* The automatic air-purge mode operation-purges air by
automatically operating the coolant pump, the coolant
electric three-way valve, and the warm water electric
three-way valve. The coolant pump is automatically
started and stopped repeatedly.
Furthermore, this operation ends automatically, so
there is no need to perform any manual operations.
 Replenish the coolant in the coolant replenishment container before it runs out. (Be careful because if the
coolant replenishment container runs out of water, air will become mixed with the coolant and the air will be
unable to be sufficiently purged.)
Furthermore, check the air discharge state with the air-purge hose (transparent) during the automatic airpurge
operation.
 The normal indication is redisplayed after the automatic air-purge mode operation ends.
(2) Check for remaining air
 Operate the coolant pump, and check for remaining air.
* For instructions on operating or stopping the coolant pump, see "Coolant Pump Replacement Procedures".
If a lot of air is mixed with the coolant, perform the automatic air-purge operation again in accordance with (1).
(3) Replenish the coolant in the reserve tank
 Pour in coolant until it reaches the H level of the reserve tank.
The coolant may overflow during operation if it is over the H level, so do not pour in coolant past the H level.
