CNG dispensers TATSUNO EUROPE ‐ Quick User Guide 1. TATSUNO EUROPE FUEL DISPENSERS 1.1. DESCRIPTION OF DISPENSERS All TATSUNO EUROPE dispensers are equipped with high quality technology and a powerful reliable electronic counter of the Czech company TATSUNO EUROPE (hereinafter referred to as TE). All dispensers work in the manual mode – independently, offline – as well as the automated mode, when they are controlled remotely from the kiosk of a fuel station and connected to the cash register (POS) via a data line. All dispensers have body parts (covers, doors, lids, etc.) made of steel painted sheet metal or stainless‐steel sheet metal. Supporting parts of dispenser frames are made of steel painted sheet metal of a thickness 0.8 to 2.5 mm, or stainless‐steel sheet metal. Each dispenser is equipped with an electronic counter with its own diagnostics and displays showing the delivered amount of money in the currency of the country of installation, the amount of fuel in litres or kilograms and the fuel unit price. Displays of the fuel dispensers specified for private use display only the dispensed fuel volume in litres. The standard colour of TATSUNO EUROPE dispensers is white (RAL9016), silver (RAL 9006) and black (RAL9005). The compressed natural gas (CNG) dispenser or dispensing module has a pressure part fitted with certified components made of stainless steel or galvanized steel. The access to the CNG pressure system is fitted with a lever‐closable ball valve, then 25µm input particle filters to protect pressure component and equipment. Gas filling is regulated by valves and secured with check valves. The amount of gas flown through is measured with a mass meter the input of which is fitted with an electronic pressure sensor and mechanical pressure gauge (manometer). All such pressure connections are performed by using stainless or galvanized steel pipes with a high‐quality connection system (two rings). All fixtures and brackets in the pressure section are made of galvanized sheet metal. The output of the pressure module and fixture of delivery hoses is secured with a fixed connection to which a delivery hose is connected which is fitted with ... -

Page 27: Maintenance Of Dispenser Covers
CNG dispensers TATSUNO EUROPE ‐ Quick User Guide inspect the condition of the delivery nozzle, hose and breakaway couplings and decide on repair or replacement of the delivery nozzle, if necessary, according to the type and size of the defect care for external cleanliness of the dispenser, pay special attention to counter window cleanliness 4.1.1. MAINTENANCE OF DISPENSER COVERS Covers of the dispenser (“body parts”) made of painted steel or stainless steel require regular maintenance. Pay special attention to the maintenance of such parts particularly in winter season when, due to the activity of aerosols from chloride agents created from salts used for road maintenance, the paint of unprotected body parts may be permanently damaged, or inter‐crystal corrosion may appear in case of stainless steel covers. Recommended maintenance of painted covers: Wash them with warm water at least twice per month (according to the level of fouling) At least once a month or after each higher surface fouling with fuels – wash them with detergent, thoroughly clean the covers from salt residues, dust and grease (according to the level of fouling) + restore the protective coating on design parts (car cosmetics). Recommended maintenance of stainless covers: Wash them with warm water at least twice per month (according to the level of fouling) At least once a month or after each higher surface fouling with fuels – wash them with warm water, thoroughly clean the covers from salt residues, dust and grease (according to the level of fouling) + restore the protective coating on design parts by using a special agent for stainless sheet metal. RECOMMENDATION We recommend the following protective agents and detergents for stainless sheet metal: ‐ ULTRAPUR – d (producer: MMM‐Group, Germany) ‐ NEOBLANK spray (producer: Chemische Fabrik GmbH, Hamburg, Germany) ‐ ANTOX Surface Care 800 S (producer: Chemetall AG, Switzerland) NOTICE DO NOT WASH STAINLESS COVERS WITH DETERGENTS! 4.1.2. LEVER‐SHUT‐OFF BALL VALVE It is located in the lower part of the pressure module on the inlet pipeline – identification OVI, OVM and OVH on the dispenser diagram – see Appendices 3.2, 3.3 and 3.4. The ball valve is intended for immediate shut off the media flow rate in case of emergency or service of the dispenser.

It is necessary to visually check mechanical wear of the end piece and check its tightness by using a foaming agent at least once a month. The damaged filling end piece must be immediately replaced! Replacement may only be performed by an employee of the authorized service company. We recommend lubricating the fastening mechanism of the end piece neck with silicon oil once per 3 months. This activity may be performed by the fuel station attendant. It is necessary to check conductivity of the breakaway coupling‐hose‐end piece set at least once per 6 months – i.e. resistance between the end of the filling end piece and the central grounding terminal of the dispenser must be lower than 1 MΩ (testing voltage of 500V) in a pressurized operating condition and without pressure. 4.1.12. SAFETY DISCONNECTING COUPLING (BREAKAWAY COUPLING) The safety disconnecting coupling is intended for disconnecting the filling hose in case of its extreme tensile stress. It is fitted with two valves that prevent gas from leaking from both ends of the breakaway coupling after its disconnecting. Breakaway couplings used at OCEAN CNG dispensers allow up to 100 repetitive disconnections and connections. Connection may only be performed by an employee of the authorized service company by using a special tool. It is necessary to visually check mechanical wear of the breakaway coupling and check its tightness by using a foaming agent at least once a month. The damaged breakaway coupling must be immediately replaced! Replacement may only be performed by an employee of the authorized service company.
