Core Drilling For Vertical Riser Stack
Core drilling slab slot/holes will determine cabinet place-
ment and surrounding walls. Slot/holes size, location
on floor and plumb alignment in two planes from top to
bottom are all very important, check plans. Size of slot/hole
will depend on slab thickness, ceiling height, riser length,
and if risers are attached to cabinet-which side risers are on
and how cabinet is angled into final position. Please see the
TSM and TSL submittals for reference.
Risers -
Risers can be ordered loose, not attached to the
cabinet and shipped in bulk separately. Crates will have
layers of risers by floors, each cabinets 3 risers (S,R,D) will
be next to each other. Lowest floor will be on top layer.
Risers will have a tag with the floor and riser number
(if the project information is filled out on the Solution
Center vertical stack selection screen). Entire riser stacks
can be assembled, pressure tested, flushed, and filled
before setting cabinets. Use caution if filled risers are in
unconditioned space, prevent freezing. Do not construct
walls until cabinets are set.
Risers may be different for every location and floor, check
before installing. All couplings and reducers are to be field
supplied.
Before brazing check building plans to be sure you are
installing correct riser; Description of riser, diameter, type,
and shutoff size are all variations. See figure 2 for help in
identifying riser and dimension to set riser run out. Note
dimension is from bottom of cabinet, add if stand or thick
isolation pads are used to get correct dimension from floor.
If local codes allow, PVC drain risers may be used.
Description -
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

CAUTION!
To ensure correct riser positioning and to
compensate for variations in floor-to-floor dimensions, do not
allow the unit to unit riser joint to bottom out.

WARNING!
To avoid damage from clogged coil surfaces,
clogged motor ventilation openings, seized fan blades and
potential unit failure, DO NOT OPERATE UNIT without
complete enclosure, supply grille, return air panel and filter in
place.

WARNING!
To prevent electrical shorts and drain pan leaks,
assure that screws do not penetrate unit components when
driving screws near the unit control box or drain pan. Do not
allow screws or nails to penetrate chassis, risers, electrical
junction boxes, raceways or to interfere with chassis removal.
To avoid motor or compressor damage, keep drywall dust out
of the unit.
