1. Remove the red scolding ring from the cartridge.

2. Using the Athena handle or pliers, turn the brass top counter-clockwise until it stops. This indicates maximum hot water flow. 2.1. Underneath the cartridge, a chamber will allow for maximum hot water flow. 2.2. By turning the knob back towards the right, you can reduce the amount of hot water flow (see provided pictures).

3. The red scolding ring and white plastic on the cartridge have two inner grooves, with one slightly smaller than the other. 3.1. When reinstalling the red scolding ring, align the small groove on the ring with the small white plastic groove on the cartridge. This prevents any further hot water flow beyond the desired setting.
