    6. PIPING DESIGN R2-Series For Sub-HBC controller For Sub-HBC controller, connect the drain pipe by following the steps described below. 1. Insert the drain hose (accessory) into the drain port (insertion margin: 32 mm). (The drain hose must not be bent more than 45° to prevent the hose from breaking or clogging.) (Attach the hose with glue, and fix it with the band (small, accessory).) 2.
