damaged during shipping. If any part is cracked or broken, please immediately contact PureDrop Customer

Recommended tools list
● Variable speed drill with two bits: ¼” for drilling a hole in PVC drain pipe (can be patched with duct tape
or PVC patch kit if no longer needed), ½” hollow diamond for drilling a hole in the countertop for the
drinking faucet
● 5/8”, 9/16” open-end wrench, or adjustable wrench, pliers

Operating conditions
● Maximum water pressure: 80 psi, otherwise a pressure regulator (part no. APR70) is required if there is
high water pressure or water hammer
● Minimum water pressure: 40 psi, or a booster pump is needed to improve the RO efficiency
● Water temperature: 40 – 100 °F (4 - 37 °C) (This RO system is NOT designed for HOT water). Within
the range, the warmer is the water, the faster is the RO process.

● Install this RO system in a location where it is safe from hot/cold weather and direct sunlight. Avoid
hitting, dropping, or dragging as these can cause cracks and leaks.
