Maintenance Method 

Washing of Distiller 

 

Dismounting of Distiller 

1.  Turn "OFF" the earth leakage breaker of the unit. 
2.  Close the tap. 
3.  Check that the boiler is not hot (longer than 30 minutes after the breaker is turned "OFF"), then open 

the front door of the unit, and open the boiler water drain cock. 

4. Disconnect the hose connected to the boiler 

①

 and condenser 

②

.  In disconnecting from the 

distilled water outlet and boiler water supply and drain port, turn the hose band by use of tool and 
displace the engaged portion (serrated portion).  Take care in disconnecting because excessive 
force applied to glass may cause damage.

5.  Disconnect the hole plug at left plate, remove four screws with a screw driver, then remove the left 

plate. 

 

 

6.  Loosen 4 screws on the right of terminal block located at the right top of the body frame with left side 

plate dismounted by use of Phillips screwdriver, and disconnect the heater lead terminal. 
(For WG1000, 8 pieces of screw are used because it has two heaters.)
