IMPORTANT NOTE:
The pH Neutralizing / Remineralizing Cartridge is there to increase the normally low pH (acidic) condensate water. In
order to increase the pH, it also adds a certain amount of calcium carbonate, which increases the PPM/EC of water. As
an example, if your condensate water is pH 6.0, the product water from the ARCS will be between 7.0-7.4 pH. Since the
Heavy Metal Reduction Cartridge (stage 2) removes all PPM/EC, the product water after stage 3 will be between 40-75
PPM (0.06-0.1 EC) of calcium carbonate.
If you find your condensate water is within an acceptable range of pH before
treatment and/or if you do not want any calcium carbonate in the product water, simply remove the stage 3 cartridge
and leave that canister empty.
INSTALLATION GUIDE
The ARCS consists of the 3-stage Cartridge assembly, and 4th stage UV sterilizer mounted to the top of the bracket. The
ARCS is designed to be placed on a level surface via its heavy duty floor stand or mounted to the wall as an option. The
customer supplied pump should be placed within a 10-foot range of the ARCS.
1. Prior to installation, inspect the ARCS for damage during shipping and call Hydrologic to report any issues.
2. Shut down the HVAC system prior to plumbing.
3. Redirect the condensate runoff of the HVAC system(s) into a reservoir or storage tank of your choice. The
customer supplied pump should be inline style, and must be able to handle system backpressure. The ideal
flow rate of this pump should be 2 gallons per minute (GPM) with high head height. The ARCS has a flow
restrictor that is set for 2 GPM so the water has enough contact time with the filters. Install the grey fitting on
the left side of the unit.
DO NOT
over-tighten.
4. Assemble and insert the UV lamp and Quartz sleeve (if needed) into the body of the UV as shown in the
UV Installation Assembly on page 4.
5. Plumb the outlet from the UV Filter to the reservoir or storage tank using all or part of the included blue
