SANYO's Brand Vision
SANYO HVAC consistently builds new ideas to help build
your business. By delivering multi-zone options, space-saving
and environmentally friendly designs, our solutions are evolving,
improving solutions.
Flexible Combinations: ECOi allows multiple indoor unit
combinations that provide you with the utmost in flexible
solutions. The system also allows multiple unit connectivity
providing up to 130% of the total capacity of the condensing
unit. This provides for up to 17 indoor units connected to one
condensing unit.
Inverter Control Compressor: All ECOi systems utilize highly
advanced inverter controlled compressor technology. By varying
the rotational speed of the compressor, the inverter control can
precisely match the amount of refrigerant being delivered to
the needs of each zone. This intelligent approach helps realize
excellent efficiencies during partial-load conditions. This allows
all occupants to enjoy consistent room temperature, regardless
of any increases or decreases in the heat load during the day.
ECOi quite simply knows what you need, and when you need
it throughout the day. And even better, it does so with energy
efficiency in mind.
Lower running and life cycle costs: SANYO Ecoi VRF
systems are amongst the most efficient VRF systems on the
market, offering COPs in excess of 4.0 at full load conditions.
The system is also designed to make sure that we reduce the
running cost of each system by using our unique road map
control routine to ensure that the most efficient combination
of compressors are running at any one time. Improved defrost
sequencing also reduces running cost by defrosting each out
door coil in turn when conditions allow.

3-Way ECOiTM VRF Heat Recovery
Commercial of fice buildings are subject to fluctuating heat levels generated from electronic office equipment,
lighting and varying occupant levels. Also, hotels, nursing homes and other commercial living spaces often have
times when occupants will want either heating or cooling at the same time. The heat recovery system offers the
perfect solution for stabilizing the air temperature by providing all the features of a heat pump system - and the
added flexibility of simultaneous cooling and heating from one refrigerant pipe network.

Safety Precautions
Usage
○
The air conditioners listed herein are only for cooling/heating ar eas used by
people. Do not use the unit for foods, animals, plants, precision machines,
wor ks of art or other objects. Doing so may cause damage to the unit. Do not
use the unit for vehicles or vessels. Doing so may cause unit water leakage
and short circuiting.
○
Please read t he Operating Instruc tions carefully and use the air conditioner
properly.
Caution On Installation and Use
Location
Avoid Installation in Highly Humid Locations
Exposure to Oil
Cleaning
Features of Heat Pump Heating
Blocking air intake or outlet can be the cause of trouble including the
loss of air flow power, or short-cycled air emission drawn into the
intake. Be sure to install in an airy place.
(1) Avoid installation where the humidit y is excessive. This causes
condensation during cooling.
(2) Installation in a room where the temperature and humidity are
high around the ceiling due to sunlight will result in condensation.
Use insulation or take other preventive measures to block the
sunlight.
Avoid installation where there is exposure to oil or soot (such as in
kit chens or machiner y plants). Oil will adhere to the heat exchange.
This will lower heat exchange per formance, emit mist, or deform or
damage synthetic resin parts.
After using the air conditioner for sever al seaso ns, the insides
bec ome dirty and this results in low per formance. In addition to
regular cleaning, a maintenance contract with a service person is
recommended.
Heating power (kW) indicated in the catalog is based on the following
conditions: outdoor temperature of 47°F (DB ) and indoor temperature of
70°F (DB), as specified by ARI. Heating capacit y decreases as outdoor
temperature drops. Therefore, if heating power is insuf ficient due to low
outdoor temperature, use the air conditioner together with other heating
equipment. When heated air rises and collects in a room with a high
ceiling, install an air circulator as well.
○
Requires a qualified technician /installer to inst all the air conditioner.
Improper self-installation may result in water leakage, electric shock or fire.
○
When installing in a small room, take measures to keep ref rigerant leakage
within acceptable density limits, as outlined by local/national safety code
requirements.
○
Do not inst all wher e inflammable gas may leak or inflammable objec ts
exist. Do not install where t here is any in flammable gas emission, inflow or
leftover, or where carbon fibers are in the air. This could be the cause of fire.
The noise emission rate indica ted in the c at alog shows values (A
scale) measured in an anechoic chamber. In actual installation
conditions, noise emission is generally gre at er than the indicated
rate due to surrounding noise and echoing.
Odor Emissions
Even though an air conditioner does not cont ain odor-emitting par ts,
discharged air can, in certain conditions, have an unpleasant odor.
This is the result of odorous par ticles such as ones from smoke,
cosmetics, and foods, affixing themselves to the air conditioner.
Although the odor does not affect the performance, cleaning the air
filter and the inside of the air conditioner is recommended.
Noise Caused by Electromagnetic Waves
When installing near equipment that emits electromagnetic wav es,
be sure that the air conditioner does not suffer noise damage.
Remote Control Wiring
For remote contr ol wir ing and control wiring between indoor units,
do not install with the pow er wiring (20 8/2 30V) in the same tube nor
wherever power wiring exists. Doing so may cause a malfunction
ISO Certification
SANYO Electric Air Conditioning Co., Ltd. ( Tochigi Ja pan)

Do not install an air conditioner in a room where the limit density will be exceeded if refrigerant leaks. The refrigerant (R410A) used by this system is itself a safe refrigerant; however, if for some reason the refrigerant leaks and the limit density is exceeded, there is a risk of injury to persons due to a lack
of oxygen. For further information, ask your dealer or consult references such as an engineering manual to ensure you install the air conditioner correctly.
