Pre-installation Notes
▪ This installation guide provides a step-by-step, start to finish procedure for installing your iSpring
whole house water filter. All steps provided herein are for typical installations only. Your specific
application may vary.
▪ This filter system should not be used with water that is microbiologically unsafe or of unknown
quality without adequate disinfection before and/or after the system.
▪ The filter should be kept in a sheltered location and should never be exposed to freezing or
extreme temperatures and direct sunlight. Such damage is not covered under any warranty.
▪ Be sure to note the inlet / outlet markings and the water flow direction.
▪ A three-valve bypass valve and loop may be installed to loop the entire system to make servicing
easier.
▪ Hard copper pipes generally come in two types. Use the thicker "L" type copper pipe rather than
thinner "M" type copper pipe.
▪ Follow all local plumbing and building codes.
