Refrigerant Pipework must be installed within limitations detailed
in the table below. Each system is supplied with the appropriate
branch pipe. Pipe connections to the branch kits must be brazed
and it is essential to use nitrogen purge while making the
connections.

Capacities
Mitsubishi Heavy Industries has made a giant leap forward in air conditioning
and heat pump technology, with the development of high performance FD
Multi Systems. These systems allow twin/triple/quad indoor units to be
installed and connected to one outdoor unit. This provides a saving compared to the
installation cost of several standard split systems.
The new FDA Multi Systems are ideal for open plan areas. It is not advisable to install
the connected indoor units in different rooms. Systems are supplied with the relevant
branch pipe kits, and one controller per system.
7-Day Programmable Timer - now included in standard controls specification.
The CoP (Coefficient of Performance) has been dramatically increased, up to
3.67 on some models. This means the system can deliver 3.67kW of heating, whilst
consuming only 1.0kW of electrical power. This has been achieved by combining
advanced Mitsubishi technology with R410A.
air conditioning

FDA Multi Systems
Ideal for open plan areas from 20m 2 to 6000m 2
Cost effective solution for cooling and
heating applications:
• Much lower cost than individual split
systems
• Reduced number of outdoor units
• Less power supplies required
• Less refrigerant pipework entering the
building
• Cost savings of installation
• Simple wiring and control
arrangements
• High performance R410A
systems
MIX-MATCH It is possible to have cassette
units matched with wall, ceiling or ducted
indoor units, as required.
Indoor unit capacity indexes must be as
those listed on opposite page.
SIMPLE CONTROL All units on one system
are connected to one controller, and will
all operate in the same mode, i.e. cooling
/ fan only / heating.
It is not advisable to have indoor units
installed in separate rooms.
FDA Twin, Triple & Quad
System 7.2kW to 16kW
FDA Twin, Triple & Quad

All new EHPAC range of indoor units have
wired controllers, and compatible for FDA
Multi application.
Typical applications of FDA Multi Systems
are:
• Retail Stores
• Convenience Stores
• Petrol Station Shops
• Open Plan Offices
• Large Restaurants

Multi Systems have all indoor units operating
in the same mode (cool or heat) at the same
time. They are ideal for open plan areas, such
as large offices, retail shops and stores, fitness
gyms, conference halls. They are not suitable
for indoor units to be installed in separate rooms.
Use the new KX INVERTER Multi Systems for
these applications.
