Product Assembling and Installations
1). Before Installation
Ensure there is enough space at the desired location for the system and to change filters
safely. Contaminated water will run out of the drain line, so be sure to consider this.
Verify no parts are missing from the package. Contact iSpring if any part is missing or
defective.
Tools required for assembly:
Figure 5. Recommended Tools
2). Assembling the Machine Head
Remove the screws on the clamps located on both ends of the stainless-steel membrane
housing. Also, remove the caps on both ends.
Verify the O-rings on both caps (4 in total) are correctly in place.
Take the RO 1000G out of its package and place it in the stainless-steel membrane housing.
Pay careful attention to the direction of the arrow on the RO membrane; it must be the
same as the direction of the stainless-steel membrane housing.
Replace the caps on the stainless-steel membrane housing and screw the clamps in place.
Pay attention to the ends of the caps.
Insert the PE tube into the quick connector on the lower left side. You do not need to insert
the upper quick connector on the left side at this point. After the first three-stage filter is
flushed with water, install the quick connector on the upper side. Then rinse for 3-5
minutes before connecting the PE tube to the water inlet of the RO membrane. This serves
to prevent damage to the RO membrane from the activated carbon particles washed out
from the first rinse.

3). Assembling the System Body
The 4 Omni wheels are locked onto the frame base, and the foot brake can be pressed down
into the locked position for subsequent installation.
Insert three frame pillars into the three square slots of the frame base. Pay careful attention
to the opening direction of the frame pillars, as it is the same as the opening direction of the
frame base. Then screw on the M8 bolts and use a wrench to lock the bolts and fix the
frame pillars.
Place the machine head on the three fixed frame pillars, then determine the orientation and
lock the three M6 screws. Next, fix the machine head and confirm that the entire steel
frame is stable as assembled.
Take out 3 filters and remove their PE protective film. Install the 3 filters: the PP sediment
filter, and 2 CTO filter in order from right to left, and use the housing wrench to tighten the
housing.
Install the water outlet into the outlet of the RO membrane housing. Pay attention to the
interface between pure water and waste water. The water outlet tube is white and blue: the
blue tube runs pure water, and the white tube runs waste water:

www.123filter.com | [phone] | [email protected] Page 10
The pure water inlet is connected to the quick connector in the middle of the membrane
housing cap, and the outlet is connected to water-using equipment such as a pure water
faucet.
The wastewater inlet is connected to the quick connector on the outside of the membrane
housing cap, and the outlet discharges sewage through the sewage pipe.
Connect the system’s water inlet to the water supply pipe. The system comes with a 3/4"
NPT female connection. A 3/4" NPT to 3/4" quick-connect brass fitting connector is also
included. Different types of connections can be used based on the user’s actual setup.

Using the System
1). Initial Setup
It is essential to flush the system to avoid damage to the reverse osmosis membrane. Flushes
should be performed each time the filters are changed as well. Disconnect the PE tubing
between the 3rd stage and the membrane housing. Place the end of the tubing in a drain or
container, then turn on the water supply and flush the first 3 stage pre-filter for at least 5
minutes. Turn off the water after the flush is complete and connect the tubing to the reverse
osmosis membrane housing.
Figure 10. Flushing the System
After all the tubing is connected, turn on the water supply and make sure the system is not
leaking. Verify the ball valve on the automatic shutoff components is in the “on” position
(shown in Figure 10.). Then keep the water running and rinse the membrane for at least 30
minutes. This process serves to kick start the membrane by rinsing off the protective
solutions on the membrane’s surface. It is recommended that users manually rinse the
membrane for 5 minutes at least every 3-6 months to ensure the maximum performance of
the membrane.
Disconnect this tubing
for initial flush.

The system is now ready to use. Make sure the drain line is in position for proper
wastewater dispense.
2). Daily Maintenance and Filter Replacement Schedule
The first stage should be replaced every 3 – 6 months depending on source water quality.
This stage comes with a transparent housing that enables simple, periodic visual checks of
the filter. Replace the filter as soon as you see any buildup on the surface of the filter, or if
you see a significant change in the filter’s color.
The 2nd and 3rd Stage should be replaced every 6-12 months, depending on source water
quality. Replace the filters immediately anytime you observe a significant pressure drop.
The reverse osmosis membrane should be replaced every 2 – 3 years if it is regularly rinsed
(5 minutes every 3-6 months).
To replace the first 3 stages filter, turn off the inline water supply, drain the remaining water
in the system, use the included housing wrench, turn clock wise to unscrew the housing.
Dispose the old filters and instert the new ones. Place the housing back to attach to the
housing cap, make sure the orings are in place, apply luberication if required. Hand tight the
housing then use the housing wrench, turn counter-clock wise for another 1 to 1 ½ rounds.

Figure 12. How to Use the Housing Wrench
To replace the RO membrane, turn off the inline water supply, drain the remaining water in
the system. The membrane housing comes with 1 cap on each end, and membrane can be
replaced from either end thus only one cap is needed to be removed. Remove the tubing on
the quick fittings of the side to be taken off, loosen the M8 screw that locks the cap then
pull the membrane cap out. Pull out the old membrnae with a pair of pliers, insert new
membrane. Replace the cap, make sure the orings are in place and fasten the M8 screw.
Instert the tubing back to the quick connecting fittings.
Please be advised that the system needs to be running for at least 30 minutes after any filter
is changed before the water can be consumed.
3). Recommendations and Tips
All 4 Omni wheels come with a brake and leveling system. Simply press the brake down to
apply the brake and lift the brake to release and move the system with ease. The height of
the Omni wheels can be adjusted by a wrench to keep the system level.
Pressure gauges are connected to the outlet of the 1st and 3rd stages. If the difference
between the 2 gauges is greater than 5 psi, there are contaminates blocking the filters. The
first 3 filters should be replaced as soon as possible to ensure maximum performance.
If the inline water pressure is less than 70 psi, or the ambient temperature is below 60°F, use
the optional booster pump (Model number PMP1000) to ensure optimal performance.
