System Installation
Prior to Installation
*Installation is to comply with all local laws and regulations*
Inspect the package
Open the box and remove all of the components. Inspect them to ensure nothing was damaged
during shipping. If any part is cracked or broken, please immediately contact iSpring Customer
Support for a replacement. Identify and get familiar with the components.
Recommended tools list
● Variable speed drill with two bits: 1/4" (for drilling a hole on PVC drain pipe), 1/4" hollow
diamond (for drilling a hole on the countertop for drinking faucet)
● 5/8", 9/16" open-end wrench, or adjustable wrench, pliers
● Phillips head screwdriver
● Scissors or utility knife
Operating conditions
● Minimum recommended water pressure: 30 psi
● Maximum water pressure: 70 psi; otherwise, a pressure regulator (model: APR70) is
required to lower the psi to the maximum level.
● Operating water temperature range: 40 – 100 °F (4 - 37 °C) (This RO system is NOT
designed for HOT water). The RO process will be faster and more efficient within the
operating range with the water temp on the warmer side and less so on the colder side.
● Maximum TDS: 750 ppm
● Install this RO system in a location where it is safe from hot/cold weather and direct
sunlight. Avoid hitting, dropping, or dragging the system, as this can cause cracks and
leaks.
