1. Pre-operation checks should be done on the following:
• Machinery is secure – No damage to mountings, brackets, pipe connections etc.
• Belt drive – In a good condition, belts correctly tensioned and belt guard secure.
• Pipe work and valves – Secure with no leaks.
• Filter units – Check that clean cartridges are fitted to the units
• Water supply and drain – Drain line unrestricted and supply operating correctly.
• Electrical connections – Electrical fittings and cables are secure and undamaged.
• Switches – Electrical breakers and isolator are switched to the on position.
• Emergency switch – Check that the switch is de-activated.
2. Open the sea water supply valve and allow water to flow through the system. If the indicated
pressure drop across the inlet filters exceeds 1 bar the filter cartridge may need to be
changed to maintain optimum performance.
3. Check the inlet water temperature and determine the required temperature rise as outlined in
chapter 3.
4. Press the pump start button. The pump should start and no fault indicator lights should be
illuminated. If any faults are present refer to chapter 5, page 29 for troubleshooting.
5. Enter the required outlet temperature into the controller as the control set point value (SV).
(section 2.2.2 step 4)
6. Turn on the appropriate heater banks as deduced in the procedure outlined in section 3.1
above.
The system should now be operating and all systems functioning correctly. Allow the outlet
temperature to rise to the set point and monitor the control of the process to confirm correct heater
bank selection and temperature output.ipe work and valves – Secure with no leaks.

The supply inlet pressure should be maintained above 3 bar with a sufficient flow rate to
supply the unit with 45 lit/min. The positive displacement pump used generates an output
pressure equivalent to the differential pressure drop through the hose or umbilical while
maintaining a constant flow rate.
