OUTDOOR INSTALLATIONS — provide and install electric heat
tape
and insulation of the pipes on the condensate drain lines and
around the NBT-23 tank to prevent possibility of neutralizer tube
damage or line blockage due to freezing. Failure to comply with the
following guidelines could result in severe personal injury, death or
substantial property damage.
