• After stopping operation, be sure to wait at least five minutes before turning off the main power switch.Otherwise, water leakage or breakdown may result.

1.5. Using R32 refrigerant outdoor units
CAUTION:

• Do not use refrigerant other than R32 refrigerant. If another refrigerant is used, the chlorine will cause the oil to deteriorate.
• Use the following tools specifically designed for use with R32 refrigerant. The following tools are necessary to use R32 refrigerant. Contact your nearest dealer for any questions.

Tools (for R32)

Gauge manifold| Flare tool
Charge hose| Size adjustment gauge
Gas leak detector| Vacuum pump adapter
Torque wrench| Electronic refrigerant charging scale

• Be sure to use the correct tools. If dust, debris, or moisture enters the refrigerant lines, refrigeration oil deterioration may result.

Installation location

2.1. Choosing the outdoor unit installation location

• R32 is heavier than air—as well as other refrigerants—so tends to accumulate at the base (in the vicinity of the floor). If R32 accumulates around base, it may reach a flammable concentration in case room is small. To avoid ignition, maintaining a safe work environment is required by ensuring appropriate ventilation. If a refrigerant leak is confirmed in a room or an area where there is insufficient ventilation, refrain from using of flames until the work environment can be improved by ensuring appropriate ventilation.
  • Avoid locations exposed to direct sunlight or other sources of heat.
  • Select a location from which noise emitted by the unit will not inconvenience neighbors.
  • Select a location permitting easy wiring and pipe access to the power source and indoor unit.
  • Avoid locations where combustible gases may leak, be produced, flow, or accumulate.
  • Note that water may drain from the unit during operation.
  • Select a level location that can bear the weight and vibration of the unit.
  • Avoid locations where the unit can be covered by snow. In areas where heavy snow fall is anticipated, special precautions such as raising the installation location or installing a hood on the air intake must be taken to prevent the snow from blocking the air
  intake or blowing directly against it. This can reduce the airflow and a malfunction may result.
  • Avoid locations exposed to oil, steam, or sulfuric gas.
  • Use the transportation handles of the outdoor unit to transport the unit. If the unit is carried from the bottom, hands or fingers may be pinched.

• Install outdoor units in a place where at least one of the four sides is open, and in a sufficiently large space without depressions. (Fig. 2-1)

CAUTION:

• Perform grounding.
  Do not connect the ground wire to a gas pipe, water pipe arrester or telephone ground wire. Defective grounding could cause an electric shock.

• Do not install the unit in a place where an inflammable gas leaks. If gas leaks and accumulates in the area surrounding the unit, it could cause an explosion.

• Install a ground leakage breaker depending on the installation place (where it is humid). If a ground leakage breaker is not installed, it could cause an electric shock.

• Perform the drainage/piping work securely according to the installation manual.
  If there is a defect in the drainage/piping work, water could drop from the unit and household goods could be wet and damaged.

• Fasten a flare nut with a torque wrench as specified in this manual.
  When fastened too tight, a flare nut may be broken after a long period and cause a leakage of refrigerant.
