4.5 Combining units and options
4.5.1 About combining units and options
NOTICE
To be sure your system setup (outdoor unit+indoor unit(s))
will work, you have to consult the latest technical
engineering data for VRV IV heat pump.
The VRV IV heat pump system can be combined with several types
of indoor units and is intended for R410A use only.
For an overview which units are available you can consult the
product catalogue for VRV IV.
An overview is given indicating the allowed combinations of indoor
units and outdoor units. Not all combinations are allowed. They are
subject to rules (combination between outdoor-indoor, single outdoor
unit use, multiple outdoor unit use, combinations between indoor
units, etc.) mentioned in the technical engineering data.
4.5.2 Possible combinations of indoor units
In general following type of indoor units can be connected to a VRV
IV heat pump system. The list is non-exhaustive and is depending
on both outdoor unit model and indoor unit model combinations.
▪ VRV direct expansion (DX) indoor units (air to air applications).
▪ AHU (air to air applications): EKEXV-kit+EKEQ-box are required,
depending on application.
▪ Aircurtain (air to air applications): CYQ/CAV (Biddle) series,
depending on application.
4.5.3 Possible options for the outdoor unit
INFORMATION
Refer to the technical engineering data for the latest option

Refrigerant branching kit
Description Model name
Refnet header KHRQ22M29H
KHRQ22M64H
KHRQ22M75H
Refnet joint KHRQ22M20T
KHRQ22M29T9
KHRQ22M64T
KHRQ22M75T
For the selection of the optimal branching kit, please refer to
"5.3.3To select refrigerant branch kits"on page13.
Cool/heat selector
In order to control the cooling or heating operation from a central
location, the following option can be connected:
Description Model name
Cool/heat change over switch KRC19-26A
Cool/heat change over PCB BRP2A81
With optional fixing box for the
switch
KJB111A
External control adaptor (DTA104A61/62)
To instruct specific operation with an external input coming from a
central control the external control adaptor can be used. Instructions
(group or individual) can be instructed for low noise operation and
power consumption limitation operation.
PC configurator cable (EKPCCAB)
You can make several commissioning field settings through a
personal computer interface. For this option EKPCCAB is required
which is a dedicated cable to communicate with the outdoor unit.
The user interface software is available on http://

5 Preparation
5.1 Overview: Preparation
This chapter describes what you have to do and know before going
on-site.
It contains information about:
▪ Preparing the installation site
▪ Preparing the refrigerant piping
▪ Preparing the electrical wiring
5.2 Preparing installation site
5.2.1 Installation site requirements of the
outdoor unit
▪ Provide sufficient space around the unit for servicing and air
circulation.
▪ Make sure the installation site withstands the unit's weight and
vibration.
▪ Make sure the area is well ventilated.
▪ Make sure the unit is level.
▪ Select a place where rain can be avoided as much as possible.
▪ Select the location of the unit in such a way that the sound
generated by the unit does not disturb anyone, and the location is
selected according the applicable legislation.
Do NOT install the unit in the following places:
▪ In potentially explosive atmospheres.
▪ In places where there is machinery that emits electromagnetic
waves. Electromagnetic waves may disturb the control system,
and cause malfunction of the equipment.
▪ In places where there is a risk of fire due to the leakage of
flammable gases (example: thinner or gasoline), carbon fibre,
ignitable dust.
▪ In places where corrosive gas (example: sulphurous acid gas) is
produced. Corrosion of copper pipes or soldered parts may cause
the refrigerant to leak.
