Checklist Before Installation

Refer to this checklist before installation.
WaterMax® H3000 and H3500 are designed for chlorinated municipal water supplies.
AWaterMax® Water Softener or additional types of pretreatment are highly recommended should your water
not meet water quality or characteristics standards. Should you have any questions about your water not
meeting these standards, contact your Hague dealer.
Water Quality—If the water supply contains sand, sulfur, bacteria, iron bacteria, tannins, algae, oil, acid, or
other unusual substances, consider pre-treating the water to remove these contaminants before the water
supply enters the appliance, unless the appliance is represented as being capable of treating these
contaminants in its specifications. Consider purchasing and installing a WaterMax® water conditioner or filter.
Water Pressure—Not less than 40 psi constant for WaterMax® RO appliances.
Drain—Drain the appliance to an appropriate drain, such as a floor drain or washer drain that complies with all
local and state plumbing codes. To prevent back-siphoning, provide an adequate air gap or a siphon break.
See Installation Steps and Start-Up Procedures.
Water Characteristics: pH—The appliance requires a pH of between 5.0 and 9.0 for H3000 and H3500
models and between 4.0 and 11.0 for other models to function properly.
Water Characteristics: Iron and/or manganese—A test to determine iron or manganese levels is necessary.
Should iron exceed 0.1 ppm, or manganese exceed 0.05 ppm, additional pretreatment is recommended.
If you have any questions, contact your Hague dealer.
