Note
In oil separators with a power of 2.5 m³/h, the non-
return flap is located under the coalescer package in
the oil separator
à
chapter 11.4. When unscrewing
the diffuser, it is possible that in this type of oil
separator the diffuser is not screwed out of the non-
return flap but that the non-return flap is screwed off
the centre tappet in the oil separator. In such case,
the diffuser cannot be pulled out, it remains in the
coalescer package for a while. Continue with the next
step and then pull out the diffuser together with the
perforated round plate and the non-return flap.
Grab the winding end of the coalescer tissue with
17)
pliers and pull it up a bit. Then pull the coalescer
package winding layer per winding layer completely
out of the oil separator.
For oil separators with a power of up to 2.5 m3/h,
18)
take out the perforated round plate und unscrew the
non-return flap unless already done under step 1.12.
For oil separators with a power of 5 m³/h or more,
19)
remove the coalescer cross from below out of the oil
separator.
Clean the inside of the oil separator container.
