IMPORTANT SAFETY INSTRUCTIONS

To make the best use of this energy saving device and to avoid potential risk of fire, electrical shock, SERIOUS injury to people or damage to property, please read this user guide carefully before installation and keep it for future reference.

This device can ONLY be used with pool pumps with permanent split capacitor motor. The schematic diagram below shows a typical single speed swimming pool pump motor.

It is NOT compatible with:
a. Single (Three) phase motors with centrifugal switch
b. Pool pump motors with start relays or switch
c. Series or DC motors
d. Pool pump motors with faults in their rotors or capacitors
e. Shaded-pole asynchronous motors

An RCD with a rated residual current not exceeding 30mA must be used with this product.

If you are not sure of the compatibility of your pool pump with this device , please contact your supplier or manufacturer before proceeding with installation.

BEFORE INSTALLATION

Upon receipt of this device, check for damage to the packaging or product.
DO NOT PROCEED with installation if any damage is found; contact your supplier. Do not use extension leads with the device. This can pose a danger particularly in the vicinity of a swimming pool.

Make sure the place you choose for installation meets the following conditions:

• Ambient temperature from -10~40℃
• 45 to 90 percent relative humidity, non-condensing
• Less than 1000m above sea level
• Keep out of direct sunlight
• Good ventilation

For efficient cooling, please make sure it is installed with a minimum clearance surrounding it (Fig.2)
Blocked ventilation or an enclosed space with limited air flow may cause overheating or potential operational failure of the inverter.

CONNECTING TO POOL PUMP

Please follow these steps and the wiring diagram for correct connection. The warranty may be compromised if the device is not installed in accordance with instructions described in this manual.

Only ONE pump can be connected to the inverter. Please do not connect any other appliance to the output.

Mark the hole locations on the wall, drill and insert the expansion plugs supplied, fit the screws and hang the device on the screws.

Turn off all electrical supply to the pool pump, unplug it from the main switch or at the chlorinator which provides electrical power to the pump.
Plug the pool pump into the device’s power outlet (marked PUMP CONNECTION ONLY). It is recommended that the total length of the output cable of the device and the power cable of the pool pump shall not exceed 2m.
Plug the device into the main switch/chlorinator/timer connection where the pump was originally plugged into.
In order to reduce the impact of electromagnetic interference, please connect the grounding wire on the device to the ground terminal of the pool pump motor (It’s not necessary to connect it if there is no plug of the output cable of the device)
Switch all power back on.
Ensure chlorinator/timer is active.
Now the device is ready to operate.

Above figure is for reference only, plug & socket may vary for different countries/regions.

If you do not require a power plug for installation, wire the device as shown in Fig.6 and 7.

Remember to change the motor to 3x230V by changing the steel plates like on the photo.

Do not touch the heat sink while the device is in operation or until at least 30 mins after it has been switched off. Keep it out of reach of children.

Because of high voltage conversion components contained in the device, do not try to disassemble or replace any components in case of malfunction or breakdown. Before serving on the unit, wait till the power light turned off or at least 3 minutes after power plug has been plugged off from input supply.

For iSAVER× 1100C, please connect the pump motor with delta connection.

SETTINGS & OPERATION

Control panel

Mode selection

The frequency inverter has 3 modes (speed ranges). You can either run your pump at a constant speed choosing from “M” or set up to 4 timers for daily operation, each with an individual speed.

1. When plugged in, lights up, hold for 3 seconds to unlock the screen. Press to start.
2. Upon starting, pump will run at maximum speed of 2900 rpm for one-minute self-priming. (This can be increased to 10 minutes – see Parameter settings Section 5.5)
3. Press to choose a running speed, use or arrows to adjust by 50rpm to a specific running
   speed if required.

Once the pump has finished priming, the inverter will automatically switch the pump to the pre-set speed, indicates the pump is running and showing current rpm and power consumption.

Timer setting

To run the pump at a different times or speeds to take advantage of lower electricity tariffs during the night, you can set up to 4 timers.

Step1: Press to enter timer setting.

Step2: Use or to set current time. Press to move cursor to the next setting. Press to choose a speed range for timer 1, use or to decide on a specific speed if required. Press to move cursor to previous setting.

Step3: Repeat the above steps to set the other 3 timers.

Step4: Hold  for 3 seconds or wait 10 seconds to save settings automatically.
A flashing indicates the device is waiting for start time.

Step5: press or to check all 4 timers to ensure there are no invalid setting.

• Any overlapping of timer periods will be considered as invalid and the device will only run based on the previous valid timer setting.
• During timer setting, if you want to abandon it, hold for 3 seconds.

Note:

• If inactivate for 1 minute, the screen will lock automatically. Hold for 3 seconds to unlock the device.
• The device has power-off memory, operation will resume upon power restoration.
• Under OFF mode, hold for 3 seconds to retrieve factory setting

External control (Optional)

External control can be enabled via the following contacts. However, even if it’s working via an external controller, pressing can stop the device.

Please do not apply voltage to these inputs.

E.g.: To enable external speed control via digital input, connect one of the digits from PIN1/3/4 to COM.
When PIN4 connect with Com, the pump will stop; if disconnected, the digital control will be invalid;
When PIN3 connect with Com, the pump will run at 2900 RPM; if disconnected, the control priority will be back on panel control;
When PIN2 connect with Com, the pump will run at 2400 RPM; if disconnected, the control priority will be back on panel control;
When PIN1 connect with Com, the pump will run at 1200 RPM; if disconnected, the control priority will be back on panel control;

Parameter setting

Under OFF mode, hold for 3 seconds to enter parameter settings.

PROTECTION & ERROR CODES

Note:

1. AL01 is not an error indication: when it appears, the inverter will automatically switch to a lower speed to self-protect against high internal temperature. When the temperature drops back to 68℃ the inverter will resume at the preset speed.
2. When causes for E002/E101/E103 lifts, the device will resume working automatically, however when it appears a fourth time, the device will stop working, to resume operation, unplug the device and plug in & restart again.
