Pressure Washers

Detergent Mixing: Husqvarna 3100psi Pressure Washer

When I add detergent, bleach, or other chemicals to the detergent container and use the black spray tip to apply, my question is this:

At what ratio does the pressure washer mix water with the solution in the detergent container?   For example, if I add pure bleach, does the PW mix 1/1 (one part water to one part bleach); 2/1 (two parts water to one part bleach); 10/1 (ten parts water to one part bleach); etc?  I could not find this info in the manual or anywhere on-line.  Many thanks.
