the information in the Operation Manual provided by local application manufacturer.
Both the Installation Manual and the Operation Manual must be given to the user.
These manuals must always be kept by the actual users.

: Indicates a part which must be grounded.

Warning:

Carefully read the labels attached to the unit.

• Only the specified cables can be used for wiring. Connections must be
made securely without tension on the terminals. If cables are connected or
installed improperly, It may result in overheating or re.

• Terminal block cover panel of the unit must be rmly xed. If the cover
panel is mounted improperly, dust and moisture may enter the unit, and it
may cause electric shock or re.

• Make sure to use accessories authorised by Mitsubishi Electric and ask
an installer or an authorised technician to install them. If accessories are
improperly installed, it may cause electric shock, or re.

• Do not remodel the unit. Consult an installer for repairs. If alterations or
repairs are not performed correctly, it may cause electric shock or re.

• The user should never attempt to repair the unit or transfer it to another
location. If the unit is installed improperly, it may cause electric shock or
re. If the interface unit needs to be repaired or moved, ask an installer or
an authorised technician.

• When installing sensors and parts, do not expose the terminals.

1.1. Before installation (Environment)

Caution:

• Do not install the interface unit in outdoor location as it is designed for
indoor installation only. Otherwise electric shock or breakdown may be
caused by water drop, wind or dust.
Do not use the unit in an unusual environment. If the interface unit is installed

•
or exposed to steam, volatile oil (including machine oil), or sulfuric gas, or
exposed to briny air, the internal parts can be damaged.

• Do not install the unit where combustible gases may leak, be produced,
ow, or accumulate. If combustible gas accumulates around the unit, it may
cause re or explosion.

1.2. Before installation or relocation

Caution:

• Be very careful when moving the units. Do not hold the packaging bands.
Wear protective gloves to unpack and to move it, in order to avoid your
hands being injured by parts.

1.3. Before electric work

Caution:

• Be sure to install a circuit breaker. If it is not installed, there may be a risk

of electric shock.

• For the power lines, use standard cables of sufcient capacity. Otherwise,

it may cause a short circuit, overheating, or re.

• When installing the power lines, do not apply tension to the cables. The

cables may be cut or overheated resulting in a re.

1.4. Before starting the test run

Caution:

• Turn on the main power switch of the outdoor unit more than 12 hours

before starting operation. Starting operation immediately after turning on
the power switch can severely damage the internal parts. Keep the main
power switch turned on during the operation period.

• When installing the unit in a hospital or in a building where communica-

tions equipment are installed, you may need to take measure to noise and
electronic interference. Inverters, home appliances, high-frequency medical
equipment, and radio communications equipment can cause the interface
unit to malfunction or to breakdown. At the same time, the noise and elec­tric interference from the interface unit may disturb the proper operation of
medical equipment, and communications equipment.

• Be sure to safely dispose of the packaging materials. Packaging materials,
such as nails and other metal or wooden parts may cause injury.

• Do not wash the interface unit. You may receive an electric shock.

• Make sure to ground the unit. Do not connect the ground wire to gas or

water pipes, lightning rods, or telephone grounding lines. If the unit is not
properly grounded, there may be a risk of electric shock.

• Make sure to use circuit breakers (ground fault interrupter, isolating switch

(+B fuse), and molded case circuit breaker) with the specied capacity. If
the circuit breaker capacity is larger than the specified capacity, break­down or re may result.

• Before starting operation, check that all protective parts are correctly in-

stalled. Make sure not to get injured by touching high voltage parts.

• Do not touch any switch with wet hands. There may be a risk of electric

shock.

• After stopping operation, wait at least 5 minutes before turning off the

main power. Otherwise, it may cause breakdown.

<Handling precautions>

(1) Use an SD memory card that complies with the SD standards. Check that the SD

memory card has a logo on it of those shown to the right.

(2) SD memory cards to the SD standards include SD, SDHC, miniSD, micro SD,

and microSDHC memory cards. The capacities are available up to 32 GB.

Choose that with a maximum allowable temperature of 55ºC.

(3) When the SD memory card is a miniSD, miniSDHC, microSD, or micro SDHC

memory card, use an SD memory card converter adapter.

(4) Before writing to the SD memory card, release the write-protect switch.

(a) For insertion, push on the SD memory card until it clicks into place.
(b) For ejection, push on the SD memory card until it clicks.

Note: To avoid cutting ngers, do not touch sharp edges of the SD

memory card connector (CN108) on the interface controller.

(5) Before inserting or ejecting an SD memory card, make sure to power off the

system. If an SD memory card is inserted or ejected with the system powered on,
the stored data could be corrupted or the SD memory card be damaged.
*An SD memory card is live for a short duration after the system is powered off.
Before insertion or ejection wait until the LED lamps on the interface control

board are all off.

(6) The read and write operations have been veried using the following SD memory

cards, however, these operations are not always guaranteed as the specica­tions of these SD memory cards could change.

Manufacturer Model Tested in

(2) Diameter of header

With a bigger size header , the refrigerant ow velocity decreases and this disturbs the sufcient circulation of refrigerant oil. As a result, the refrigerant oil does not
ow properly and could cause a serious damege of compressor.

Use the pipe whose outside diameter is less than the value shown in the table below.
