START UP PROCEDURE EVAPORATOR

 Check before start-up:

·       Check seawater overboard valve is open

(Manual and remote control valve)

·       Temperature set point is 76 degrees or higher.

·       “Wait in stand by” is shown in the top left part of the control panel.

·       Check if none of the valves are in manual mode (as well on the control panel). Any valves in manual mode are yellow and in failure are red.

Start-up:

·       Open the manual condensate drain.

·       Press the white (start up/operation) button next too the control panel.

 During start-up:

·       When the condensate is completely drained, close the manual condensate drain.

·       If you here heavy steam banging please open de condensate drain valve again. Close the valve again if the banging stops.

·       Check if there are no leaks at pumps or valves.

·        Inform  ECR

·        Open Brine and Ejector overboard valves (manual and ABB)

·        Check if stage drain valves are closed

·        Open the seawater inlet valve on crossover

·        Open seawater suction and discharge valves of seawater pump

·        Open HT inlet and outlet valve

·        Open distilled water valve

·        Open distilled valve to tank

·        Check chemical treatment pump

·        Press auto start

·        When evaporator has started open steam valves if required

·        When on potable water:   -Check open position of valves on tanks

-Start Chlorination system

Evaporator will auto start via the following procedure

·        Seawater pump starts

·        Vacuum breaker valve closes

·        Temperature control valves starts it’s automatic control

·        Ejector pump starts

·        Feed water valve starts to control the feed pressure

·        Chemical dosing pump starts

·        Steam flash drain valve is closed

·        Steam flash pump starts

• Brine pump and level control valve are enabled for control
• The distilled pump and level control valve are enabled for control
• Hot water circ pump is started
• Steam valve starts to regulate
• Salinometer is activated

Check operation of evaporator regularly
