Feedwater Requirements
See safety information regarding reducing the risk associated with property damage due to water leakage or flooding on page 4 prior
to set-up and installation of the system.
• Be sure to confirm 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.
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
additional pre-filtration may be required. 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 1000 ppm limit.
