Safety precautions
1.This air conditioner uses new refrigerant HFC (R410A).
2.Since the max. working pressure is 550 psig (3.8MPa) [R22:450 psig (R22:3.1MPa)], some of
the piping and installation and service tools are special.
3.This air conditioner uses power supply:208/230V ~, 60Hz.
4. The outdoor unit must be installed with indoor unit equipped with TXV and ensure that the
TXV can be opened to the maximum angle while running heating mode.
5. The outdoor unit must be matched with indoor unit with refrigerant R410A.
6. For 24K outdoor unit, it must be connected with 24K indoor unit.
For 36K outdoor unit, it can be connected with 36K indoor unit.
For 48K outdoor unit, it can be connected with 48K indoor unit.
For 60K outdoor unit, it can be connected with 60K indoor unit.
7. Specified filter drier is required on the liquid pipe when connecting the units.
8. Be sure that servicing equipment and replacement components are applicable for R-410A
refrigerant.
9. Do not discharge R410A refrigerant into the air, and when recover 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 detect HFC refrigerant.
11. R410A refrigerant is only compatible with POE oils, which could absorb moisture rapidly, so
do not expose it to the air, in case that it damages certain plastics materials.
12. Replace all the filter driers after maintenance.
Please read these SAFETY PRECAUTIONS carefully to ensure correct installation.
·Be sure to use a dedicated power circuit. 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. Definitions for identifying
hazard levels are provided below with their respective safety symbol.
WARNING：Hazards or unsafe practices which may result in severe personal injury or death.
CAUTION： Hazards or unsafe practices which may result in minor personal injury or product
or property damage.
·Please carefully file indoor and outdoor unit manual away for future reference.
·Installation should be performed by a qualified licensed service provider.
Improper installation may cause water leakage, electrical shock, or fire.
·Install the equipment on a solid base that can support the unit weight.
An inadequate base or incomplete installation may cause injury if the unit falls off the base.
·Use the specified type of wire to safely make electrical connections between the indoor and outdoor
units. Firmlyclamp the interconnecting wires so their terminals receive no external stresses.
·For wiring, use a cable long enough to cover the entire distance with no splicing. Do not connect
multiple devices to the same AC power supply. Exceeding the allowable current due to bad contact
or poor insulation, may cause fire or electric shock.
·After all installation is completed, check to make sure that there are no refrigerant leaks.
Refrigerant gas leakage in interior spaces will create harmful substances when exposed to heat or
flame.
·Perform the installation securely referring to the installation manual.
Incomplete installation may cause personal injury due to fire, electric shock, equipment falling, or
leakage of water.
·In accordance with the installation instructions for electrical work, please be sure to use a dedicated
line.
·If the power supply circuit capacity or electrical work is not in place, it may cause a fire or electric
shock.
·Secure electrical cover to indoor unit and service panel to outdoor unit.
