ATTENTION: The DynaDrive system and associated pipework operate under pressure.
Under no circumstances should the DynaDrive system, or associated pipework be
disassembled unless the internal pressure of the system has been relieved. Failure to
observe this warning will expose persons to the possibility of personal injury and may
also result in damage to the pump, pipework or other property.
Prior to installation remove the inlet and outlet pipe transport plugs & associated seals from the suction
and/or discharge ports.
1. PRIOR TO USING THIS PRESSURE SYSTEM, YOU MUST ENSURE THAT
• The pump is installed in a safe and dry environment
• The pump enclosure has adequate drainage in the event of leakage
• Any transport plugs are removed
• The pipework is correctly sealed and supported
• The pump is primed correctly
• The power supply is correctly connected
• All steps have been taken for safe operation
Appropriate details for all these items are contained in the following Installation and Operating Instructions.
Read these in their entirety before switching on this pump. If you are uncertain as to any of these Installation
and Operating Instructions, please contact your Davey dealer, or the appropriate Davey office as listed on
the back of this document.

3. APPLICATIONS
MAINS WATER
3.1 Above ground water sources (flooded suction)
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.
3.2 In-ground water sources (eg suction lift from in ground tank)
Figure 3.1
Whenever the installation position of the pump is higher than the lowest
water level, a foot valve should be fitted to the end of the suction pipe,
see figure 3.2. Ensure that the foot valve is at least ½ metre below
minimum water level to avoid a vortex of air being drawn into pipe. In
these applications the foot valve must replace the one-way check valve
that’s installed in the tee piece immediately on the top of the DynaDrive
pump discharge. To remove the one-way check valve, simply unscrew it
from the tee piece.
3.3 Spear point installations
When a pump is installed on a spear, or well point, a check valve fitted immediately
on top of the spear point itself, see figure 3.3. Do not install the check valve at the
pump, or at the top of the well. Do not run the pump without water in it. In these
applications the check valve on the spear must replace the one-way check valve
that’s installed in the tee piece immediately on the top of the DynaDrive pump
discharge. To remove the one-way check valve, simply unscrew from the tee piece.

3.4 Connecting mains scheme or town water supply to either suction,
or discharge of pumps and pressure systems
Most Water Supply Authorities have strict regulations
regarding direct connection of pumps to mains water
supplies. In most cases an isolating tank is required
between mains supply and pump, see figure 3.4. Davey
also recommend this method. Directly applied mains
pressure can exceed pump operating pressure and
damage pump. Davey Water Products Pty Ltd cannot
accept responsibility for loss, or damage resulting from
incorrect, or unauthorized installations.

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 nonreturn valve.
Davey Water Products Pty Ltd cannot accept responsibility for loss or
damage resulting from incorrect, or unauthorised installations.
4. INSTALLATION
Figure 3.5
4.1 Choosing a site
Choose a clean and dry site with a firm base as close to the water source as possible with correct power
supply. Make sure your pump is always connected to an adequate, reliable source of clean water. To protect
your pump from the weather, make sure the pump house is both waterproof, frost free and has adequate
ventilation. The pump should be mounted on a firm base allowing for drainage, to avoid damage to flooring etc.,
that over time may occur from leaking pipe joints or pump seals. Do not mount the pump vertically. Never place
flammable materials on, or near your pump.
The DynaDrive controller comes pre-set to maintain a pressure of 400kPa. However, it is possible to adjust
the pressure set point. Some plumbing authorities impose a pressure limitation on the pressure of water into a
dwelling. Consideration of operating pressures should also be given to appliances within the dwelling. If unsure,
check with local authorities, or a licenced contractor.
4.2 Pipe connections
IMPORTANT: Suction leaks are the largest cause of poor pump performance and are
difcult to detect. Ensure all connections are completely sealed using thread tape only.
DO NOT USE SEALING COMPOUNDS, HEMP, OR PIPE DOPE.
For best performance use P.V.C, or polythene pipe
with a diameter at least the same as the pump’s
inlet. Larger diameter pipe may be used to minimise
Figure 4.1
resistance to flow when pumping for distances longer
than 5m (16’). Use unions at pipe connections to
enable easy removal and servicing.
Use enough “plumbers’ tape” to ensure airtight seal
and hand tighten only, do not screw connections all
the way into suction port, see figure 4.1. To prevent
strain on pump thread always support heavy inlet and
outlet pipes.
Lay suction pipe at a constant gradient to avoid air pockets which may reduce pump efficiency, see figure 4.2.
Avoid installing 90° elbows before the suction inlet of the pump, within a
distance equivalent to 5 x pipe diameter. For example: if using 40mm suction
Figure 4.2
pipe, avoid installing a 90° elbow within 200mm of the pump inlet. This will
assist laminar flow.

4.3 DynaDrive with self-priming and 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.
To help you get the most from this new capability please read this addendum in conjunction with the full
Installation and Operating Manual included with your pump.
Plumbing: Pay special attention to ensuring the suction pipe and associated fittings are airtight. The absence
of a water leak on the suction line may not confirm that the pipe or fittings are airtight.
Should the suction line contain air pockets it can aid the priming process greatly if you can temporarily isolate
the discharge line from the pump and instead use an adjacent tap to allow the pump to discharge water until full
prime is established. Such a facility is also useful for future servicing and troubleshooting should it be required.
Priming: Filling the pump and suction line with water is made much easier by filling from the outlet side and
allowing any trapped air in the pump to evacuate via one of the plugged holes on the pump casing.
• Remove the tee piece on the top of the pump when trying to fill as this contains a check (one-way) valve,
that won’t otherwise allow water to enter the pump casing;
• Remove priming plug and fill casing and suction line (on flooded suction, simply open gate valve to
pump). When full, replace priming plug;
• Ensure outlet nearest to pump is open;
• Ensure all valves in suction line are open;
• Switch on power. All LEDs on the display will flash;
• Refer section “6.1 Start Up Procedure”. A full flow of water should be discharged from the open tap.
4.4 Power connection
IMPORTANT: Long extension leads should be avoided as they often have insufcient
current carrying capacity to run electric motors, hence they can cause substantial
voltage drop and operating problems.
If the electrical fittings in your country make it necessary to remove the plug from the lead fixed to the motor
care should be taken to ensure that the earth conductor green/yellow in the lead is properly connected to a
good earth.
ATTENTION: Ensure that any and all electrical work is only undertaken by an
authorized electrician.
The electrical connections and checks must be made by a qualified electrician and comply with applicable
local standards. Poor installation, or poor power supply may even result in electrical fires!
ATTENTION: Automatic reset thermal overloads will allow the pump to restart without
warning. ALWAYS disconnect the pump motor from the electrical supply before
maintenance or repairs.
NOTE:
• 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.
ATTENTION: We are obliged to inform you that this pump is not to be used by children,
or inrm persons and must not be used as a toy by children. Some insects such as
small ants, nd electrical devices attractive for various reasons. If your pump enclosure
is susceptible to insect infestation you should implement a suitable pest control plan.
6
4.5 The pressure tank
IMPORTANT: Air pressure in pressure tank should be set to 70% of the DynaDrive set
pressure. For example, the default set pressure of DynaDrive is 400kPa. The default air
pressure of the pressure tank for DynaDrive is set to 280kPa (ie 70% of 400kPa). Never
over-charge the tank. Always use air at ambient temperature. Do not overtighten. During
air replenishment the tank should be externally inspected. Any signs of leakage from
the tank may indicate a need for immediate replacement.
If air charge adjustment is required, then follow these procedures:
• Remove the pressure tank completely from pump installation, ensuring to isolate the pressure tank and
release the water pressure from the tank beforehand; or
• Release all water pressure from the pressure tank by switching off the pump at the power point and
opening the closet tap. For above ground supply tanks, it is necessary to close the gate valve between
the supply tank and the pump;
ATTENTION: To prevent personal injury, ensure all water pressure is released from the
pressure system prior to work being performed.
• Leave tap open during air replenishment;
• When all water pressure has been released from the system, check air pressure at air valve on top of
pressure tank. The pre-charge pressure reading should be 70% of set point pressure;
• If necessary, replenish air charge to the correct pressure indicated. Ensure that a tap in outlet piping of
pump is open during replenishment of air pre-charge.

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. These applications include:
• Long suction lines;
• Low flow appliances connected to the pump, such as evaporative air conditioners, slow filling toilet
cisterns, where flows can be a little as 0.5L/min.
Any additional accumulators can be installed downstream of the controller (ie. between the controller and the
first outlet). Where extra draw-off capacity is utilised the additional pressure tank should have a pre-charge 70%
of the system set pressure. For installations requiring flow rates between 125-500mL/min, it is common for the
DynaDrive to run continuously. If this occurs, adjust up the min frequency setting (refer section 7.4) and install a
larger pressure tank. If you have any further concerns, please contact your local Davey representative.
6.6 Decommissioning the DynaDrive
Should it become necessary to decommission the DynaDrive to relocate the it, store it, or conduct some
service maintenance for example:
• Turn off the power to the DynaDrive and unplug it from electrical supply;
• Close any isolation valves on the suction side of the pump;
• Open a tap, or outlet on the delivery side of the pump and discharge excess pressure in the line;
• Close any isolation valves on the delivery side of the pump;
ATTENTION: It is essential that the system is de-pressurized before proceeding.
Failure to do so could result in harm to product &/or user.
• Unscrew the pressure tank from the top of the DynaDrive discharge/delivery outlet. NOTE: depending on
the installation it is possible that water may spill from the pipework and pressure tank. It would be good
practice to prepare for this;
• Unscrew pipework from the DynaDrive discharge/delivery outlet;
• Unscrew pipework from the DynaDrive suction inlet;
• Slide DynaDrive out of location.

7. ADVANCED SETTINGS
7.1 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 7.1 and 7.2.
Figure 7.1
17
Figure 7.2
The normally open switch will allow normal performance. When switch opens circuit, the DynaDrive will
pause. Davey recommends a float switch cable no longer than 3m, when using 2 x 0.25mm2 cable. If the
switch overrides DynaDrive to pause, the DynaDrive display will show a flashing
Fault LED.
The
Automatic LED will also flash on the control display, see figure 7.3.

7.2 Using a remote alarm monitoring
The DynaDrive has available the option to wire in a remote alarm. DynaDrive uses a volt free contact on the
PCB with 1A maximum, see figure 7.6. The contact is compatible with different types of signal types (optical,
acoustics, etc). The contact triggers when fault detected & shown on control display.
7.3 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 200L/min at a pressure of
400kPa. Running two DynaDrive DD90-13 systems in parallel with common discharge would accommodate
this. One DynaDrive would be designated as the MASTER, with the remaining DynaDrive designated as a
SLAVE. Each DynaDrive would require its own pressure transducer. When making changes to settings in the
system, only the MASTER can be adjusted.

On initial startup, the DynaDrive designated as the MASTER will be the first pump to start. The SLAVE
DynaDrive will come on if the first pump is unable to maintain set pressure, even when running at 100%
speed. The next time water is in demand, the SLAVE pump will come on first. This sequence is referred to
as auto-rotate. To wire up the MASTER and SLAVE pump, refer figure 7.6.
20
Figure 7.6
The connection between the DynaDrive controllers requires 2 x 0.25mm2 cable. From one DynaDrive,
use the “COMUNIC” terminal 2. Wire to the “COMUNIC” terminal 2 of the second DynaDrive. To complete
the circuit, from one DynaDrive, use the “COMUNIC” terminal 3. Wire to the “COMUNIC” terminal 3 of the
second DynaDrive. Davey suggests limiting the distance between the pumps to 2m. To set up multiple
DynaDrive to run in a common manifolded system use the following:
• The primary pump is indicated by a solid green
• When secondary pump is unneeded, the
Automatic LED (even in standby);
Automatic LED is flashing green;
• When water is in demand, the first pump to start is the last pump to return to standby;

10. MAINTENANCE
ATTENTION: Automatic resets may allow the pump to restart without warning. Always
disconnect the pump motor from the electrical supply before maintenance or repairs.
When servicing or attending pump and/or controllers, always ensure power is switched
off and lead unplugged. Electrical connections should be serviced only by qualied
persons. If the electrical supply lead of this pressure system is damaged, it must be
replaced by the manufacturer, or an appointed representative. Under no circumstances
should the DynaDrive be disassembled by other than qualied tradespersons. Failure to
observe this warning may expose persons to the possibility of personal injury and may
also result in damage to other property. Do not dismantle spring under pressure.
IMPORTANT: Do not use hydrocarbon based or hydrocarbon propelled sprays around
the electrical components of this pump. During servicing, use only approved, nonpetrochemical based o-ring and gasket lubrication. If unsure, consult your Davey
representative for advice. For protection, DynaDrive monitors input current and will shut
down the pump motor in the event of an over load.
10.1 Periodic pressure tank checks
Depending on the quality of the pumped water, from time to time your tank may require flushing to remove
settled fines such as mud or sand. If sand, or mud can stay in the tank it will accelerate wear on the internal
lining and shorten your tanks life. Safely disconnect the tank from the water supply, discharge all air from the
tank and flush the tank several times with clean water. Once the flushing water is clean, reconnect the tank
and recharge the air as described in the pressure tank section of the installation chapter.
A tank in good order will not leak, but over time due to damage through rough handling, impacts or grit and/
or impurities in the water the tank shell may fail and/or leak. Should the tank leak or show signs of possible
failure the tank should be immediately disconnected and replaced.
