Note: Drain tube should be routed through metal
bracket and end of tube should be retained by metal
insert to create a trap. This trap should be lled with
water to prevent air from moving through the tube
and into the cabinet. Sometimes, gurgling sounds
will be heard upon the door closing as the internal
cabinet pressure changes requiring air to be pushed
out which happens through the drain tube trap.
