3.4 DRAIN CONNECTION
IMPORTANT: Machine must be installed in accordance with all local codes and ordinances.
All drain systems must be vented to prevent an air lock or siphoning.
If proper drain size is not available or practical, a surge tank is required. A surge tank along with a sump pump should be used
when gravity drainage is not possible.
