Nominal capacity is outside of AHRI Standard 1230 and based on the following conditions:
1
• Cooling – Indoor 80°F DB / 66°F WB
Water Temperature Entering: 86°F
• Heating – Indoor 68°F DB
Water Temperature Entering: 68°F
When entering water temperature is lower than 59ºF, variable water flow control kit PWFCKN000

manufactured Y-Branch and Header Kits only. Designer must verify refrigerant piping design configura-
tion using LG's computerized refrigerant piping software (LATS Multi V) to validate the pipe design.
