INTRODUCTION FOR M.GP.S

The system is based on the electrolytic principle consisting of copper and aluminium anodes which

are fed with a fixed impressed electrical current from control panel.

The System is designed to give continuous protection with the minimum maintenance againstmarine growth and corrosion caused by marine growth in seawater service line. It will provide

complete protection through the full designated anode life.

Excessive anode current will result in an excessive rate of consumption of the anodes, and then

reducing their life and possibly leaving the water system unprotected if the anodes are worn out.|'q

SYSTE,M PRINCTFTP

The system produces anti-fouling ion using specially alloyed anodes.

There are two Vpes known as the CU(copper) anodes and Al(aluminium) anodes.

CU Anodes are manufactured from copper as major part for system. The copper anode produces

ions which are transported by the seawater and carried into the pipework system to prevent marine

growth.

They release ions during electrolysis as following reactions.

AL Anodes are manufactured from aluminium as supplementary part for system. The slowdissolution of the aluminigm anode produces ions which spread throughout the system and producei

an anti-corrosive layer on the internal surface of sea water cooling lines.

They release ions during electrolysis as following reactions.

INSTRUCTION FOR CONTROL PANEL(KCAFATM TYPE}

I}ISPLAY

The panel contains digital display according to the quantity of anode. Current setting for egoh

\ anode can be easily adjusted by updown button and is shown in the digital display.

The alarm lamp will be oON' when improper current to each anode is set and any failure of system

operation. This alarm can be connected to vessel's alarm system externally.

rDilNG

Two mounting bars with four holes for Ml0 are incorporited on the back plate of rn"$*rl.

,

We recommend a bu1|qh&d mounting in close proximity to the anodes to avoid voltage drop and

cutting cable run costs

MAIN POWER SI.]PPLY CABLE

Run cable from available power source .... via gland to terminal marked Mains In'.

Be sure to connect correct cable to terminal-

STTING I]P

Once the cables have been run and connected, the System is ready to be switched on.

NCIIE - the following procedure can only be carried out with the anodes in seawater. .'-

Switch on the main power.

Set all anodes currents by pressing the buttons unless the readings of digital display

corespond to each current specified in Operation Manual.

3- Switch offuntil ship starts engine(s) up and switch on when sea waterpumps are running.

IN-SERVICE INSTRUCTIONS

DESCRIPTION

Once the System has been installed it will perform two functions : -

l. Eliminate marine growth and reduce the corrosion rate in the seawater service lines. "r1

2. The System uses impressed current sacrificial anodes which last to designed life.

Once in service the anodes will require renewal within designed life.

Refer to instruction of anode renewal as specified separately.

Please ensure a reasonable dispatch time when ordering replacement anodes.

You will require the following : -

ANODE PART No. Q'TY ANODE LOCATION

CU (Copper) KFCU 762 2STRAINER

AL (Aluminium) KFAL762 2

When ordering, inform of maker's reference number specified on the cover sheet of this drawing.

ADJUSTMENTSThe control panel is fully automatic and therefore does not require any adjustments in service.

CHECKINGWb suggest that as a matter of course the Control Panel should be checked every week.

When checking, see that all the digital display ammeters are working, this will determine all is

correct. When the anodes have nearly wasted, the digital display above the corresponding anode

will start to fall. When this happens, turn the anode current knob back to zero and leave it until

the anode renewal.Resetonceagainatseaafter,renewaltocurrentsett ingsgivenpreviously.

WARNING (In case anodes are installed in strainer)

When opening the strainer lid for regular check inside strainer, do not fail to remove all anodes

mounted onto the lid. Lifting up strainer lid without anodes removal and lifting it down gives

serious stress to stud and results in anode breakage.

T]I{EVEN WEARING OF COPPER AFIODE

When anodes are positioned at strainer (filter box) or independent tank, anodes should be regularly

checked for the wear down.

Regarding uneven wearing (particularly wear down in the middle) of copper anode you may sprqy

with tar epoxy paint about 3-4 times except 300mm long from the anode bottom after complete

dry up of copper anode surface, which can help anode dissolved from bottom. Refer to the below

drawing.

IIN-SERVICE ADJUSTMENT AIYD CURRENT SETTINGS

The effectivb working of the system can only be determined by inspection and it is suggested thatif after some 6 months of operation the opportunity to examine a strainea length of pipe or heatcxchanger, presents itsel{, this should be done. g},

h tre event of there being signs of infestation, the current to each anode in this section should behcreased by a ma:rimum of 0.4 amps, but ifno fouling is presentthe current to each anode withintis section may be reduced by a maximum of 0.2 amps.

This routine can be repeated at intervals, the current being adjusted accordingly.
