condenser and evaporator.
For installation, always contact the dealer or an authorized service center.
Do not install the product on a defective installation stand.
Be sure the installation area does not deteriorate with age.
If the base collapses, the air conditioner could fall with it, causing property damage, product failure,
and personal injury.
Do not let the air conditioner run for a long time when the humidity is very high and a
door or a window is left open.
Take care to ensure that power cable could not be pulled out or damaged during
operation.
There is risk of fire or electric shock.
Do not place anything on the power cable.
There is risk of fire or electric shock.
Do not plug or unplug the power supply plug during operation.
There is risk of fire or electric shock.
Do not touch (operation) the product with wet hands.
Do not place a heater or other appliance near the power cable.
There is risk of fire and electric shock.
Do not allow water to run into electrical parts.
It may cause fire, failure of the product, or electric shock.
Do not store or use flammable gas or combustible near the product.
There is risk of fire or failure of product.
Do not use the product in a tightly closed space for a long time.
Oxygen deficiency could occur.
When flammable gas leaks, turn off the gas and open a window for ventilation before
turn the product on.
If strange sounds or smoke comes from product, turn the breaker off or disconnect the
power supply cable.
There is risk of electric shock or fire.
Stop operation and close the window in storm or hurricane. If possible, remove the
PRECAUTION
HKD DCI 5 Version - 1
product from the window before the hurricane arrives.
There is risk of property damage, failure of product, or electric shock.
Do not open the inlet grill of the product during operation. (Do not touch the electrostatic
filter, if the unit is so equipped.)
There is risk of physical injury, electric shock, or product failure.
When the product is soaked, contact an authorized service center.
There is risk of fire or electric shock.
Be caution that water could not enter the product.

Turn the main power off when cleaning or maintaining the product.
There is risk of electric shock.
When the product is not be used for a long time, disconnect the power supply plug or
turn off the breaker.
There is risk of product damage or failure, or unintended operation.
Take care to ensure that nobody could step on or fall onto the outdoor unit.
This could result in personal injury and product damage.
CAUTION
Always check for gas (refrigerant) leakage after installation or repair of product.
Low refrigerant levels may cause failure of product.
Install the drain hose to ensure that water is drained away properly.
A bad connection may cause water leakage.
Keep level even when installing the product.
It can avoid vibration of water leakage.
