MS300 Variable Speed Pump
Benefits of operating at low speeds
• Save electricity and money. A reduction in Pump Speed of 50% will reduce power consumption by up to 75%
• Better filtration - the filter can often remove smaller particles when the water moves slower
• Quiet operation, so therefore it is very unlikely to be intrusive to your neighbours
• Reduced Total Dynamic Head - less stress on equipment (e.g. filter) which can extend 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 recomended 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 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 the
individual equipment manuals for specific requirements for low flow operation.
After setting the pump speed(s), it is recommended you check all other equipment/water features are functioning as
intended. For example, when running at low speed for daily filtration, verify that the 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, times of increased bather load, ect.
Filter (LOW Speed) - This speed will meet the daily requirements for most private use pools up to 50,000 litres
depending on the speed it is adjusted too, and will turnover the entire pool volume in an average
8 to 10 hours of operation. The factory default setting of this speed is used to obtain the seven
star energy rating and is the recommended minimum speed for filtration.
Boost (MED Speed) - This speed can be adjusted to increase the flow for the operation of pool accessories or at times of
heavy bather load.
Turbo (HIGH Speed) - Use this speed for backwashing and operation of accessories that may require extra flow for
for specific functions, such as Spa Jets and Water Features.
MS300 Variable Speed Pump
Motor Operation:
1. Power Up
- Via supply cord
- Power LED on / Error LED one or two flashes
- Ramp up (after 5 second delay)
2. Priming Cycle
- Starts on HIGH speed
- Cycle runs for 2 minutes
3. Normal Operation
- Resumes previously selected speed prior to shut down
- LED solidly lit indicating currently selected speed
4. Speed Selection
- Via touch pad on motor interface. One second delay after switching
- Ramp up or down will take 2 - 5 seconds depending on the speed
- LED solidly lit on the newly selected speed
5. Shut Down
- Via power out let that the supply cord is connected to
- Via the STOP button on the motor interface touch pad
6. Fault Mode
- Motor will not start
- Error LED flashes a sequence followed by a pause
- Sequence is repeated (record number of flashes in the sequence and contact your service agent)
7. Over Temperature Mode
- The pump speed is reduced until a steady state temperature is maintained with in the maximum limit
8. Overload Protection Mode
- Speed is reduced until steady state full load current is maintained within the maximum limit
