Installation, electrical work and test run
WARNING
Before starting brazing work, evacuate combustible matters from around the site. It could cause fire. Provide a fire extinguisher at the work
place.
Implement the airtight test. If refrigerant leaks, it could cause oxygen shortage.
Open, and close, all valves according to instructions given on nameplates, or this manual.
If the valves are opened or closed incorrectly, there is a risk of injury due to refrigerant spouting or the internal pressure of the equipment
increasing, causing the refrigerant system to burst.
When handling refrigerant, put on leather gloves. Direct contact with hand could cause frostbite, or injury.
Always use nitrogen gas for airtight test.
If oxygen gas, acetylene gas, fluorocarbon gas, is used by mistake, it could cause explosion, or poisoning.
This condensing unit is specially designed for use of R744. It is strictly prohibited to mix any material other than R744 during installation, repair,
or relocation. If other refrigerant, or other combustible materials like air, oxygen, propane, or alcohol, are mixed, it could cause explosion, fire,
or injury.
CAUTION
Avoid installing at a place where combustible gas may leak. If the gas leaks, and accumulates around the condensing unit, it could catch fire.
Ventilate effectively. If refrigerant leaks accidentally, it could cause oxygen shortage.
Be sure to provide suitable sewer. If frost adhered to the surface of equipment melts, and flows out, it could wet around the equipment.
Place a sign board prohibiting people other than operating personnel from touching the condensing unit, or enclose it with protective fence.
If it is mishandled, it could cause injury.
Produce the refrigerant cycle within the range of specifications. If it is produced beyond the range, it could cause rupture, smoke, fire, or
electric shock.
Turn off the source power supply before starting maintenance in the condensing unit.
Use a circuit breaker with the contact gap of category 3, or higher, at the source power supply.
Shield communication cables used for communication with and remote monitoring of the indoor unit.
