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 insufficient
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 infirm persons and must not be used as a toy by children. Some insects such as
small ants, find electrical devices attractive for various reasons. If your pump enclosure
is susceptible to insect infestation you should implement a suitable pest control plan.
