The Swash 1200 requires an electrical outlet, operating on a standard 120-volt AC. You will need a 3-prong GFCI grounded outlet (an outlet with an internal safety breaker, common in kitchens and bathrooms). If your outlet is more than 3.5’ from your toilet, you will need a grounded extension cord to operate your unit. For those customers interested in installing a new outlet specifically for the Swash 1200, the optimum location when facing your toilet fixture is to the right side of the fixture underneath the toilet tank. For additional information, please see the "Installation" tab on each product page.
