Daikin outdoor units are neat and sturdy and can be mounted easily
on a roof or terrace or simply placed against an outside wall.
•
The sevice valves are hidden inside the casing.
•
Outdoor units are fitted with a scroll compressor, renowned for low
noise and high energy efficiency.
•
A special acryl precoated fin for anti-corrosion treatment on the heat
exchanger ensures greater resistance against severe weather
conditions

Sound pressur e level is a r elative value, depending on the distance and acoustic environment. For mor e details,
please refer to sound level dr awings of this chapter.
The sound power level is an absolute value indicating the power which a sound source gener ates.
Sound values are measured in a semi- anechoic room.
In case of drain piping for outdoor unit, drain piping kit (option) is needed.
Nominal cooling capacities are based on : indoor temperature : 27° CDB, 19°CWB, outdoor temperature : 35° CDB,
equivalent refrigerant piping : 7.5m, level difference : 0m.
Nominal heating capacities are based on : indoor temperatur e : 20°CDB, outdoor temperature : 7°CDB, 6° CW B,
equivalent refrigerant piping : 7.5m, level difference : 0m

NOTES
1. RLA is based on the following conditions:
Indoor temp.: 27°CDB/19.5°CWB
Outdoor temp. : 35°CDB
2. TOCA means the total value of each OC set
3. Voltage range
Units are suitable for use on electrical systems where voltage
supplied to unit terminals is not below or above listed
operation range limits
4. Maximum allowable voltage unbalance between phases is 2%.
5. MCA/MFA
MCA = 1.25 x RLA + all FLA, MFA = < 2.25 x RLA + all FLA
(next lower standard fuse rating Min. 16A)
6. Select wire size based on the larger value of MCA or TOCA
7. Instead of fuse, use circuit breaker
8. For more details concerning conditional connections, see

Oil trap

Oil trap
Outdoor unit
Liquid piping
Install trap at each difference in eight of 15m
Gas piping
NOTE:
Since there is fear of the oil held inside the riser piping flowing back into the compressor when stopped and causing liquid
compression phenomenon, or cases of deterioration of oil return, it well be necessary to provide a trap at an appropriate
place in the riser gas piping.
A trap is not necessary when the outdoor unit is installed in a higher position than the indoor unit.

In these cases, close the
bottom of the installation
frame to prevent discharged
air from being bypassed.
In these cases, only 2 units can
be installed.
This situation is not allowed.
Figures between ( ) indicate
the dimensions only for the
100-125 class models.
B. Stacked installation
1. Obstacles exist in front of the outlet side
2. Obstacles exist in front of the air inlet
Do not stack more than one unit.
About 100mm is required as the dimension for laying the upper outdoor unit’s drain pipe.
Get the portion A sealed so that air from the outlet does not bypass.
C. Multiple-row installation
1. Installation of one unit per row
2. Installing multiple units (2 units or more) in
lateral connection per row
