(As an alternative,several commercial solutions are available and should be used asdirected on the package).iii) Complete filling of the tank with fresh water.iv) Turn on the water pump and slowly open all faucets to release trapped air.v) Allow to stand for 3 hours then drain and flush with fresh potable water.vi) To remove excessive chlorine taste or odor which may remain,prepare a solution of 1 L (1 quart) vinegarto 20 L (5 gallons) water and pour into tank and allow solution to agitate in tank by vehicle motion(several days if possible).vii) Drain tank and flush with fresh potable water.WATER SYSTEMDoc No:MNSA0006 Rev:00Copyright(C) Hanmar Motor Corporation 203 E-3Waste Tank Flushing To flush the waste water tanks:i) Ensure that both tanks are empty.ii) Fill the black water tank by inserting a hose into the toilet and the grey water tank using the sink.iii) Dump both tanks.Both waste water tanks can be flushed using a similar procedure,but rather than filling each tank using thepotable water system,they can be filled by inserting a hose directly into the sink or toilet.POTABLE WATER SYSTEM DRAININGTo completely drain the fresh water system of all water:i) Ensure that the water pump is off and that your vehicle is level.ii) Drain the fresh water tank and the hot and cold fresh water system by removing the threaded cap at thelow point drain.
