Feedwater Requirements
See safety information regarding reducing the risk associated with property damage due to water leakage or fl ooding on page 4 prior
to set-up and installation of the system.
• Be sure to confi rm that the feedwater falls within the limits shown below. If unsure of the feedwater quality, check with your 3M
Products distributor.
Challenge Water Recommendations
(Contact dealer/distributor for assistance in water testing)
If there is iron or manganese above recomended limits present in the incoming-water, it is recommended to install water softening system upstream
™
of ScaleGard
HP System.
If incoming water hardness is greater than 10 grains (171 mg/l), it is recommended to install water softening system upstream and change the stan-
dard fl ow control on the drain-line to achieve recovery of the RO system at 33%. (HFRO 33% Recovery kit PN-50-93201)
If the particle count is >1000 counts/ml for particles less than 2 micron size or turbidity is greater than the recommended 5 ntu limit, then it may be
required to consider different prefi ltration options and change the standard fl ow control on the drain-line to achieve recovery of the RO system at
33%. (HFRO 33% Recovery kit PN-50-93201) . Contact your dealer/distributor for details.
It is recommended to install an SGHP RO-EXP and SGHP Pre-EXP under the following conditions:
1. If more production capacity is needed.
2. If installed in a location where water temperature drops below 50 °F (10 °C) during any part of the year.
3. If the particle count is >1000 counts/ml for particles less than 2 micron size or turbidity is greater than 5 NTU limit.
4. If the incoming water TDS is greater than 1000ppm limit.
