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. To reduce the risk of electric shock, be certain 

that it is connected only to a properly grounded, grounding-type receptacle. Non-

submersible pump. This pump has not been investigated for use in swimming pool or 

marine areas. To reduce risk of electric shock, pull plug before servicing or cleaning 

this pump. Do not operate this pump with wet hands.

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. 
This appliance is not intended for use by persons (including children) with reduced 

physical, sensory or mental capabilities, or lack of experience and knowledge, unless 

they have been given supervision or instruction concerning use of the appliance by a 

person responsible for their safety. Children should be supervised to ensure that they 

do not play with the appliance. This appliance can be used by children from aged 8 

years and above and persons with reduced physical sensory, mental capabilities, or 

lack of experience and knowledge if they have been given supervision, or instruction 

concerning use of the appliance in a safe way and understand the hazards involved. 

Maximum pressure limited to 64m (210 feet) total head.

IMPORTANT: If the supply cord is damaged, it must be replaced by the manufacturer, 

its service agent, or similarly qualified persons in order to avoid a hazard. Cleaning and 

user maintenance shall not be made by children without supervision. Children shall not 

play with the appliance. 
Outside the United States, pump is to be supplied through a residual current device 

(RCD) having a rated residual operating current not exceeding 30mA. 
In the United States, the National Electrical Code requires GFCI devices intended to 

protect people to interrupt the circuit if the leakage current exceeds a range of 4-6mA 

of current (the trip setting is typically 5mA) within 25ms. GFCI devices which protect 

equipment (not people) are allowed to trip as high as 30mA of current.

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.
