About the product
The iSAVER+ swimming pool pump frequency inverter is designed to allow the user to control and vary the operational speed of the
swimming pool pump in order to gain energy and cost saving efficiencies.
The product benefits from multiple time and speed settings, which can be used manually or automated through timers. The easy to
read display shows current operational settings and also provides power usage information for the setting in use.
Two models are available: DVSD03 (Inverter output 1.1kW) for pumps up to 1HP, and DVSD04 (Inverter output 2.2kW) for pumps
up to 2HP – ENSURE YOU ARE USING THE CORRECT MODEL.
WARNING This device is designed for use ONLY with swimming pool pumps with a permanent split
capacitor motor. Fig 1 below shows a wiring schematic for a typical single speed swimming pool pump motor

Locating the device
The choice of location for the device must meet the following condition:
• Indoors
• Ambient temperature of -10 to +40°C
• Less than 1000m above sea level
• Out of direct sunlight
• Good ventilation (see below)
For efficient cooling, ensure the unit is installed with a minimum clearance
around it of 40cm above and below and 25cm at either side, as per Fig 2.
WARNING Blocked ventilation or an enclosed space with
limited air flow may cause overheating or potential operational failure
of the inverter.
Connecting to the pump
NOTICE Please follow these instructions for pump connection. Incorrect connection will void the warranty.
WARNING Only ONE swimming pool pump can be connected to this device – do not attempt to connect
multiple devices. Do not connect anything other than a swimming pool pump to the output of this device.
Using the template supplied, mark hole locations on the wall where the inverter is to be mounted. Drill holes and use the plugs and
fixings supplied to create the mounting position for the unit. Test mount and then remove.
From the rear of the inverter, remove the recessed screws which hold the outer cover to the body. Carefully lift and remove the outer
cover in order to gain access to the internal terminal connections.
WARNING A qualified electrician must carry out all electrical wiring in accordance with local electrical
regulations.
If currently installed, turn off the full electrical supply to the
swimming pool pump. Unwire the pump and make a connection,
through the cable glands, to the correct terminals within the
inverter as shown in Fig. 3. Ensure all terminal connections are
well made and tight.
Connect the pre-wired power cord from the inverter to the
power source, via and RCD with a rated residual current no
exceeding 30Ma (this will very probably be the power source
that the pump was originally connected to).
Carefully reconnect the outer cover of the inverter and mount
it onto the fixing screws. The electrical supply can now be
reinstated and the inverter is ready for use.

Pre-set modes
The iSaver+ includes three pre-set modes (speed ranges) as shown in the table below. The pool pump can be run at a constant
speed by choosing one of these modes via the ‘M’ function, or it can be run via the setting up of four timers for daily operation, each
with an individual speed.
Mode (M) Speed Range Default Speed
Night (slow) 1200-1650rpm 1400rpm
Day (medium) 1700-2400rpm 2000rpm
Backwash (high) 2450-2900rpm 2900rpm
Useful notes on general operation
If inactive for 1 minute, the screen will lock automatically. Hold for 3 seconds to unlock the device.
The device has a ‘power off memory’. In the event of power interruptions settings will be retained and resume upon power
restoration.
To restore factory settings, with the unit OFF, hold together for 3 seconds.

Initial operation
When first powered up, will illuminate. Hold for 3 seconds in order to unlock the screen.
Press to start the inverter.
Upon starting, the pump will run at maximum speed of 2900rpm for one minute in order to ensure priming. This can be increased to
up to 10 minutes if required – see ‘Parameter Settings’ on page 8.
Press to choose a running speed. Use the and buttons to adjust the speed in 50rpm increments in order to set a specific
running speed if required.
Once the pump has finished priming, the inverter will automatically adjust the pump speed to the pre-set value.
shows that the pump is running and at which current speed (rpm). Power consumption in Watts (W) is shown for that
particular speed.
Timer setting
Running the pump at different speeds at different times of the day will minimise energy consumption when higher speeds are not
needed and can allow the user to take advantage of lower electricity tariffs, for example during the night.
In order to benefit from this, the iSaver+ allows the setting of up to 4 timers. These are established as follows.
Step 1: Press to begin using the timer function
Step 2: Use and to set the current clock time.
Step 3: Press to toggle to timer 1 and use and to set the start times for that timer. Use to toggle to the stop times,
use and to set that time. Use to toggle to the speed setting.
Note: Each setting is saved as you ‘toggle’ through with the button.
Step 4: When the time is set, press to choose a pre-set speed range for that timer 1, or use and to decide on a specific
speed if required.
NOTE: Pressing together will move the cursor to the previous setting.
Step 5: Repeat steps 3 and 4 to set the remaining times.
Step 6: Hold for 3 seconds, or wait 10 seconds to save the timer settings automatically.
NOTE: When is flashing, this means that the device is waiting for a start time.
Step 7: Press or to check all 4 timers and ensure there are no invalid settings. Any overlapping of timer periods will be
considered as invalid and the device will only run based on the previous valid timer setting.
NOTE: During timer setting, if you want to abandon the process, hold for 3 seconds.
