1. I
NTRODUCTION
This installation manual concerns VRV inverters of the Daikin
RXYQ-P7 series. These units are designed for outdoor installation
and used for cooling and heat pump applications. The RXYQ-P7
series consists of 6 main units and has nominal cooling capacities
ranging from 14.0 to 49 kW and nominal heating capacities ranging
from 16.0 to 56.5 kW.
The RXYQ-P7 units can be combined with Daikin indoor units for air
conditioning purposes, and suitable for R410A.
The present installation manual describes the procedures for
unpacking, installing and connecting the RXYQ-P7 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.

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 R410A 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
R410A does not contain any chlorine, does not
destroy the ozone layer, and does not reduce the
earth's protection against harmful ultraviolet radiation.
R410A 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 R407C
units: 3.3 MPa or 33 bar), pipes of larger wall thickness
may be required. The wall thickness of piping must be
carefully selected, refer to paragraph
"6.2. Selection of
piping material" on page 5 for more details.
