Notes:
1.
You must know water flow direction to determine if cabinet requires
transition up or down.
2.
Transitions can only change by one diameter (1" to 1¼", 1¼" to 1½", etc.)
3. Riser transition couplings and run outs are factory brazed.
4.
All risers are factory pressure tested.
5.
Standard riser diameters are nominal 1”, 1¼”, 1½”, 2”, 2½”, and 3”. Please consult the
factory on pricing for nominal 4” water tubing.
6.
Copper Type M and L available (4" L only).
7. Drain riser insulated standard. Insulation is optional for supply and return
8. Leader riser - For follower cabinet riser ball valve assemblies, 12” of straight copper are
provided for field connection to the leader riser. Assembly to be cut to length and field
brazed. In applications where more than 12” of straight copper is needed, copper and
fittings to be field provided.
9. Standard ball valves have NPSH threads for connection to AHU hoses 1/2” for sizes 09-
12, 3/4” for 15-18, and 1” for sizes 24-36.
10. If cabinet stand or thick ISO pad is used, at installation add height/thickness to shutoff
valve and drain run out height. Verify riser shutoff height with plans before brazing.
Note: ClimateMaster units
with motorized valve option
have water high pressure
switches. Do not design riser
stack where switch will not
reset (trip - 300 PSI; Reset -
250 PSI).
