Note carefully the flow arrow shown for each type of feeder. The flow in the standard by-pass feeder must be “upward” if a filter bag kit is to be used. The flow on the by-pass feeder with a cartridge filter is “downward.” The filter feeder with bag and basket filter requires “downward” flow. 1. Pipe feeder to cause pressure drop across inlet and outlet resulting in flow through feeder. 2. Provide isolation and drain valves for servicing and draining. 3. Use with hot or cold water only. DO NOT USE FOR STEAM (300 psi @ 200°F max.). 4. Be certain gasket is positioned in groove under cap before replacing cap. (Replace gasket if cap does not seal by hand pressure.) Cap should seal with hand tightening pressure only. Do not strike cap with any tool to seal or unseal. 5. Open valves slowly when returning service. 6. CAUTION! DO NOT OPEN UNDER PRESSURE – close isolation valves and bleed off pressure before opening. 7. CAUTION! CONTENTS MAY BE HOT. 8. CONSULT YOUR CHEMICAL SUPPLIER FOR THE PROPER USE OF THIS TANK WITH THE CHEMICAL. 9. DO NOT COMBINE CHEMICALS IN THIS DISPENSING DEVICE – without specific instructions from your chemical supplier. READ AND FOLLOW LABEL DIRECTIONS FOR THE CHEMICAL IN USE. Standard By-Pass Feeder Refer to installation and operation instructions above. FILTER BAG FILTER BAG KITS INCLUDES: BAG, BAG FRAME, TUBING AND CONNECTORS. HANGER BASE DRAIN VALVE 1. Loosen fitting 1 until the tubing turns in the fitting. GATE VALVE OR ORIFICE BOILER FEED PUMP DRAIN VALVE See instructions for optional filter bag kit at right. INSTALLATION INSTRUCTIONS FOR FILTER BAG KITS 2. Install fitting 1 into the lower side connection of the tank with the end of the tube pointing upward. 3. Retighten fitting 1 to the tubing. Tube should point straight up. The ferrule on the tubing is preset for the tank diameter. 4. Place bag over the hanger wire. Pull the drawstring closed and tie tightly so the bag gathers around the hanger base with the opening of the hanger base protruding from the bag. 5. Insert the bag and hanger base into the tank with the opening of the hanger base pointing downward. The hanger base should engage the tube which is pointing upward and the tubing should fit into the hanger base until the tubing rests against the edges of the wire which protrude into the center of the hanger base. 6. The cap will keep downward force on the wire, keeping the assembly in place.
