Riser and Cabinet Installation, Cont’d.
Type M has red identification marking (stripe running down
the tube) and Type L (thicker wall) has blue identification
marking. If tube is insulated pull back carefully to check
color.
Shutoff ball valves and hose sizes for cabinet/chassis
-
1/2” for sizes 09-12, 3/4” for 15-18, and 1” for sizes
24-36.
Supply riser is always closest to back corner of cabinet,
return riser next, and drain riser in approx. middle of the
cabinet. Supply risers are 9.25” (235) apart from drain on
centerline. See Figures 2 & 3.
Secure Riser Stack to building structure so stack does
not drop over time. Cabinet slots allow for 1.50” (38mm)
maximum expansion and 1.50” (38mm) maximum contrac
-
tion, use expansion devices if you exceed these values, and
between clamps.
NOTICE: Any risers misplaced, assembled in wrong
location, brazed incorrect, modified incorrect (including
cutting off or extending), runoff at incorrect height,
misalignment found anytime including when cabinets
are set, not using expansion devices if specified, or stack
was not supported correctly is the sole responsibility of
the installing contractor.
Riser Installation When Risers are Shipped Separately
1. Check riser diameter, type, valve size, and position
(S,R,D or D,S,R) of risers per cabinet configuration (see
floor plans).
2. Suggest each cabinet location be marked with all
information (see figure 5 ).
3. Starting on lowest floor center risers in slot. Set height
of supply and return run-outs to 39.75” (1100) and
drain run-out to 3.12” (79) from bottom of cabinet.
Temporally secure risers (not by rubout or valve) so
they do not move.
4. If riser extensions are used insert them on lower floor
top of riser, mark like step 5.
5. Next floor up mark riser at bottom at 1” (25) and 2.50”
(63), drop through slot and position run-outs same as
step 2. Temporally support.
6. On lower floor check that above riser is inserted
between 1” (25) and 2.50” (63) (between 2 marks you
made). Cut riser if needed or use extension.
7. Insert expansion devices if required by plans.
8. Continue until complete riser stack is assembled.
9. Check all risers are correct diameter, type, valve size;
correctly positioned; centered in slot; plumb from top to
bottom; depth into swedge correct; run-outs at correct
height, and shutoff valve handles are parallel with the
side of cabinet. (see Figure 2)
10. Braze all joints with high temperature alloy like
Phoscopper or Silfos. (DO NOT use soft solder 50-
50, 60-40 or 85-15; low temperature alloys are not
acceptable for this application).
11. Must securely anchor riser stacks to building structure
at least on one floor. Typically at middle floor and
additional floors as needed. Example: 40 floors, anchor
at 10, 20, and 30. Use expansion devices between
anchors.
12. Remove temporary supports.
13. Check that risers did not drop. If stack dropped, jack up
and add additional anchor support.
14. Verify all shutoff valves are closed. DO NOT OPEN
VALVES until system has been cleaned and flushed.
15. Pressure check risers–locate and repair any leaks–
retest.
16. 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.
17. Install air vents in piping loop at highest accessible
point as required to bleed the system of air
accumulated during installation.
Cabinet Installation When Risers are Shipped Separate
or Field Provided
1. Check plans that cabinet is correct for location, cabinet
will have label and data plate with information,
including unit size, diameters of risers, and electrical
data.
2. Remove riser KO’s (3) for your cabinet configuration
(see Figure 2).
3. Cover supply and return openings with 4 pads. Slit
with knife (see Figure 7a).
4. Slide cabinet up to riser allow 1/4” to 1” (6 to 25 mm)
clearance.
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.
a. Anchor built-in risers to the building structure
with at least one contact point. To accommodate
vertical expansion and contraction DO NOT fasten
risers rigidly within the unit.
b. Verify that unit shut-off valves are closed. DO NOT
