Always refer to hardware <br />manufacturer’s specifications for weight capacity and usage. <br />ATTACHING THE DRIP TRAY <br />(1) Use screws provided in accessory kit to secure drip tray to bottom of proportioner. <br />(2) Attach a length of 1/4" tubing to drip tray for draining liquids. <br />(3) Divert drain tube to sink, drain, or five gallon holding jug. <br />CONNECTING THE WATER SUPPLY <br />This proportioner operates best with a flowing water pressure of 30 - 40 PSI. <br />Fluctuating pressure can affect dilution ratios — use a water source that is not feeding <br />other equipment whenever possible. Water temperature should be between 40ºF and <br />180ºF. <br />(1) Attach male connector on high pressure supply hose to inlet side of proportioner <br />using garden hose washer. <br />(2) Attach female connector on high pressure hose to water source. <br />(3) Turn on water and check for possible leaks. <br />IMPORTANT NOTE: <br />If proportioner is connected to a janitor’s sink <br />with an atmospheric vacuum breaker, a <br />special connection kit is required by A.S.S.E. <br />specification 1055. Failure to use this kit, or <br />equivalent connection means, will invalidate <br />the A.S.S.E. and I.A.P.M.O. (UPC) <br />certification. Specify P/N 7600187 when <br />ordering the kit. <br />MXC-400 SERIES <br />MIXING CENTERS <br />FOR DRYWALL SURFACE <br />WASHER <br />TOGGLE <br />BOLT <br />SIDE VIEW <br />Figure 1 <br />FOR CINDER BLOCK & CONCRETE <br />SIDE VIEW <br />MASONRY <br />SCREW <br />Figure 2 <br />ITEM #15 <br />MXC-404
