Replacing the Chamber Block

Be sure to unplug the pump unit. 

Replace the diaphragms and the valves with new ones at least once a year to one and a 
half year regularly in order to maintain their initial performance. 

For chamber block replacement, be sure to change both chamber blocks at the same time. 

The rod employs powerful permanent magnets. Therefore, be sure to remove your watch 
and  any  other  precision  machines  before  operation  as  they  may  be  affected  by  the 
strong magnetic force. 

Do not put the actuating rod close to a magnetic card, magnetic disk or other magnetic 
media as the data may be destroyed.
