Please read this instruction manual carefully before using the pump. 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. [. . . ] self-priming height 1. 5 m (5') 0 to 50°C (32 to 122°F) 95% R. H. Dimensions for Installation BlackStone Pumps are designed for permanent installation. 18 19 The pump can be mounted directly on a wall or tank (see pages 12-17 for the specific mounting dimensions). Power Requirements BlackStone pumps are designed to operate to specifications within the following voltage ranges: 100 - 130 Volts for 115V models 200 - 240 Volts for 220V models To ensure maximum performance, check the voltage at the point of supply to verify that it is sufficient. It is recommended that you install a 1 Amp circuit breaker between the pump and the power supply. This will give additional protection to the internal circuit and provide a convenient way to disconnect the power supply prior to servicing the pump, if needed. Inside BL7913 and BL7914, for increased safety, the incoming voltage of either 115 or 240V is reduced to 12V by an isolated transformer. With a maximum voltage of 12V and with the transparent cover installed, risk of electrical problems is minimized. 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. If pumping into a high back pressure, the spring should be removed. 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.

[. . . ] Replace if necessary with parts from HI 721102, HI 721103, HI 721104 and HI721105 (see page 40 for listing). When reinstalling the valves into the pumphead, tighten by hand first and then with a wrench ¼ to ½ turn. Inspecting the hose (if used as supplied with the pump) Inspect to see if the hose has worn out or weakened due to the chemicals. Pay particular attention for any signs of abrasion or discoloration.
