PRODUCT SPECIFICATION 
5- Stage Reverse Osmosis Water Purification Systems 
Model no:  RO585 
Capacity:   Generates 45 to 85 gallons per day depends on water temperature, pressure, chemistry variations)  
System includes 
•  RO unit: 5-stage unit, all filters included. 
•  Storage Tank: Pressurized tank with pre-charge pressure of 7~10 psi., powder coated steel construction with Food 
Grade butyl water bladder. NSF listed 
•  Water Dispensing Faucet: lead-free, long reach goose neck type, chrome steel, locking lever for continuous dispensing. 
•  Hardware: feed water adapter, feed water valve, drain saddle valve, tank valve, and screws.  
•  Installation & Service manual 
System Requirements 
•  Working pressure: 40 to 80 psi feed water pressure required, if below 40 psi, a booster pump is needed. We have a RO 
system with booster pump assembly. If the input pressure is above 80 psi, you MUST put a pressure regulator to reduce 
the pressure below 80 psi. 
•  Working temperature: 100 ~ 40 deg. F ( 37 ~ 4 deg. C ) 
•  pH range: 2-11 
•  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 a 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.
