LG Therma V AHNW16809A2 - Indoor Unit Water System Setup

Installation of Indoor Unit
34 Air-to-Water Heat Pump
Water volume and pump capacity
The water pump is three speed-adjustable (Maximum / Medium / Minimum), so it may be required to
change default water pump speed in case of noise by water flow. In most case, however, it is
strongly recommended to set speed as Maximum.
Water pump speed
To secure enough water flow rate, do not set water pump speed as "Min."
It can lead unexpected flow rate error CH14.
