1. General Information

MRVllI-S adopts refrigerant R410a, which is the new generation of H-MRV. It is with DC inverter technology, high

efciency and energy saving, intelligent control, etc. All indoor units are with EEV to adjust the refrigerant ow,

collect the data by the precise temp. sensor. lndoors adopt the indoors of MRVllI-C below 48000BTU/h, add the

central control, room card function on the basis of original H-MRV. The system can realize max. 1 to 9.

Features:

1. High efciency and energy saving

1.1 Precise control, optimum operation

a. Simulate pressure control, to realize every indoor unit energy-saving and optimum operation.

b. Adopt inverter technology, adjust outdoor total load according to the actual request.

1.2 Indoor individual control, economic running

1.3 Advanced technology, high efciency, and energy saving

1.4 High efcient rotary compressor

a. Precise control EEV

b. Excellent piping system design

c. Long distance of refrigerant piping

1.5 Inverter operation, temperature sensor technology, reduce power consumption

2. Beautiful and comfortable

a. Compact outdoor appearance design

b. Perfect cooling and heating, more comfortable

c. Super slim design, t for the decor

3. Healthy and environment friendly

a. Adopt environment friendly refrigerant R410a, protect ozone layer against the earth being warmed up

b. Intelligent healthy module for removing formaldehyde, easily resolve the decoration pollution

c. Strong ultraviolet radiation to kill the bacteria, make indoor air more healthy

4. More convenient

a. Flexible control indoors

One outdoor can control multiple indoors at the same time

b. Multiple indoor control types

Infrared control, wired control, infrared control + wired control, central control

c. Free combination

Due to the different space, select indoor type freely

d. Multiple air sending, air return types

5. Easy installation

Super long piping system, free installation

8.1 Installation cautions

SAFETY PRECAUTIONS

■ Please read these "Safety Precautions" rstly then accurately execute the installation work.

■ Though the precautionary points indicated herein are divided under two headings, "WARNING" and "CAUTION",

those points which are related to the strong possibility of an installation done in error resulting in death or

serious injury are listed in the "WARNING" section. However, there is also a possibility of serious consequences

in relationship to the points listed in the "CAUTION" section as well. In either case, important safety related

information is indicated, so by all means, properly observe all that is mentioned.

■ After completing the installation, along with conrming that no abnormalities were seen from the operation tests,

please explain operating methods as well as maintenance methods to the user (customer) of this equipment,

based on the owner's manual.

■ Moreover, ask the customer to keep this sheet together with the owner's manual.

WARNING

■ This system should be applied to places of ofce, restaurant, residence and the like. Application to inferior

environment such as engineering shop could cause equipment malfunction.

■ Please entrust installation to either the company which sold you the equipment or to a professional contractor.

Defects from improper installations can be the cause of water leakage, electric shocks and res.

■ Execute the installation accurately, based on following the installation manual. Again, improper installations can

result in water leakage, electric shocks and res.

■ When a large air-conditioning system is installed to a small room, it is necessary to have a prior planned

countermeasure for the rare case of a refrigerant leakage, to prevent the exceeding of threshold concentration. In

regards to preparing this countermeasure, consult with the company from which you purchased the equipment,

and make the installation accordingly. In the rare event that a refrigerant leakage and exceeding of threshold

concentration does occur, there is the danger of a resultant oxygen deciency accident.

■ For installation, conrm that the installation site can sufciently support heavy weight. When strength is

insufcient, injury can result from a falling of the unit.

■ Execute the prescribed installation construction to prepare for earthquakes and the strong winds of typhoons and

hurricanes, etc. Improper installations can result in accidents due to a violent falling over of the unit.

■ For electrical work, please see that a licensed electrician executes the work while following the safety standards

related to electrical equipment, and local regulations as well as the installation instructions, and that only

exclusive use circuits are used. Insufcient power source circuit capacity and defective installment execution can

be the cause of electric shocks and res.

■ Accurately connect wiring using the proper cable, and insure that the external force of the cable is not conducted

to the terminal connection part, through properly securing it. Improper connection or securing can result in heat

generation or re.

■ Take care that wiring does not rise upward, and accurately install the lid/service panel. Its improper installation

can also result in heat generation or re.

■ When setting up or moving the location of the air conditioner, do not mix air etc. or anything other than the

designated refrigerant (please see nameplate) within the refrigeration cycle.

■ Rupture and injury caused by abnormal high pressure can result from such mixing.

■ Always use accessory parts and authorized parts for installation construction. Using parts not authorized by this

company can result in water leakage, electric shock, re and refrigerant leakage.
