Nominal capacity is outside of AHRI Standard 1230 and based on the following conditions:
• Cooling – Indoor 80°F DB / 66°F WB
Water Temperature Entering: 86°F
• Heating – Indoor 68°F DB
Water Temperature Entering: 68°F
2
When entering water temperature is lower than 59ºF, variable water flow control kit PWFCKN000
is required.
3
Sound pressure levels are tested in an anechoic chamber under ISO 3745 standard.
4
Value is calculated as follows: Δt = Total Heat of Rejection/(Nominal Flow Rate x 500).
5
Refer to the Refrigerant Piping section of this manual for correct line sizing. Contractor must use LG
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.
