[Disassembly and cleaning of auto drain]
•
Turn off the switch with lamp.
•
Fully open the valve for pneumatic piping. The bypass valve needs to be opened during this work
when the compressed air is necessary.
1.
Remove the rear panel and check the ball valve is closed.
2.
Press the flush button and release the internal air pressure of the auto drain.
3.
Remove the 4 hexagon socket head bolts using a hexagon wrench key with nominal size 5, and lift
up the body.The whole draining mechanism can be taken out.
4.
Hold the body and immerse the lower part from the body
(draining mechanism) into water or tepid water solution
of neutral detergent, and remove dirt.
Caution Do not use liquids other than neutral
detergent for cleaning.
Also, never disassemble the draining mechanism.
In the worst case, it will be impossible to reuse it.
When the main valve (drain port) is damaged or too dirty
to be cleaned, the whole draining part needs to be
replaced.
5.
Wipe the internal surface of the housing with a cloth.
If there is dust stuck to the inside of the housing, leakage
can occur after reassembly.
∗
If the O ring gets dirty, wipe its surface with a soft cloth, and check there are no flaws and
deformation.If any flaw or deformation is found, they can cause leakage after reassembly, and so the
O-ring should be replaced.
6.
Mount the O-ring in the groove on the top of the housing.Take care not to let the O-ring protrude.
7.
Hold the body with the draining mechanism at the bottom, and mount it to the housing in the direction
where the flush button comes to the opposite side of the inlet of condensate. (If there is a gap of
approx. 3mm between the body and housing when this is done, the drain mechanism may not be
inserted fully. Turn it to the right and left slightly.)
8.
In the condition of step 7, tighten the 4 hexagon socket head bolts.
Appropriate tightening torque: 5Nm
Caution Tighten the bolts without a gap between the body and housing.
If they are forcibly tightened with the gap remaining, the parts can be damaged.
9.
After reassembly is completed, open the valve at the inlet of condensate slowly, and check there is
no leakage before using.
∗
If operation failure occurs even after disassembly and cleaning, replace the whole draining mechanism.
And, shorten the time to the next cleaning.
