Safety Precautions
1. Safety Precautions
Installing, starting up, and servicing air conditioner can behazardous due to system pressure, electrical components, and
equipment location, etc.Only trained, qualified installers and service personnel areallowed to install, start-up, and service this
equipment.Untrained personnel can perform basic maintenance fun-ctions such as cleaning coils. All other operations should be
performed by trained service personnel.When handling the equipment, observe precautions in themanual and on tags, stickers,
and labels attached to theequipment. Follow all safety codes. Wear safety glasses andwork gloves. Keep quenching cloth
and fire extinguisher nearby when brazing.Read the instructions thoroughly and follow all warnings orcautions in literature and
attached to the unit. Consult localbuilding codes and current editions of national as well as local electrical codes.
Recognize the following safety information:
◆ Make sure the outdoor unit is installed on a stable, level surface with no accumulation of snow, leaves, or trash beside.
◆ Make sure the ceiling/wall is strong enough to bear the weight of the unit.
◆ Make sure the noise of the outdoor unit does not disturb neighbors.
◆ Follow all the installation instructions to minimize the risk of damage from earth quakes, typhoons or strong winds.
◆ Avoid contact between refrigerant and fire as it generate spoi onous gas.
◆ Apply specified refrigerant onl . Never have it mixed with any other refrigerant. Never have air remain in the refrigerant line as
it may lead to rupture and other hazards.
◆ Make sure no refrigerant gas is leaking out when installation is completed.
◆ Should there be refrigerant leakage, the density of refrigerant in the air shall in no way exceed its limited value, or it may lead
to explosion.
◆ Keep your fingers and clothing away from any moving parts
◆ Clear the site after installation. Make sure no foreign objects are left in the unit.
◆ Always ensure effective grounding for the unit.
Incorrect handling could result inpersonal injury or death. Incorrect handling may result inminor injury,or damage to product
or property.
Warning Caution
Warning Caution
All electric work must be performed by a licensed technician
according to local regulations and the instructions given in
this manual.
Before installing, modifying, or servicing system,
mainelectrical disconnect switch must be in the OFF position.
There may be more than 1 disconnect switch. Lock out and
tag switch with a suitable warning label.
Never supply power to the unit unless all wiring and tubing
are completed, reconnected and checked.
This system adopts highly dangerous electrical voltage.
Incorrect connection or inadequate grounding can cause
personal injury or death. Stick to the wiring diagram and all
the instructions when wiring.
Have the unit adequately grounded in accordance with local
electrical codes.
Have all wiring connected tightly. Loose connection may lead
to overheating and a possible fire hazard
All installation or repair work shall be performed by your
dealer or a specialized subcontractor as there is the risk of
fire, electric shock, explosion or injur .
Never install the unit in a place where a combustible gas
might leak, or it may lead to fire or explosion
Make a proper provision against noise when the unit is
installed at a telecommunication center or hospital.
Provide an electric leak breaker when it is installed in a
watery place.
Never wash the unit with water.
Handle unit transportation with care. The unit should not be
carried by only one person if it is more than 20kg.
Never touch the heat exchanger fins with bare hands
Never touch the compressor or refrigerant piping without
wearing glove.
Do not have the unit operate without air filte .
Should any emergency occur, stop the unit and disconnect
the power immediately.
Properly insulate any tubing running inside the room to
prevent the water from damaging the wall.

Use vacuum pump
1. Remove the valve caps on the liquid valve and gas valve and
the nut of refrigerant charging vent.
2. Connect the charging hose of piezometer to the refrigerant
charging vent of gas valve and then connect the other charging
hose to the vacuum pump.
3. Open the piezometer completely and operate for 10-15min to
check if the pressure of piezometer remains in -0.1MPa.
4. Close the vacuum pump and maintain this status for 1-2min to
check if the pressure of piezometer remains in -0.1MPa. If the
pressure decreases, there may be leakage.
5. Remove the piezometer, open the valve core of liquid valve and
gas valve completely with inner hexagon spanner.
6. Tighten the screw caps of valve and refrigerant charging vent.
7. Reinstall the handle.
1. With leakage detector:
Check if there is leakage with leakage detector.
2. With soap water:
If leakage detector is not available, please use soap water for leakage detection.Apply soap water at the suspected position and
keep the soap water for more than 3min. If there are air bubbles coming out of this position, there's a leakage.
