The following is intended for the person responsible for installing or servicing the Solenoid Valve
Controller. Before conducting installation or electrical work, be sure to carefully read these
“Safety Precautions”. Follow instructions exactly in all installation or electrical work.
The precautions given in this manual consist of specific “Warnings” and “Cautions”. They provide
important safety related information and are important for your safety, the safety of others, and
troublefree operation of the system. Be sure to strictly observe all safety procedures. The labels and
their meanings are as described below.
This symbol refers to a hazard or unsafe procedure or practice which can result in
severe personal injury or death.
Warning
Caution
This symbol refers to a hazard or unsafe procedure or practice which can result in
personal injury or product or property damage.
Warning
Be sure to arrange installation at the dealer where the system was purchased or use a professional
installer.
Leaks, electric shock or fire may result if an inexperienced person performs any installation or wiring
Be sure to turn off the power source circuit breaker of the unit before installation or wiring.
High electrical voltages used in the unit may cause electric shock.
procedures incorrectly.
Only a qualified electrician should attempt to install this system, in accordance with the provisions of
the Technical standards for Electrical Installations, local regulations for indoor wirings and these
“Installation (Electric) and Service Instructions”. Be sure to use a dedicated electrical circuit.
Insufficient electrical circuit capacity may cause electric shock or fire.
Use the specified cables (type and wiring diameter) for the electrical connections, and securely connect
the cables. Run and fasten the cables securely so that external forces or pressure placed on the cables
will not be transmitted to the connection terminals. Overheating or fire may result if connections or
attachments are not secure.
Install in a location that is fully strong enough to support the weight of the unit. If it is not strong enough,
the unit may fall, resulting in injury.
Ventilate the work area if cooling gas leaks during installation. Poisonous gas can result if cooling gas
comes into contact with fire.
After installation, check to be sure that there are no gas leaks.
Poisonous gas can result if cooling gas leaks into the room and comes into contact with a fan heater,
stove, range, or other source of fire.
Caution
Do not install in a location subject to leakage of flammable gasses.
Fire can result if gas builds up around the unit.
2. Supplied Parts
1. Install the solenoid valve control PCB in the optional board box with the following procedure.
2. Wire according to the following procedure.
3. When you have finished wiring work, secure the cover of the optional board box with the supplied screw (4x4)
Install the board spacers in the holes in the base of the optional board box.
Note: When you do so, be careful of the direction of the solenoid valve conrol PCB(see following figure).
Attach the optional board box to the unit with the supplied screws(4x10).
Models without space inside electrical box
Connect the 3P yellow connector of power cable (Supplied part
②
) to OP1 (CN309) on the indoor control PCB.
Connect the 5P black connector of signal output cable (Supplied part
③
) to 3WAY (CN81) on the indoor control PCB.
Connect the ground wire of the power cables (3 core) to the indoor unit using the screw and washer (supplied part
⑦
).
* For the connecting location, refer to the indoor unit installation instructions.
*
When you use the power cables (2 core) for installing inside electrical box, ground connection is unnecessary.
Connect the ground wires of the power cables and solenoid valve kit or gas pipe valve kit to the optional board box.
*
When you use the power cables (2 core), only connect the ground wire of the solenoid valve kit or gas pipe valve kit
.
Connect the 3P white connector of power cable(Supplied part
②
) to POWER(CN002) on the
solenoid valve control PCB.
Connect the 6P white connector of signal output cable(Supplied part
③
) to OPTION/3WAY(CN001) on the
solenoid valve control PCB.
Connect the connector from the solenoid valve kit or gas pipe valve kit (9P red) to the 9P red connector (CN003) on the
solenoid valve control PCB.
Fasten the wires to the optional board box with the cable ties (supplied part
⑥
)
Note: When you do so, check to be sure that there are no nipped portions in the wiring.
Use the long cables and 3 core cables
when the solenoid valve controller is
installed outside the indoor unit.
