1. INTRODUCTION
This installation manual concerns VRV inverters of the Daikin
RX(Y)Q-M9 series. These units are designed for outdoor installation
and used for cooling and heatpump applications. The RXQ-M9-series
consist of 3 main stand-alone units and has nominal cooling
capacities ranging from 14.0 to 28.0 kW. The RXYQ-M9-series can
be combined from 6 main units and has nominal capacities ranging
from 14.0 to 135 kW and nominal heating capacities ranging from
16.0 to 150 kW.
The RX(Y)Q-M9 units can be combined with Daikin VRV
indoor
units for air conditioning purposes, and suitable for R-410A.
The present installation manual describes the procedures for
unpacking, installing and connecting the RX(Y)Q-M9 units.
Installation of the indoor units is not described in this manual. Always
refer to the installation manual supplied with these units for their
installation.
1.1. Combination
The indoor units can be installed in the following range.
Always use appropriate indoor units compatible with R-410A.
To learn which models of indoor units are compatible with
R-410A, refer to the product catalogs.
Pay attention when connecting outdoor units in multi
combination. RXYQ-M units are NOT compatible with RXYQ-M9
units.

Installation manual
READ THIS MANUAL ATTENTIVELY BEFORE STARTING
UP THE UNIT. DO NOT THROW IT AWAY. KEEP IT IN
YOUR FILES FOR FUTURE REFERENCE.
IMPROPER INSTALLATION OR ATTACHMENT OF
EQUIPMENT OR ACCESSORIES COULD RESULT IN
ELECTRIC SHOCK, SHORT-CIRCUIT, LEAKS, FIRE OR
OTHER DAMAGE TO THE EQUIPMENT. BE SURE ONLY
TO USE ACCESSORIES MADE BY DAIKIN WHICH ARE
SPECIFICALLY DESIGNED FOR USE WITH THE
EQUIPMENT AND HAVE THEM INSTALLED BY A
PROFESSIONAL.
DAIKIN EQUIPMENT IS DESIGNED FOR COMFORT
APPLICATIONS. FOR USE IN OTHER APPLICATIONS,
PLEASE CONTACT YOUR LOCAL DAIKIN DEALER.
IF UNSURE OF INSTALLATION PROCEDURES OR USE,
ALWAYS CONTACT YOUR DEALER FOR ADVICE AND
INFORMATION.
THIS AIR CONDITIONER COMES UNDER THE TERM
"APPLIANCES NOT ACCESSIBLE TO THE GENERAL
PUBLIC".
The refrigerant R-410A requires strict cautions for keeping
the system clean, dry and tight.
Clean and dry
Foreign materials (including mineral oils such as
SUNISO oil or moisture) should be prevented from
getting mixed into the system.
Tight
R-410A does not contain any chlorine, does not
destroy the ozone layer, and does not reduce the
earth's protection against harmful ultraviolet radiation.
R-410A can contribute slightly to the greenhouse
effect if it is released. Therefore we should take
special attention to check the tightness of the
installation.
Read "6. Refrigerant piping" on page 4 carefully and follow
these procedures correctly.
Since design pressure is 4.0 MPa or 40 bar (for R-407C
units: 3.3 MPa or 33 bar), pipes of larger wall thickness may
be required. Refer to paragraph "6.1. Selection of piping
material" on page 4.
