InSinkErator Model WX-300 Owners Manual - Page 11

Plumbing Connections WASTE OUTLET LINE Connect a 2" drain line to the Waste Xpress waste outlet as specified per local codes (see Figure 18 for water outlet location). InSinkErator recommends that the water outlet empties into a floor drain. If the water outlet connection on the Waste Xpress needs to be switched to the other side, complete the following: • Remove the four screws holding the cap and gasket in position (see Figure 18). • Install gasket, cap and inlet fitting on reverse side and secure with appropriate screws. NOTE: The Waste Xpress system should not be plumbed directly into a small inside grease trap. The unit can be plumbed through a large exterior grease trap. PLUMBING CONNECTIONS The syphon breaker is supplied with all Waste Xpress systems (packed separately). Syphon breaker must be installed above the sink flood plane per local plumbing codes. Check direction of water flow arrows. The solenoid valve is supplied with a 24 V coil. • The flow control valve regulates all cold water flowing into the disposer and Waste Xpress. This conserves water and prevents overloading. WATER SUPPLY CONNECTIONS When connecting the incoming water supply to the disposer, sink bowl and Waste Xpress, use as few elbows and tees as possible. All cold water line fittings are 1/2" NPT except the sink bowl nozzles which are 1/2" compression. Use 1/2" compression fitting to connect hot water to Waste Xpress. Install the flow control valve, water solenoid valve, and syphon breaker according to the direction of the arrows marked on each valve body. NOTE: In-line hot and cold shutoff valves are recommended close to the Waste Xpress system for ease of service. ROUTING WATER FLOW Connect cold water only to disposer, bowl, or trough. Connect hot water only to Waste Xpress for hot water spray nozzles. In a trough system, route all water flow to the end of the trough to flush food waste. PROPERTY DAMAGE System has hot water spray that must be connected. Fresh water connection to the Waste Xpress must be hot water only. Failure to use hot water may clog system and result in malfunction.
