Most water supply authorities have strict regulations regarding connection to mains water supplies, please adhere to those regulations. Do not exceed to Davey pump operating pressures, Davey Water Product Pty Ltd cannot accept responsibility for loss or damage resulting from incorrect installations. -
Page 5: Above Ground Water Sources (Flooded Suction)
3.2 Above ground water sources (flooded suction) The DynaDrive DD15-35NPT model comes factory set to 60psi to suit boosting applications, please note for flooded suction and suction lift applications the factory set pressure will need to be reduced to prevent a dry run situation. Also note the pressure tank will also require adjustment to 70% of the set pressure. -

This will assist laminar flow. Figure 4.2 4.3 Air Handling While Davey must stress the overall requirement for all suction lines to be airtight, we also are aware that sometimes removing air from suction lines or stopping minor leaks can be difficult. -
Page 7: Power Connection
• Ensure motor is connected to power supply specified on nameplate; • Although the Davey electric motor is specifically engineered to perform on a range of power supply voltages, malfunctions or failure caused by adverse voltage supply conditions are not covered under guarantee. -
Page 8: The Pressure Tank
4.5 The pressure tank IMPORTANT: Air pressure in pressure tank should be set to 70% of the DynaDrive set pressure. For example, the pressure that DynaDrive comes pre-set to is as follows: DD15-35NPT 414kPa (60psi); DD60-10NPT 414kPa (60psi); DD90-11NPT 414kPa (60psi). The default air pressure of the pressure tank used with DynaDrive should be set to: DD15-35NPT 290kPa (42psi);... -

6.1 Start-up procedure After power is initially turned on to the DynaDrive, the display shows the software version and the name Davey, see figure 6.1. All LEDs flash for the initial ~ 5 seconds. The Power LED will remain lit green, showing the DynaDrive has power. - Page 11 The display then reverts to the HOME SCREEN, see figure 6.2. The Power LED will show bright green. The display shows the pre-set pressure (psi) on the top line, shown in Figure 6.2, and pressure (psi) being measured by the DynaDrive pressure transducer on the bottom line, shown in Figure 6.2. The default unit of measurement is psi: Pset 60 Pact 0...

Page 12: Manual Override
In addition to automated control, DynaDrive can also be run in manual override on, should the need arise. IMPORTANT: It should be noted that when the pump is manually turned on, the automated protection built into DynaDrive is overridden. Davey recommends use of the manual override only when absolutely necessary and only for a short time period. - Page 13 Pset 60 Pact 60 Figure 6.5 Prime button. The pump will turn on and continue to run until the • Press and hold the Prime button is released, see figure 6.6; While the pump is in manual override the Prime LED will illuminate orange, see figure 6.6.

6.4 Changing the set pressure IMPORTANT: WHEN ADJUSTING SET PRESSURE, DO NOT EXCEED THE PRESSURE CAPABLE OF THE DYNADRIVE IN THE INSTALLATION. REFERENCE TO LOCAL REGULATIONS SHOULD ALSO BE CONSIDERED. When changing the set pressure of DynaDrive, the pressure of the pressure tank must also be adjusted. Refer to section 4.5 pressure tank, of the installation chapter. - Page 16 pressure 60 Psi Figure 6.10 • If the controls are untouched for ~ 30 seconds, the menu will revert back to normal display; • To change the set pressure, use the Menu up button or Menu down button.

Page 21: Using A Switch To Override Dynadrive Operation
7.3 Using a switch to override DynaDrive operation DynaDrive has the ability to be overridden by a separate switch. This may be of benefit if using a float switch on a source tank (eg rainwater tank). To wire in an independent switch, refer figure 7.5 and 7.6. For model DD15-35NPT ~1 110V or all other models ~1 230V... - Page 22 To set the DynaDrive to recognize the remote switch: • Ensure automated control is turned off. To turn the automated control off, push the Automatic on / manual off button. • The green Automatic LED will turn off, see figure 7.7; Pset 60 Pact 60 Figure 7.7...
- Page 23 DynaDrive controller. The normally open terminals will not trigger fault/alarm/pause conditions. When the terminals are closed circuit, the DynaDrive operates normally. Davey recommends a float switch cable no longer than 3m (10 feet), when using 2 x 0.25mm (24 AWG) cable. If the switch overrides DynaDrive to pause, the DynaDrive display will show a flashing Fault LED.
