Introduction
Precautions
Please read these instructions carefully before starting the installation.
This equipment should only be installed by suitably trained operatives.
In all cases ensure safe working practice: Observe precautions for persons in the vicinity of the works.
Ensure that all local, national and international regulations are satisfied.
Check that the electrical specifications of the unit meet the requirements of the site.
Carefully unpack the equipment, check for damage or shortages. Please report any damage immediately.
These units comply with EU Directives:
73/23/EEC (Low Voltage Directive), 89/336/EEC (Electromagnetic Compatibility) and 97/23/EC (Pressure Equipment
Directive). Accordingly, they are designated for use in commercial and industrial environments*.
Avoid installation in the following locations:
Where there is danger of flammable gas leakages.
Where there are high concentrations of oil.
Where the atmosphere contains an excess of salt (as in coastal areas). The air conditioner is prone to failure when
used under this condition unless special maintenance is provided.
1
Where the airflow from the outdoor unit may cause annoyance.
Where the operating noise of the outdoor unit may cause annoyance.
Where the foundation is not strong enough to fully withstand the weight of the outdoor unit.
Where the water drainage may cause a nuisance or a hazard when frozen.
Where strong winds may blow against the air outlet of the outdoor unit.
Precautions for R407C outdoor units
R407C outdoor units use synthetic oils which are extremely hygroscopic. Therefore ensure that the refrigerant system
is NEVER exposed to air or any form of moisture.
Mineral oils are unsuitable for use in these units and may lead to premature system failure.
Use only equipment which is suitable for use with R407C. Never use equipment which has been used with R22.
R407C should only be charged from the service cylinder in the liquid phase. It is advisable to use a gauge manifold set
equipped with a liquid sight glass fitted in the centre (entry) port.
* 97/23/EC Pressure Equipment Directive information
Conformity assessment procedure: Module D1
Pressure equipment:
Compressor, category II, Module A1
Accumulator, category I

Outline of MMS (Modular Multi System)
• Branching
Combination of line and header branching is highly flexible. This allows for the
shortest design route possible, thereby saving on installation time and cost.
Line/header branching after header branching is only available with Toshiba’s
Multi Modular System.

• Compact design
The design of the Toshiba MMS outdoor unit allows for
easy unit maneuvering into any standard lift. Its size also
allows it to be easily installed in limited spaces.
• Largest system capacity
Toshiba’s Multi Modular System can be combined up to
128.8 kW (46 HP).

• Advanced bus communication system
Wiring between indoor and outdoor unit is a simple 2wire system.
Communication address is also automatically configured.
A default test mode operation is available.
• Self diagnostic system
Comprehensive troubleshooting code enables quick
identification of problems arising.
• High lift design
Real pipe length of 100m (equivalent length 125m) and
vertical lift of 50m is made possible with Toshiba’s Multi
Modular System.
Vertical lift between indoor units of 30m is the highest in
the market.
This allows for greater flexibility in the location of the
system.
• Multiple indoor units
Indoor units with different capacities and configurations
can be combined up to 135% of the outdoor unit capacity.
A maximum of 40 indoor units can be combined with the
46 HP outdoor module.
• Intelligent control
Toshiba’s MMS intelligent controls and modulating
valves deliver the required capacity, according to the
load variation from 50% to 100%.
The intelligent controls and modulating valves limit or
increase the cooling/heating capacity dynamically so
humidity and temperature are kept in the comfort zone.
From 1st branching to the
farthest indoor unit: 50 m
