Consistent and superior quality sets us apart from other manufacturers and increases our value to you - our customer. Whether you are a hydroponics hobbyist, serious enthusiast, or large-scale gardener, GrowoniX is committed to bringing you the best solution for water purification systems. WHAT IS REVERSE OSMOSIS? Reverse osmosis (RO) is a filtration method that removes many types of large molecules and ions from solutions by applying pressure to the solution when it is on one side of a selective membrane. This filtering process ensures that the solute (waste water) is contained within the pressurized chamber while the pure solvent (RO water) is allowed to pass freely through the membrane. TUNED FOR GROWING - IN TUNE WITH OUR CUSTOMERS Traditional RO systems have waste ratios of approximately 4:1, which means there are 4 gallons of waste water produced for every 1 gallon of purified water. GrowoniX line of water filters achieve waste ratios of 2:1 with all 200-400 GPD systems, and an astounding 1:1 ratio with the 600-1000 GPD systems. GrowoniX has created a complete product line that will address the needs of hydroponic operations of all sizes. Our filters will significantly reduce your water use while dramatically increasing your yields. THE TRADITIONAL WAY takes 4 gallons of waste water to produce 1 gallon of pure water THE GrowoniX WAY 2 20 GPM Water Flow Rate Stack Multiples for Added Flow Rate Auto Shut-Off Circuitry under 0.7GPM..

Ensure the mains voltage is the same as the value shown on the motor plate and that the pump is safely connected to ground/earth. 2. The single phase models are supplied with plug and lead and can be connected directly to the mains supply. The 3 phase models should hook up with a circuit breaker. WARNING Risk of electric shock - This pump has not been investigated for use in swimming pool or marine areas. · To reduce the risk of lectric shock, connect only to a properly grounded, grounding-type receptacle. · Before operation, please ensure the voltage is correct and the circuit breaker and grounding · connectors are all connected in accordance with local regulations.

Replace the filling plug Before starting, the pump must be primed. For installation with no inlet pressure, please follow the procedure as shown in Fig. 8. 1. For installation with inlet pressure, remove the priming plug and allow the water to flow into the priming chamber until all air is expelled. 2. The priming procedure should be repeated until all air is expelled and the pump delivers a full stream of water without bubbles. 3. The pump must always be checked for prime if not used for a prolonged period. It is imperative to fill the pump with liquid before operation as dry running causes irreparable damage to the mechanical seal. Built in the U.S.A. Torque: 26 in-lb FFiigg.. 86 7 INSTRUCTIONS CONT.

WHAT CAUSES THE DDP-20 TO START? The DDP-20 has the built-in pressure switch and internal flow switch. Each of these can turn the pump on depending on water consumption. The pump will start when: - The pressure is BELOW the pressure switch activation point. OR - The flow rate is greater than 0.7 GPM. 2. WHAT CAUSES THE DDP-20 TO STOP? The flow switch is designed to automatically stop the DDP-20 when flow drops to below 0.7 GPM. The DDP-20 is programmed to stop after 8 seconds. In addition, the DDP-20 will be turned off in the event of dry-run or over temperature alarm. 3. WHAT IS THE PURPOSE OF THE BUILT-IN PRESSURE TANK? The pressure tank comes from the factory pressurized at approximately 20 psi (with the pump pressure at zero). It is designed to minimize motor startup due to small flow demand or minor leak of the pipeline. 4. HOW IS THE DRY-RUN CONDITION DETERMINED AND THE PROTECTION PROVIDED? The dry-run is defined when the motor is running AND the flow rate is less than 0.3 GPM AND when pressure is less than the pressure switch setting. The protection is provided: · When the pump is run dry 2 minutes, it will automatically shut off for 10 minutes and then attempts to restart. · When all 3 attempts are failed, the pump will rest for 1 hour and then attempts to restart. · This protection mode will be repeated until the water supply is back to normal. In case the pump is cycling (on-and-off repeatedly) due to small flow (less than 0.3GPM), air pocket in the system, air loss in the pressure tank or leak in the pipeline, the protection is provided: · The pump will run for 8 seconds and stop for about 3 seconds. · When the cycling mode repeats for 15 times consecutively, the pump will rest for 1 hour. · Then it will start over the protection mode until the problem is corrected. Note: The pump can be reset anytime by removing the power plug. 5. WHAT IS THE MAXIMUM INLET PRESSURE ALLOWED IN THE DDP-20? · The maximum internal system pressure allowed for DDP-20 is 120 psi. · The maximum inlet pressure when added to the DDP-20 pressure must not exceed 120 psi. For example with a 40 psi inlet pressure supplied to the pump, internal system pressures can reach approximately 107 psi (67 + 40 psi). Additionally, if inlet pressures exceed the built-in pressure switch activation point (20 psi factory default), the pressure switch will be unable to function, and the ability to turn the DDP-20 on at low flow rates will be lost. In this situation, only the flow switch will be able to turn the DDP20 on at flow rates above 0.7 gpm.
