Note:
For optimum water cooling, make sure that the cooling water supply meets the
specification given in
connected in parallel. Refer to
recommend use of quick connectors to decrease the risk of water spills during connection
and disconnection. Some pump variants are supplied with quick connector mating
halves. The quick connector mating halves are also available as an accessory kit. Refer to
Accessories
For minimum water consumption, control the cooling water flow to the system.
Setting the cooling water flow rate - Method 1
Before you start, make sure that the electrical power supply to the system is set to off.
To connect the cooling water supply:
1. Use a 3/8 inch BSP male pipe fitting to attach the female quick-release connector
to the cooling water supply hose.
2. Use a 3/8 inch BSP female pipe fitting to attach the male quick-release connector
to the cooling water return hose.
3. Remove the dust caps from the cooling water inlet and outlet.
4. Connect the water return hose to the cooling water outlet. Refer to
Controls/connectors on the rear of the system
5. Install a water flow meter into the water supply line close to the pump and then
connect the water supply hose to the cooling water inlet. Refer to
connectors on the rear of the system
6. Turn on the cooling water supply.
7. Switch on the electrical power to the system. The water valves in the pump cooling
system will automatically open shortly after power up (in 1 minute) for a period of
20 seconds.
8. While the main pump water valves are open, adjust the water flow rate so that it
meets the requirements given in
Note:
All the water valves will close again after 20 seconds and the flow rate displayed by
the water flow meter will decrease. 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.
9. Remove the water flow meter after the water flow rate is set.
10. Do the inspection and leak check of the water hoses, pipelines and connections.
11. Turn off the water supply.
Setting the cooling water flow rate - Method 2
Use the following procedure to connect the cooling water supply and make sure that the
system is receiving the correct water flow rate. Before you start, make sure that the
electrical power supply to the system is switched off:
