    APEX 150 SERIES BOOSTER PUMP Conversion Kit

    Reverse osmosis filtration systems work on the principal of forcing water through a spiral-wound semi-permeable membrane. Reverse osmosis filtered water is often called “fresh squeezed” because it is literally squeezed through the RO membrane. Salts, like sodium, chloride and potassium along with nitrate, sulfate, lead and other contaminants can’t pass through the membrane and get flushed or “rejected” down the drain as waste water, while purified water is collected in the water storage tank. Many water supplies suffer from low or inconsistent water pressure. Well pumps may not be able to maintain the proper water pressure for an RO filtration system. Even some municipal water systems have unsuitable water pressure. If you live in an apartment or high-rise building your water pressure can fluctuate as water use increases throughout the facility. This may cause your reverse osmosis filter system to stop working or work very poorly. If the water pressure is below 30 PSI, the RO system will send more water to waste than is necessary. The water purity of the filtered water can also decline because the reverse osmosis membrane cannot function properly.

    The APEX 150 Booster Pump can be used to correct a low-pressure condition or replace a broken booster pump. The APEX 150 booster pump is a direct fit replacement for APEX reverse osmosis filters. The APEX 150 Booster Pump uses a safe 24-volt low-voltage transformer to provide electric power the pump. The booster pump increases the incoming water pressure to the ideal 80 PSI. This water pressure level maximizes the number of gallons produced per day while minimizing the amount of wastewater sent to the drain. The APEX 150 Booster Pump is designed in the United States and manufactured with high-quality components that will provide years of trouble-free service.

    The booster pump installation can be performed as a DIY project. We advise installation by a licensed plumber to ensure adherence to all local codes.

    Installation Instructions
    Turn Off the Main Water Supply Line

    Be sure to run only cold water through the unit

    Turn off the main water supply line or the cold-water shutoff valve underneath the sink (if installing under sink).

    Space Your Components

    Position the pump, pressure switches, solenoid, conforming to Figure 1.2 below, so that the 1/4” tube that supplies water to the unit can be routed through them. Observe the directional arrows on the quick-connect fitting ports, cut the inlet tube squarely and insert the ends into the appropriate ports.

    • AWater supply adapter valve
    • BCold water shut-off valve
    • CAuxiliary faucet
    • DGarbage disposal
    • EPre-carbon filter sumps
    • FDrain Saddle
    • GStorage tank with valve in open Position
    • HPre-filter sump
    • IMembrane assembly
    • JPost-filter
    • KPump
    • LOptional UV/DI/Alkaline Stage
    Electrical Connections3

    Connect the electrical wires from the power supply into pressure switches, solenoid and pump conforming to Figure 1.3 below.

    Check for Leaks

    Turn on the water supply adapter and check for leaks. Turn on the tank. The unit should now start producing water through the drinking water faucet. Plug in the power supply to the electrical outlet. Water supply through the faucet should increase. Pump will turn off automatically when the tank is full and resume operation when the tank gets depleted. Check for leaks! Make sure there is no leaking at joints, fittings, valves, and tubing connections.
