FMMASO-91S Overfill Warning Valve <br /> Installation& Maintenance Instructions <br /> The FMMASO-91S Overfill Waning Valve(OW V)is used to shut offthe air supply to the pump when the <br /> tank approaches full capacity.When the OW V shuts off air to the pump,air is diverted to a whistle mounted on <br /> the unit to signal an alert that the tank is full.The OW V is automatically reset when the tank is emptied and air <br /> pressure in the OW V is zero. <br /> Specifications <br /> Air Inlet............................................................ 14'Female N.P.T. <br /> Air Outlet........................................................ 14'Female N.P.T. <br /> Signal Port..................................................... 1/9'Female N.P.T. <br /> Mounting............................................................... 2"MaIeN.P.T. <br /> MmmumAir Pressure....................................................100 PSI <br /> Air Flow Capacity.......................................... 20 CFM @ 100 PSI <br /> Operating Temperaft............................................10-to 185°F <br /> Weight...................................................................................2 lbs <br /> General Requirements <br /> The following safety precautions need to be observed before operating the unit: <br /> 1.DO NOT exceed the pressure rating of my component in the system. <br /> 2.Read all instruction sheets,and any other explanatory material before anempting to operate,assemble,or <br /> disassemble the system. <br /> 3.Protect all material and air supply lines from puncture or damage.Especially be aware ofplaces where lines <br /> or hoses may be damaged when flexing or twisting,or by hot machinery or moving parts. <br /> 4.All lines should be inspected daily forweak or wan condition prior to work operations. <br /> 5.Disconnect air and material supply lines and relieve pressure prim to removing or servicing my component <br /> in the systen. <br /> Caution:The Overfill Waning Valve is not intended to reduce or replace user responsibility when transferring <br /> liquids to a tank. <br /> Attention:La soupape d'avertissement de remplissage excessif <br /> West pas cmKue afin de diminuer on de remplacer la responsabilite <br /> de I'utilisateur Ims du transfer[de liquide dans un reservoir. <br /> When the OW V slam is sounded,the pump harnsfering <br /> liquid to the tank must be turned off immediately to <br /> prevempossible overfill oftank <br /> Installation � <br /> Note.Reduce air pressure in airline to zero prior to li - <br /> connecting the Overfill Waning Valve. <br /> 1.
