There are two ways water can contain impurities: The product is designed to be installed indoors, in suspension or in solution. - Page 12 Page 12 Page 12 Water Filters Horizontal runs of drain tubing need a 1/4" fall per foot of run for proper draining. If connecting to water filtration, filter only the water to the reservoir, not to the condenser. Follow all applicable codes. Install a new cartridge if the filters were used with a prior machine.
