ϜFor securely wall mounting it is necessary to determine the type of wall material (wood, brick, concrete, drywall, and etc.) for corresponding fastener selection.
ϜMounting stabilizer location should be close to the wall outlet, considering the stabilizer power cord length.
ϜNext, make a mounting fasteners (not included) to the wall, considering the wall mounting holes location ‘ on the stabilizer rear panel (see Fig. 2).

Automatic Voltage Regulator

7. INSTALLATION

Attention! Before connecting the regulator, make sure that all consumer devices connected to it are off.
ϜBefore installing the AVR, please make sure that total power of all voltage consumers is lower than AVR power. Taking into account the starting load and power factor of voltage consumers, it is necessary to apply power margin factor of 1.2–1.5; for such equipment as air conditioners, fridges and other electric motors it should be 1.5–2.
Attention! When choosing an AVR, it is necessary to know that reduction of input voltage
LQFUHDVHVYDOXHRILQSXWFXUUHQWZKLFKPHDQVWKDWPD[LPXPSRZHURI$95LVUHGXFHGWRR
Such dependence is shown in the graph below:

Note. Adhere strictly to such dependence. If the condition stated above is not adhered to, warranty servicing becomes void!
ϜPlug the stabilizer power cord + in the wall outlet.
ϜTurn on stabilizer with switch * (RESET position).
ϜIf the AVR operates properly, green LED # illuminates, and yellow LED % will blink. At the same time the digital indicator ” will show the input voltage. The total delay makes 6 or 180 s depending on the “DELAY” button “RESET/ OFF” ) position. After the delay time yellow LED %WXUQVRԚDQG digital indicator $ will show the output voltage of the regulator. And only after that you can turn on the connected devices, consumers.
ϜWhen the mains voltage exceeds the allowable rate (lower threshold is 150 V, upper threshold is
270 V) the red LED & illuminates, the AVR disconnects the load automatically.
Attention! It is recommended to switch off the AVR and every connected consumer device when the power supply is dropped.

8. PAUSE FUNCTION

ϜThe Pause mode feature is designed to protect equipment in case of frequent drops of the mains supply. This is particularly important for consumer appliances with electric motors or compressors.
After power supply has been recovered, the AVR switches on within 6 or 180 seconds, depending on the ” DELAY ” button ” RESET/ OFF ” position.

9. PROTECTION FUNCTION AGAINST HIGH AND LOW INPUT VOLTAGE, OVERLOAD AND

OVERHEAT
ϜThe stabilizer is equipped with an circuit overvoltage and undervoltage protection. In the case of PDLQVYROWDJHGHYLDWLRQRYHU9RUEHORZ9LW WXUQVRԚ WKHORDGDXWRPDWLFDOO\$W WKHVDPH time red LED & illuminates. When the input voltage range returning to 150-270 V the stabilizer automatically resumes operation.
ϜIn case of overload or short-circuit AVR power switch will triggered. After elimination overload cause or short circuits, press AVR power switch (RESET position), and stabilizer will resume operation.

10. TROUBLESHOOTING

2.      There is no voltage in the power supply network.

3.      The fuse has activated. 4.The load connected is too powerful.

| 1.    Press the switch once again.

2.    Make sure that power supply is available.

3.    Disconnect the AVR from the power supply and reset the circuit breaker

4.    Disconnect some load.

The AVR is turned on, but there is no output voltage.| The AVR is out of order.| If the problem is not eliminated, please address an authorized service center.
The AVR often produces clicking sounds.| Input voltage is very unstable.| It is normal. The AVR regulates output voltage.
The AVR has disconnected the load. Active red indicator.| Input voltage is beyond possible regulation range of 150 – 270 V.| When input voltage is normalized, the AVR tuns on automatically.

If none of the above methods can solve the problem, please seek professional advice at your
nearest service center. Never attempt to repair the product by yourself.
