Household split system Neoclima NS/NU-09EUMIw3 series U-Mate

In accordance with the rules and regulations, the manufacturer specifies two time periods for the product's life, which have different concepts.
Warranty period is a clearly defined period within which the manufacturer undertakes to provide service for warranty episodes.
Service life is a conditional period of time that indicates the duration or time interval of equipment operation. This term is often perceived as a guaranteed period, without taking into account the fact that it depends on the conditions, recommendations and rules prescribed by the manufacturer for its operation and maintenance.
So, let's take it in order.

General recommendations:

1. Installation
An official installation company is the second most important step after choosing an air conditioner. The qualifications of the craftsmen will allow you to take into account all the features and nuances, which guarantees the long service life of the system itself and its correct operation.
Install vibration supports/vibration dampeners - they will smooth out the noise from the outdoor unit.
Make sure that the installer makes a special note of his work in the warranty card.

2. Temperature operation
Check the operating temperature limits set by the manufacturer. Using the split system outside these limits (each mode has its own) is fraught with malfunctions or breakdowns.
For example, a standard air conditioner with an inverter compressor can operate down to minus 15C outside. At temperatures below this value, the system should not be turned on. If your city has a climate with harsh winters, we recommend considering a split system with a built-in winter kit or the possibility of installing it on your current equipment.

3. Minimum and maximum
As a rule, the manufacturer gives the minimum and maximum limits of the temperature range. However, engineers do not recommend going 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.

4. Closed windows
It is important to understand that the air conditioner is a localized device, so when you turn it on, close the windows and doors. Otherwise, its operation will be useless, as the cold/heat will disappear, and the system itself will switch to the high power mode, which entails additional energy consumption, clogging and wear.

Care recommendations:

1. Maintenance
Maintenance is a series of actions in relation to the split system in order to prevent possible malfunctions, incorrect operation and failure before the time.
A service technician provided by the manufacturer will perform a deep cleaning, diagnose errors, check the freon level and recharge if necessary.
It is recommended to carry out maintenance 2 times a year with intensive use in the off-season, summer and winter. 1 time per year - for occasional use.

2. After-sales service
The manufacturer's service specialists are qualified craftsmen who have undergone specialized training on the brands served. We strongly recommend that you do not use third-party services to avoid worsening the problem over time and to preserve the warranty.

3. Spare parts and accessories
Use original spare parts and accessories. Any, even a suitable analog, does not provide guarantees on the output, and in some cases will only worsen the situation.

4. Filter
It is recommended to clean the coarse filter (flat, mesh plate under the top cover of the indoor unit) using either dry (vacuuming with a vacuum cleaner) or wet (washing under running water and drying) methods.

5. The casing
Do not clean the casing with products containing chemical or any other aggressive components. This will damage the coloring and damage the plastic itself, and getting inside the air conditioner will cause negative and possibly irreversible consequences.
Use a cloth dampened with running water or a soft sponge. For grated surfaces, use soft brushes or cotton swabs.
In no case do not try to wash or clean the split system from the inside by yourself, contact a service center for such activities.

We recommend that you carefully read the manual, which contains detailed rules, tips, technical information and features of the split system.
