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.

WARNING This device IS NOT COMPATIBLE WITH:

• a) Single phase motors with centrifugal switch
• b) Motors with start relays or switches
• c) Series or DC motors
• d) Motors with faults in their rotors or capacitors
• e) Shaded-pole asynchronous motors

WARNING An RCD with a rated residual current not exceeding 30Ma must be used with this device.
If you are unsure of the compatibility of your swimming pool pump with this device, please contact your pump supplier before proceeding.

List of supplied components

• iSaver+ inverter
• Power supply cable (pre-wired into inverter)
• Mounting template, fixings screws and plugs

Installation

WARNING Upon receipt of this device, check for any damage which may have occurred in transit. If any damage is found, DO NOT PROCEED WITH INSTALLATION and contact your supplier for advice.
WARNING Do not power this device by means of an extension lead.
WARNING A qualified electrician must carry out all electrical wiring in accordance with local electrical regulations.

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.

Settings & operation

CAUTION Do not touch the heat sink whilst the device is operating, or until 30 minute after the device has been switched off. It is normal for the heat sink to get hot during standard operation.

Display control panel contents

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.

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.

1. Step 1: Press ****to begin using the timer function

2. Step 2: Use and to set the current clock time.

3. 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.

4. 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.

5. Step 5: Repeat steps 3 and 4 to set the remaining times.

6. 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.

7. 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.

External control
External control can be enabled via the contact shown in Fig. 5 below. However, even if the device is working via an external controller, pressing **can stop the device.
For example – to enable external speed control via digital input, connect one of the digits from Di2/3/4 to COM
NOTICE** Do not apply voltage to these input contacts.

Parameter settings
When turned OFF, hold ****for 3 seconds to enter parameter settings.

Maintenance

This device carries no serviceable or maintenance needing parts. In the event of a fault or failure which cannot be resolved via these instructions, please contact your supplier.
WARNING Because of high voltage conversion components contained within this device, do not try to disassemble the device or replace any components in the event of a malfunction or failure.
WARNING Before disconnecting the device from mains power, always wait until the power light has turned off OR wait at least three minutes after power has been disconnected – whichever is the longer.

Troubleshooting / protection & error codes

The device may show error codes in certain circumstances – these codes could signify a fault, or may be an alert to protect the device form damage.

Note 1: When the cause resulting in error code E002/E101/E103 lifts, the device will resume working correctly – however this pattern will only repeat for three occasions – on the fourth occasion the device will stop working. To resume operation, turn off all power, then re-establish power and re-start the unit. If problems persist contact your supplier for assistance.
Note 2: AL01 is not an error indication. When this code appears, the device will automatically switch to a lower speed to selfprotect against internal high temperatures. When the temperature drops back to 65°C the inverter will resume at the pre-set speed.
