(D) Water Quality Parameters
The unit should be operated with water that meets the following minimum criteria. Source water exceeding chemical
parameters (listed below) requires pre-treatment.
Raw Water Supply
Chemical Parameters

1
Do not use with water that is microbiologically unsafe or of unknown quality, without adequate disinfection before or after the system. Systems
certified for cyst reduction may be used on disinfected water that may contain filterable cysts. For effective disinfection we recommend Rainfresh
Whole-house UV disinfection systems.
2
Install a pressure regulator and water hammer arrestor if pressure exceeds maximum rating at any time.
Note:
If daytime pressure is over 80 psi, night
time water pressure may exceed pressure rating.
Water pressure lower than 45 psi will cause drop in filtered water production rate. If water
pressure is at any time lower than 45 psi, an RO booster pump is required.
Call Rainfresh to order.
3
System will operate with hard water, but membrane life will be shortened
4
TDS > 1,000 PPM may require booster pump.
5
Average efficiency rating - 9.1% - Efficiency rating means the percentage of the influent water to the system that is available to the user as RO treated
water under operating conditions that approximate typical daily usage.
Average recovery rating - 18% - Recovery rating means the percentage of the influent water to the membrane portion of the
system that is available to the user as RO treated when the system is operated without a storage tank or when the storage tank is bypassed.
