Otherwise there is a risk of a siphoning effect when the system is switched off, leading to components breaking. • The reductant doser can be installed a maximum of 2 metres above the pressure pipe connection on the buffer tank. 02:07 Issue 1.0 en-GB © Scania CV AB 2016, Sweden... -
Page 12: Reductant Tank (Buffer Tank)
See the Workshop Manual. Do not position the reductant tank near exhaust systems or heat sources. The reduct- ant must not be heated to more than 55°C. 02:07 Issue 1.0 en-GB © Scania CV AB 2016, Sweden... -
Page 13: Mounting
Use at least 2 of the brackets and 2 of the holes in each bracket when mounting. In order to be able to remove the reductant tank for maintenance and repair, the brackets must not be welded. 97,25 02:07 Issue 1.0 en-GB © Scania CV AB 2016, Sweden... -

Page 17: Connection Of Coolant
Note: Do not use sea water to cool the exhaust routing valve. Scania recommends using pipes, but it is also possible to use hose. It does not matter which of the connections of the exhaust routing valve (3) are used for coolant intake or coolant return. - Page 18 2.4 bar. The material must be refrigerant- resistant. Note: To ensure sufficient flow, hoses must not have any sharp bends and there must be no spots where they are at risk of being pinched. 02:07 Issue 1.0 en-GB © Scania CV AB 2016, Sweden...
