High External Static Pressure
High External Static Pressure 35Pa
When unit is installed on a narrow balcony and exposed to the sun, the fence at the front side would restrict hot air from being discharged. Heat accumulated in an enclosure can cause over-heating. This could potentially result in damage or shorten the product’s life span. A high external static pressure sends the air further away from the outdoor unit and through the fence. This provides better air circulation and distribution.
Higher Pressure than Previous Model
When the pressure is low, hot air will accumulate in the unit thus affecting its work performance and of the unit above it as well. But with a high pressure of 35 Pa, hot air is sent further away preventing overheating inside the outdoor unit enclosure.
New Fan for Efficient Hot Air Discharge
High electrostatic pressure disrupted the airflow of the previous fan, lowering the air pressure and preventing hot air from being discharged far enough. The new LE Series fan has ribs extending near the blade tips, in a structure that resists deformation. During high electrostatic pressure, this blade shape suppresses disruptions in the airflow, and a high air pressure of 35 Pa discharges the hot air at a sufficient distance.
Variable Evaporation Temperature for Energy Saving and Comfortable Air Conditioning
Since 2006, all Panasonic VRF systems have included special VET technology, with variable refrigerant temperature, as standard.
1. Feedback room temperature and set temperature every 30 seconds.
2. Determine system refrigerant temperature and control compressor speed.
3. Calculate indoor refrigerant temperature and control the airflow automatically based on the difference between the set temperature and the actual indoor temperature.

*A 50 m piping length is sufficient for most residential and small business buildings. When the total piping length exceeds 50 m, an additional refrigerant charge is required. **Actual length: 150 m.
Easy-to-Install Design
Compact Design
Since Mini-FSV LE Series is a single unit, it is possible to install the unit in more varied places compared to the Single Split system.
Short Height of 996 mm (LE2)
In addition to raising efficiency, we have made the outdoor unit more compact. It can now be installed in places that were previously too small.
Up to 13 Indoor Units Connectable
An expansion from the Panasonic FSV lineup, the Mini-FSV is compatible with the same indoor units and controls as the rest of the FSV range.
Note: Use any of the 22 types of indoor models. Depending on the size or type of indoor unit, the tubing size shall be changed. Please refer to manuals for details. Diversity ratio 50-130%. 6 HP for 9 units, 4 HP for 7 units, 5 HP for 8 units.
High Efficiency
High Efficiency
The operation efficiency has been improved using a highly efficient R410A refrigerant, a DC Inverter compressor, a DC motor, and a heat exchanger design.
Energy Savings Design
1. Panasonic’s inverter compressor to improve partial-load capacity.
2. 2 pieces of the printed circuit board for easy maintenance.
3. Large-size accumulator to maintain compressor reliability for extended max piping length.
4. DC fan motor for optimum air volume.
5. Newly designed fan blades to inhibit air turbulence and increase efficiency.
6. Redesigned heat exchanger & copper tubes to increase efficiency.
7. Centrifugal oil separator improves oil separation efficiency and reduces refrigerant pressure loss.

High Durability
Wide Operating Range
Cooling operation is possible even when the outdoor temperature is as low as -10°C DB or as high as 46°C DB. As for heating operation, it is possible even when the outdoor temperature is as low as -20°C WB. The remote controller temperature can be set from 18°C up to 30°C (cooling), 16°C up to 30°C (heating)*.
*Depending on the type of remote controller.
Note: For further information please refer to the capacity tables in the Technical Data Book.

Blue Fin Condenser
The anti-corrosion Blue Fin treatment of the heat exchanger provides greater resistance against corrosion. All models are equipped with a Blue Fin condenser.
Quiet Operation Mode
Quiet operation mode reduces outdoor unit operating sound down to 7 dB than rating. 3-step set point is available. External input signal is also available.
Note: Quiet Operation Mode timer setting is available with high-spec Remote Controller (CZ-RTC5B/CZ-RTC6 series).
Flexible Demand Response
Simple Demand Respose
Featuring inverter control technology, all Panasonic Mini FSV systems are Demand Response Management (DRM) ready. With this control, power consumption at times of peak load can be set in three steps to deliver optimum performance. This helps to reduce annual power consumption with minimal loss in comfort.
Demand control terminal is available to control 0-50-75-100% of capacities.
Demand control terminal is available to control 0-50-75-100% of capacities.
Note: CZ-CAPDC3 to be supplied separately.
Flexible Demand Response
The setting is possible as 0% or in the range from 40 to 100% (in steps of 5%). At the time of shipping, the setting has been done to the three steps of 0%, 70%, and 100%.
Note: Terminal block CZ-CAPDC2 is to be supplied separately. Demand timer setting for high-spec remote controller is available.
