Remarks
*1. Nominal cooling conditions:
Indoor: 80°F D.B. /67 °F W.B. (26.7°C D.B./19.4°C W.B.)
Outdoor: 95°F D.B. (35.0°C D.B.)

Indoor: 70°F D.B. (21.1°C D.B.)
Outdoor: 47°F D.B./43°F W.B. (8.3°C D.B./6.1°C W.B.)
*3. It cannot be connected to mixed CITY MULTI indoor unit and branch box indoor unit.
*4. Liquid pipe diameter: 12.7mm, when further piping length is longer than 90m, and when PEFY-P72 or P96 is connected.
*5. It is possible to set the external static pressure to 30 Pa by Dip Switch.
*6. 5 to 115°F D.B. (-15 to 46°C D.B.), when an optional Air Outlet Guide is installed. However, this condition does not apply to the indoor units listed in *7.
*7. 50 to 115°F (10 to 46°C) D.B.: When connecting PKFY-P06NBMU, PKFY-P08NHMU, PKFY-P04/06/08/12NLMU, PFFY-P06/08/12NEMU, and
PFFY-P06/08/12NRMU type indoor unit.
*8. When the temperature is below 50°F D.B. (10 °C D.B.) with branch box system, noise could potentially occur.
Notes:
• Nominal conditions *1, *2 are subject to AHRI 1230.
•
• See the following for unit conversion: kcal/h = kW × 860, Btu/h = kW × 3,412, cfm = m³/min × 35.31, lb = kg × 0.4536
•
• Details on foundation work, duct work, insulation work, electrical wiring, power source switch, and other items shall be referred to the Installation
