NOTE
* Specifications may be subject to change without prior notice for product improvement.
* 1) Nominal heating capacities are based on;
Water temperature : 86°F(30°C) inlet, 95°F(35°C) outlet
Indoor temperature : 68°F(20°C) DB
Outdoor temperature :44.6°F(7°C) DB, 42.8°F(6°C) WB
* 2) Sound pressure was acquired in an anechoic room. Thus actual noise level may be different depending on the installation conditions.
* 3) The VRF system contains R410A (GWP=2,088) which is fluorinated greenhouse gas.
* Heat Exchanger type : Plate Heat Exchanger (STS)

How to calculate heating capacity power input : Combination of outdoor unit and hydro unit HT
- Heating capacity and power input of hydro unit HT : refer to the indoor unit capacity table.
- Power input of outdoor unit : refer to the Outdoor unit capacity table (indoor 68℉ DB).
Example
- Standard condition : Outdoor 44.6℉ DB/42.8℉ WB, Indoor 68℉ DB
- Water condition : EW 55℉, LW 65℉
