
Close drain cocks (Fig. 191 and Fig. 190). To do so, close the caps by
turning them in a clockwise direction and set the rocking lever in a hori-
zontal position. The position of the safety/drainage valve and the drain
cocks is specified in the section 10.6 at the end of this chapter.

Close all water taps.

Close drainage opening on the water tank.

Open the drinking water filler neck on the outside of the vehicle.

Fill the water tank with drinking water. Use a water hose, a water canis-
ter with a funnel or similar for filling.

Set all the water taps to "Hot" and open them. The water pump is turned
on. The warm water pipes are filled with water.

Keep the water taps open until the water flowing out of the water taps
has no bubbles in it. This is the only way to ensure that the boiler is full
of water.

Set all water taps to "Cold" and leave them open. This will fill the cold
water pipes with water.
