II. System Operation Parameters and Installation checklist
IMPORTANT! The following conditions for the feed water supply must be met or warranty will be void
and manufacturer assumes no responsibility for damage to system or property.
1. Water Temperature Parameters
• Maximum: 105º F (40.6º C)
• Minimum: 33º F (0.55º C)
WARNING: Do not allow the system to freeze, the membrane always contains water and will be
destroyed if frozen. Do not plumb system to hot water, The tubing will expand or burst, and membrane
will be destroyed which will void warranty and manufacturer’s responsibility.
2. Water Pressure Parameters
• Maximum: 75 PSI (5.27 kg/cm2)
• Minimum: 40 PSI (2.81 kg/cm2) / 0 PSI for system equipped with electric pump.
WARNING: This system is designed to operate at a water pressure in the range of 40 PSI to 75 PSI
(2.81 kg/cm2 to 5.27 kg/cm2). Operating at a pressure lower than the minimum required PSI will result
in lower quality and quantity of product water. Operating at a pressure higher than the maximum
allowed PSI will cause severe damage to the system.
WARNING: Do not proceed with the installation until water pressure is conrmed to be lower than 75
psi. A pressure regulator must be installed on the feed water source coming into the home to reduce
water pressure going into the system and ensuring water pressure does not exceeds 75 psi.
3. Water Condition Parameters
• Turbidity: <5 NTU
• pH: 4 - 11
• Hardness: < 7 grains per gallon (< 120 ppm)
• Sulde, Iron Manganese: < 0.01 ppm
• Chlorine: < 2 ppm
• Total Dissolved Solids (TDS): < 1,000 ppm
WARNING: If the hardness of your water is above 10 gpg (171mg/L), lime scale will build up rapidly
on the membrane. Scale buildup will plug the membrane and make the system ineffective. We do not
recommend this reverse osmosis systems be used with water in excess of 10 gpg (171 mg/L) hardness
unless the water is softened prior to the reverse osmosis system.
4. Pre-install environment checklist
• Installation needs to comply with state and local laws and regulations.
• System must be installed indoor away from possible environmental damage
• Do not use with water that is microbiologically unsafe or of unknown quality without adequate
disinfection before or after the system. Systems certied for cyst reduction may be used on
disinfected water that may contain lterable cysts.
• The system is best installed under the kitchen sink. But if that is not feasible, you can install the
system anywhere where there is a cold water supply with sufcient water pressure, and an outlet
to drain off the rinse water from the system.
