1. Safety precautions
Before installing the interface unit, make sure you read all the “Safety
precautions”.
Please report to your supply authority or obtain their consent before
connecting this equipment to the power supply system.
Warning:
Precautions that must be observed to prevent injuries or death.
Caution:
Precautions that must be observed to prevent damages to the unit.
Warning:
• The unit must not be installed by the user. Ask an installer or an authorised
technician to install the unit. If the unit is installed improperly, electric
shock, or re may be caused.
• For installation work, follow the instructions in the Installation Manual and
use tools and pipe components specically made for use with refrigerant
specied in the outdoor unit installation manual.
• The unit must be installed according to the instructions in order to minimize the risk of damages by earthquakes, typhoons, or strong winds.
Improperly installed unit may fall down and cause damage or injury.
The unit must be securely installed on a structure that can sustain its weight.
•
If the unit is mounted on an unstable structure, it may fall down and cause
damage or injury.
• All electric work must be performed by a qualied technician according to
local regulations and the instructions given in this manual. The unit must
be powered by dedicated power lines and the correct voltage and circuit
breakers must be used. Power lines with insufcient capacity or incorrect
electrical work may result in electric shock or re.
6. Service and Maintenance ........................................................................20
7. Requirement on local design ...................................................................21
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.
• 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 sufcient 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 specied 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.

2.2. Choosing the interface unit installation location
• Do not install the interface unit in outdoor location as it is designed for indoor
installation only. (The interface board and casing are not waterproof.)
• Avoid locations where the unit is exposed to direct sunlight or other sources of
heat.
• Select a location where easy wiring access to the power source is available.
• Avoid locations where combustible gases may leak, be produced, ow, or accu-
mulate.
• Select a level location that can bear the weight and vibration of the unit.
• Avoid locations where the unit is exposed to oil, steam, or sulfuric gas.
• Do not install in location that is hot or humid for long period of time.
2.3. Installing the interface unit (Fig. 2.3.1, 2.3.2, 2.3.3)
1. Remove 2 screws A from interface unit and remove the cover by sliding it upward
(See Fig. 2.3.1).
2. Install the 4 screws (locally supplied) in 4 holes (C hole).
* To prevent the unit from falling off the wall, select the appropriate screws (lo-
cally supplied) and secure the base horizontally to the appropriate wall location.

4.1.3. Connecting thermistor cable
Connect the thermistor 2 for the interface controller.
1. Target temp. thermistor (TH1)
Connect the thermistor for the target temp. to 1 and 2 on the terminal block (TB61)
on the interface controller.
2. HEX inlet temp. thermistor (TH11)
Connect the thermistor for the HEX inlet temp. to 3 and 4 on the terminal block
(TB61) on the interface controller.
3. Ref. liquid temp. thermistor (TH2)
Connect the thermistor for the ref. liquid temp. to 5 and 6 on the terminal block
(TB61) on the interface controller.
4. 2-phase temp. thermistor (TH5)
Connect the thermistor for the 2-phase temp. to 7 and 8 on the terminal block
(TB61) on the interface controller.
When the thermistor cables are too long, cut it to the appropriate length.
Do not bind it in the interface unit.
The 4 thermistors have the same specication except the color of cables, thus we do not specify which thermistor should be
installed to which position.
Notes: When multiple outdoor units are connected, conect thermistors to each interface unit respectively.
Caution:
Do not route the thermistor cables together with power cables.
The sensor part of the thermistor should be installed where user can not access. (It should be separated by the supplementary insulation from areas the user can access.)
4.1.4. Connecting external input
Demand control is available by external input.
Select input type by setting the switch of the interface controller, and it is possible to set capacity request when manual step mode (“Analog input” , “Remote switch” or “Modbus”) is selected.
