Warning
Maximum water pressure (including any potential pressure spikes) of the water supply line to the
system must not exceed 80 PSI (5 .5 bar). Failure to comply will void the warranty. The
manufacturer accepts no liability for damage caused by excessive water pressure.
1. Always check local plumbing codes before tapping into water supply line and drain line. Tap
into the supply line with an approved connector.
2. Once the unit and filtration system flushing procedures are complete, determine the best
installation location. Consider user convenience, electrical access, and water access. The
unit performs optimally if within 20 feet of a cold-water supply line. Connect only to a
cold-water supply. Do not install Feed Water Assembly on the Hot Water Line. Do not
place unit where it will be exposed to rain, freezing temperatures or direct sunlight.
3. The rear of the unit should be installed at least 2” (5 cm) from any vertical surface to ensure
proper air circulation.
4. Use only ¼” OD copper or plastic tubing to connect your water supply and drain to the
cooler water inlet and drain port. The inlet and drain ports are quick connect fittings. Units
are shipped with plugs in each fitting. Remove the plugs prior to inserting water supply and
drain lines. A water shut off valve is recommended between the inlet connection to the
cooler and the water supply connection.
5. The W7 RO system requires a drain line for the RO membrane. The drain line should
include an Air Gap and back flow restrictor. See diagram.
6. Check the available power supply to assure proper electrical service. In the U.S., the
voltage specification is 110/120-volt 60 hertz. Voltage outside of this specification will
affect the system performance
7. Water filtration system must be flushed in accordance with the instructions. Once
operating, verify proper water production.
8. Be sure to dispense water from the hot tank prior to turning on the hot tank switch on the
rear of the unit. When ready, turn the Heating System switch on the back of the unit to the
“ON” position.
9. Perform final inspection of all installed water lines to ensure a leak free installation.
10. Instruct user on proper system operation.
