Maintenance
Take measures to prevent people from coming into direct contact with
product outlets. Failure to do so may result in burns or other injury from
the discharge of fluids.
CAUTION
Be sure to use only the recommended components when repairing the
product, and NEVER attempt to modify the product in any way. Failure to
observe these precautions may result in damage to the product or burns
or other injury due to malfunction or the discharge of fluids.
CAUTION
Operational Check
A visual inspection of the following items should be done on a daily basis to
determine whether the product is operating properly or has failed. Periodically (at
least biannually) the operation should also be checked by using diagnostic
equipment, such as a stethoscope or thermometer.
If the product should fail, it may cause damage to piping and equipment, resulting in
faulty or low quality products or losses due to steam leakage.
Normal:
Condensate is discharged continuously, together with flash steam,
and the sound of flow can be heard. If there is very little condensate,
there is almost no sound of flow.
Blocked:
(Discharge Impossible)
No condensate is discharged. The product is quiet and makes no
noise, and the surface temperature of the product is low.
Blowing:
Live steam continually flows from the outlet and there is a
continuous metallic sound.
Steam Leakage:
Live steam is discharged through the product outlet together with
condensate, accompanied by a high-pitched sound.
NOTE: JL14-X, JLH14-X and JLH14-B (option) have a minimum required condensate load
requirement to ensure proper sealing.
