Operating Procedures for ROPRO®Storage Tanks

Flowmatic Systems, Inc.

Dunnellon, Florida 1/1/02

ROPRO storage tanks are made from high quality food grade polypropylene, so
they will never dent, chip or rust. They are designed to provide superior service
throughout the life of your residential reverse osmosis system. Please follow the
procedures described below:

Placement

Storage tanks may be placed vertically or on their side where it is convenient, within ten feet
of the faucet. Under sink or in a nearby cabinet are excellent choices. If tank is
located further than ten feet from the faucet, use 1/2” or 3/8” tubing to reduce
pressure drop. When full, tank may weigh more than thirty pounds, so a sturdy shelf is
required.

Temperature

ROPRO tanks should not be used at temperatures below 40°F or above 125°F.

Pre-fill tanks for best results

Pre-filling the storage tank is always recommended so there is sufficient pressure
to check for leaks and make certain you have sufficient water to flush the carbon
post filter. To pre-fill tanks, connect storage tank to feed water line. Open feed
water valve in tank. Allow tank to fill for approximately three minutes. Turn off
feed water valve and tank valve to check for leaks. Empty tank after initial use to
flush system.

Sanitizing instructions

It may be necessary to sanitize RO systems and ROPRO tanks from time to time. To
successfully complete this procedure, close the feed water valve and follow the sanitizing
instructions provided by your RO system manufacturer.

A 5% Clorox

®

bleach is an acceptable sanitizing solution, along with similar
brands. To sanitize tank, flush system with chlorine and allow the water and
chlorine solution to flow into tank. Discard the first two tanks of water produced
as they contain chlorine. Do not use this water.

Do not directly expose tank to high concentrations of sanitizing chemicals.
Properly dilute bleach with water to prevent damage to tank and diaphragm.

Air loss

Tanks are pre charged with air, to 7 psi. If flow is reduced, check air pressure and add
air if necessary.
