Do not smoke while petrol tank is open and while unit is in operation. • Compressor should be parallel to the floor. Maximum allowable inclination is 5 degrees to ensure effective lubrication and operation.
Page 15: Operation
NAUTILUS MINI If power supply cable is to be replaced, only use cable of the same type. • The compressor needs to be earth effectively. OPERATION All compressor units are tested prior to delivery to the customer, so after correct installation of the unit there should be no problem putting it into operation.
Page 16 NAUTILUS MINI Instruction before start up Pour in suitable compressor oil into the unit. Check the compressor oil level. The level should be around the middle line position (Refer to picture below) Figure 3: Position to check compressor oil Figure 4: Compressor oil positions Check and ensure that the oil level is between maximum and minimum line.
Page 17 NAUTILUS MINI Check the triangle belt’s tension and all the connected parts for signs of loosening. In order to start up and equipment, open up the oil water separator condensate drain valve and air filtration condensate drain valve. (Refer to the figure below) Figure 5: Opening of condensate drain valves Check if the rotational direction of the mechanical belt follows the right direction.
Page 18: Bottle Filling
NAUTILUS MINI BOTTLE FILLING Filling hoses must be in satisfactory condition and threads undamaged. Pay particular attention to damage on the interface from hose fitting to hose. If the rubber is scored, hose must be discarded otherwise water can enter and attack wire gauze casing it to rust and thus endangering pressure tightness Only use accredited air bottle with pressure indication.
Page 19 NAUTILUS MINI Do not disconnect charging hose before purging the pressure in the compressor. How to deal with emergencies during air filling If emergencies happened during the charging process • Power failure • Power cutoff due to overload • Sudden halt of compressor 1.
Page 20: Maintenance And Repair
• The drive belt must be replaced annually or every 1000 working hours of the compressor. • If the tension of the new belt still fails to comply with the necessary requirement, contact Nautilus customer service. - 20 - |...
Page 21 NAUTILUS MINI Changing of air filter • After putting the compressor into service the intake filter must be changed after the first 25 working hours. • The air filter must then be changed every 100 working hours or annually. •...
Page 22 NAUTILUS MINI Instructions to change filtration cartridge 1) For changing of filter cartridge, use customized tools and rotates following the anti-clockwise direction to remove the filter. 2) Use fingers to hook onto the filter cartridge unit. Pull it up to remove and change into the new filter cartridge.
Page 23: Troubleshooting
NAUTILUS MINI Purging condensate Purge once for every 10 – 15 minutes • The compressor oil released from the separator of each stage goes through condensation and form water emulsion. • Periodically after charging (10 – 15 minutes), the condensate drain valve needs to be open.
