3. Energy Efficiency Overview The energy consumed by a pool pump is measured in terms of Watts (W) or Kilowatts (kW). The 2.70 THP variable speed pump family displays power consumption in Watts. Given this information, you can determine the cost of operating the pump: Power consumption of pump X Cost of electricity = Cost of Pump Operation per Hour Example: Hayward variable speed pump operating at 300 W. Cost of electricity = $0.10 per kWh Convert Watts to Kilowatts: 300 W = 0.3 kW 0.3 kW X $0.10/kWh = $0.03 per hour Note the power consumption is greatly affected by the speed of the pump. Lowering the speed of the pump can drastically reduce the power that is consumed. Below are some of the major benefits of running the pump at lower speeds. Benefits of running at low speeds  Save electricity and money  Improved filtration - the filter can often remove smaller particles when the water moves slower  Quiet operation  Reduced Total Dynamic Head - less stress on equipment (e.g. filter) which can lengthen equipment life When determining the speed(s) to operate your pump, you must also take into account the minimum requirements for proper sanitation and equipment/water feature functionality. It is recommended you filter ("turnover") all the water in the pool at least once every 24 hours. Check with local requirements for the minimum turnover rate. Running the pump at a lower speed may require running the pump for a longer period of time in order to meet the turnover requirements for proper sanitation. Equipment such as heaters, skimmers, and chlorinators require minimum flows to operate correctly. Refer to individual equipment manuals for specific flow requirements. After setting the pump speed(s), it is recommended you check that all other equipment/water features are functioning as intended. For example, when running at a low speed for daily filtration, verify water is adequately flowing over the skimmer weirs. Operate the pump at higher speeds for the shorter periods of time needed to operate a heater, water feature, etc. 4. Installation and Wiring WARNING - This product should be installed and serviced only by a qualified professional. 4.1. Pump Location Locate pump as close to pool as practical and run suction lines as direct as possible to reduce friction loss. Suction lines should have continuous slope upward from lowest point in line. Joints must be tight (but not over-tightened). Suction line diameter must equal or be larger than the discharge line diameter. Though the pump is designed for outdoor use, it is advised to place pump and filter in the shade to shield them from continuous direct heat. Select a well-drained area that will not flood when it rains. Do NOT install pump and filter in a damp or non-ventilated location. Keep motor clean. Pump motors require free circulation of air for cooling. Page 8 of 36 USE ONLY HAYWARD GENUINE REPLACEMENT PARTS 2.70 THP VS Pump Family IS3206VSP3 Rev-B
