Safety Precautions - Olmo OS-EAH36-230VO Installation Manual

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 euqipped 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 18K~24K indoor units.
For 36K outdoor unit, it can be connected with 30K~36K indoor units.
For 48K outdoor unit, it can be connected with 42K~48K indoor units.
For 60K outdoor unit, it can be connected with 42K~60K indoor units.
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, 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, because it contains
important safety issues. Definitions for identifying hazard levels are provide 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.
·Please carefully file indoor and outdoor unit manual away for future reference.
·Installation should be performed by a qualified personnel.
Improper installation may cause water leakage, electrical shock or fire.
·Install the air conditioner 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 for electrical connections safely between the indoor and outdoor units.
And firmly
clamp the interconnecting wires so their terminals receive no external stresses.
·For wiring, use a cable long enough to cover the entire distance with no connection.
And do not connect multiple devices to the same AC power supply.
Otherwise, it may be due to bad contact, poor insulation, exceed the allowable current and cause a
fire or electric shock.
·After all installation is completed, check to make sure that no refrigerant is leaking out.
If the refrigerant gas leakage to the interior, and the heater, stove flame touching it, will generate
harmful substances.
·Perform the installation securely referring to the installation manual.
Incomplete installation could cause a personal injury due to fire, electric shock, the unit 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, may cause a fire or electric shock.
·Attach the electrical cover to the indoor unit and the service panel to the outdoor unit securely.
