Energy Efficiency Overview
The energy consumed by a pump is measured in terms of Watts (W) or Kilowatts (kW). The LifeStar®
Variable Speed Pump 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:
LifeStar® 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 according to the schedule set by the Life Support
Manager. 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.
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. Operate the pump at higher speeds for the shorter periods of time needed to operate a
heater, water feature, etc.

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 the water source 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 indoor or outdoor use, it is advised
to place pump in an outdoor application 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.
