SETUP STEPS

1. The unit should be level (left to right - front to back), on a secure surface.

2. Connect the water line to the water inlet tting on the rear of the unit. Water volume ow to the machine
should be consistent. Use tubing sized sufciently to provide a minimum ow rate of one gallon per minute.

NOTE: A water ltration system must be used to help maintain trouble-free operation. Air must
be purged from the cartridge prior to connection to equipment. In areas with extremely hard
water, we highly recommend the use of a Curtis approved water lter. For our full line of lters,
please log on to www.wilburcurtis.com.

NSF International requires the following water connection:

1. A quick disconnect or additional coiled tubing (at least 2x the depth of the unit) is required so

that the unit can be moved for cleaning.
