Installing the lines
The supports of the suction and discharge lines will be independent of those
of the pump. In the case of plastic lines, ensure tightness of joints and threads
with TEFLON tape alone. Glue or similar products should not be used.
The suction line should have a diameter equal to or greater than that of the
suction mouth of the pump.
The inside of the suction and discharge holes is threaded to a certain depth.
This depth should not be exceeded when screwing on the respective lines.
Only new or clean connectors should be used.
The suction lines should be structured with a slight slant to prevent the
formation of siphons.
Electrical connection
IMPORTANT INFORMATION:
Your Davey pump is Double Insulated to
Water Circuit. If equipotential bonding structure is required, then a
Equipotential Bonding Point is provided. (Please refer to your local statutes
and regulations for AS/NZ 3000 Wiring standards).
The electrical installation should have a multiple separation system with
contact opening of a least 3mm.
The protection of the system will be based on an RCD (I fn = 30 mA).
If outdoor operation is foreseen, the power supply cord should meet EEC
standards (2) or be of type H07 RN-F as per VDE 0250.
Single-phase motors are equipped with built-in thermal protection.
The diagrams in Fig. (1) will allow correct electrical connection.
