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.
