WARNING: 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.
The electrical connections and checks must be made by a qualied
electrician and comply with applicable local standards. Poor installation
or poor power supply may even result in electrical res!
WARNING: When servicing or attending pump, always ensure power
is switched off and lead unplugged. Electrical connections should be
serviced only by qualied persons. If the electrical supply lead of this
pressure system is damaged, it must be replaced.
Care should also be taken when servicing or disassembling pump to avoid
possible injury from pressurised water. Unplug pump, relieve pressure by
opening a tap on the discharge side of the pump and allow any hot water in
the pump to cool before attempting to dismantle.
During servicing, use only approved, non-petrochemical based oring and
gasket lubrication. If unsure, consult your Davey Dealer for advice.
WARNING: Do not use hydrocarbon based or hydrocarbon propelled
sprays around the electrical components of this pump.
NOTE: For protection, the Davey
®
pump motor is tted with an automatic
“over temperature” cut-out. Constant tripping of this overload device
indicates a problem e.g. low voltage at pump, excessive ambient
temperature (above 50°C) in pump enclosure.
WARNING: 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.
WARNING: Do not use hydrocarbon based or hydrocarbon propelled sprays
around the electrical components of this pump.
In accordance with AS 3350.2.41 we are obliged to inform you that this
pump is not to be used by children or inrm persons and must not be used
as a toy by children.
