10 Dosing System Manual Installation Procedure Securely mount the dosing cabinet, using the fixing brackets supplied, to a suitable location in the vicinity of the fuel transfer pumps. Ensure that the Octamar product drum is secured tightly to the ship build so free movement is not possible. SECURE THE OCTAMAR PRODUCT DRUM Assemble the suction, bleed and discharge hoses using the components as shown in the Equipment Overview (page 5) L/Hr Dosing Unit Page 9 of 12 Issue 1 May 2007

11 Dosing System Manual A. Connect the pump suction side with flexible hose to the suction assembly and drum closer with suction filter (6, 7, 8). Note: The suction hose should be kept as short as possible (2 metres). B. Mount the suction hose with suction assembly, drum-closer and suction filter to the product drum. Note: Ensure that the drum-closer is screwed in completely so that the suction valve and filter will hang 1 cm above the bottom of the drum. Important: The vertical distance (height) between pump unit and bottom of the product drum must not exceed 2 meters (6,5 feet). C. Connect the pump discharges with flexible hoses to the injection assembly and fit the injection nozzle in the main bunkerline. D. Connect the short air bleed hose and place a small container beneath the outlet from the bleed discharge. E. Connect a power supply cable to main switch in box (10). The power supply is 2 phases 115 or 230 or 400 or 440 VAC 50/60 Hz. The power supply is connected directly to the main switch at terminal 1 and 3 and Earth (PE). F. Before powering up the system check if the selection switch (12) is set at right voltage level. Commissioning Procedure The INNOSPEC Marine dosing system is designed to dose into the ship s main bunkerline. The system should be switched ON at start bunkering and switched OFF at end of bunkering of fuel oil. As an alternative the system can dose into the suction filter of the transferpump, for automatic Start/Stop an optional External Start/Stop cabinet has to be installed. Prior to putting the dosage unit into service, the system has to be primed and bled of air. After priming of the unit is completed, setting of the correct chemical dosage rate (flow rate in L/hr) will also be required. You will be informed of the recommended flow rate for your installation prior to commissioning. Please follow the instructions below. A. Make sure all connections are tight. B. Make sure the dosing system is switched ON at main switch (10). C. Make sure the stroke length of the dosage pump is set at 100%. This is the large knob on the pump console. Unscrew the locking screw before turnig the knob. D. Open the air bleed valve (3) 5-75 L/Hr Dosing Unit Page 10 of 12 Issue 1 May 2007

12 Dosing System Manual E. After a few minutes, chemical will discharge from the air bleed hose. F. When there is a constant flow of chemical from the air bleed hose, shut air bleed valve (3). G. Adjust the flow rate with the large knob on the pump. See dosing graph on page 12. The knob can be set from % and is locked tight using a locking screw. Loosen this screw before altering the setting. Tighten the screw after setting of the desired flowrate. The flow rate can be checked with the flow counter (2). H. Switch OFF the power to the dosage unit and close the panel door. Note: Re-priming of the pump may be necessary after changing the product drum and/or if the pump and hoses are disconnected for maintenance or repair.
