Safety Considerations EDUS121131
222 Installation Manual
• Take adequate measures to prevent the condenser unit from being used as a shelter by small animals. Small animals
making contact with electrical parts can cause malfunctions, smoke, or fire. Instruct the customer to keep the area
around the unit clean.
• Install the power supply and control wires for the indoor and outdoor units at least 3.5 feet away from televisions or
radios to prevent image interference or noise. Depending on the radio waves, a distance of 3.5 feet may not be sufficient
to eliminate the noise.
• Dismantling the unit, treatment of the refrigerant, oil and additional parts must be done in accordance with the
relevant local, state, and national regulations.
• Do not use the following tools that are used with conventional refrigerants: gauge manifold, charge hose, gas leak detector,
reverse flow check valve, refrigerant charge base, vacuum gauge, or refrigerant recovery equipment.
• If the conventional refrigerant and refrigerator oil are mixed in R-410A, the refrigerant may deteriorate.
• This air conditioner or heat pump is an appliance that should not be accessible to the general public.
• As design pressure is 478 psi, the wall thickness of field-installed pipes should be selected in accordance with the relevant
local, state, and national regulations.
