Annual Maintenance - GE Homespring Operation Manual

G. ANNUAL MAINTENANCE
To extend the life of the system's membrane, maintenance
procedures are recommended on a minimum of an annual
basis. A service kit is required, including an integrity tester and
other necessary tools to perform the annual maintenance.
A Homespring qualified technician must perform all
maintenance including the annual integrity test as required
as part of the 5 year limited prorated system warranty. If the
Homespring qualified technician determines that the system
has a high degree of debris causing a reduction in the flow
rate, the number of maintenance visits per year may be
increased to ensure that the system stays within operational
limits, and to ensure the limited prorated warranty protection
remains in effect.
Annual Maintenance Procedure
1
Transmembrane Pressure (TMP) Test
The first step will be to perform a "pre-cleaning" TMP test.
To perform this test, follow the steps in the Transmembrane
Pressure Test section. This test will be performed prior to
cleaning and again following the integrity test. The results of
these tests are to be recorded on the service tag.
If the inlet valve is upstream of the external prefilter, change
the external prefilter following guidelines in the Surface Water
Option Kit Installation section before beginning the membrane
cleaning.

Backpulse Tank Pressure Check
Using the digital air pressure gauge, check the backpulse tank
pressure. If it is not at the correct pressure (approximately 35
psi for most installations; refer to the service tag for the actual
reading), adjust the pressure using an air pump or compressor.
Refer to step 4 of the System Installation section for guidance.

Membrane Cleaning
WARNING:
gloves must be worn during maintenance of the system
to protect your hands. At the end of the procedure,
wash your hands thoroughly with soap and water.
Do not reuse the gloves. Dispose of the gloves in the
garbage.
For installations excluding ground water installations, clean
the membrane following the steps in the Cleaning section
with the following exceptions. In step 3, after the system cap
is removed, wipe the system cap out with a clean, soft cloth,
remove the O-ring carefully. Wipe the O-ring with a clean
cloth, check the O-ring for damage or wear. Apply a very small
amount of DOW CORNING 111 silicone lubricant on the O-ring,
and replace the O-ring. If necessary, replace the O-ring with a
new O-ring. And in Step 4, let the system stand for 60 minutes
instead of 15 minutes.

Disposable protective
For ground water installations, clean the membrane following
the steps in the Cleaning section with the exception of
replacing step 4 with the following:
If needed pour the contents of the MC1 cleaning agent into
a container with 250 ml (1 cup) of water. Mix thoroughly to
dissolve the crystals.
For vertical systems, with the internal prefilter still removed,
pour the solution into the prefilter cavity and stir. Inspect and
clean the thimble filter as needed.
For horizontally-mounted systems, remove the 1/2" brass plug
of the air vent assembly and pour the solution into the casing
cavity through the 1/2" NPT port. Refer to Figure 65 for the
location of the 1/2" brass plug.
WARNING:
cleaning agent coming in contact with skin or clothing.
Wash the mixing container well before reuse.
WARNING:
combined with any other chemical or cleaning solution,
especially hypochlorite or household chlorine bleach.
Failure to do can result in serious personal injury,
illness, or death.
Replace the system cap (vertical systems) or the 1/2" brass
plug (horizontally-mounted systems). Let stand for 60 minutes.

Integrity Test and Prefilter Replacement
The integrity test is to be performed as described in the
Integrity Test section, including the installation of a new
carbon prefilter if a carbon prefilter is in use.
If the system is utilizing a stainless steel prefilter, the stainless
steel prefilter must be checked for damage, washed with soap
and water (when water is available), rinsed and reinstalled
following the integrity test. Only if it is damaged should the
stainless steel prefilter be replaced with a new one.
If the system includes an external prefilter (a model with the
surface water option kit) and is installed downstream of the
inlet valve, the external prefilter should be replaced during the
cleaning. Follow guidelines in the Surface Water Option Kit
Installation section to install a new external prefilter cartridge.
