13. INSTALATION MANUAL
Models: NeoRé 8, 11, 14, 16 (HP)
For authorized person
This sign informs about the most important information such a protection against the danger
DANGEROUS
of electric shock, injury caused by leaking refrigerant etc.
This sign informs about important information about safe run of the device.
WARNING
ATTENTION This sign informs about information to which you should pay attention.
Inside and outside unit have to be disconnect from electrical network before any manipulation with electric device.
After disconnection is necessary to wait at least 5 minutes until capacitors of the electric circuit are discharged.
This air conditioner uses new refrigerant HFC (R410A).
The instalation of the device is the same like instalation of devices with R22, R407, R134 refrigerant etc.
It´s necessary to keep these rules:
1 The pressure is about 1,6x higher than pressure with convectional refrigerants. Therefore is necessary to use
special instruments and measure equipment. It´s necessary to use copper pipeline with homologation for R410A
refrigerant for connection of inside and outside unit. If you work with refrigeration technology, you should
use protective equipment such as glasses, gloves etc.
2 This device with R410A refrigerant uses different service connection from convection refrigerants, which prevents
against connection of unapproved service tool. The connection for R410A refrigerant is 1/2 UNF (standard R410
accessories).
3 Don´t use pipeline which was used with another refrigerant or lubricating oil. The pipeline must be extremely clean
and dry. Storage and transportation of pipeline must be in closed state.
4 Filling and exchange of refrigerant must be in liquid state when the refrigerant is stable and both parts are added in
the correct ratio. The R410A refrigerant consists of two parts.
Special tool for R410A refrigerant

Manometers
Service hose
Vacuum pump
Leak detector
Copper pipeline
This device contains new HFC refrigerant (R410A)
The pressure is 1,6x higher. Using of these manometers for convection refrigerants may lead to their
destruction. These manometers have also different connection.
Service hose must be specially designed for R410A refrigerant.
It´s used convection vacuum pump with adapter for connecting to R410A refrigerant.
Leak detector must be homologated for R410A refrigerant.
