Caution
READ THIS MANUAL ATTENTIVELY BEFORE STARTING UP
THE UNIT. DO NOT THROW IT AWAY. KEEP IT IN YOUR
FILES FOR FUTURE REFERENCE.
Caution
IMPROPER INSTALLATION OR ATTACHMENT OF EQUIP-
MENT OR ACCESSORIES COULD RESULT IN ELECTRIC
SHOCK, SHORT-CIRCUIT, LEAKS, FIRE OR OTHER DAM-
AGE TO THE EQUIPMENT. BE SURE ONLY TO USE ACCES-
SORIES MADE BY DAIKIN WHICH ARE SPECIFICALLY
DESIGNED FOR USE WITH THE EQUIPMENT AND HAVE
THEM INSTALLED BY A PROFESSIONAL.
IF UNSURE OF INSTALLATION PROCEDURES OR USE,
ALWAYS CONTACT YOUR DAIKIN DEALER FOR ADVICE
AND INFORMATION.
Caution
The refrigerant, R407C, requires strict cautions for keeping the
system clean, dry and tight.
A.Clean and dry
Foreign materials (including mineral oils such as SUNISO oil or
moisture) should be prevented from getting mixed into the system.
B.Tight
R407C does not contain any chlorine, does not destroy the
ozone layer, and does not reduce the earth's protection against
harmful ultraviolet radiation.
R407C 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 the chapter "Refrigerant piping work" carefully and follow
these procedures correctly.

Caution
Since R407C is a mixed refrigerant, the required additional
refrigerant must be charged in its liquid state. (If the refrigerant
is charged in a state of gas, its composition changes and the
system will not work properly.)
The connected indoor units must be of the FXY--P--series,
indoor units designed exclusively for R407C. If indoor units for
R22 are connected, normal operation cannot be assured.
1. INTRODUCTION
This installation manual concerns VRV plus series, RSEYP . These
units are designed for outdoor installation and used for cooling and
heatpump applications. The units are available in 7 standard sizes
with nominal cooling capacities ranging from 43.8 to 82.1kW and
nominal heating capacities ranging from 43.8 to 82.1kW.
The RSEYP units can be combined with Daikin VRV series BS and
indoor units for air conditioning purposes.
The present installation manual describes the procedures for
unpacking, installing and connecting the RSEYP 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.

Up to 32 indoor units can be connected to 1 outdoor unit
RSEYP24,26,28 and 30.
•
Make sure to connect indoor and BS units designed exclusively for
R407C.(FXY--P--series, BSVP--series)
•
Refer to the catalogue and/or engineering data book for model
numbers of indoor units which can be connected.
