Installing the vacuum seal
Wrong orders or direction in installation of the
main seal or the sub seal will degrade vacuum
level or accelerate wear of the seal.
Main seal
Spring side
Rotary joint
Sub seal
Teflon seal (optional)
Spring side
(1) Insert the main seal with its side with the spring
visible at the body side through the rotary joint
into the housing.
(2) Put the sub seal over the rotary joint and insert into
the housing taking not to make the seal surface
peel.
※
Be sure to install the rotary joint before
installing the vacuum seal.
※
Take care for the direction of the seal.
※
During washing, take care not to damage the
seal lip and allow it to dry completely after
washing.
※
When you use the vacuum seal for the first
time, it might produce a screeching sound at
the contact with the rotary joint, in which case
lightly apply water or vacuum grease at the
contact surface.
※
The vacuum seal is a consumable part.
