1. Carefully unpack the hot water dispenser and check for damage and missing parts.
2. Place hot water dispenser on sturdy, level, heat resistant, non-flammable surface near power supply
and water supply. DO NOT connect water line or power cord at this time.
3. Make sure the unit is positioned with at least 6" of space on the right side for easy access to controls.
4. The unit comes with a 3/4" thread to 1/4" flare connection adapter.
5. Attach the water line to the inlet located on the rear of the dispenser. Hold the water inlet fitting with a
wrench when tightening the water line.
NOTE: Total Water Hardness - Minimum 3 CPG, Maximum 5 CPG
6. Turn on the water supply. Make sure to check for leaks at the water inlet. Tighten fitting if necessary.
NOTE: The dispenser is designed to operate with a water between 30 and 70 PSI. When water
pressure exceeds 70PSI, it is recommended that an optional regulator be installed to reduce water
pressure.
7. Connect power supply cord into proper power supply as indicated on the nameplate of the machine.
Make sure the machine is switched OFF before connecting to the power supply.
NOTE: Please use filtered and softened water. If using ground or tap water, please soften it first.
Unsoftened water will decompose dissolvable minerals and turn into limescale after boiling.
The limescale will reduce the machine's thermal eciency and lifetime.
NOTE: We recommend installing a water filtration system such as the C Pure Oceanloch-L Water
Filtration System & Pressure Gauge (790OCLOKITLG) to prolong the life of the unit.
