There is risk of fire or electric shock.
Install the panel and the cover of control box securely.
There is risk of fire of electric shock.
Always install a dedicated circuit and breaker.
Improper wiring or installation may cause fore or electric shock.
Use the correctly rated breaker of fuse.
There is risk of fire or electric shock.
Do not modify or extend the power cable.
There is risk of fire or electric shock.
Do not install, remove, or reinstall the unit by yourself (customer).
There is risk of fire, electric shock, explosion, or injury.
Be caution when unpacking and installing the product.

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

HMF Series 5 Version - 0
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.)

Do not use the product for special purposes, such as preserving foods, works of art etc.
It is a consumer air conditioner, not a precision refrigerant system.
There is risk of damage or loss of property.
Do not block the inlet or outlet of air flow.
Use a soft cloth to clean. Do not use harsh detergents, solvents, etc.
There is risk of fire, electric shock, or damage to the plastic parts of the product.
Do not touch the metal parts of the product when removing the air filter. They are very
sharp.
Do not step on or put anything on the product. (outdoor units)
Always insert the filter securely. Clean the filter every two weeks or more often if
