READ THESE INSTRUCTIONS CAREFULLY BEFORE
INSTALLATION AND OPERATION.

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.

IF UNSURE OF INSTALLATION PROCEDURES OR USE,
ALWAYS CONTACT YOUR DAIKIN DEALER FOR
ADVICE AND INFORMATION.

The English text is the original instruction. Other languages are
translations of the original instructions.

INTRODUCTION

 Do only use this system in combination with a field-

supplied air handling unit. Do not connect this system
to other indoor units.

 Only optional controls as listed in the optional

accessories list can be used.

Field-supplied air handling units can be connected with a Daikin
condensing unit via a control box and expansion valve kit. Each air
handling unit can be connected with 1 control box and 1 expansion
valve kit. This manual describes the installation of the expansion
valve kit and the installation and operation of 2 types of control
boxes.

We distinguish 2 different control boxes, each with its own application
and installation requirements.

 EKEQFCBA control box (3 possible operation modes)

 Operation with 0–10 V input to control the capacity

An external controller is needed to control the capacity. For
details of the necessary functions of the external controller
refer to paragraph "Operation with 0–10 V capacity control: X

control" on page 12. There are 2 different 0–10 V operation

modes that can be used to control the room temperature or
air discharge temperature.

 Operation with fixed T

- In cooling this system operates on a fixed evaporating
temperature.

- In heating this system operates on a fixed condensing
temperature.

 EKEQDCB control box

The system will operate as a standard indoor unit to control the
room temperature. This system does not require a specific
external controller.

 Connectivity to DIII-net devices only allowed with:

- ITouch Manager II

- Modbus Interface DIII

 This equipment is not designed for year-round cooling

applications with low indoor humidity conditions, such as
Electronic Data Processing rooms.

 This appliance can be used by children aged from 8 years and

above and persons with reduced physical, sensory or mental
capabilities or lack of experience and knowledge if they have
been given supervision or instruction concerning use of the
appliance in a safe way and understand the hazards involved.
Children shall not play with the appliance. Cleaning and user
maintenance shall not be made by children without supervision.

INSTALLATION

 For installation of the air handling unit, refer to the air handling

unit installation manual.

 Never operate the air conditioner with the discharge pipe

thermistor (R3T), suction pipe thermistor (R2T) and pressure
sensors (S1NPH, S1NPL) removed. Such operation may burn
out the compressor.

 The equipment is not intended for use in a potentially explosive

atmosphere.

(*) For EKEQF, the remote controller is not used for operating the unit, but for

service and during installation. Therefore a cool/heat selector KRC19-26A6 is
required for the selection of heating, cooling or fan only operation. Refer to the
installation manual of the outdoor unit for details.

(*)

 Refer to the installation manual of the outdoor unit for details on

refrigerant piping, additional refrigerant charging, and inter-unit
wiring.

Since design pressure is 4 MPa or 40 bar, pipes of larger
wall thickness may be required. Refer to "Selection of

piping material" on page 5.

 Precautions for R410A

 The refrigerant requires strict cautions for keeping the

system clean, dry and tight.

- Clean and dry
Foreign materials (including mineral oils or moisture)
should be prevented from getting mixed into the system.

-Tight
Read "Piping installation" on page 4 carefully and follow
these procedures correctly.

 Since R410A is a mixed refrigerant, the required additional

refrigerant must be charged in its liquid state. (If the
refrigerant is in state of gas, its composition changes and the
system will not work properly).

 The connected air handling units must have heat exchangers

designed exclusively for R410A.

Cautions for selection of the air handling unit

Select the air handling unit (field supply) according to the technical
data and limitations mentioned in Table 1.

Lifetime of the outdoor unit, operation range or operation reliability
may be influenced if you neglect these limitations.

with field-supplied air handling units
4P383212-1B – 2016.10

NOTE

 If the total capacity of the connected indoor units

exceeds the capacity of the outdoor unit, cooling
and heating performance may drop when running
the indoor units.
Refer to the section on performance charac­teristics in the Engineering Data Book for details.

 The capacity class of the air handling unit is

determined by the selection of the expansion
valve kit according to Table 1.

ERQ outdoor unit

The EKEQ(D/FA) control boxes can only be connected to an ERQ
outdoor unit in pair application. Only 1 expansion valve kit
EKEXV63~250 can be used per control box and per air handling unit.

1 Selecting the condensing unit

Depending on necessary capacity of the combination an outdoor
unit needs to be selected (see "Engineering databook" for
capacity).

 Each outdoor unit can be connected to a range of air

handling units.

 The range is determined by the allowed expansion valve kits.

2 Selecting the expansion valve

The corresponding expansion valve needs to be selected for
your air handling unit. Select the expansion valve according to
the above limitations.

NOTE

 The expansion valve is an electronic type, it is

controlled by the thermistors that are added in
the circuit. Each expansion valve can control a
range of air handling units sizes.

 The selected air handling unit must be

designed for R410A.

 Extraneous substances (including mineral oils

or moisture) must be prevented from getting
mixed into the system.

 SST: saturated suction temperature at exit of

air handling unit.

3 Selecting the capacity setting adaptor (see accessories)

 The corresponding capacity setting adaptor needs to be

selected depending on the expansion valve.

VRV IV range outdoor units

The EKEQF control box can be connected to some types of VRV IV
outdoor unit (refer to the Engineering Data Book for outdoor units that
are in scope) with a maximum number of 3 connectable control boxes
to 1 system. 1 control box can be combined with 1 EKEXV kit. In this
configuration it is only allowed to connect air handling units. The
combination with VRV DX indoor units or other types of indoor units
is not allowed.

Depending on the air handling unit heat exchanger, a connectable
EKEXV (expansion valve kit) must be selected to following
limitations.

1 The air handling unit can be considered as a standard VRV

indoor unit. The combinations of EKEXV kits (maximum 3) are
restricted by the connection ratio limitations: 90~110%.

Additional limits exist when connecting the
EKEQFCBA control box. These can be found in the
Engineering Data Book of the EKEQFCBA and in this
manual.

2 Selecting the expansion valve

A corresponding expansion valve needs to be selected for your
air handling unit. Select the expansion valve according to the
above limitations.

NOTE

 The expansion valve (electronic type) is

controlled by the thermistors that are added in
the circuit. Each expansion valve can control a
range of air handling unit sizes.

 The selected air handling unit must be

designed for R410A.

 Extraneous substances (including mineral oils

or moisture) must be prevented from getting
mixed into the system.

 SST: saturated suction temperature at exit of

air handling unit.
