NOTES
1 The sound pressure level is measured via a microphone at a certain distance from the unit. It is a relative value, depending on the distance and
acoustic environment. For measuring conditions: please refer to item 8 of this chapter.
2 The sound power level is an absolute value indicating the ’’power’’ which a sound source generates.

SYMBOLS
AFR : Air flow rate (m

/min)
BF : Bypass factor
EWB : Entering wet bulb temp. (°CWB)
EDB : Entering dry bulb temp. (°CDB)
TC : Total cooling capacity (kW)
SHC : Sensible heating capacity (kW)
PI : Power input (kW)
Caution:
TC and SHC are shown by kW
NOTES
1 Ratings shown are net capacities which include a deduction for
indoor fan motor heat
2 shows nominal (rated) capacities and power input.
3 TC, PI and SHC must be calculated by interpolation using the figures
in the above tables. (Figures out of the tables should not be used for
calculation.)
4 SHC is based on each EWB and EDB
SHC* = SHC correction for other dry bulb
= 0.02*AFR (m
3
/min.)*(1-BF)*(DB*-EDB)
Add SHC* to SHC.
5 Capacities are based on following conditions:
Corresponding refrigerant piping length: 7.5 m
Level difference: 0 m
6 Air flow rate (AFR) and Bypass factor (BF) are taburated above.

Max. allowable length 20 m
Max. allowable height 15m
Additional refrigerant required
for refrigerant pipe exceeding
10 m in length. 20 g/m
Gas pipe O.D. 9.5 mm
Liquid pipe O.D. 6.4 mm
* Be sure to add the proper amount of additional refrigerant.
Failure to do so may result in reduced performance.
In sites with poor drainage, use block
bases for outdoor unit. Adjust foot
height until the unit is leveled.
Otherwise, water leakage or pooling of
water may occur. Where there is a danger of the unit falling,
use foot bolts, or wires.
Allow space for piping and electrical
servicing.
Service lid
How to remove the service lid.
+ This service lid is an open/close type.
+ Slide the lid downward to remove it.
How to attach the service lid.
+ Insert the upper part of the service lid
into the outdoor unit to install.
+ Tighten the screws.
