Before Installation (Relocation) - Electrical Work; Before Starting The Test Run - Mitsubishi Electric City Multi PAC-PH01EHYU-E Manuel D'installation

1.3. Before installation (relocation) -
electrical work
Caution:
• Ground the unit.
- Do not connect the ground wire to gas or water pipes, lightning rods, or
telephone ground lines. Improper grounding may result in electric shock.
• Install the power cable so that tension is not applied to the cable.
- Tension may cause the cable to break and generate heat and cause a fire.
• Install a leak circuit breaker, as required.
- If a leak circuit breaker is not installed, electric shock may result.
• Use power line cables of sufficient current carrying capacity and rating.
- Cables that are too small may leak, generate heat, and cause a fire.
• Use only a circuit breaker and fuse of the specified capacity.
- A fuse or circuit breaker of a larger capacity, or the use of a substitute
simple steel or copper wire may result in a general unit failure or fire.
• Be careful that the installation base is not damaged by long use.
- If the damage is left uncorrected, the unit may fall and cause personal injury
or property damage.
• Do not touch the electrical parts with bare hands while the unit is in
operation or immediately after operation.
- Doing so may result in burns.
• If a large electric current flows due to malfunction or faulty wiring,
earth-leakage breakers on the unit side and on the upstream side of the
power supply system may both operate.
Depending on the importance of the system, separate the power supply
system or take protective coordination of breakers.
• Stop the operation and turn off the power before cleaning.
• Do not wash the air conditioner units.
- Washing them may cause an electric shock.
• Be very careful about transporting the product.
- One person should not carry the product. Its weight is in excess of 20 kg
[45 LBS].
- Some products use PP bands for packaging. Do not use any PP bands as a
means of transportation. It is dangerous.
• Safely dispose of the packing materials.
- Packing materials, such as nails and other metal or wooden parts, may
cause stabs or other injuries.
- Tear apart and throw away plastic packaging bags so that children will not
play with them. If children play with a plastic bag which has not been torn
apart, they face the risk of suffocation.
• Never connect in reverse phases.
• Install the power cable so that tension is not applied to the cable.
• Do not wash the air conditioner units.

1.4. Before starting the test run

Caution:
• Turn on the power at least 12 hours before starting operation.
- Starting operation immediately after turning on the main power switch can
result in irreversible damage to internal parts. Keep the power switch turned
on during the operational season. Make sure of the phase order of power
supply and voltage between each phase.
• Do not touch the switches with wet fingers.
- Touching a switch with wet fingers can result in an electric shock.
• Do not touch the refrigerant pipes during and immediately after
operation.
- During and immediately after operation, the refrigerant pipes may be hot or
cold, depending on the condition of the refrigerant flowing through the
refrigerant piping, compressor, and other refrigerant cycle parts. Your hands
may suffer burns or frostbite if you touch the refrigerant pipes.
• Do not operate the air conditioner with the panels and guards removed.
- Rotating, hot, or high-voltage parts can cause injuries.
• Do not turn off the power immediately after stopping operation.
- Always wait at least 5 minutes before turning off the power. Otherwise,
drainage water leakage or mechanical failure of sensitive parts may occur.
