INSTALLATION Place and install the pump on a flat surface on the top of the coolant tank with the pump body being immersed in the coolant shown in Figure 5. Immersion depth of the pump should be at least 25 mm shorter than the depth of the tank and minimum fluid level should exceed lower stage of the pump.
ELECTRICAL CONNECTIONS Centrifugal pumps consist of air-cooled squirrel cage electric motor and pump parts. Pump is connected to the motor perpendicularly via bolts, clutch etc. to operate inside the liquid. A faulty motor or wiring can cause electrical shock that could be fatal, whether direct contact or conducted through standing water.
OPERATION Start up Install the pump according to ‘Installation’ heading in the manual. Switch off the mains and connect the terminals according to ‘Electrical Connections’ heading in the manual. Then close the terminal box. Check installation and electrical connections steps one more time before starting up the pump. Briefly start the motor to check the direction of rotation according to the arrow on the top of the motor (By looking through the fan cover that has to turn counter-clockwise for the AP and BP series pumps.
SERVICING AND MAINTENANCE Observe the general safety precautions for installation, maintenance and repair. Do NOT keep the pump immersed in water if it is not in use for a long period. The pump must be stored in dry and clean place. Check the pump shaft by rotating manually before re-installed. Pump faults, possible causes and solutions are given in the table below.
