RECOMMENDED MAINTENANCE
CAUTION: ANY REPLACEMENT FILTERS OR MEMBRANES NOT RECOMMENDED BY THE FACTORY
CAN CAUSE SEVERE DAMAGE TO THE SYSTEM AND VOID ALL WARRANTIES.
Before starting maintenance, check the reverse osmosis system for TDS reduction to determine if mem-
branes will or will not need to be changed.
If TDS reduction is less than 90% concentration, then the membrane should be replaced.
1) Shut off the water supply to the system.
2) Close storage tank ball valve.
3) Open the dispensing faucet to depressurize the system. (Allow 2 to 3 minutes).
4) Remove the filter housings by turning counter-clockwise.
5) Remove old filters and clean housings with a mild soap and water solution.
6) Check o-rings for deterioration and lubricate with an approved FDA silicone lubricant for o-rings or
replace
if needed.
7) Insert the appropriate new filters inside housings and replace them by mounting them in to position.
Make hand tight plus 1/8 to ¼ turn with housing wrench. DO NOT OVER-TIGHTEN. Over-tightening will
cause cracks and leaks if not careful.
CAUTION: ALWAYS MAKE SURE THAT O-RINGS ARE SEATED PROPERLY INSIDE SUMPS BEFORE
TIGHTENING CANISTERS.
8) If a membrane needs changing, remove the inlet tubing to the housing, unscrew the cap, and pull the
membrane out using a needle nosed pliers. Clean the inside of the membrane housing with a mild soap
and
water solution.
9) Lubricate the o-rings on the membrane permeate tube with an approved FDA silicone lubricant. Insert
into the housing with brine seal towards the opening. Make sure membrane is fully inserted and seated
into place.
10) Reseal the membrane housing with the cap and reconnect tubing.
11) To replace the carbon in-line post filter, remove the tubing and fittings at either end. Clean the old
Teflon tape off the threads and apply new tape. Screw the fittings into the new cartridge paying close
attention to the flow direction. Reinsert tubing.
