instructions that come with the unit to do this.

The instructions are also available online in pdf format from Williamson pumps.

This adjustment of shut off pressure seems to be a regular question on this forum. It appears to me that due to the numbers of new posts either posters don't read and/or understand the literature and instructions that come with the equipment or are unable to relate their problem to the same question other posters have asked.

It would be helpful to understand why the O/P came on to the forum to ask the question in view of all the previous postings answering this.

There is another non window cleaning forum I support that bans members from asking the same question that has already been answered if they do this repeatedly. The reason being is that the poster hadn't done a search before hand to find the answer in the previous posts.
