STEP 20: PREPARE FILL FUSER FOR VALVE INSERTION IMPOATAIiT. inspect the riser Alpe for any f oreign material over sprayfrom tank relining or any internal burrs inside of pipe must be removed prior to Installa- tion. Failure to have an unobstructed riser pipe may prevent proper insolation or operation of the valve. Thoroughly clean top of rises pipe. STEP 21: RFJAOVf ELAS'f1C8ANp Remove the elastic band securing the float to the valve body. The float wilt move into an outward position. STEP Z2.
