Introduction
Domestic air conditioner
Warning
Be sure to use an exclusive power circuit for the equipment, and follow the technical standards related to
the electrical equipment, the internal wiring regulations and the instruction manual for installation when
conducting electrical work.
Insufficient power circuit capacity and improper electrical work can cause an electrical shock or fire.
Be sure to use the specified cable to connect between the indoor and outdoor units. Make the
connections securely and route the cable properly so that there is no force pulling the cable at the
connection terminals.
Improper connections can cause excessive heat generation or fire.
When connecting the cable between the indoor and outdoor units, make sure that the terminal cover
does
not lift off or dismount because of the cable.
If the cover is not mounted properly, the terminal connection section can cause an electrical shock,
excessive heat generation or fire.
Do not damage or modify the power cable.
Damaged or modified power cable can cause an electrical shock or fire. Placing heavy items on the
power cable, and heating or pulling the power cable can damage the cable.
Do not mix air or gas other than the specified refrigerant (R-410A / R22) in the refrigerant system.
If air enters the cooling system, an excessively high pressure results, causing equipment damage
and injury.
If the refrigerant gas leaks, be sure to locate the leak and repair it before charging the refrigerant. After
charging refrigerant, make sure that there is no refrigerant leak.
If the leak cannot be located and the repair work must be stopped, be sure to perform pump-down and
close the service valve, to prevent the refrigerant gas from leaking into the room. The refrigerant gas
itself
is harmless, but it can generate toxic gases when it contacts flames, such as fan and other heaters,
stoves and ranges.
.
When replacing the coin battery in the remote controller, be sure to disposed of the old battery to prevent
children from swallowing it.
If a child swallows the coin battery, see a doctor immediately.
Caution
Installation of a leakage breaker is necessary in some cases depending on the conditions of the

7.1.5.5˖Temperature protection of the outdoor refrigerating coil
When the defrosting temperature and the sensor’s temperature are higher than 68ć, the frequency of the
compressor decreases 1hz/10seconds. Keep the frequency until it decreases to the lowest frequency. When
the temperatures are lower than 68ć and higher than 61ć, keep the frequency of the compressor. When
the temperatures are lower than 61ć, relieve the defrosting temperature protection.

To bend a pipe, give the roundness as large as possible not to crush the pipe ,
and the bending radius should be 30 to 40
mm or longer.
Connecting the pipe of gas side
rst makes working easier.
The connection pipe is specialized for R410A.
Use the same method on indoor unit. Loosen the screws on
terminal block and
insert the plugs fully into terminal block, then tighten the screws.
Insert the cable according to terminal number in the same manner as the indoor
unit.
If wiring is not correct, proper operation can not be carried out and controller
may be damaged.

CAUTION
Be careful that matters, such as wastes of sands, etc. shall not enter the pipe.
The standard pipe length is 5m. If it is over 7m, the function of the unit will be
affected. If the pipe has to be lengthened, the refrigerant should be charged,
according to 20 g/m. But the charge of refrigerant must
be conducted by profes-
sional air conditioner engineer. Before adding additional refrigerant, perform air
purging from the refrigerant pipes and indoor unit using a vacuum pump,then
