Connect and set up the cooling-water

Do not turn on the cooling-water supply until after you complete the electrical installation of the
pump. If you do, condensation may form inside the enclosure and there may be a risk of electric
shock.
Notes: 1. For optimum water-cooling, ensure that your cooling-water supply meets the specification given in
Section 2.6. Ensure water supplies are connected in parallel. Refer to
recommends that quick connectors be used to reduce the risk of water spillage during connection/
disconnection. Some pump variants are supplied with quick connector mating halves, otherwise they are
available as an accessory kit, refer to
2. For minimum water consumption, regulate the cooling-water flow to the system.
Use the following procedure to connect the cooling-water supply and ensure that the system is receiving the correct
water flow rate. Before you start, ensure that the electrical power supply to the system is switched off:
1. Use 3/8 inch BSP male pipe fittings to fit the female quick-release connector to the cooling-water supply hose
and to fit the male quick-release connector to the cooling-water return hose.
2. Remove the dust-caps from the cooling-water inlet and outlet.
3. Connect your water return hose to the cooling-water outlet
water supply line close to the pump and then connect your water supply hose to the cooling-water inlet
(Figure 4, item 15).
4. Turn on the cooling-water supply.
5. Switch on the electrical power to the system. The water valves in the pump cooling system will automatically
open in a pre-determined sequence. 12 Seconds after power is switched on, all the main pump water valves will
open for a period of 20 seconds.
6. Whilst the main pump water valves are open, adjust the water flow rate so that it meets the requirements given
in Table 13. Note that the water valves will all close again after 20 seconds and the flow rate displayed by the
water flow meter will decrease - this is normal. If necessary, cycle the power to the pump to re-open the valves
for a further 20 seconds to continue setting the water flow rate.
7. Once the water flow rate has been set the water flow meter may be removed.
8. Inspect the water hoses, pipelines and connections and check that there are no leaks.
Turn off the water supply while you complete the remainder of the installation procedures.
