Improper installation will void your warranty. SOLARJACK'S SDS SERIES DC SUBMERSIBLE PUMPS SOLARJACK'S SDS SERIES PUMPS are positive displacement, low voltage, DC powered, submersible pumps. [. . . ] Apply heat until the proper shrinkage is reached. 2. 3f To check proper sealing of the splice and wire installation immerse the splice and wire in a container of water for ten minutes and then take a resistance reading between the water and each of the cable conductors. Connect one ohmmeter lead to the conductor and the other lead to a piece of metal immersed- in the same water. The resistance should be two megohms (2 million ohms) or higher. A lower resistance indicates an insulation leak that must be corrected. 2. 4 CONTROLLER ADJUSTING PROCEDURE NOTE: It is usually not necessary to adjust the controller since it has been pre-adjusted at the factory. 2. 4a This procedure should be performed with the panels at their normal operating temperature at mid-day. To maintain peak output throughout the year, readjust the controller in very hot and very cold weather or as necessary. 2. 4b With the system installed and pumping water, turn the panels away from the sun or cover the panels until the pump flow rate is reduced by approximately 50%. 2. 4c Connect a DC volt-meter to the pump side of the controller. (LD+ and LD-) 2. 4d Turn the "panel voltage adjusting pot", located on the upper left side of the controller, until the highest possible voltage is obtained. (This will also be the highest flow rate). 12/06/99 4 2. 4e Return the panels to their normal position. The pump will then operate at its maximum output. 2. 5 ELECTRODE INSTALLATION (OPTION) 2. 5a With the pump and pipe stretched out on the ground and before installation into the well, (refer to step 2. 1b) cut the electrode wire to the desired lengths and install all three E1-S electrodes in the proper locations. 2. 5b The "ground electrode", terminal 3, must be in the water at all times and should be placed approximately two inches above the top of the pump. The "low water level electrode" terminal 1, is placed at the desired cut off point and is usually placed two to six inches above the ground electrode. The "high water level electrode", terminal 2, is placed at the desired turn-on level, but must be placed below the static water level and should be located no more than 20 feet from the low water electrode. NOTE: Wells with a high mineral content in the water and/or with cascading water above the electrodes may not be suitable for use with the low water cut-off circuit. Mineral deposits may collect on the electrodes insulating the circuits from the water. Section 3 FOR PROPER PUMP PERFORMANCE (Do not disassemble the pump during the warranty period. WARNING: IF THE PUMP IS DISASSEMBLED, USE EXTREME CAUTION AS THE MOTOR HOUSING MAY BE UNDER HIGH PRESSURE. 3. la For optimum pump performance make sure that the wire is sized properly for the length of run between the pump and the panels. [. . . ] 4. lb Check for proper panel, controller, and/or battery voltage with a volt meter. If our pump controller is being used, a quick look at the indicator lights will verify power coming from the panels going to the controller and power coming from the controller going to the pump. If the red light is on and the green light is not, connect a jumper wire across terminals 6 (PV-) and 7 (LD-). This will bypass the controller and will allow the pump to run panel direct. [. . . ]
