4. What to do after replacement of the engine unit
After installing a new engine unit, 1. Please perform the steamed food
operation. When a new engine unit is installed, if the steamed food op-
eration is not carried out, the engine unit will not work normally.
1. Steamed food operation
1) Inject water into the water tank until it reaches water level 2.
2) Press the key “Manual setting”
3) Select “Steamed food”.
4) Set the operation time to 15 minutes.
5) Press the key “Warm-up start”.
6) After the operation comes to an end, repeat the procedure from
step 1) to step 5). (Repeat the 15-minute steamed food opera-
tion two times.)
Note: Do not stop operation halfway. If it is stopped, water will
be left in the tube pump K. So, please conduct forced
drainage in test mode 6.
●After installing the engine unit, please confirm that the
pump tube E is not obstructed where the tube of the en-
gine unit is installed.
[Reason for steamed food operation]
Although the interior of the engine unit has a special
coating to protect its surface, it has a water-repelling
property. Therefore, in case of a new engine unit, water
will not attach to the internal surface of the engine unit
and it is hard to transmit the heat on the engine unit
surface to the water even if the engine unit is heated.
Water vapor cannot be generated and the engine unit
is overheated. The thermistor (engine) detects abnor-
mal temperature and the operation of the engine unit
is stopped.
Hydrophilia of the internal surface of the engine unit
can be improved by performing the steamed food
operation and the thermal transmission will become
normal.
