appropriate drain. Drain must be suitable for 0.35
GPM at 180° F. Kit contains ball valve, pressure
reducer, electronic ball valve, and fl ow reducer.
Installer must supply piping to tie into main water
line, and deliver water to appropriate drain.
Installations without uninterrupted supply of water •
during power outage (most houses with well pumps)
air cooled heat rejection system is available.
Contains vertically arranged side discharge fan-coil
unit installed outside, and is connected to HI Module
through closed coolant loop. Dimensions of unit are
24" Length, 15" Width, and 36" Height.
Air cooled heat rejection system installer must •
