1.3.3 This unit has ventilation grills. Ensure that sufficient ventilation is provided. DO NOT block the
ventilation grills. Install this unit at least 20 cm. from the wall to the side of the unit for good ventilation
and at least 30 cm. from the wall to the back of the unit for easy access when maintenance or repair.
1.3.4 Use insulated tools to reduce your risk of electric shock.
1.3.5 Remove all jewelry or other metal objects such as rings, necklace, bracelets and watches when
installing this product.
1.3.6 Place the AVR on reinforced cement floor which can carry its weight.
1.3.7 Connect the cables to the terminals of this unit as mentioned in the diagram and installation procedure
to prevent the damages.
1.3.8 Turn off the AVR by turning off the INPUT breaker before connect any cables to the computer.
1.3.9 To prevent surge, always turn on the AVR before turn on the equipments.
1.3.10To connect the AVR to AC source, it is recommended to connect through MDB (Main Distribution Board).
1.3.11 During heavy rain and storm, it is recommended to stop using any equipment including the AVR to
prevent them from lightning through AC Line.
