LG Air Conditioners and Energy Solutions is a division of LG Electronics that specializes in the manufacture and sale of air conditioning and air purification systems for both
private and industrial applications. The division also produces energy-saving products: solar panels and lighting systems, as well as the «smart home» system.
The production of the first LG air conditioners was opened in 1968, when the company still bore the name Gold Star. Subsequently, some products were developed with the support of specialists from
General Electric Corporation.
The air conditioning unit was originally part of the LG Digital Appliance. In 2009, it was singled out as an independent unit of LG AE Company. The company has appointed six regional leaders for
Europe, the CIS countries, the Middle East, Asia, Central and South America and China. To date, production has been established in China, South Korea, Turkey, Thailand, India, Saudi Arabia,
Brazil and Vietnam. For the Russian Federation, systems are delivered from factories in China, South Korea, Turkey and Thailand.
- 1968 — the first GoldStar window-type air conditioner was launched.
- 1985 — the first GoldStar inverter split system in South Korea was announced
- 2001 — the world’s first design air conditioner ARTCOOL was launched
- 2004 — the company is the first in the world to cross the line of 10 million air conditioners produced
- 2008 — the company was the first in the world to cross the line of 100,000,000 manufactured air conditioners and is the absolute leader in sales of household split systems.

Какую информацию можно найти в сервис мануале (инструкции)
Сервис мануал (инструкция) содержит в себе информацию, относящуюся к обслуживанию и мелкому ремонту того или иного оборудования. Как правило, Вы получаете сервис мануал для Вашего устройства при его покупке. Кроме того, на сегодняшний день существует множество Интернет ресурсов, предоставляющих инструкции для устройств различных моделей и марок. -

Что такое схемы?
Схемы и схематические диаграммы являются неотъемлемой частью электротехнической промышленности, так как они представляют собой наглядное описание конструкций тех или иных устройств. Схемы необходимы для обслуживания и ремонта различного оборудования и электромеханических систем. -

Использование руководств (инструкций) по ремонту.
Руководства (инструкции) по ремонту для того или иного устройства обычно выпускаются независимыми издательствами, не имеющими отношения к официальным производителям оборудования. Это не те инструкции, которые изначально поставляются вместе с приобретаемой техникой. Хотя в целом информация, содержащаяся в руководствах по ремонту, схожа с той, которую можно найти в обычной инструкции, между данными документами есть явные различия. Дело в том, что руководства по ремонту обеспечивают нас более детальной, полной и специфичной информацией.
