The Portability Kit includes 4 casters, faucet adapter & Y-connector to make your machine portable and able to connect to a single sink faucet. The 4 casters replace the legs on the appliance to make your machine portable. Simply screw the casters into the holes below each corner of the machine. Each caster has a locking lever, which locks the appliance in place once it has been moved to the desired position. This safety feature prevents the machine from moving or rolling around. The Faucet Adapter Kit includes a snap-on snap-off 2-part faucet adapter and a Y-connector. Part A of the faucet adapter easily connects to a single sink faucet and can remain connected. Part B connects to Part A and to the Y-connector. The 2 split ends of the Y-connector allow connection to hot water and cold water hoses which attach to the washing machine. The snap-on snap-off feature of the faucet adapter allows for a quick one step process to connect the water supply from the sink faucet to the washing machine. Once the washing machine has completed the laundry cycle, Part B along with Y-connector and hoses can be easily snapped off and removed from the sink faucet. Part A remains on the faucet for use when it’s the next time to use the washing machine.
