M. FLUSH THE APPLIANCE OF THE PRESERVATIVE
AND CHECK THE OPERATION
1) With the tank valve closed (the tank should still contain the
sanitizing solution at this point), open the faucet (set the
faucet handle in the “up” position) and feed water valve.
Water should begin to drip from the faucet within several
minutes. Continue to flush the system for 24 hours. Water
will steadily drip from the faucet at this time. During this
procedure, the tank is being intentionally bypassed in
order to thoroughly sanitize the tank and also flush the
membrane of any preservatives.
To reduce the risk associated with irritation from Sodium Metabi-
sulfite during installation:
•
Sodium Metabisulfite (CAS 07681-57-4) is used in a
1% preservative solution within the reverse osmosis
membrane.
•
Do not put this system into service before the RO
tank is flushed as specified in the installation instruc-
tions. Wear eye and face protection during installa-
tion.
•
To request an MSDS relating to this product, call 203-
238-8965 or visit the web at http://solutions.3m.com/
wps/portal/3M/en_US/MSDS (click MSDS search). For
emergencies, call 800-364-3577 or 651-737-6501 (24
hours).
2) After flushing for 24 hours, shut off the faucet. Open the tank
valve, lift the faucet handle again and allow the tank to
completely empty. When the tank is empty, the faucet will
drip steadily. Measure and record the rate at which water
drips from the faucet. Use a graduated cylinder (in
milliliters) and a watch with a second hand to calculate the
approximate production in gallons per day (milliliters per
minute x 0.38 = gpd). Proceed to check the reject flow by
disconnecting the tubing at the drain connection and
measuring the drip rate as outlined above. The ratio
should be a minimum of 2.5 (reject) to 1 (product).
Repeat every 5 minutes until the rate is constant. When
the rate is constant, the tank is empty.
3) Allow the system to operate in this condition for 24 hours.
4) Close the faucet and reinspect the appliance for leaks.
Allow the tank to fill completely (it will take approximately
4 hours), then drain the tank again.
The water should be
discarded because it may contain some sanitizing solu-
tion.
5) The appliance should be ready to use as soon as the tank
refills. If any objectionable taste is noticed after the
second tankful is drained, instruct the customer to wait
and drain the tank the following day. Only at this time
should an icemaker be turned on if one is connected to
the appliance.
N. CLEAN UP AND PAPERWORK
1) Clean up the work area thoroughly.
2) Fill out the warranty card and return it.
For replacement parts and filters, please contact your dealer
or call Water Factory Systems at 1-800-733-1199 or visit our

This system has been tested for the treatment of water contain-
ing pentavalent arsenic (also known as As(V), As(+5), or arse-
nate) at concentrations of 0.30 mg/L or less. This system treats
pentavalent arsenic, but may not affect other forms of arsenic.
This system is to be used on water supplies containing a detect-
able free chlorine residual or on water supplies that have been
demonstrated to contain only pentavalent arsenic. Treatment
with chloramine (combined chlorine) is not sufficient to ensure
complete conversion of trivalent arsenic to pentavalent arsenic.
Please see the Arsenic Facts section of the Performance Data
Sheet for further information.
