- Maintenance of the air dryer should only be carried out by someone with sufficient knowledge and
experience of air dryers and related equipment.
- Before carrying out maintenance, the important warnings in this manual must be thoroughly read and
understood.
- When replacing or cleaning parts of the air dryer, be sure to remove the compressed air pressure
inside the air dryer to “0”. Never remove the case assembly when the air dryer is operated or air
pressure remains inside. It is extremely dangerous if compressed air pressure remains inside the air
dryer, as parts may come flying off at speed when loosened, or other unexpected accidents.
- This product has parts that become hot during operation and a power supply with high voltage applied.
There is a risk of burns due to heat or electrification by high voltage. Even when operation is shut
down after switching off the air dryer’s illuminated light, there are also charging lines. When working
on the charged sections, be sure to switch off the earth leakage breaker installed before starting work.
- As some parts of the air dryer will remain hot, there is a risk of burns due to residual heat after the
power is switched off. So do not carry out replacement work until the temperature of these parts has
fallen to 50
o
C or less. Wait for about 10 to 15 minutes as a guide.
- When carrying out maintenance work on the auto drain strainer and auto drain, there is a risk of
touching the drain fluid during work. Please follow the safety procedure for operators specified by
customer. (Example: carry out work wearing safety glasses, apron and gloves to prevent discharged
fluid from touching the human body.)
- Use neutral detergent solution to clean parts such as the auto drain strainer and auto drain. Never use
solvent such as thinner.
- When removing the outer casing panel or case assembly of the auto drain, wear gloves to prevent
injuries.
