measured using the TDS meter supplied
- Replace the 5 micron sediment filter.
- Replace the carbon block filter.
- Replace the DI resin cartridge.
STORAGE
The following proceedures should be followed to protect
the unit from bacteria fouling and damage from freezing.
See "preliminary operations" in this manual for prefilters and
membrane removal and reinstallation instructions.
Short term storage: 2-4 weeks of non use.
1. Remove both prefilter housings and dump out the water.
2. Remove the DI resin cartridge housing and dump out the
water.
3. Remove top cap from RO membrane pressure vessel.
4. Open flush valve.
5. Lay unit down and allow all water to drain out for several
minutes.
6. Reinstall top cap on pressure vessel. Do not allow membrane
to dry out.
7. Reinstall prefilters and DI resin cartridge. Do not allow DI
resin cartridge to dry out.
Long term storage (winter storage): More than 4 weeks of
non use.
1. Remove both prefilter housings and dump out the water.
Reinstall with filters.
2. Remove the DI resin cartridge housing and dump out the
water. Reinstall housing without DI cartridge.
3. Wrap cartridge in plastic wrap and double seal it in a plastic
bags.
4. Remove top cap from RO membrane pressure vessel.
5. Remove RO membrane. Use a pliars and grip one of the
black spokes on the top of the membrane and lift. Do not grab
the small white tube.
6. Wrap membrane in plastic wrap and double seal it in a
plastic bag.
7. Reinstall cap on pressure vessel.
8. IMPORTANT NOTE: Protect from freezing. Store indoors
during winter season or whenever freezing temperatures
are possible.
9. Do not allow RO membrane of DI resin cartridge to dry out
or freeze. Damage will occur.
SYSTEM PERFORMANCE EVALUATION
In order to properly evaluate and troubleshoot the system, you
will need to perform a complete set of tests on the unit. These
tests will help identify the cause of the problem. To run these
tests, you will need the following items:
- Watch or clock with a sweep second hand.
- 3 gallon (12l) bucket.
- Volume measurement system. This could be volume gradua-
tion marks inside the bucket or a measuring cup/container.
Flow testing procedure:
- With water running from hose being tested, direct flow into
bucket for exactly 1 minute while timing with watch.
- Measure volume of water and record the gallons per minute
flow rate.
English
- If water volume is very low, perform a 2 - minute test and
divide flow by 2.
- If water volume is more than your bucket can hold in 1 minute,
take a 30 second flow test and multiply the result by 2.
- Record the results in gpm (gallons per minute) lpm (litres
per minute).
Use this procedure for all of the required flow tests as listed in
the following "System testing section".
1- Set up unit to run as per operation/owners manual.
2- Before connecting the supply water hose to the machine,
measure the water flow from the end of the hose(s).
Supply water flow _______________________________lpm
Supply water flow ______________________________ gpm
3. Measure the TDS and temperature of the supply water.
Supply water TDS ______________________________ppm
Supply water temperature _________________________ °C
4. Connect the supply water hose to the machine and turn
on the water. Open the flush valve to purge the air from the
system. Then close the flush valve and read the pressure on
the gauge.
Supply water pressure ___________________________ bar
5. Open the flush valve. Start the motor on the machine. Mea-
sure the water flow from the flush valve.
Flush water flow________________________________ lpm
Flush water flow________________________________gpm
6. Open the pure water valve. Allow water to flow onto the ground
or into a drain. For testing purposes, do not connect a pole hose.
Close flush valve. Wait for 1 minute to allow system to stabilize.
Read the system operating pressure on gauge.
System operating pressure ________________________ bar
7. Measure the water flow from the wastewater hose.
Wastewater flow ________________________________ lpm
Wastewater flow _______________________________ gpm
8. Measure the water flow from the pure water hose.
Pure water flow ________________________________ lpm
Pure water flow ________________________________ gpm
9. Measure the TDS of the pure water.
Pure water TDS _______________________________ ppm
10. Measure the TDS of the wastewater.
Wastewater TDS _______________________________ ppm
11. Turn off machine and compare test results to normal ope-
ration specifications on System analysis.
Note: Perform the operations in this order.
SYSTEM ANALYSIS
The following information of flows and pressures are median
values for the system. All system parameters will vary due to
water supply temperature and TDS level. System setup may
also affect the readings. i.e. extension cord size and length,
hose lengths and diameters. It is imperative to connect the
machine directly to the water and power source when evaluating
performance.
