Hydrotech Aqua Flo Ultra 2 Under Sink Filter System - Manual (Page 3)

Instruction #1 - Cleaning, Sanitizing and Cartridge Replacement Procedure
1. Mix mild cleaning solution of dish
soap and clean potable water in
plastic bowl.
2. Relieve presure by closing feed water
supply valve and open product water
faucet.
Icemaker: Transfer ice cubes from
bin/tray to clean freezer container for
storage until procedure is done.
3. CAUTION: Do not attempt to remove
filter housings until water flow stops.
This reduces pressure inside
the system so housings may safely
be removed.
CAUTION: Additional point-of-use
devices (i.e., icemakers) may use
filters along their supply line. Remove
any filter or treatment device installed
between module and device before
proceeding.
Remove each filter/membrane
housing by turning it counter-
clockwise. Remove each filter
cartridge as its housing is removed.
Discard filters.
4. CAUTION: Use sanitary rubber
gloves for this procedure to avoid
contaminating sanitizing solution,
filters, or membrane. Wear gloves
whenever cleaning/ sanitizing system
components or handling new
filter/membrane cartridges.
5. Remove filter housing "O" rings and
wash them with cleaning solution.
Rinse them well with clean potable
water. Inspect them for damage (i.e.,
nicks, scratches). Replace damaged
"O" rings.
6. Clean filter housings ports, inside and
outside, with washcloth and cleaning
solution. Do not use abrasive
materials.
7. Rinse manifold/housings with clean
potable water.
8. Inspect manifold and filter housing
"O" ring groove area for damage (i.e.,
nicks or scratches). Replace
damaged components.
9. Place a small amount of "O" ring
lubricant over surface of filter housing
"O" ring. Install "O" ring into filter
housing groove.
TO SANITIZE THE SYSTEM: Complete
Steps 12-20.

Mix sanitizing solution of 1.5 ml (1/3
teaspoon) of household bleach and
3.8 L (1 gallon) of clean, potable
water in the bucket. Mix solution well.

will over-tighten and damage
housings. Take care not to cut or
pinch o-rings.
Add 236 ml (one cup or 8 oz.) of
sanitizing solution to each filter
housing and install them onto the
manifold (do not install filters or
membrane at this time). Tighten each
filter housing by hand only.

water supply valve.
15. Wait 25 minutes, then open product
water faucet and let water flow to

of water. Rinse filter housings and
manifold ports thoroughly with clean
potable water.
17. CAUTION: Do not remove protective
plastic bag from replacement filter
cartridges until so instructed.

expose filter cap and "O" ring
grooves. Place a small amount of "O"
ring lubricant on surface of each "O"
ring.
18. CAUTION: TIGHTEN FILTER
HOUSINGS BY HAND ONLY. Do not
use tools as they will over-tighten and
damage housings. Take care not to
cut or pinch o-rings.
CAUTION: Refer to Installation
Instructions for the location of each
cartridge.
