Riser and Cabinet Installation, Cont’d.
OPEN VALVES until the system has been cleaned
and flushed.
6. For cabinets with chassis inside - remove 4 shipping
screws, discard.
7. Remove inner panel (8 screws), save both.
8. Remove condensate pan shipping wire ties.
9. P-Trap Hose must be connected, lift drain pan, extend
drain riser stub into cabinet, measure and cut drain
hose to length, connect rubber p-trap to riser and
clamp. If condensate hose must be rotated, loosen
clamp on pan, rotate, and reclamp. Check condensate
drain - clean pan if needed. Slowly pour 1 to 2 quarts
(1 to 2 liters) of water into pan. Water should drain
freely. Check for water in cabinet and on floor. Repair if
needed, and then retest.
10. Sheet metal ductwork should not be attached to
the cabinet. A canvas-type flexible connection is
recommended between the cabinet and the ductwork.
Cabinet Installation When Risers are Attached
(See Figure 2)
1. Check plans that cabinet is correct for location, cabinet
will have a label and data plate with information,
including unit size, diameters of risers, and electrical
data (if the project information is filled out on the
Solution Center vertical stack selection screen). Move
cabinet close to slab slot, do not carry cabinet using
risers, always use 2 people.
2. Check risers are 3” above the top of cabinet. If not
loosen straps, adjust riser and re-tighten.
3.
For applicable cabinet options configure supply air
openings and attach angles. See Pre-Installation. If
optional stand is required attach to bottom of cabinet
with 4 screws.
4. Start on lowest floor, lift cabinet and angle so risers
pass through slab slot/holes until cabinet is standing
up and setting on floor. Be careful not to damage
either end of riser, do not carry cabinet using risers.
Move cabinet until risers are centered in slot/holes
and cabinet sides are square with proposed walls.
If extensions are used, assemble to risers on lower
floor. Mark set depth in case they drop before brazing.
Dimension should be 1” to 2”. Less than 1” or more
than 2-1/2” is not acceptable. Extensions should never
bottom in swedge of riser.
Note: Riser joints should
be well below slab for brazing/inspection.
5.
Attach the cabinet assembly to the floor on at least two
sides using sheet metal angles. Additional anchorage
may be provided by installing brackets at the top of the
cabinet.
6. DO NOT attach drywall studs to cabinet. When all
units on a riser are anchored into place, complete riser
joints as follows:
a.
Verify that all riser joints are vertically aligned and
that risers penetrate 1” to 2” (25 to 50) into the
swaged joint of the riser below. DO NOT let riser
joint bottom out. Check run outs enter cabinet at 90°.
b. Braze riser joints with a high-temperature alloy
(such as Phos-copper or Silfos). Soft solder (50-
50, 60-40 or 85-15) or low-temperature alloys are
NOT suitable for this application.
c. Must securely anchor riser stacks to the building
structure with at least one contact point. Typically
at middle floors as needed. Example, a 40 floor
building would be anchored at floors 10, 20,
and 30. To accommodate vertical expansion
and contraction use expansion devices between
anchors. DO NOT fasten risers rigidly within the
unit.
d. Verify that unit shut-off valves are closed. DO NOT
OPEN VALVES until the system has been cleaned
and flushed.
e. Pressure check riser - locate and repair leaks.
f. If condensate hose must be rotated, loosen clamp
on pan, rotate, and re-clamp. Check condensate
drain - clean pan if needed. Slowly pour 1 to 2
quarts (1 to 2 liters) of water into pan. Water
should drain freely. Check for water in cabinet and
on floor. Repair if needed.
g. Repair or replace any damaged or missing
insulation on risers, and extensions (if used).
h. To facilitate cleaning and flushing, install the hose
kit at the end farthest from the pump and connect
the ends of the hoses with the riser flush adapter
(Kit - AFL5751). Then open both valves before
pumping fresh water through the system, close the
valves when the system is clean. Remove the flush
adapter before installing the chassis.
Note: Refer to System Flushing Section of this
manual for more information.
i. Install air vents in piping loop at highest accessible
point as required to bleed the system of air
accumulated during installation.
7.
Next floor up select correct unit. Suggest measuring
from top of slab to top of riser below. Now measure
from bottom of cabinet (or stand/pad if used) to bottom
of riser, this dimension should be 1” to 2”more than
first measurement. Less than 1” or more than 2-1/2” is
not acceptable. Risers should never bottom in swedge
below. Cut riser or extension if needed. DO NOT slide
riser up or down on cabinet. Repeat steps 2-5.
