Plug the integrity tester into a power supply. Press the
scroll keys until the screen displays "Integrity Test". Press
ENTER and use the scroll keys to choose "Horizontal".
4
Open the outlet mini ball valve and press the ENTER key
on the integrity tester to begin the test. The integrity tester will
automatically proceed through all test steps.
5
The integrity test will take approximately 11 minutes to
complete for a horizontally-mounted system. At the end of the
test, one LED indicator will light.
The possible test results are:
• green leD - PASS
• Yellow LED - FAULT
• Red LED - FAIL
If a pass is indicated then the system integrity is good and it is
possible to proceed to the next step.
Integrity Test Fault
If a FAULT or FAIL is indicated, perform the integrity test again.
To repeat, CLOSE all mini ball valves. Open the inlet and outlet
valves and run a tap for 5 minutes. Begin again from Step 1.
Repeat the integrity test at least three times before assuming
that there is a fault within the system.
NOTE: If there is a FAIL, the most common cause is a leak
in the system from hoses, connections or a valve. Be sure
that all connections are tight before beginning the test and
the inlet and outlet valves are closed. Leaky valves and loose
connections will cause a FAIL.
If a FAULT yellow LED occurs during a test, a fault description
will appear. The following are potential notifications with
corresponding corrective actions:

Error Displayed
System pressure high, release

Open bottom JG valve
Pressure failed to rise
Failed to reach test pressure
Leak detected
Failed to stabilize
NOTE: If there is no water coming out from any tap after the
integrity test, check to ensure that both the inlet and outlet
valves have been reopened. Leave the tap running for a few
minutes to allow water flow to return to normal.
Following a FAULT yellow LED notification, take the appropriate
corrective action and re-do the integrity test.
6
Ensure that the inlet valve is still in the closed position.
Once a PASS green LED is achieved, close all mini ball valves
and remove both 1/4" tubings from the mini ball valves. Open
the outlet valve and turn on a tap downstream of the system
to relieve the air pressure inside the system. Turn off the tap
once water stops coming out.
Applicable to Horizontally-Mounted Systems Only:
Remove the spare mini ball valve and reinstall the air relief
valve (Figure 68). Attach a 1/4" tubing to inlet mini ball valve.
Direct the other end of the 1/4" tubing to a drain or large pail.
Open the inlet mini ball valve and drain out the water in the
internal prefilter cavity.
To Release Pressure:
This procedure is to be used if the following message is
encountered when commissioning the system: "System
Pressure High, Release Pressure"
This step is to be completed after the system is depressurized
and before the integrity test is done a second time, between
steps 1 and 2 in the integrity test step.
A. Close the outlet JG valve.
B. Disconnect the hose from the integrity tester.
C. Point the hose towards a drain or empty bucket and open
the outlet JG valve.
D. Keep the valve open until all the air has left the unit, a
steady slow stream of water should be flowing out of the
hose.
e. Close the JG valve.
f. Re-attach the hose to the integrity tester and restart the
integrity test.
Corrective Action
System pressure is too high.
Refer to Step 6 to release
pressure.
Outlet mini ball valve is closed.
Open valve and restart test.
Leaks in test set-up. Check for
leaks.
Test pressure was never
reached. Check for leaks.
Test pressure was never
reached. Check for leaks.
