�WARNING
O-O-0
Do not use as steam heater.
Repetition of heating and cooling may break BHE, causing steam to blow out.
0
Do not use fluid that causes corrosion of BHE.
Corrosion and erosion can result in the outpouring of fluid from BHE.
Set the warning indication when using BHE for high-temperature, high-pressure, or
dangerous fluid (caustic soda, ammonia, or the like}.
Call for attention to the risk that outpouring of internal fluid may lead to an accident causing
death or serious injury.
To avoid outpouring of internal fluid, observe the following precautions when loosening
the connections of equipments or piping.
• Confirm that operation must be stopped.
• Confirm that BHE internal pressure drops to zero.
• Confirm that BHE surface temperature drops to room temperature.
�CAUTION
心
oo
Water remains inside after submerging test or hydro-pressure test.
Avoid the submerging test or hydro-pressure test in case of operating with the fluid that
must not be allowed to mix with water.
Inevitably, in case of performing the submerging test or hydro-pressure test, after test, dry
sufficiently the inside and outside of BHE.
Use gloves and arm coverings resistant to cutting when handling or operating BHE.
The sharp edges of the plate can cut hands or arms.
Do not touch BHE during or immediately after operation.
Touching BHE with high temperature can result in being burnt or frostbitten.
