YMGI Group will not be responsible for any personal injury or any property damage caused by
improper or incorrect installation, improper service or maintenance or by not following the instructions
listed in this manual.
DO NOT pull on the power supply cords or refrigeration lines that are connected to the indoor and outdoor
units. Install the power supply cords and secure them into position. PVC line set cover is recommended for the
outdoor unit to protect against rain, sunlight and accidental damage.
DO NOT allow cold air to blow directly onto people for a prolonged period, as this could make people cold and
uncomfortable.
DO NOT undersize any of the power supply wires.
DO NOT connect several units to a single breaker. Don't undersize or oversize the circuit breaker. A poorly
sized circuit breaker can cause unit failure and even fire.
DO NOT wire or open a unit while the unit is running. Make sure to disconnect the power supply and switch off
all circuits prior to inspecting or servicing the unit. Inspecting and servicing the unit while the power supply is
connected, and the circuits are switched on could cause an electrical shock or fire.
DO NOT install the indoor unit near any cooking surfaces, in direct sunlight or any ventilation systems. Poor
placement could decrease efficiency and waste energy.
DO NOT install the unit in places where there is exposure to flammable materials or gas.
DO NOT apply chemical solvents, flammable insecticides, or abrasive materials directly on the unit. Clean the
unit only with a soft dry cloth.
DO NOT install the unit in a damp laundry room or near flammable gas. All units must be protected by a
certified electrical circuit breaker in accordance with all safety and electrical codes.
DO NOT use the system for anything other than what it was designed.
DO NOT store or install the units near food, paint, or other chemicals.
DO NOT use the unit in cool or dry mode for prolonged periods where humidity is higher than 90%.
DO NOT operate the unit for prolonged periods without refreshing ambient air. Open a door or window
periodically to allow in fresh air.
