7-LXCTAIR, 7-LXIMAIR INSTALLATION INSTRUCTIONS
Add mineral per instructions in this filter manual. Water can be manually added at this time to begin the mineral soaking
process.
An in-line check valve is required, installed vertically prior to the aeration system, but after any untreated lines. Provide at
least a 12” vertical column of water pipe on top of the check valve before the aeration system. See diagram below.
A check valve and a small piece of tubing is installed on the “brine elbow”. This must be in place to prevent water from
discharging during the backwash sequence. See diagram below.

A SMALL AMOUNT OF AIR MAY BECOME TRAPPED IN THE SERVICE LINE AFTER THE AERATION SYSTEM BACKWASHES.
A SPUTTERING OF AIR MAY BE NOTICED AT THE FIRST WATER FIXTURE TO BE USED AFTER THE SYSTEM BACKWASHES.
IF THIS IS OBJECTIONABLE, A CHECK VALVE CAN BE INSTALLED DIRECTLY AFTER THE AERATION SYSTEM.
NOTE: IF A CHECK VALVE IS INSTALLED BETWEEN A PRESSURE TANK AND A WATER HEATER, A HOT WATER EXPANSION TANK
IS REQUIRED ON THE COLD WATER INLET OF THE WATER HEATER.

Follow installation instruction in this manual for plumbing the inlet and outlet.
Special precautions must be made when connecting the drain line. Hard piping is
recommended. During backwash, air and water escape quickly, causing a flexible drain line to
whip and thrash. Attach the drain line securely to an air gap device on the waste water line.
