INSPECTION AFTER REMOVAL
●
Place a thread so that it is caught in the valves of the thermostat
and water control valve. Immerse fully in a container filled with
water. Heat while stirring. (The example in the figure shows the
thermostat.)
●
The valve opening temperature is the temperature at which the
valve opens and falls from the thread.
●
Continue heating. Check the full-open lift amount.
NOTE:
The full-open lift amount standard temperature for the water
control valve is the reference value.
●
After checking the full-open lift amount, lower the water temper-
ature and check the valve closing temperature.

INSTALLATION
Install in the reverse order of removal.
Installation of thermostat and water control valve
●
Install the thermostat and water control valve with the whole cir-
cumference of each flange part fit securely inside the rubber
ring. (The example in the figure shows the thermostat.)
●
Install the thermostat with the jiggle-valve facing upwards. (The
position deviation may be within the range of
±
10
°
)
●
Install the water control valve with the up-mark facing up and the
frame center part facing upwards. (The position deviation may
be within the range of
±
10
°
)
Installation of water outlet pipe and heater pipe
First apply a neutral detergent to the O-rings, then quickly insert the insertion parts of the water outlet pipe and
heater pipe into the installation holes.
