Solenoid Valve
1. Safety Precautions
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.
Warning This symbol refers to a hazard or unsafe procedure or practice which can result in
severe personal injury or death.
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
procedures incorrectly.
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.
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.
