PRECAUTIONS READ ENTIRE MANUAL THOROUGHLY BEFORE INSTALLING THIS HIGH PRESSURE-BOOSTING PUMP. CAUTIONS • • • • Do not operate the pump above the pressure limitations specified on the data label. Never operate the pump in a harsh environment or hazardous atmosphere, since motor brush and switch may cause electrical arcing. Consult with the factory if the pump is to be used with fluids other than water. Do not use with flammable or hazardous fluids.
ELECTRICAL • The DDP-4 Vari pump is designed for intermittent duty, but may run continuously if the motor temperature does not exceed the recommended limit. • DDP Series Pumps are equipped with thermally protected motors, and in case the motor temperature exceeds the thermal cut-out rating, the pump will shut down, and will not restart until motor cools down to specified temperature.
GUIDELINES OPERATIONAL & INSTALLATION GUIDELINES READ CAREFULLY BEFORE INSTALLING THE PUMP. • The basic demand pump is controlled by a built-in pressure sensing demand switch. • When a faucet or valve is opened down stream of the pump, line pressure drops thus starting the pump automatically. Conversely, when the valve shuts, the line pressure increases turning the pump off automatically. • The pressure switch actuates in response to the pump outlet pressure at a predetermined and preset pressure.
ADJUSTING THE PRESSURE SWITCH (ALTHOUGH SHOULD NOT BE NECESSARY). • ADJUSTING THE PRESSURE SWITCH. Should the pressure switch OFF setting vary with use and time to an unsuitable value, it may be adjusted for optimum performance. Turn the set screw clockwise to increase the OFF pressure setting and counter clockwise to decrease. The screw should not be adjusted more than one turn without consulting the Factory.
GROWONIX SYSTEM WARRANTY For a period of one year from the date of original purchase, we will replace or repair any part of the GrowoniX product that we find to be defective in operation due to faulty materials or workmanship with the exception of the replaceable filters and membranes.
