LED indicators

 

A – The heater is on. Indicator will turn off when hot 

water temperature reaches 200 °F (95 °C) or heater is 
turned off manually.

 

B – The dispenser is plugged into the mains.

 

C – The cooler is on. Indicator will turn off when cold 

water temperature drops below 50 °F (10 °C) or cooler 
is turned off manually.

Pressure and Level Switches:

The dispenser is equipped with low pressure switch and water level switch. The low pressure 
switch shuts off the pump when there is no inlet water or its pressure is too low. The water 
level switch shuts off the pump when heater and cooler are full.

Pump:

The dispenser is equipped with a low voltage booster pump powered by the included trans-
former for safe operation. 

Inlet valve:

An adapter ball valve is included to be installed into the cold water supply line to feed water 
to the dispenser inlet.

Drain saddle:

Fits a standard 1.5” diameter drain pipe to drain the waste water from the drain outlet of the dispenser. 

Pre-Filters:

The dispenser has two pre-filters: sediment pre-filter on the first stage and activated car-
bon pre-filter on the second stage. They provide initial filtration of the water and protect the 
following thin film composite R.O. membrane from dirt and aggressive chemicals such as 
chlorine often found in tap water.
