Pressure Switches:
The pump box unit is equipped with low and high pressure switches. The low pressure switch
shuts off the pump when there is no inlet water or its pressure is too low. The high pressure switch
shuts off the pump when the filtered water faucet is turned off and water storage tank is full.
Pump:
The pump box unit is equipped with a low voltage booster pump powered by the included
transformer 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 pump box inlet.
Faucet:
Designer faucet for filtered water is included and usually mounted on the sink deck or counter-
top for dispensing the clean, filtered water from the filtered water storage tank.
Water Storage Tank:
Air pressurized 4.0 gallon storage tank (with holding capacity up to 2.5G) is used for filtered
water storage.
Drain saddle:
Fits a standard 1.5” diameter drain pipe to drain the waste water from the drain outlet of the
pump box.
Pre-Filters:
The main R.O. unit has two pre-filters: sediment pre-filter on the first stage and activated
carbon 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.
