ϜFor securely wall mounting it is necessary to determine the type of wall
material (wood, brick, concrete, drywall, and etc.) for corresponding
fastener selection.
ϜMounting stabilizer location should be close to the wall outlet, considering the stabilizer power
cord length.
ϜNext, make a mounting fasteners (not included) to the wall, considering the wall mounting holes

7. INSTALLATION
Attention! Before connecting the regulator, make sure that all consumer devices con-
nected to it are off.
Ϝ Before 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

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!
ϜPlug the stabilizer power cord +in the wall outlet.
ϜTurn on stabilizer with switch *(RESET position).
ϜIf 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 %WXUQVRԚDQG
digital indicator $will show the output voltage of the regulator. And only after that you can turn on
the connected devices, consumers.
ϜWhen 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
ϜThe 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
ϜThe stabilizer is equipped with an circuit overvoltage and undervoltage protection. In the case of

time red LED &illuminates. When the input voltage range returning to 150-270 V the stabilizer
automatically resumes operation.

7KHVZLWFKLVRԚ
2. There is no voltage in the
power supply network.
3. The fuse has activated.
4.The load connected is too
powerful.
The AVR is out of order.
Input voltage is very
unstable.
Input voltage is beyond
possible regulation range of
150 – 270 V.
The AVR does not start.
The AVR is turned on, but
there is no output voltage.
The AVR often produces
clicking sounds.
The AVR has disconnected
the load. Active red indicator.
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.
If the problem is not eliminated,
please address an authorized
service center.
It is normal. The AVR regulates
output voltage.
When input voltage is
normalized, the AVR tuns on
automatically.
CauseProblem Solution
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.
