Yes. Please see additional supplement Notes below.

Is there a warranty or guarantee on the life span of this product?
Yes: see the Warranty Card when you purchase it. There is a 1-year warranty from defects. The lifespan of the Power.Tune is between 5-7 years.

How do I use it?
For a premise with a single phase wired system, simply plug the PT-01 device into any available 13 Amps 3-pin plug. The 13 Amp power-point must be a original dedicated power point. Sharing with an adapter is not allowed. A temporary Extension Power point hook to a multiple extension socket is not allowed. There is no necessity to plug it as near to the Meter as possible. Leave it switched on. If you want to disconnect the device from the power point, switch off the switch at the power point and wait for 10 seconds before disconnecting the 3 pin plug to allow for power to dissipate. (There is power in the capacitor) 

For a premise with a 3 phase wired system, consult a qualified electrician or consult the Seller of the Device. You can identify the 3 phase system by the red, blue and yellow power cables entering the meter. You will need to identify which phase carries the highest current and connect the PT-02 into the respective 13 Amps socket.

It can be use in a Single Phase wired building. What about in 3 phase buildings?
Yes, it can be use in a 3 phase wired building as well. See Instructions on how to install it above.

How many percent of savings can I expect from using this device?
Between 10% to 30 % and more depending on various factors.

Is there any maintenance required on this product?
No, this Device is maintenance free. There are no moving parts, it is not classed as an electrical appliance. Simply plug it into any 13 Amps socket and its done.

What are the limitations on the use of the Power.Tune?
This Device can be used in Shops, Home, Office, Restaurants, etc. However it is not designed for loads in heavy duty settings. For Loads above 6000Kwh, please consult us accordingly for further needful actions.

The following tips are helpful in determining why there is no reduction in the cost of the electric bills after installing the device for at least a month.

1. Apparent non-reduction of the electric bill after one month of use. This happens when the Utility monthly bills is an estimated bill instead of actual metered bill.
2. The Power.Tune having been installed, has been left switched off after the power point has been used for other appliances.
3. The device has been installed mid way after the reading of the previous bill or just before the next bill and so does not show a reduction when the bill comes. Too short a period to see the difference.
4. Users electric power usage is not typical or consistent. Eg. Periods of heavy electrical usage fluctuating with periods of very low electrical usage. There is no constant pattern of use. This does not mean that the Power.Tune is not working. An accurate way to judge this situation is to compare the actual bills and average them over 3 months to get a pattern of average monthly consumption and compare it with the preceding 3 months before installation of the Power.Tune.
5. Additional equipment is installed by the User after the Power.Tune Device has been installed. This in effect increases the electrical consumption of the premise over and above what the Power.Tune was originally designed for.
6. User does not install the recommended number of units of Power.Tune calculated according to their monthly consumption, either due to lack of available power-points or installation of additional power-consuming appliances. The Power.Tune is stretched to its limits and cannot perform efficiently.
7. The same situation applies to a premise with 3 phase electrical wiring system. There are insufficient power-points to install the recommended number of devices to optimize the savings (i.e. install a lesser quantity than the recommended units). Each unit of the PT-02 can handle a monthly maximum load not exceeding 2000 KWH x 3 phase (6000KWH) and if a household's electrical load exceeds it, 2 units should be installed per phase or else the results will not show a reduction in power consumed as the device is overworked. Eg. instead of installing 2 units recommended per phase, (2 for each phase), Owner only installs one unit in each of the 3 phase. Example, a customer merely installs 1 unit in a 3 phase wired building. The other 2 phases are not covered by the Power.Tune, hence the Power.Tune does not seem to work.
8. Savings will be substantial on appliances with inductive loads (motor-related appliances like Air Cons, Freezers, fridge, Fans etc ). Savings will be less on heating elements.
9. The conditions of the household appliances also affect the performances of the Power.Tune. Well maintained appliances certainly cost less to operate (energy efficient) and if after installation of the device, owners neglect to continue maintaining the appliances (eg. Air-cons, servicing the filters, condensers, heat exchangers at the due intervals), this will make the electrical appliances work harder, hence increasing your electrical bill.
10. Ambient temperature also has an effect on the performance of the device. On hotter days, the air con will use more energy to cool the rooms and so the device while reducing the cost of the bills will have to work on higher parameters of ambient temperatures and extra load. This will tend to give an "apparent" indication that the device does not work. 

Some air-cons are set on manual High cooling rate all the time and this will also result in apparent in-effectiveness of the Power.Tune.

Working Principles

All electrical supply is subject to surges from time to time, which result in spikes or parasitic peaks that cannot be used by your appliances as working power. These spikes simply consume electricity to no benefit. Worse still, they result in overheating, which shortens the life your appliances and wiring, and in extreme cases can cause burns, blow outs and power cuts.

The Power.Tune uses a capacitor system to stabilize the flow of electricity. It reduces the spikes in the supply, protecting against surges. The system improves the power factor of your electricity and reduces your electricity bill by on average 15%-20%.

The Power.Tune will work on the whole circuit in your building (Single Phase). Field testing for a typical home consistently shows that the Power Saver will save 3 to 4 kw per day, based on electrical consumption of 30 kw per day. The amount of savings depends on a few factors, such as the types of electrical appliances, the time they are in use and the location. Places near to shops, restaurants and light industries, where the voltage supply is unstable and fluctuating will see higher savings. Where voltage supply is particularly unstable, the Power.Tune can reduce electrical consumption by 30% or more.

Power.Tune reduces the reactive power generated by inductive loads. It extends the life span of an appliance’s motor, and helps the utility companies by eliminating interference to the power supply.

Power.Tune also improves safety by reducing the overheating of electrical wiring. This in effect can lead to reduction in the size of wiring and copper loss. The Power.Tune also extends the life span of your electrical appliances. The Power.Tune is certified for compliance with CE standards. The Device is able to store electricity for 5 to 10 seconds and release it for use during downside voltage.

Technical Aspects

There are two components of power: reactive power and working (real) power.

• Reactive power (kVAR) is used to create EMF in the inductive loads in your home
  and business. This power performs no "real" work.
• Working power (kW) is the power that performs the function of the load, i.e. turns the
  drive shaft.

These two components combine to formulate Apparent Power (kVA), the total power which the load consumes. Apparent power is equal to the square root of kW2 + kVAR2

Power Factor is the ratio of working power (kW) to apparent power (kVA). In other words, looking at all the power that a load consumes, how much of it (percentage wise) is used to perform the real work. A higher Power Factor means the electrical appliance is more efficient and consumes less electricity. The Power.Tune increases the Power Factor of an electrical appliance.

The Power.Tune improves the power factor by reducing the amount of reactive power (kVAR) that the load draws from the utility company. This is accomplished by supplying the reactive power locally at the load by the use of
capacitors. Capacitors store the reactive power (kVAR) needed for the creation of the EMF within the inductive load. As the motor operates, this reactive power is "pulled" and "pushed" to and from the capacitors by the motor. In simpler terms, it can said that inductive receivers (motors, transformers, etc) consume reactive energy, while capacitor (capacitive receivers) produce reactive energy. Therefore the amount of reactive power purchased from the utility company by a power factor optimization has been greatly reduced, or eliminated by use of the Power.Tune.
