To replace repair parts, proceed as follows: Be sure to use our designated genuine parts.

FILTER CLEANING AND REPLACEMENT

(1) When performing cleaning and/or replacement work, be sure to unplug the pump unit ﬁrst.

(2) To remove the ﬁlter cover, put your ﬁngers on one side of the cover and pull it up. (See Fig. 1.)

(3) Remove the ﬁlter from the upper housing, replace it with a new one or clean it. At this time, remove

any dust or foreign matter from the inlet of the ﬁlter cover, and the ﬁlter mounting surface and the

inlet of the ﬁlter. (The inlet is on the top of the upper housing and can be viewed when the ﬁlter is

removed.) If the ﬁlter is dirty, dust it off well. However, if it is heavily soiled, use a neutral detergent

to wash it down, rinse it well with water, and dry it out of the sun before reinstalling.

• When performing replacement work, the pump body may be still hot. Therefore, take care not to get

burnt.

• Clean the ﬁlter every three months. Clogged ﬁlters may result in abnormal heat generation or a

failure of the pump.

• Any dust or foreign matter attached on the pump inlet may cause abnormal noises or pump failure.

(4) Replace the ﬁlter, put the ﬁlter cover back on the upper housing as shown in the ﬁgure below,

align the ﬁtting boss of the upper housing with its counterpart of the ﬁlter cover, then press the ﬁlter

cover downwards from above to ﬁt it in. (See Fig. 2.)

• Take care not to press the ﬁlter cover in its improper position as it may be damaged.

• This pump is of a totally oil-less type. Therefore, never put oil or other liquids into the pump inlet.
