Floor-to-ceiling inverter air conditioner NCSI24EH1z/NUI24EH1z

The operation of the purchased appliance largely depends on the quality of its manufacture by the manufacturer, the user himself, his compliance with the rules and regulations established by the manufacturer.
Warranty and operating period are two different concepts that should not be confused, where: warranty period - the period when a breakdown (see the list in the instructions) or factory defect is eliminated by the manufacturer's service center on a free basis; operating period - a period of time for which a particular device is designed, provided that the user adheres to the established recommendations from the factory and the representative of the particular equipment.
More details below.

General recommendations:

1. Selection
An important component is one of the first steps that will determine the bottom line result.
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 step in importance after the choice of equipment. The qualification of masters will allow to take into account all the features and nuances, which guarantees a long service of the system itself and its correct operation.
Put vibro-supports / vibration absorbers - they will smooth out the noise from the operation of 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 a paper not worth attention. However, this opinion is wrong, because the manual contains key information for the user and answers to most questions, which 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. Starting the system outside these limits (each mode is different) may result in malfunction or failure.

5. Minimum and maximum
As a rule, the manufacturer gives 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 or more often (depending on the type and frequency of operation of the unit itself).

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 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. Filter
It is recommended that the system be cleaned through the manufacturer's service department.
For do-it-yourself cleaning, please read the instructions carefully.
Before any manipulation inside the system, it must be de-energized. After opening the air intake grille, act strictly according to the rules specified in the instructions.
The filter can be cleaned with a vacuum cleaner, brushes, water or a mild detergent solution. Wipe/dry dry in a cool place. Do not expose to direct sunlight or contact near fire.

5. Enclosure
The hull must not be washed with detergents containing chemicals or any other aggressive ingredients. Doing so 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.
