Using the controller, activate the manual flush sequence.
Refer to the instructions in the Controller Functions section on
how to perform a manual flush sequence. Run manual flush
2-3 times then proceed to flush thru tap. 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.
NOTE: Use only COLD water taps and continue the flow of
water until there is no chlorine smell.
Integrity Test
Purpose
This test ensures that the membranes are intact and free
from tears or ruptures that would permit bacteria and other
particles to pass through the membranes, contaminating
the filtered water. The integrity test is conducted at initial
commissioning after the 15-minute flush and subsequent
sanitization and on an annual basis by a Homespring qualified
technician.
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 tension and does not normally pass
through an intact membrane. 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
• 2 lengths - 1/4" tubing
• 2 cups (500 ml) of unscented household chlorine
bleach (Clorox)
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
1/4" tubing is not long enough to reach a drain.
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.

• Cap wrench
• 2 - Pressure gauges
Place and soak the adaptor tip and the 1/4" tubing ends in
5-6% unscented household chlorine bleach (Clorox) 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 25.

Close inlet and outlet valves. Use the controller to
initiate a manual flush sequence to bring the system pressure
to zero. Refer to the instructions in the Controller Functions
section on how to perform a manual flush sequence. Insert
pressure gauges into the inlet and outlet mini ball valves and
open the valves. Confirm that the system pressure is zero.

Close the inlet mini ball valve (Figure 27), remove the
pressure gauge. Insert 1/4" tubing into the inlet mini ball
valve. Direct this tubing to a drain or a pail, and reopen the
inlet mini ball valve. Plug one end of the second 1/4" tubing
into the outlet mini ball valve and the other end into the
integrity tester.
