Maintenance

Your Riccar  central vacuum unit was designed for use with or without 
disposable bag. Though it is sold with a bag installed, it can easily be 
removed, and the unit modified for use without disposable bags.

1.   Using a flat screwdriver, loosen the clamp collars

 

and remove the rubber coupling from the air 
intake (see page 6, 

figure 4).

2.   Unlatch the two clips and remove the dust  

receptacle (see page 17, 

figure 15).

3.   Remove the bag (see page 17).

4.  Pull the bag adaptor out of the air intake  

(see page 6, 

figure 5).

5.  Put the other adaptor provided in the air intake  

and, making sure that the tabs are aligned  
with the notches, push it in completely  
(figure 20).

6.  Put the rubber coupling back on the air intake 

and tighten the clamp collars using a flat  
screwdriver.

7.  The vacuum unit is now ready for use   

without bag.
