DANGER
!
Before reading the installation manual, please do not conduct installation works such as connections
•
of refrigerant piping, condensate pipes and wiring. Any violation may lead to system leakage, electrical
failure or fire.
Do not pour water into the indoor/outdoor unit. This product contains electrical components and if wet,
•
can cause serious electrical shock.
Opening the indoor unit's maintenance cover without disconnecting the main power supply may lead
•
to fatal accident.
Tamper with or adjusting the indoor unit's safety device may lead to serious accident.
•
Use the ELB (Earth Leakage Breaker)
•
breaker, action time of 0.1s or less). Otherwise, it may lead to electric shock or fire.
During installation, refrigerant pipes must be securely connected before compressor starts running.
•
During maintenance, refrigerant pipes must be moved, handled, and removed only after the compressor
stops running.
When the machine is running, please do not short-circuit the protection device (such as pressure switch).
•
Otherwise, it may cause fire or explosion.
Do not install pipe work with diameters that are not specified for that model.
•
Do not ground units to water pipes, gas pipes, telephone wires, or lightning rods as incomplete
•
grounding can cause a severe shock hazard resulting in severe injury or death. Additionally, grounding
to gas pipes could cause a gas leak and potential explosion causing severe injury or death.
Do not install unit in an area where flammable materials are present due to risk of explosions that can
•
cause serious injury or death.
Safely dispose all packing and transportation materials in accordance with federal/state/local laws or
•
ordinances. Packing materials such as nails and other metal or wood parts, including plastic packing
materials used for transportation may cause injuries or death by suffocation.
Refrigerant gas is heavier than air and replaces oxygen. A massive leak can lead to oxygen depletion,
•
especially in basements, and an asphyxiation hazard could occur leading to serious injury or death.
If refrigerant gas leaks during installation, ventilate the area immediately. Refrigerant gas may produce
•
toxic gas if it comes into contact with fire. Exposure to this gas could cause severe injury or death.
WARNING
!
Do not use sprays such as pesticide, oil paint, hair spray or other flammable gases within 3.3ft(1m) of
•
the machine.
If the circuit breaker trips frequently, stop the system and contact local dealer or service provider.
•
Ensure if the grounding wires are securely connected. Incorrect grounding may lead to electrical failure
•
of the machine.
Before brazing, ensure no flammable materials are placed in the periphery. Before charging refrigerant,
•
wear leather gloves to prevent injury due to freezing.
Wiring and electrical elements shall be protected from being damaged by rats or other animals.
•
Damages(caused by bites) on the unprotected part may lead to fire.
Ensure the wires are connected firm and secure. External forces on the wiring terminal may loosen such
•
terminals and lead to fire.
Install the air conditioner on surfaces with sufficient strength to withstand the load. Otherwise, the air
•
conditioner may topple and fall causing machine damage or personal injuries.
Before turning on the system, ensure that the outdoor unit is not covered by snow or ice.
•
Assure that the maximum operating pressure is checked when connecting to Outdoor UNIT.
•
This unit <PPIM-UFA1DQ> is a PARTIAL UNIT AIR CONDITIONER, shall only be connected to an appliance
•
which is above medium reaction speed (residual-current circuit
