[. . . ] Instruction Manual BL1. 5 - BL3 - BL5 BL7 - BL10 BL15 - BL20 BL7913 - BL7914 Dosing Pumps These Pumps are in Compliance with the CE Directives http://www. hannainst. com Dear Customer, Thank you for choosing a Hanna product. This manual will provide you with the necessary information for a correct use of the pump, as well as a precise idea of its versatility. If you need more technical information, do not hesitate to e-mail us at tech@hannainst. com. These instruments are in compliance with directives EN 50081-1 and EN 50082-1. [. . . ] This makes the unit safer to operate with. · The ambient temperature of the pump, when in operation, should be between 0 and 50°C (32 to 122°F) and should be protected from direct exposure to outdoor elements (direct sunlight, rain, extreme temperatures, high humidity, etc. ). · Generally speaking, the shorter the suction distance, the more efficient the pump operates. · The pump should be placed in a conventional location that will allow easy access to the control and connections. It should be placed so that regular visual inspections of the connections and hoses are facilitated. Injection Point · Choose an injection point that allows you to mount the injection valve assembly vertically. · The spring in the injection valve assembly (HI 721004) adds approximately 1. 5 bar of back pressure. Other Considerations · If you are mounting the system to a wall, column, etc. , be sure it is strong enough to support the weight of the entire system. 20 Vertical Surface Mounting Once you have selected the best installation site, simply screw or bolt the unit into a wall or mounting panel above the chemical feed tank. The 4 mounting screw holes on the pump will accommodate up to a 5 mm (3/16") screw or bolt (remember to use heavy screws or bolts to secure the system). Be sure you do not over tighten and cause excessive stress on the mounting holes. For BL7913 and BL7914 Make sure to leave a slight overhang in front to allow for the connection cable. Electrical Connections Note: All cables must be according to local electrical codes. For safety of the users, the pump has to be grounded. For BlackStone Pumps: The pump should be connected to a single phase power source. 21 Color coding for wires: Blue - Live Brown - Neutral Yellow/Green - Ground (earth) · Remove the protective plastic plate covering the terminals by removing the 2 screws on both sides of the plate.

For BL7913 and BL7914: · Unscrew and remove the transparent front panel cover and gasket seal for access to the terminals. · Remove the cable gland from the hole on the housing below the power terminals (No. · Push a 3-wire power cord through the white gasketed fitting (inside the cable nut), leaving approximately 150mm (5") of cable to work with. · Feed the cord through the hole and connect the cable ends as indicated on the front panel, check the label on the front panel first and connect #1, 2, 4 for a 110V voltage or #1, 3, 4 for a 220V voltage, where: 0 110 115 Black Stone 40 30 20 10 0 50 60 70 80 90 100 FLOW % BL 7914 5 10 IP 54 WITH TRANSPARENT COVER INSTALLED 15 OVERHEATING 2 LITRES/HOUR 0 110 220 115 240 Black Stone 40 30 20 10 0 50 60 70 80 90 100 FLOW % BL 7914 5 10 IP 54 WITH TRANSPARENT COVER INSTALLED 15 OVERHEATING 2 LITRES/HOUR 0 is ground is neutral & 220 240 110 115 220 240 are the live 23 22 terminals. · Slide the fitting up, screw it onto the base and tighten the nut to form the watertight seal. · Replace the transparent cover and gasket seal on the front panel. Permanent Connection using 3/8"PVC pipe UNION CONNECTION All piping for the ADAPTER pump feed and disDISCHARGE VALVE charge should be PUMP plumbed to the loSUCTION VALVE cation of the pump. ADAPTER The threads on both FOOT VALVE valve assemblies - FILTER allow the use of standard 3/8" (Eu- Diagram for Rigid Pipe Hose ropean) pipe fittings for permanent pipe connections. The foot valve assembly (HI 721005) should always hang vertically and not lay horizontal on the bottom of the tank or drum. A vertical assembly will ensure that the valve is positioned properly and prevent loss of prime. standard installations, use PVC adapters to connect the suction and discharge valves to the PVC pipe. Hose Connections · Cut a long enough section of the hose to reach the suc24 tion valve of the pumphead from the feed tank. · Slip a hose connector onto the hose over the head valve and up to the bottom of the threads ensuring it is fully seated. · Slide the connector up to the threads and tighten to form a seal. · Slip the ceramic weight (HI 721008) and a connector over the other end of the hose. · Attach the foot valve assembly (HI 721005) to the hose and slide the connector up to the threads and tighten to form a seal. 25 · Repeat the same installation procedure for the hose connections on the discharge end with the injection assembly (HI721004). Assembling the Hose to the Valve The end of the valve is specially tapered to form a leak free seal when the hose is properly installed. Push the hose until it covers the end of the valve completely. Suction and Discharge Valves The suction and discharge valves located on the pumphead should not be interchanged as they are different internally. [. . . ] Leakage around the pumphead: · Be sure that the valves are tight and o-rings are in place and the head screws (hex bolts) are tight. 35 MAINTENANCE Your BlackStone Pump is designed to give you years of trouble-free service. Maintenance should be the preventative type, that is, periodic cleaning and inspecting for any damage or leakage. Cleaning the Suction, Discharge and Injection Valves Remove the valves from the pumphead, the injection fitting and the feed. Keep the suction and discharge valves separated as they are not interchangeable. After cleaning the glass balls, inspect them for any excessive wear due to abrasion from the chemical. [. . . ]
