Use of electrical equipment always implies observance of some basic
rules. In particular:
- Do not touch with wet or damp hands or feet.
- Do not operate the pump with bare feet (example: swimming pool
equipment)
- Do not leave the equipment exposed to atmospheric agents
- Do not allow the pump to be used by children or unskilled individuals
without supervision
• In case of breakdown or improper functioning of the pump, switch it
off, but do not touch. Contact Davey for technical assistance for any
necessary repairs and insist on the use of original spares. Failure to
respect this condition could render the pump unsafe to use
• When the Davey AS Series pump is not in use for a substantial period
of time, or use is to be discontinued, disconnect the unit from any power
supply
Before carrying out any service on the pump:
1) Disconnect the mains power from the unit and
2) Relieve all the pressure from the pump head or the injection tube
In the event of possible losses on the hydraulic system of the pump
(breakage of the O-ring, the valves or the hoses), stop the pump
immediately and contact Davey.
1.3 Toxic and/or Dangerous Liquid Dosage
To avoid risk from contact with hazardous liquids or toxic fumes, always
adhere to the notes in this instruction manual and wear protective
clothing (gloves, goggles & overalls).
• Follow the instructions of the dosing liquid manufacturer
• Check the hydraulic part of the pump and use it only if it is in perfect
condition
• Use only the correct materials for the tubing, valves and seals to suit
the liquid to be dosed: where possible shield the tubing with PVC
conduit
• Before disconnecting the metering pump, make sure to flush out and
neutralise the pump head with the proper reagent liquid
