Resumen del manual
Determine the correct pump setting from the driller’s record by taking into account the static water level and the drawdown at the proposed pumping rate. Keep the pump at least five feet from the bottom of a drilled well. SPLICING THE POWER CABLE Follow the instructions enclosed in the cable splicing kit you purchase. DROP PIPE Galvanized pipe is recommended for suspending submersible pumps into the well. Plastic pipe may be used only when observing the plastic pipe manufacturer’s recommendations of depth and pressure. Give special consideration to: 1. A safety cable to prevent loss of pump if pipe should break. 2. Torque arrestor just above pump to prevent chafing the cable when pump and pipe twist during the starting and stopping cycle. (See Figure 1) Schedule 40 galvanized pipe is suitable for settings to 600 feet(180m). For deeper settings, use schedule 40 pipe for the bottom 600 feet(180m), and schedule 80 for the remainder. Take great care to keep pipes clean and free from pebbles, scale and thread chips. Make sound, air-tight connections at all fittings. Pipe sealant is recommended. CHECK VALVES Many pumps have a built-in or externally supplied check valve. For a pump without one, install a check valve immediately above the pump. Install an additional check valve above the ground. If the pump is more than 100 feet (30m) below the wellhead, install another check valve in the drop pipe 100 feet (30m) above it. For pump settings deeper than 200 feet (60m), install additional check valves at intervals of 100 feet (30m). REMOVABLE POPPET CHECK VALVE 4” submersible pumps with a 1-1/4” discharge are supplied with a spring-loaded REMOVABLE poppet style check valve assembly. The check valve can be removed from the pump discharge when the pump is installed in applications where drain back is desired. WARNING Fluid draining back through the pump can cause the pump to rotate backwards. If pump/ motor starts during this time; damage to the pump can occur. The check valve can be removed with the use of the T-Handle Poppet Wrench(part no. 23498207). Ordered separately. Or, with standard needle nose pliers. The poppet assembly is left hand threaded and is removed by turning CLOCKWISE. If reinstalling a Popppet Check Valve assembly, the assembly should be tightened to 15 inch-pounds. Poppet Assembly T-Handle Poppet Wrench INSTALLATION OF PUMP, DROP PIPE, AND ASSOCIATED EQUIPMENT Fig. 1 illustrates a typical well installation showing in ground components. Adhere to the following items when installing the pump and drop pipe: 1. Fasten the submersible cable to the drop pipe with clamps or appropriate tape every 10 ft. (3m) to prevent tangling and damage to the cable. The cable must remain slack when using plastic drop pipe to allow for stretching of pipe when installed in the well. 2. Take care not to scrape or pinch the submersible cable against the well casing. 3. Use an ohmmeter or megger to make insulation and continuity checks on the cable once the pump is installed. This locates any fault in the cable. 4. Make sure a check valve is installed immediately above the pump. Install additional check valves at 100’ (30m) intervals. 5. Install a torque arrestor just above the pump to prevent chafing the cable when pump anad pipe twist during starting and stopping. 6. Attach a safety cable to pump to prevent loss of pump if pipe should break. 7. Place a sanitary well seal or pitless adapter with an approved cover plate over top of well per manufacturers recommendations. 8. Keep pump at least 5’ (1.5m) from bottom of well and above well screen or casing perforations. ELECTRICAL INFORMATION 1. Employ a licensed electrician to perform the wiring. All wiring must be done in accordance with applicable national and local electrical codes. 2. Check that the power supply corresponds with the electrical rating of the submersible motor and the control box(if required). Make sure that the control box electrical rating matches the motor electrical rating. 3. Every installation requires a fused disconnect switch or circuit breaker. 4. Every installation must be grounded. There must be a reliable ground connection between the pump and the distribution panel. The motor lead incorporates a green grounding conductor. 5. Lightning arrestors are recommended for every installation. All stainless steel, single phase motors thru 5HP have built-in lightning arrestors. Any 6” motor or 4”, 3-phase motor requires a separate lightning arrestor installed as close to the wellhead as possible. Install the arrestor in accordance with manufacturers recommendations. A lightning arrestor provides protection against induced voltage surges on secondary power lines; it is not effective against direct hits. 6. Mount the control box in an area protected from rain, snow, direct sunlight or other high temperatures as this may cause tripping of the overload protector. Also protect the control box from extreme cold (below 25oF/-32oC) as this may have adverse effect...
