EDUS39-606A-N Installation
Installation of Outdoor Units 11
If the conventional refrigerant and refrigerator oil are mixed
in the R-410A, the refrigerant may deteriorated.
• Never perform outdoor unit piping connection work
when it is raining.
• The PCI Data Station is a class A product. In a domestic
environment this product may cause radio interference in
which case the user may be required to take adequate
measures.
4.2 Introduction
4.2.1 Combination
• Always use an appropriate indoor unit compatible with R-
410A.
To learn which models of indoor units are compatible with
R-410A, refer to the product catalogs.
• Total capacity/quantity of indoor units
<Outdoor unit> <Total capacity of indoor units> <Total quantity of indoor units>
RXYMQ36MVJU.... 18~46.8 6 units
RXYMQ48MVJU.... 24~62.4 8 units
4.2.2 Standard operation limit
The figures below assume following operating conditions for
indoor and outdoor units:
Equivalent pipe length ................25 ft. (7.6 m)
Level difference...........................0 ft.

Optional accessories
To install the above outdoor units, use the following optional
parts:
• Refrigerant branching kit*
NOTE: Systems using R-410A must have the appropriate
kit designed for that system.

- Or the weight in lb of the refrigerant gas in 1f 29
- Refrigerant gas is heavier than air and replaces oxygen a massive leak could lead to oxygen depletion especially in basements and an asphyxiation hazard could occur lead ing to serious injury or death 29
- The installer and system specialist must follow proce dures to prevent leakage according to local regulations or standards the following standards may be applicable if local regulations are not available 29
- The vrv system like other air conditioning systems uses r 410a which is an entirely safe non toxic non combustible refrigerant nevertheless care must be taken to ensure that air conditioning facilities are installed in rooms large enough to ensure that in the unlikely event of a major leak the maxi mum concentration level of refrigerant gas is not exceeded maximum concentration level the maximum charge of refrigerant and the calculation of the maximum concentration of refrigerant is directly related to the humanly occupied space in to which it could leak the unit of measurement of the concentration is lb f 29
