Instructions
1. Make sure the drip tray is in place before turning the unit on. Steam and condensation from the water tank is
released into the drip tray whenever the unit is on.
2. Turn the main power switch and control panel switch on.
3. When the diplay reads "READY", the unit has heated to the proper temperature.
4. Hold a cup or other container under the faucet and pull the faucet handle forward to dispense hot water. Larger
containers such as carafes, pitchers, or large mugs may be placed directly on the drip tray.
Operating Principles
When hot water is drawn from the faucet, the fill valve pulses on and off every few seconds to slowly refill the tank.
(See #60 - Fill Duty Cycle in the Programming section.)
By controlling the flow of incoming water, the amount of cold water entering the tank is synchronized with the rate
at which the water can be heated. This ensures an uninterrupted supply of hot water. When dispensing water at a
rate that exceeds the unit's capacity to heat, the flow of water out of the faucet will be diminished to maintain the
proper temperature.
Cleaning & Maintenance
Daily: Check the drip tray and empty if necessary.
Quarterly:
•
Inspect all fittings and hoses for leaks.
•
Inspect inside of tank for lime deposits. De-lime tank and probes if necessary. This procedure should be
performed by a qualified service technician.
