New Refrigerant Air Conditioner Installation
WARNING
THIS AIR CONDITIONER ADOPTS THE NEW HFC
REFRIGERANT(R410A)WHICH DOES NOT DESTROY OZONE
LAYER.
The characteristics of R410A refrigerant are; Hydrophilic, oxid-
izing membrane or oil, and its pressure is approx.1.6 times high-
er than that of refrigerant R22.Accompanied with the new refrig-
erant, refrigerating oil has also been changed ,Therefore, during
installation work, be sure that water, dust, former refrigerant, or
refrigerating oil does not enter the refrigerating cycle.
To prevent charging an incorrect refrigerant and refrigerating oil,
the sizes of connecting sections of charging port of the main
unit and installation tools are charged from those for the
conventional refrigerant.
Accordingly the exclusive tools are required for the new
refrigerant (R410A):
For connecting pipes, use new and clean piping designed for
R410A,and please care so that water or dust does not enter.
Moreover, do not use the existing piping because there are
problems with pressure-resistance force and impurity in it.
CAUTION
Do not connect the Appliance from Main Power Supply.
This unit must be connected to the main power supply by
means of a switch with a contact separation of at least 3 mm.
The installation fuse must be used for the power supply line of
this conditioner.

Confirm the critical thickness through follow steps, and take
necessary actions.
1. Calculate the sum of the charge volume (A[kg]) Total
Refrigerant volume of 10HP=factory refrigerant
volume + superaddition
2. Calculate the indoor cubage (B[m ]) (as the minimum
cubage.

3. Calculate the refrigerant thickness
≤critical thickness
Counter measure against over high thickness
1. Installmechanicalventilator to reduce the refrigerant thickness
under critical level. (ventilate regularly)
2. Install leak alarm facility related to mechanical ventilator if
you can not regularly ventilate.
