5) Check for dirt in resin bowl periodically. If any dirt is seen, replace with new bowl. If removing dirt by
washing the resin bowl, never use washing material other than neutral detergent. Otherwise, the bowl is
damaged.
6) Open and close drain cock by hand. The use of tools can result in damage to the product.
7) Replace the element before 2 years passed from start of use or pressure drop (difference between the
inlet pressure and outlet pressure) reaches 0.1MPa. Or if the element is broken.
8) Check the bowl regularly. Discharge it before drain reaches the element. Refer to 8. Operation and
Adjustment (P20 to 21) for discharging of drain. When a resin bowl or a bowl with level gauge is used,
discharge the drain before the drain reaches the MAX. DRAIN LEVEL.
Caution
1) Check the element periodically and replace it with a new one if necessary. If it is found that outlet
pressure drops or the flow is restricted, check the condition of the element.
2) For the N.O. type auto drain, when there is no pressure, condensate which does not operate the auto
drain mechanism will remain in the bowl. It is recommended to release the residual condensate manually
at the end of the working day.
