Before any deviation from specified installation 
procedures is attempted, the customer or installer 
should contact the distributor.
IMPORTANT: Increasing the drain hose length, 
installing elbows, or causing bends will decrease 
drain flow rates and increase drain times, 
impairing machine performance.
Refer to Table 5 for capacity-specific drain 
information.
NOTE: Installation of additional machines will 
require larger drain connections. Refer to Table 6.
