1. Pumps intended for use in outdoor fountains garden ponds and similar places must be supplied through a residual current device RCD with a rated residual operating current not exceeding 30mA Where required means for disconnecting the pump from the supply having a contact separation of at least 3mm in all poles must be incorporated in the fixed wiring On 3 phase motors the connecting box shall still meet the IP 44 requirements after the pump has been wired in 480 volt single phase and 415 volt 3 phase motors must be equipped with a contactor and must be wired in by an authorised electrician 3 phase motors can turn in any direction depending on their electrical connection When first connected the power should only be flicked on and off so as to determine the motor rotation If the rotation is not correct as indicated on the pump then any 2 of the 3 power leads should be reversed and the direction rechecked Do not run the motor or pump in the reverse direction as pump damage can occur ELECTRICAL TROUBLE SHOOTING PROCEDURE All Models No electrical power electrical fuse blown pump not plugged in voltage incorrect etc If the motor thermal repeatedly trips there is a fault which should be corrected before major problems occur Simple initial inspection may show cause of jammed or fouled impeller which if not corrected will result in motor burnt out Automatic Reset This automatically resets as the motor cools A BEWARE2.

5. Pump may restart without warning PRESSURE TANK INSTALLATION Pressure tanks must be charged with air before installation The air pressure should be 10 lower than the pressure switch cut in setting of the pump e g pump work ing on 20 40 psi should have a tank air charge of 18 psi Pressure tanks should be installed under cover out of the weather and the air pressure should be regularly checked and maintained PRESSURE TANK MAINTENANCE amp TROUBLE SHOOTING Auto Operation all Models The air charge should be checked at least once a year as tanks gradually lose air which causes pump cycling To check air pressure turn off the electricity to the pump Turn off the gate valve from the water supply Turn on a tap so that the water is drained from the pump Only then measure the air pressure in the tank using a tyre pressure gauge on the valve If the pressure is low recharge using a tyre pump Do not over charge the tank with air as this will cause tank liner damage pressure surge problems and the system to malfunction False readings can be obtained when checking the air pressure unless the tank is completely empty of water If in doubt unscrew or disconnect the tank from the pipe work When the air pressure is correct reinstall the tank open gate valve from the supply tank and turn on the electricity The pump should now operate normally once any air is purged from the lines and pressure switch adjusted accordingly For
