Safety Precautions
D WARNING —There will be a risk of serious damage to the air conditioning unit or casualty if
the manual is not strictly followed.
D NOTICE —If the manual is not strictly followed, there will be a risk of light or moderate damage
to the air conditioning unit, property damage, personal injury or environmental
pollution. It also provides useful help information which may be beneficial to the
operation of the unit or to the service life extension of the unit. However, it does not
indicate that the help information is optimal or directly related to the improvement
of unit operation.
D WARNINGS
• All installation procedures of the air-conditioning unit shall conform to the national and local regulations.
• For the installation of the equipment, please consult with the local sales office. Professional technicians with the
installation certificate of air conditioning unit shall be required to install the air conditioning unit. Users shall not
install, repair or move the air conditioning unit. If the users construct by themselves, leakage, electric shock or fire
may be caused.
• Before installation or maintenance, lock the power supply and the cut-off switch of the unit in the power-off state
to avoid personal injury caused by electric shock or contact with a moving part.
• Please set up a dedicated circuit.The fluctuation of voltage supply shall not exceed 10% of the rated voltage.The
power supply line must be separated from the welding transformer, which will cause large voltage fluctuation.
• Professional electricians with certificates shall be required to strictly carry out installation operations in accordance
with the national power standards and the regulations of the local power department, inspect whether the line
capacity meets the requirements and whether the power line is loose or damaged.
• The cover plate of the electric cabinet must be firmly installed to prevent dust, water and other foreign matters
from entering.The electrical part must be moisture-proof and away from water source, or it will cause electric
shock, fire and other accidents.
• Please use the fuse with correct current strength. Do not use temporary substitutes, such as a piece of wire.This
may not only damage the unit itself, but also cause fire.
• The power supply and electric auxiliary heating power supply of the unit must be equipped with leakage
protection devices, and the earth wire must be connected, otherwise there will be injuries or even casualties and
other accidents in the absence of protection.
• All electric auxiliary heating wires shall be connected in accordance with the wiring diagram. Directly energizing
the electric auxiliary heating wires will lead to the failure of some control functions of the unit and damage the
unit.
• Please strictly follow the wiring diagram in this manual. Incorrect wiring or manual wiring change will cause unit
failure, damage or personal safety.
• When cleaning the unit, do not sprinkle water directly on the unit, which may cause electric shock.
• Cut off all power supplies before contacting the wiring device.
• Before maintenance, please confirm that the unit is in the power-off state.
• Maintenance can only be carried out by professional maintenance personnel. For maintenance and repair, contact
Trane sales office. Improper maintenance and repair may result in water leakage, electric shock or fire.
• Do not use flammable materials (e.g. hairspray or pesticides) near this product. Do not clean the product with
organic solvents such as paint thinner.
• Cracks, electric shock or fire may be caused if organic solvents are used.
• Optional accessories shall be installed by professionals. Be sure to use the optional accessories designated by the
company. Improper.
• Do not use unqualified refrigerants, refrigerant substitutes or refrigerant additives. Incorrect use method or use of

4 PKGP-SVX18B-EN
unqualified refrigerants, refrigerant substitutes or refrigerant additives will cause damage to the unit and various
safety risks. Please select qualified refrigerant or call 8008208676 to purchase qualified refrigerant. All technicians
operating refrigerants must be certified, and be familiar with and strictly comply with the relevant technical
requirements, laws and regulations regarding the use, handling, recovery and recycling of refrigerants.
• No open flames are allowed when the refrigerant leaks. If the air conditioning unit fails to refrigerate or heat
properly, the refrigerant may leak. ContactTrane sales office at this time.
• The refrigerant used in the air conditioning unit and will not leak in normal conditions. In case of indoor refrigerant
leakage, toxic gases will be produced after the refrigerant is in contact with the flame of heater, electric furnace
and stove. Please extinguish the fire of the burning appliances, ventilate the room and contactTrane sales office.
• When the unit is repaired in case of refrigerant leakage, please operate the machine after the maintenance
personnel confirm that the leakage repair is completed.
• Do not start the air conditioning unit when the panel or protective net is removed. Rotating parts in the air
conditioning unit may injure people or other articles.
• Prevent objects, such as sticks, sand or stones, from entering the air inlet or outlet grid.The fan rotates at high
speed and is very dangerous. Special care must be taken of children.
• The strength of ordinary air conditioner support may not be suitable for this product. Please choose the support
according to the weight design of the unit.The support with insufficient bearing strength will cause great safety
accidents and hidden dangers.
• In the seasons with frequent use of air conditioning unit and if the machine stops using for a short period of time
in winter, please keep the machine in the power-on state to ensure that the machine can be normally ant freezing.
Otherwise, the machine may be frozen to be out of service.
• If the system is powered on for the first time or used after the power supply is cut off for a long time, it shall be
powered on for 24 hours before starting up, so as to ensure that the unit is fully preheated, otherwise it may cause
the burning of compressor.
• In the season when the air conditioning unit is not used for a long time, please cut off the main power supply of
the system to extend the service life of the unit and save electrical energy.
D NOTICES
• Do not touch the fins of the heat exchanger. Otherwise, it may damage the fins to cause the reduction of machine
performance or cut fingers.
• After the installation, the air tightness test shall be carried out on the pipeline to check whether the pipeline leaks.
• Do not touch the refrigerant pipeline during or immediately after the operation of the unit. When the air
conditioning unit runs, the pipeline may be very hot or cold, leading to burn or frostbite.
• Do not sit on the direct air duct for a long time. Long-time sitting on the direct air port not good for your health.
Special attention should be paid when you sleep or there is an infant, the elderly or the sick in the room.
• Do not place the heating device or other heat sources under or near the air conditioning unit.The machine body
will be deformed after being heated.
• Whenever you operate the unit, make sure the air filter is properly installed. Otherwise, dirt may enter into the
internal moving parts and cause damage.
• Do not block or cover the inlet or outlet grid.This may cause performance degradation and affect the normal
running ability.
• The chassis of the outdoor unit is provided with a defrosting waterspout ensure the smooth water drainage of the
unit.
• It is recommended that the snow shade be installed for the outdoor unit to ensure the better operation of the
machine on snowy days. installation may cause water leakage, electric shock and fire.

and Instructions
Ensue safety.
Handle with care.
Inspection before hoisting
Hoisting
1. Inspect whether the unit periphery and the
fixed parts are intact.
2. Inspect whether the unit and the packaging
baseplate are intact.
Suggestion: remove the packaging baseplate to
hoist for fear of drop.
1. Hoisting operation shall be performed by the personnel
with hoisting qualification.
2. Thread the sling into 4 lifting eyes at the top of the unit.
3. The sling shall have enough capacity of bearing the unit weight.
4. The sling tying length shall be suitable, and the sling lifting angle
shall be more than 45 degrees.
D Warning
During hoisting, ensure stable hoisting of the outdoor unit, and avoid uneven weight distribution of the unit. If the
center of gravity is on the side of the compressor, trial operation should be performed before hoisting. Observe
whether the sling is tied tightly and whether the unit is at the risk of toppling. When hoisting, rise slowly and evenly
to prevent the unit from tipping over and ensure the safety of people around!
