RISER & CABINET INSTALLATION
Risers can be ordered loose, not attached to the cabinet, and shipped in bulk. Entire riser stacks can be assembled, pressure
tested, flushed, and filled before setting cabinets. Insulate all drain risers and insulate all tubing for extended range applications
(operation below 60 degrees F) or if condensation will occur on riser tubes. Do not construct walls until cabinets are installed
and set.
Supply and return risers can be straight, transition up, transition down, bottom capped, or top capped. Drain risers can be
straight, transition up, or top capped. All drain risers and extended range (operation below 50 ºF entering water temperature)
supply and return risers need insulation. See FIGURE 12 –Riser Identification

If filled risers are in unconditioned space, care must be
taken to prevent freezing or condensation to avoid
damage to risers and building.
