Thank you for your question, Jason! We would be happy to help. Once the water is on, please turn the diverter handle left or right to turn on the body sprays. Here is a link to the instructions for this model:
Please note that there are a few different versions of the 1800 series. The diverter may simply say "On/Off" or it may have multiple settings to divert flow between the shower head and body sprays (and possibly an additional component).
Best regards, Jon
