Safety

•  This manual should be saved and stored close to this air conditioning equipment.

•  There are two types if indications. Both are related to safety and should be strictly followed. "Warning" highlights issues that pose a risk of major injury or death. " Caution" highlights issues that pose a risk of equipment or bodily injury.

•  After installation and start-up commissioning, please give the manual to the user. The manual should be kept in safe place and close to the unit.

WARNING

•  Installation and maintenance should be performed by an authorized agency. The wrong operation of this air condition equipment may cause water damage, electric shock or fire.

•  Please install the unit on the top of a solid foundation or structure which is strong enough to support the unit. •  The installation of this condition equipment should follow local building codes.

•  Use the right cable size, secure the terminal firmly, organize the cables well and make sure no tension is added on cables. Cable insulation should not be damaged. Improper wire installation may lead to fire.

•  This unit is only compatible with R-410A refrigerant. If any other gas enters the system, it may lead to abnormal high pressure which may cause damage or injury.

•  Only use branches supplied by Haier. Use of any other branches will void warranty.

•  Keep the condensate drain pipe away from toxic gas vents to prevent possible pollution of indoor environment.

•  Care should be taken to ensure that there are no refrigerant leaks. R-410A is a heavy gas and will displace oxygen. Ventilate the area if a leak if found.

•  The unit is not explosion-proof. Please keep it away from flammable gases.

•  The drain pipe should be installed per this manual to ensure proper drainage. The pipe should be well insulated to avoid condensation. Wrong installation may lead to water damage.

•  Both liquid pipe and the vapor pipe should be also well insulated. Not enough insulation may lead to system performance deterioration or condensate formation.

•  This equipment should not be used or serviced by personnel who have not been properly trained in its operation and maintenance.

•  Children should be supervised to ensure that they do not play on or near the equipment. •  Keep the appliance and its cord out of reach of children.

•  The appliances are not intended to be operated by means of an external timer or separate remote-control system.

CAUTION

•  Grounding wire should be connected to the grounding bar. The grounding wire cannot be connected to the gas pipe, water pipe, lightening rod or the telephone grounding wire. Improper grounding may cause electric shock.

•  A circuit breaker should be installed. If not, it may cause electric shocks or accidents.

•  After installation, the air condition equipment should be powered on and passed the electric leakage current lest.

•  If the ambient humidity is more than 80%, if the water discharge hole is blocked or the filter becomes dirty or the airflow speed changes, this may lead to condensate water leaks. There may also be some drops of water spraying out.
