The life of a household appliance can be divided into 2 responsible parties, based on the actions of which, depends on the quality, quantity and longevity of the product.
Manufacturer. Manufacture of equipment in accordance with European standards, contract with the world's manufacturing plants, no savings on spare parts and components, the use of modern technology - will make it possible to put on the market a worthy product.
User. Compliance with the proportion in the form of application of rules from the manufacturer that are prescribed in the instructions, the organization of regular support and maintenance, the conditions of product maintenance - will extend the period of use without additional problems.
Let's go into detail.

General recommendations:

1. Selection
An important component - one of the first steps, which will determine the result on the bottom line.
The level of knowledge of engineers directly related to the product will help to select the type of equipment, taking into account all the features of the building, optimal technical solutions and the needs of the customer himself.

2. Installation
The official installation company is the second stage in importance after the choice of air conditioner. Qualification of masters will allow to take into account all peculiarities and nuances, which guarantees long service of the system itself and its correct operation.
Put vibro-supports/vibration absorbers - they will smooth out the noise from the outdoor unit.
Make sure that the installer made a special note of the work in the warranty card.

3. Manual
Unfortunately, for most people, the manual is equated to waste paper not worth attention. However, this opinion is wrong, because it is in the manual that the key information for the user and answers to most of the questions that are formed in cooperation with the manufacturer based on the individual characteristics of the product. We strongly recommend not to neglect studying this document.

4. Temperature range
Familiarize yourself with the operating temperature limits set by the manufacturer. The use of the system, whether domestic or semi-industrial, beyond these limits (each mode is different), is fraught with malfunction or failure.

5. Minimum and maximum
As a rule, the manufacturer gives the minimum and maximum temperature limits. However, engineers do not recommend to go down/up to the limit parameters, as the system works on wear and tear, which reduces its service life and affects the quality of the result.

6. Closed windows
It is important to understand, the air conditioner is a device of local action, when turning it on, close windows and doors. Otherwise, its operation will be useless, as cold/heat will escape and the system itself will go into the enhanced power mode, which entails additional energy consumption, clogging and wear and tear.

Maintenance recommendations:

1. Maintenance
Maintenance (MRO) is a series of activities performed on climate control equipment to prevent breakdowns, malfunctions, and early failure.
The service technician provided by the manufacturer will perform a deep cleaning, error diagnosis, check the Freon level and refill as needed.
It is recommended to perform maintenance 1-2 times a year.

2. Service maintenance
Specialists of the manufacturer's service department are qualified craftsmen who have undergone specialized training on the brands being serviced. We strongly recommend not to use services of third-party services to avoid aggravation of the problem later and to preserve the warranty.

3. Parts and accessories
Use original spare parts and accessories. Any, even the most suitable analog, does not give guarantees on the output, and in some cases - will only worsen the situation.

4. Enclosure
Wash the case with products containing chemical or any other aggressive components in the composition - do not. This will damage the paintwork and the plastic itself, and getting inside the unit will have negative and possibly irreversible consequences.
Use a cloth or soft sponge dampened with running water. For grated surfaces, use soft brushes or cotton swabs.
Never attempt to wash or clean the system from the inside yourself, contact a service center for such measures.
 
We recommend that you carefully read the manual, which contains detailed rules, tips, technical information and features of the equipment.
