DynaDrive ™ Congratulations on your purchase of a high quality, Davey DynaDrive constant pressure system. All components have been designed and manufactured to give trouble free, reliable operation. Contents 1. PRIOR TO USING THIS PRESSURE SYSTEM, YOU MUST ENSURE THAT...........................................3 2. YOUR NEW SYSTEM..................................................................................................................................3 3. APPLICATIONS...............................
CAUTION: This pump has been evaluated for use with water only. Do not insert any object in the opening. Before using this pump, the pump must be well installed. Children should be supervised that they do not play with the pump. NPT model variants acceptable for indoor use only, do not used outdoor. For use with maximum 80°C (176°F) water. WARNING: Risk of electric shock. This pump is supplied with a grounding conductor and grounding-type attachment plug.
3. APPLICATIONS 3.1 Above ground water sources (flooded suction) Figure 3.1 Installations with flooded suction require a gate valve so water supply can be turned off for pump removal and servicing, see figure 3.1. There is no need to install a one-way check valve in the suction pipeline as there is a one-way check valve installed in the tee piece immediately on top of the DynaDrive pump discharge. 3.
3.5 Installs with a mains pressure hot water system ATTENTION: Always ensure hot water systems are installed in compliance with manufacturers recommendations and in accordance with all local regulations. To protect your system from damage caused by back pressure from hot water systems, see figure 3.5. You should always have installed on the hot water inlet an approved non-return valve.
4.3 DynaDrive with air handling capacity Your DynaDrive has the benefit of a new upgraded self-priming and air handling capability. 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. For this reason, Davey have incorporated special features into your new pump or pressure system to make operation easier and more dependable.
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: DD60-10(CE) 400kPa (58psi); DD90-11(CE) 400kPa (58psi); DD60-10NPT 414kPa (60psi); or DD90-11NPT 414kPa (60psi).
5. FEATURES 5.1 System features • Provides warning indications for system faults; • Has adjustable pressure setting to allow for various operating conditions; • Provides automatic “cut-out” protection should the pump run out of water, should the pump fail to start due to low voltage or a blockage in the pump; • Enables the pump to deliver a constant pressure of water particularly across a wide range of flow rates – reducing the inconvenience of pressure variation in showers etc.

Power LED will show bright green. The display then reverts to the HOME SCREEN, see figure 6.2. The The display shows the pre-set pressure on the top line, shown in Figure 6.2, and pressure being measured by the DynaDrive pressure transducer on the bottom line, shown in Figure 6.2. The default unit of measurement is as follows: * DD60-10(CE): kPa; * DD90-11(CE): kPa; * DD60-10NPT: psi; or * DD90-11NPT: psi. P/N:16115-1 B Pset 400 Pact 0 Figure 6.
Automatic LED will illuminate bright green indicating that the pump is running • The Once the set pressure has been achieved, the DynaDrive will slow the motor speed. If the pressure drops below set pressure, the motor speed will increase again to maintain pressure. However, if the pressure does not drop below set pressure, the motor speed will continue to decrease, until it’s off. Automatic LED will flash green to indicate the pump is in standby maintaining pressure, see The figure 6.4.

The pump will turn on and continue to run until 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. P/N:16115-1 B Pset 400 Pact 420 Figure 6.
6.3 Main menu display After initial startup, pressing the Menu up button will allow display to scroll through the following: • Frequency (Hz); • Outgoing current per phase from the DynaDrive to the pump’s motor (Amps); • Temperature of the DynaDrive (°C). To change the display: • Press the Menu up button; • The display will continue to show the pressure set, but changes from showing actual pressure, to the frequency of power supplying the motor, see figure 6.7.
6.4 Changing the set pressure IMPORTANT: WHEN ADJUSTING SET PRESSURE, DO NOT EXCEED THE PRESSURE CAPABLE OF THE DYNADRIVE IN THE GIVEN INSTALLATION. REFERENCE TO AS/NZS 3500/2003 (OR LOCAL EQUIVALENT) 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. The set pressure cannot be changed while the pump is running, or in automatic mode.

P/N:16115-1 B pset 300 pact 380 Figure 6.12 • Now restart automatic operation by pressing Automatic on / manual off button. 6.5 Extra draw-off capacity The DynaDrive has a pressure tank included as part of the system which will accommodate small leaks. In some applications it may be appropriate to install an additional (or larger) accumulator (pressure tank) capacity.
7. ADVANCED SETTINGS 7.1 Changing cut-in pressure point The default cut-in pressure of DynaDrive is 50kPa (7psi) less than set point. This can be changed by: • Ensure automated control is turned off. To turn the automated control off, push the manual off button. • The green Automatic on / Automatic LED will turn off, see figure 7.1; P/N:16115-1 B Pset 400 Pact 400 Figure 7.1 • Once the motor has slowed to a stop, press and hold the Menu button and Enter button for ~ 5 seconds.
• If the controls are untouched for ~ 30 seconds, the menu will revert back to normal display; • Using the Menu up button and Menu up button and • Use the pressure variance; • Press the Menu down button scroll through to Cut-in; Menu down button to change the setting to adjust the cut-in Enter button to save settings and return to the HOME SCREEN; • Now restart automatic operation by pressing Automatic on / manual off button.

Menu down button to change the setting to. The setting will Enter button to save settings and return to the HOME SCREEN; • Now restart automatic operation by pressing Automatic on / manual off button.
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. Figure 7.5 Figure 7.
To set the DynaDrive to recognize the remote switch: • Ensure automated control is turned off. To turn the automated control off, push the manual off button. • The green Automatic on / Automatic LED will turn off, see figure 7.7; P/N:16115-1 B Pset 400 Pact 400 Figure 7.7 • Once the motor has slowed to a stop, press and hold the Menu button and Enter button for ~ 5 seconds. The display will change to show your current set pressure, see figure 7.8; P/N:16115-1 B pressure 400 kPa Figure 7.
• If the controls are untouched for ~ 30 seconds, the menu will revert back to normal display; • Using the • Use the • Press the Menu up button and Menu up button and Menu down button scroll through to LEVEL; Menu down button to change the setting to Y; Enter button to save settings and return to the HOME SCREEN; • Now restart automatic operation by pressing Automatic on / manual off button.
7.4 Daisy-chain multiple DynaDrive systems It is possible to run two DynaDrive pumps in parallel, with a shared discharge line. This can be particularly useful in applications where the system’s maximum flow rate can be significantly higher than the system’s minimum flow rate. For example: if DynaDrive needed a flow rate demand of up to 140L/min (37 gallons/min) at a pressure of 400kPa. Running two DynaDrive DD90-11 systems in parallel with common discharge would accommodate this.
