A
Loosen A and B from lateral sides of EYF/EYD. Fill up bottom entrance completely
with packing fibers.
B Blend sealing compound and water into solvent-based sealing compound in
accordance with instructions of each brand. After finishing filling of packing fibers,
tighten on A in advanced to avoid solvent-based sealing compound from flowing
over when filling the sealing compound. Add solvent-based sealing compound into
EYF/EYD via B until the amount reaches the place of first threads in B.
C Tighten plug B to complete the work.
Horizontal Work-
A
Loosen A and B from lateral sides of EYF/EYD. Fill up entrances on both sides
completely with sealing compound.
B Blend sealing compound and water into solvent-based sealing compound in
accordance with instructions of each brand. After finishing filling of packing fibers,
pour the solvent-based sealing compound into EYF/EYD via A until the solvent
touches the first place of A.
C Tighten plug A and B back onto EYF/EYD to complete the work.
