EHS Series

The R.O. system contains the following 5 stages:

1. Stage 1 is a 20 Micron Particular Filter that removes dirt, sediment, sand, and other physical particles.
2. Stage 2 is a 5 Micron Particular Filter to remove small particles such as dirt, sediment, sand and other physical particles.
3. Stage 3 is Activated Carbon which reduces chemicals, such as chlorine, that may be in your water supply.
4. Stage 4 is the Reverse Osmosis Membrance which reduces 93%-98% of dissolved mineral salts and other containates in your potable water supply.
5. Stage 5 is a Post Carbone Filter which performs a polishing process that remove undesirable tastes and odors from the wate

" Mounting of the filter unit: 2-1/4" horizontally slotted holes, 10 5/8" on center,
13" up from the bottom of the filter cartridges

a) Filter unit 8"W x 17"L x 18"H
b) Storage Tank 10.3 gal, 16" dia x 18"H

Weight: Filter unit 15 lbs (dry)

Tap Water Supply: The unit is supplied with 6' of ¼" O.D. x 11/64" I.D. poly tubing. A saddle valve (not supplied) is required to complete the connection to the cold water line.

Output Line: The unit is supplied with 6' of 3/8" O.D. x ¼" I.D. poly tubing. Using a saddle valve to supply tape water to this R.O. system eliminates the need for an additional shut off valve behind the EHS, as noted above. In which case an adapter 3/8" compression x ½" NPT (male) would be needed to connect the output poly tube to the hose coming off the EHS.

Drain line: The unit is supplied with 6' of ¼" O.D. x 11/64" I.D. poly tubing. The drain line can be routed into the same drain as noted above for the EHS unit or a drain outlet saddle (not supplied) can be used to connect the drain line to a suitable waste line.

Storage tank: A 10.3 gal tank with a floor base is supplied. A ¼" NPT x 3/8" O.D. 90 degree elbow fitting is required (not supplied) to connect the tank to the poly tube from the filter unit, when the tank and the filter system are located at the same approximate height. If the filter system is located higher than the tank a straight fitting should be used. The unit is supplied with 6' of 3/8" O.D. x ¼" I.D. poly tubing.

Maximum distance: from the tank to the EHS is 15 feet. Longer distances will result in a reduced flow rate.

One R.O. system is required per autoclave
