Original Instructions
Operating Precautions
• Pretreat feed water if indicated by the Labconco Water Profile test, to extend life of the RO
membrane.
• Change prefilters frequently as stated in this manual to prevent free chlorine from
destroying the RO membrane.
• Ensure that the unit is connected to electrical service according to local and national
electrical codes. Failure to do so may create a fire or electrical hazard.
• Do not remove or service any electrical components without first disconnecting the RO
system from the outlet.
• Preserve RO membrane whenever unit is unplugged for more than a week without usage
per instructions under “Preserving RO Membrane” page 23.
• System performance and cartridge life span are directly related to the feed water quality. It
is important to establish feed water quality before operating the unit.
Thoroughly understand procedures and equipment before beginning work. Prefilter,
carbon/prefilter and RO membrane should already be installed. See page 14 of this manual.
