Select the Installation Location for CYB-20 Ceiling Cassette Indoor & Outdoor UnitsUpdated a day ago
Introduction
This article outlines the criteria for selecting the installation sites for CYB-20 ceiling cassette indoor and outdoor units.
Prior to installation, we recommend understanding the guidelines for selecting ideal locations for the indoor and outdoor units. The following are standards intended to help select appropriate locations for the units.
Indoor Unit
Proper installation locations for the indoor unit must ensure the following standards:
- Sufficient space for installation and maintenance.
- Sufficient space to connect the pipes and drainpipe.
- No direct radiation from heaters.
- The air inlet and outlet are not blocked.
- The airflow can fill the entire room.
- The ceiling is horizontal and its structure can sustain the indoor unit's weight.
Do not install the indoor unit in the following locations:
- Areas with oil drilling or fracking.
- Coastal areas with high salt content in the air.
- Areas with caustic gases in the air, such as near hot springs.
- Areas that experience power fluctuations, such as factories.
- Enclosed spaces, such as cabinets.
- Kitchens that use natural gas.
- Areas with strong electromagnetic waves.
- Areas that store flammable materials or gas.
- Rooms with high humidity, such as bathrooms or laundry rooms.
Recommended distance between the indoor unit and ceiling:


| Capacity (BTU/h) | A | B | H |
| 36K | 9-5/8 in (245 mm) | 2-ft, 11-3/8-in / 35-3/8 in (900 mm) | > 10-3/4 in (271 mm) |
| 48K | 11-1/4 in (287 mm) | > 12-1/4 in (313 mm) |
Outdoor Unit
Proper installation locations for the outdoor unit must ensure the following standards:
- The installation's spatial requirements shown in the illustration are met.

- The location is solid enough to support the unit and prevent vibration.
- Sufficient air circulation and ventilation.
- Noise from the unit will not disturb other people.
- The location is protected against prolonged exposure to direct sunlight or precipitation.
- The location is protected against ice buildup and coil damage during snowfall.
Do not install the indoor unit in the following locations:
- Near an obstacle that will block air inlets and outlets.
- Near public streets, crowded areas, or places where noise from the unit will disturb others.
- Near animals or plants that will be harmed by hot air discharge.
- Near any source of combustible gas.
- A location that is exposed to large amounts of dust.
- A location exposed to an excessive amount of salty air.
Special considerations for extreme weather:
- If the outdoor unit is exposed to strong wind: Install the unit so that the air outlet fan is at a 90-degree angle to the wind direction. If necessary, build a barrier in front of the unit to protect it from extremely strong winds.
- If the outdoor unit is frequently exposed to heavy rain or snow: Build a shelter above the unit to protect it from rain or snow, ensuring the airflow is not obstructed.
- If the outdoor unit is frequently exposed to salty air (seaside): Use an outdoor unit specifically designed for corrosion resistance.
