7.4 Cleaning of Head Tank

This section describes the cleaning of the head tank.
(1) Select the <MAINT.> mode.
(2) Open the valves so they are set to drain the tank. For the statuses of each valve in draining,

see Table 6.15.

(3) After the water in the head tank is drained off, open the upper cover and wipe the inside of

the tank with a soft brush, sponge, or the like.

(4) After cleaning is completed, discharge any remaining dirt by supplying tap water or repeat

filling the tank two or three times with "zero water" and then draining it until all of the dirt in

the head tank is discharged with the water.

(5) Finished.

( Good )

( No good )

Align bleeder holes down.

After washing head tank,

align bleeder holes down.

If you align bleeder holes

up then bubbles (froth) may

cause problems.

Drain pipe

NOTE

After washing head tank, be sure to align holes down. If you align bleeder holes up then bubbles

(froth) may cause problems.
