About the reverse osmosis system.

How the Reverse Osmosis System Works

Reverse Osmosis reduces Total Dissolved Solids (TDS) and organic matter from water by diffusing it through a special membrane. The membrane separates minerals and impurities from the water and they are flushed to the drain. For the reduction of the claims specified, see Performance Data Sheet. High quality product water goes directly to the drinking water faucet or to the storage tank. The system makes a good supply of drinking water each day. How much it makes depends on the feed water supply pressure, temperature and quality.

The prefilter and postfilter are replaceable cartridges. The carbon prefilter reduces chlorine while also filtering sediments. The postfilter reduces any other undesirable tastes and odors before you use the water.

These systems include an electronic faucet assembly with a prefilter and postfilter change reminder, Reverse Osmosis membrane change reminder and a status okay reminder.

The prefilter and postfilter change reminder will flash amber after six months have passed or 900 gallons have been used. When this occurs, it is time to replace these cartridges and sanitize the system.

The membrane change reminder flashes amber when the TDS monitor in the system has measured the amount of impurities removed is less than 75%. When this occurs, it is time to replace this Reverse Osmosis membrane cartridge and sanitize the system.

Finally, a green flashing light will indicate the system is functioning properly.

Description of the Reverse Osmosis System

1 Prefilter—Water from the cold supply pipe is directed to the prefilter cartridge. The prefilter is a replaceable sediment cartridge containing activated carbon. The prefilter reduces chlorine in the feed water because CHLORINE DESTROYS THE REVERSE OSMOSIS MEMBRANE. Filtered, clean, chlorine-reduced water flows from the prefilter to the Reverse Osmosis cartridge.

2 Reverse Osmosis Cartridge—The middle cartridge includes a tightly wound, special membrane. Water is forced through the cartridge where the membrane reduces the dissolved solids and organic matter. For the reduction of the claims specified, see Performance Data Sheet. High quality product water exits the Reverse Osmosis cartridge and goes to the storage tank. Reject water, with the dissolved solids and organic matter, leaves the cartridge and is discharged to the drain through 1⁄4″ tubing.

3 Postfilter—After leaving the storage area, but before going

to the system faucet, product water goes to the postfilter cartridge. The postfilter is also a replaceable sediment cartridge that contains activated carbon. Any remaining tastes, odors or sediments are reduced from product water by the postfilter. Clean, high quality drinking water flows through the tubing and to the system faucet.

4 Storage Tank—The storage area holds up to 2-1/2 gallons of product water. A diaphragm inside the tank keeps water pressurized, when the tank is full, for fast flow to the faucet when drinking water is needed.

PNRQ21LRB, PNRQ21LBN specifications

The GE PNRQ21LBN and PNRQ21LRB are two advanced models from General Electric's line of innovative HVAC (Heating, Ventilation, and Air Conditioning) solutions. Designed with both efficiency and performance in mind, these units cater to residential and commercial needs, ensuring comfort in a variety of settings.

One of the standout features of the PNRQ21LBN and PNRQ21LRB is their energy efficiency. Both models utilize GE's cutting-edge inverter technology, which allows for variable speed operation. This means that the compressor can adjust its output based on the specific cooling or heating needs, leading to significant energy savings while maintaining optimal indoor climates. As a result, these units are not only environmentally friendly, but also cost-effective over time.

Another key characteristic is their quiet operation. The engineers at GE have invested in sound-dampening technologies that minimize operational noise, allowing users to enjoy a peaceful atmosphere, whether in a home, office, or commercial space. This is particularly beneficial for areas where noise sensitivity is crucial, such as bedrooms or conference rooms.

The PNRQ21LBN and PNRQ21LRB also come equipped with advanced air filtration systems. These systems effectively remove dust, allergens, and other airborne particles, contributing to improved indoor air quality. The filters are easily accessible for maintenance, ensuring that users can keep their systems running at peak performance with minimal effort.

User-friendly interfaces are another hallmark of these GE models. They feature intuitive control options that allow users to set schedules, adjust temperature preferences, and even monitor energy usage. This level of control empowers users to optimize their HVAC systems according to their lifestyle and needs.

In terms of design, both models boast a sleek and modern aesthetic, making them suitable for various architectural styles. They can fit seamlessly into any environment, enhancing the overall appeal of the space.

Overall, the GE PNRQ21LBN and PNRQ21LRB exemplify a blend of efficiency, quiet operation, advanced filtration, and user-centric design, making them ideal choices for anyone looking to enhance comfort and improve energy efficiency in their living or working environments.
