I NTRODUCTION
The SWPK Sheldon Water Purification Kit is designed to remove particulates and calcium from
water sources for the SHC10, SCH10R, SHC28, and SHC28R Humidity Chambers and their 230
volt variants, as well as the SCO26H and SCO26H-2 Humidified CO
2
Incubators*. The kit also
adjusts water pH and water resistance to levels that will not corrode the units’ interiors, or adversely
affect the performance of steamers and other major components. This installation guide covers how
to install the SWPK.
*These units were previously designated the HC9, HC9R, HC30, HC30R, and 2428H.
T AP W ATER
This purification kit is intended to purify standard tap water. Do not connect it to a deionized water
source. Use of deionized water will likely cause corrosive damage to major functional components
and the metal interior surfaces of humidity chambers and humidified CO
2
Incubators.
W ATER O UTPUT E XPECTATION
18 megohm-cm of resistivity can be achieved with the SWPK. The Absorber filter removes free
chlorine, organics, phosphate complexes, and turbidity. The Universal filter removes ionizable
constituents, except free carbon dioxide and silica. The Universal filter reduces the ion
concentration level equivalent to a single distillation.
W ATER P RESSURE
The SWPK is designed to work with tap water sources that provide 60 – 70 Pounds per Square
Inch of water pressure. Do not connect the SWPK to sources that exceed 120 PSI!
The regulator should be set to supply 5 PSI to the water filters.
