With the Internal Prefilter still removed, pour 2 cups
(500 ml) of 5 - 6% unscented household chlorine bleach
OR 1 cup (250 ml) of 12% chlorine bleach into the Prefilter
cavity. Replace the System Cap. Slowly open the Inlet

Test Description:
This automated test will pressurize the
membranes with air from the Outlet side of the System,
forcing clean water back through the membranes. Water
easily passes through the membranes due to the surface
tension of water, however air has a different surface ten
-
sion and does not normally pass through an intact mem-
brane. Once adequate air pressure has been achieved,
a pressure sensor measures any decay of that pressure.
The Integrity Tester analyzes the pressure data over this
interval. If the decay is within acceptable limits the Integrity
Tester will indicate a ‘PASS’.
Tools Required
Integrity Tester
Cap Wrench
2 - ¼” tubing
2 - Pressure Gauges
2 cups (500mL) of unscented household chlorine bleach
OR 1 packet of MC1 cleaning agent and a 1 cup (250 mL)
container
Other than the sanitizers, all required tools are included in
the Service Kit.
Note: A bucket may be required to collect some water if the
¼” tubing is not long enough to reach a drain.

Using the Controller, activate the Manual Flush
sequence. Refer to the instructions in the
Controller func-
tions
section under
E. inSTallaTiOn inSTrUCTiOnS
on how to perform a Manual Flush sequence. Once the
flushing is complete, open the Outlet Valve and a nearby
COLD water tap to flush most of the chlorine from the
System. Run the tap fully open for at least 10 minutes.
further flushing must be performed by the homeowner
later
. Refer to the
final flush by Homeowner
section at
the end of
f. COMMiSSiOninG
.
Note: Use only COLD water taps and continue the flow of
water until there is no chlorine smell.
Disinfection Procedure for Tools
All Pressure Gauges and tubing MUST be disinfected
prior to use to avoid cross-contamination and introduction
of contaminated water into the household System.
Place and soak the adaptor tip and the ¼” tubing ends in 5-
6% unscented household chlorine bleach for 5 minutes. The
brass adaptor will tarnish with time but this is acceptable. Do
not submerge the entire Pressure Gauge into the sanitizer
as it may damage it’s internal components. See FIGURE 40.
Do not use a bottle of bleach more than 3 months old.
If a Bypass Valve is installed, the Bypass Valve
should be closed for the entire procedure to
avoid contaminated water entering the household
distribution system. Contaminated water might
cause personal injury and in some cases death.
This cleaning procedure does NOT disinfect the
household pipes. If potentially microbiological-
ly unsafe water was present in the pipes, it is
strongly recommended that all pipes be sanitized.
WARNING!
Horizontally-mounted Systems:
With the Internal Prefilter still removed, unscrew the

integrity Test
Purpose:
This test ensures that the membranes are intact
and free from tears or ruptures that would permit bacte-
ria and other particles to pass through the membranes,
contaminating the filtered water. The Integrity Test is con
-
ducted at initial commissioning after the 15-minute flush
and subsequent sanitization and on an annual basis by a
Homespring™ Qualified Technician.
