2) Close the three water cocks for fresh water.
3) Remove the filler cap of the fresh water cooler by
turning the cap counterclockwise 1/3 of a turn.
4) Pour cooling water slowly into the coolant tank so that air bubbles do not develop. Pour until the
water overflows from the filler port.
If the filler cap is loose, hot steam and water will spout out which may
cause burns.
5) After supplying cooling water, replace the filler cap and tighten it firmly. To reassemble the cap, align
the tabs on the bottom of the cap with the notches on the filler port and turn clockwise 1/3 of a turn.
6) Remove the coolant recovery tank cap and fill with coolant mix to the lower limit. Replace the cap to
the coolant recovery tank.
