OPERATING PARAMETER
• Working pressure: 45 to 80 psi feed water pressure required. If input pressure is below 45 psi, use the systems with booster pumps.
If the input water pressure is above 80 psi (you must use a pressure regulator to step down the pressure). We also carry small
pressure regulators just for the RO system.
• Working temperature: 100 ~ 40 deg. F ( 37 ~ 4 deg. C )
• If feed water has hardness level above 300 ppm, we recommend putting a water softener prior to the RO system.
• If feed water has iron, rust problem, we recommend putting an iron filter prior to the RO system.
• If feed water has bacteria problem, we recommend putting an ultra violet sterilizing system prior to RO system.
WARNING: Do not use this RO+DI system alone to treat water with bacteria problem or water source with unknown quality.
WARNING: Do not connect HOT water source to this unit.
WARNING: Incorrect installation will VOID the warranty.
WARNING: Input pressure must not exceed 80 psi. Pressure regulator must be installed to reduce pressure.
WARNING: Using other brand of replacement filters and parts will void the warranty.
