[Cleaning and replacement of the auto drain]
Follow the procedure below for the auto drain maintenance.
Note: Before maintenance
When disassembling the auto drain for cleaning,
replacing parts, etc.,
be sure to completely remove the air
pressure as follows.
Do not disassembly the auto drain
while pressurized.
Exhaust the compressed air from the auto drain < Fig. 1>
Close the inlet of the drain and open the bleed valve gradually.
When compressed air stops coming out, press the flush button
to confirm that compressed air is not left inside.
(A) Disassembly < Fig.2 >
Remove the 4 hexagon socket head cap screws using
an allen key with nominal size 5, and lift up the body.
The entire draining mechanism can be removed.
(B) Cleaning of the interior
1) Hold the body and rinse the lower half of the body (draining mechanism)
with water or lukewarm water with neutral detergent.
Caution!
Never use anything other than neutral detergent.
DO NOT disassemble the draining mechanism.
The mechanism cannot be reused when dissasembled.
When scratches are seen on the main valve (discharge valve) or
it is difficult to clean the dirt off, the main valve needs to be replaced.
Refer to (D) Replacement of the main valve.
2) Wipe the inner surface of the housing with a cloth.
If there is dust stuck to the inside of the housing, leakage can occur
after reassembly.
3) When O-ring is dirty, clean the surface with a soft cloth and check for
gouges and deformation.
Damage or deformation could cause leakage when the product is
reassembled. Replace the O-ring with a new one.
O-ring number: G85 (B)
(C) Reassembly
1) Place the O-ring onto the groove on top of the housing.
Make sure that the O-ring does not come out.
2) Hold the body with the draining mechanism facing downwards. Place the mechanism into the housing so that the
flush button comes to the opposite of the drain inlet. (If the body and housing are not completely engaged, there will
be a gap of approx. 3mm between them. Rotate the body to the right or left)
3) Tighten the 4 hexagon socket head cap screws. (Appropriate tightening torque: 4.9Nm)
Caution!
Ensure there is no gap between the body and the housing before tightening. If the bolt is
tightened with a gap, the parts will be broken.
4) After reassembly, assemble the valve for the drain inlet slowly. Before use ensure that there is no leakage.
