Installation and Maintenance

If there is any questions or concerns during the installation, please call iSpring’s technical support at 1-678-261-7611 Monday thru Friday, 9:00 am – 5:00 pm, EST.

3-1 Installation

This system is can be installed counter top on the existing faucet (parts are included) or under the sink with optional installation kit (not included). For information of the under-sink installation kit, please consult our customer service department or check out our website listing.

This part of instruction is drafted for installation on existing faucet only.
Install the 3- way feed water valve to the faucet. If the faucet is standard size, simply replace the existing aerator with the included standard 55/64’’ adapter by screwing off the aerator. A wrench might be needed.
If the faucet is not standard sized, please use the included all-purpose adapter instead. Gently apply 2-3 rounds of plumber’s tape on the adapter, then screw the feed water valve to the installed adapter, make sure the connection is tight by using the wrench to tighten it.
Insert the red tube to the adapter port labeled with” in”. Connect the blue tubing to the adapter port labeled with “out”. The white tubing from the other side of the system is the waste water drain line, and should be inserted to the included suction disk and then attach to the sink sidewall.
Note: the tubing should be pre-installed to the system. If the tubing came loose, please contact iSpring customer service for help.
Turn on the faucet. To use the tap water, turn the handle on the feed water valve to the “on” location as shown below:

To use get reverse osmosis water, turn the handle to the “Off” location, shown as below:

Check if there’s any leak inside the system or from the feed water valve. If there’s leak on the valve, make sure enough plumber’s tape has been applied and the adapter is tight enough. If there’s any internal leak, contact iSpring customer service immediately.

RO water will flow out from the smaller water outlet located on the valve. Rinse the whole system for at least 30 minutes before using the filtered water.
The installation is now completed. Please monitor the water quality by testing the water with a TDS meter and change filters based on our recommended schedule.

3-2 Replacing filters:

Turn off the water supply, drain all excessive water remained in the system.
Remove the case of the system by removing the 6 screws on the edge with a Philips screw driver.
The PAC filter and post carbon filter use ¼’’ inline quick fitting on both ends. To remove the old filters, use both hands, press the fitting ring with one hand, pull the tubing out with another, as shown below.
HOW TO DISCONNECT
To replace the reverse osmosis membrane, remove the tubing from the quick connect fitting on the membrane housing (refer to previous steps on how to remove quick connect fittings), use the housing wrench included in the package, twist off the housing cap in a counter-clockwise direction. Pull out the old membrane, due to water pressure in the housing, pliers may be needed. Clean and rinse the membrane housing with running water. Hold the new membrane, insert it into the housing with the end with black rubber seal facing out, as shown in the image below.

Place the membrane housing cap back, make sure the o-rings are in place on the housing, and hand tighten it. Use the housing wrench to tighten another ¼ – ½ of a turn.
Let the water running and flush the system for at least 30 minutes each time any filter is replaced before consumption.
