Before installing the zone controller, make sure you read all the “Safety
precautions”.
Warning:
Precautions that must be observed to prevent injuries or death.
Caution:
Precautions that must be observed to prevent damages to the unit.
After installation, perform the test run to ensure normal operation. Then explain
your customer the “Safety Precautions,” use, and maintenance of the unit based on
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.
Warning:
• The zone controller must not be installed by the user. Ask an installer or an
authorized technician to install the zone controller. If the zone controller is
installed improperly, electric shock, or fire may be caused.
• For installation work, follow the instructions in the Installation Manual and
use tools and pipe components specifically made for use with refrigerant
specified in the outdoor unit installation manual.
• The zone controller must be installed according to the instructions in or
-
der to minimize the risk of damages by earthquakes, typhoons, or strong
winds. Improperly installed zone controller may fall down and cause dam
-
ages or injuries.
•
The zone controller must be securely installed on a structure that can sus-
tain its weight.
If the zone controller is mounted on an unstable structure, it
may fall down and cause damages or injuries.
• All electric work must be performed by a qualified technician according
to local regulations and the instructions given in this manual. If the zone
controller is powered by dedicated power lines, correct voltage and circuit
breakers must be used. Power lines with insufficient capacity or incorrect
electrical work may result in electric shock or fire.
• 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 fire.
• Terminal block cover panel of the zone controller must be firmly fixed. If
the cover panel is mounted improperly, dust and moisture may enter the
zone controller, and it may cause electric shock or fire.
• Make sure to use accessories authorized by Mitsubishi Electric and ask
an installer or an authorized technician to install them. If accessories are
improperly installed, it may cause electric shock, or fire.
•
Do not remodel the zone controller. Consult an installer for repairs. If altera-
tions or repairs are not performed correctly, it may cause electric shock or fire.
• The user should never attempt to repair the zone controller or transfer it to
another location. If the zone controller is installed improperly, it may cause
electric shock or fire. If the
zone controller needs to be repaired or moved,
ask an installer or an authorized technician.
• When installing sensors and parts, do not expose the terminals.
1.1. Before installation (Environment)
Caution:
• Do not install the
zone controller 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 zone controller in an unusual environment. If the zone control-
ler
is installed or exposed to steam, volatile oil (including machine oil), sulfu
-
ric gas, briny air, the internal parts can be damaged.
• Do not install the zone controller where combustible gases may leak, be
produced, flow, or accumulate. If combustible gas accumulates around the
zone controller, it may cause fire or explosion.
• When installing the zone controller in a hospital or in a building where
communications 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 zone controller
to malfunction or to breakdown.
At the same time,
the noise and electric interference from the zone controller may disturb the
proper operation of medical equipment, and communications equipment.
1.2. Before installation or relocation
Caution:
• Be fully careful when moving the zone controller. Do not hold the packag
-
ing bands. Wear protective gloves to unpack and to move it, in order to
avoid your hands be 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
to get an electric shock.
• For the power lines, use standard cables of sufficient capacity. Otherwise,
it may cause a short circuit, overheating, or fire.
• When installing the power lines, do not apply tension to the cables. The
cables may be cut or overheated resulting in a fire.
• Make sure to ground the zone controller. Do not connect the ground wire
to gas or water pipes, lightning rods, or telephone grounding lines. If the
zone controller is not properly grounded, there may be a risk to get an
electric shock.
• Make sure to use circuit breakers (ground fault interrupter, isolating switch (+B
fuse), and molded case circuit breaker) with the specified capacity. If the circuit
breaker capacity is larger than the specified capacity, breakdown or fire may result.
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.
• 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 to get an
electric shock.
• After stopping operation, make sure to wait at least 5 minutes before turn
-
ing off the main power. Otherwise, it may cause breakdown.
• Be sure to safely dispose of the packaging materials.
Packaging materials,
such as nails and other metal or wooden parts may cause injuries.
• Do not wash the
zone controller. You may receive an electric shock.

1. Safety precautions
Mitsubishi Electric is not responsible for the failure of locally supplied parts.
1.5. Damper motors
Warning:
• The
zone controller
has signal outputs for damper motors however it can
not isolate power to them in the event of overheating. All damper motors
connected to the
zone controller must comply with National regulation.
• Zone controller must be powered off when changing or connecting
damper motor.
