 CAUTION

If children under 10 years old may approach the unit, take preventive measures so that 

they cannot reach the unit.

Keep the length of the piping of the indoor and outdoor units within the allowable range.
For maintenance purposes, do not bury the piping.

3.2. Drain installation

 

CAUTION

Perform drain work in accordance with this Manual, and ensure that the drain water is 

properly drained. If the drain work is not carried out correctly, water may drip down from 

the unit, wetting the furniture.
When the outdoor temperature is 0 °C or less, do not use the accessory drain pipe and 

drain cap. If the drain pipe and drain cap are used, the drain water in the pipe may freeze in 

extremely cold weather. (Reverse cycle model only)

As the drain water flows out of the outdoor unit during heating operation, install the 

 

drain pipe and connect it to a commercial 16 mm hose. (Reverse cycle model only)
When installing the drain pipe, plug all the holes other than the drain pipe mounting 

 

hole in the bottom of the outdoor unit with putty so there is no water leakage. (Reverse 

cycle model only)

3.3. Installation dimensions

 CAUTION

The installation space shown in the following examples is based on an ambient 

temperature under cooling operation of 35 °C (DB) at the air intake of the outdoor unit. 

Provide more space around the air intake than shown in the examples if the ambient 

temperature exceeds 35 °C (DB) or if the thermal load of all of the outdoor units exceeds 
the capacity.

Consider the transportation route, installation space, maintenance space, and access, 

and install the unit in a location with sufficient space for the refrigerant piping.
Observe the installation space specifications that are shown in the figures.

 

Keep the same space at rear air intake.

 

Provide the same space for the air intake at the rear of the outdoor unit.

 

If the installation is not performed according to the specifications, it could cause a short 

circuit and result in a lack of operating performance. As a result, the outdoor unit might 

easily be stopped by high-pressure protection.

3.3.2. Multiple outdoor unit installation

Provide at least 15 mm of space between the outdoor units if multiple units are 

 

installed.

When routing the piping from the side of an outdoor unit, provide space for the piping.

 

No more than 3 units must be installed side by side. When 3 units or more are 

 

arranged in a line, provide the space as shown in the following example 

when an 

obstruction is present also in the upward area
