Davey PowerMaster ECO-SERIES - Manual (Page 3)

3
The PowerMaster ® ECO Series has 3 speeds, so you can circulate the
water at low speed, then switch to medium or high speed only if required.
Medium speed will help to power an automatic pool cleaner, while high
speed should be selected to backwash a media filter or when you want to
manually vacuum your pool.
What to expect with low speed pumping (energy efficient operation) on
your pool:
If your PowerMaster ® ECO-Series pump is replacing a traditional AC motor
pump, you will need to run it longer than your old fixed speed pump. This is
NORMAL and you will save energy when using Mid or Eco Flow settings.
You may also notice that the pressure gauge on your filter is indicating
a much lower pressure than you are used to. This is also NORMAL. The
lower system pressure is simply a result of the lower speed and flow rate
produced by the pump.
While running at the lower speed settings you will also notice a significant
reduction in pump noise. This is a major benefit for you as it allows you to
run your pump during off peak electricity tariffs, which will also assist in the
reduction of your operating costs. Plus you will also have much happier
neighbours.
Important Considerations for Low Flow Operations:
Many pool products rely on particular minimum flow rates for best operation
and/or efficiency. If you are using a low flow pump on your pool, such as the
PowerMaster
® ECO Series pool pump, Davey recommends that you check
the compatibility of it with other pool equipment such as:
• Automatic pool cleaners
• Ozone generators
• Pool Heaters
• Solar Heating systems
• Salt Water Chlorinator cells
