Safety Precautions
1.
This air conditioner uses refrigerant HFC (R410A).
2.
Since the max. working pressure is 550 PSIG (3.8MPa) [R22:450 PSIG (R22:3.1MPa)], some
of the piping, installation, and service tools may be uncommon.
3.
This air conditioner uses a power supply of: 208/230V, 60Hz, 1Ph.
4.
The outdoor unit must be matched with an indoor unit equipped with a TXV that can be
conducted in heating mode.
5.
The outdoor unit must be matched with an indoor unit using refrigerant R410A.
6.
For the 24K outdoor unit, it can be connected with 18K~24K indoor units.
For the 36K outdoor unit, it can be connected with 30K~36K indoor units.
7.
A specified filter drier is required on the liquid pipe when connecting the units.
8.
Be sure that the servicing equipment and replacement components are applicable for
R410A refrigerant.
9.
Do not discharge R410A refrigerant into the air, and when recovering it, the cylinder service
pressure rating must be over 550 PSIG. R410A refrigerant systems should be charged with
liquid refrigerant, and the service pressure rating of the hoses used must be over 750 PSIG.
10. Leak detectors should be designed to be able to detect HFC refrigerant.
11. R410A refrigerant is only compatible with POE oils, which absorb moisture rapidly. Do not
expose it to the air, as this could cause damage to certain plastics materials.
12. Replace all filter driers after completion of maintenance.
·Be sure to use a dedicated power circuit, and do not put other loads on the power supply.
·Be sure to read these SAFETY PRECAUTIONS carefully before installation.
·Be sure to comply with SAFETY PRECAUTIONS of installation manual, since it contains important
safety instructions. Definitions for identifying hazard levels are provided below with their respective
safety symbols.
WARNING：Hazards or unsafe practices which COULD result in severe personal injury or death.
CAUTION： Hazards or unsafe practices which COULD result in minor personal injury or product
or property damage.
·Carefully store the indoor and outdoor unit manuals away for your future reference.
·Installation should be performed only by qualified personnel.
Improper installation can cause water leakage, electrical shock, or fire.
·Install the air conditioner on a solid base that can support all of the unit's weight.
An inadequate base or incomplete installation may cause injury if the unit falls off the base.
·Use the specified type of wire for electrical connections safely between the indoor and outdoor units.
Firmlyclamp the interconnecting wires so that their terminals can receive no external stresses.
·For wiring, use a cable long enough to cover the entire distance with no connection.
Do not connect multiple devices to the same AC power supply.
Otherwise, there is risk that due to bad contact or poor insulation, it can exceed the allowable current
and cause a fire or electric shock.
·After installation is complete, perform a leak check to make sure that no refrigerant is leaking out.
If the refrigerant gas leaks internally, toward the heater, or externally towards any stove flames, it can
generate harmful substances.
·Perform the installation securely referring to the installation manual.
Incomplete installation could cause personal injury due to fire, electric shock, the unit falling, or
leakage of water.
·In accordance with installation instructions for electrical-related work, use a dedicated electrical line.
·If the power supply circuit capacity/electrical work is not proper, it may cause a fire or electric shock.
·Attach the electrical cover to the indoor unit and the service panel to the outdoor unit securely.
·If the electrical covers on the indoor unit or the service panel of the outdoor unit are not attached
securely, it could result in a fire, or an electric shock due to dust, water, etc.
