Recommended Filter Maintenance
The frequency in which the membrane and filters should be replaced depends upon the quality of the water
that enters the appliance. Every three to six months filter 1 and every six months filters 2, 4 should be replaced,
and every year filter 3 should be replaced (see Table on page 7).
Note: Any filter that demonstrates reduced water production or a slower rate of flow is overdue for a change.
Warning: Shut off water to the appliance before beginning any maintenance.
Replacement filter cartridge K5 (1)
Reduces dirt and other sediment particles matter 5 microns or larger in the incoming water. Every three to six
months the replacement of Replacement filter cartridge K5 is necessary.
Replacement filter cartridge K2 (2)
Reduces free chlorine from the incoming water and protects the membrane from chlorine degradation.
Changing the Replacement filter cartridge K2 should be based on the free chlorine levels in the incoming water.
If the free chlorine is 1 ppm or less, then the Replacement filter cartridge K2 should be replaced once a year. If
the free chlorine level is greater than 1 ppm, then the Replacement filter cartridge K2 should be replaced every
six months.
Membrane cartridge (3)
The semi-permeable RO membrane (3) separates the majority of the remaining suspended solids and most
of the dissolved solids from the water molecules. These separated impurities are then washed down the drain.
The RO membrane (3) is critical for effective reduction of total dissolved solids (TDS). The treated water
should be tested periodically to verify that the appliance is performing satisfactorily. A noticeable change in water
quality and taste may occur and indicates that a filter change is needed. Replace the membrane at least once
a year.
Note: The installation of the Drinking Water Machine appliance on a pre-treated water supply will greatly
increase the life of its filters.
Replacement filter cartridge K7M (4)
Replacement filter cartridge K7M (4) is the final stage of filtration. It filters the water and enriches it with useful
minerals that improve taste and correct drinking water salt balance. Replace the postfilter every 6 months.

Drinking Water Machine
Installation Guide
Installation and Maintenance Information
Checklist Before Installation
Refer to this checklist before installation.
The Drinking Water Machine is designed to be used for the treatment of municipally treated water or pre-
treated well water.
A water softener or additional types of pretreatment are highly recommended should your water not meet
water quality or characteristics standards.
□ Water Quality – If the water supply contains bacterial iron, algae, sulphur, tannins, organic matter, or
other unusual substances, then unless the appliance is represented as being capable of handling these
substances in the appliance specifications, other special treatment of the water supply must be used
to remove these substances before they enter this product. Consider purchasing and installing a water
conditioner or filter.
□ Water Pressure – Recommended 27.6–91.4 psi (1.9–6.3 bar).
□ 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 . See Installation Steps and Start-Up Procedures
□ Water Characteristics: pH – The appliance requires a pH of between 4.0 and 10.0 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.
□ Storage and Transportation – Shelf life of the Drinking Water Machine is 18 months at temperature
41–100.4°F (5–38ºC), in the polyethylene sleeve and cardboard package. It is necessary to store the DWM
assembly indoors with appropriate ventilation and relative humidity less than 80%. Avoid freezing, exposing
to sunlight, and mechanical impacts
Precautions
Do
1. Comply with all state and local building and plumbing codes.
2. Check all fittings and locking clips to ensure none are loose.
3. Install the appliance after the pressure tank on well-water installations.
4. Connect to the cold water supply only.
Do Not
1. Do not install if checklist items are not satisfactory. See Checklist Before Installation.
2. Do not install if the incoming water temperature exceeds 100.4°F (38°C). See Specifications.
3. Do not use to treat water that is microbiologically unsafe or of unknown quality without adequate disinfection
before or after the appliance.
4. Do not allow your appliance to freeze.
5. Do not expose your appliance to sunlight and mechanical impacts.
6. Do not tie into hot water supply.
