Description of the operation mechanism of WG250/1000 by each step.
1. Drain of the boiler
Turn on the earth leakage breaker and press POWER key. And after 15 seconds passed, boiler drain
solenoid valve (10) opens for approx. 40 seconds, and cooling water solenoid valve (3) opens for approx. 30
seconds at the same time. Drain of the boiler is performed every 5 hours during distillation.
2. Boiler Water Supply and Distilling Operation
When drain of the boiler is finished, both of raw water supply solenoid valve (4) and boiler water supply
solenoid valve (17) open at the same time in order to supply water to boiler (12). When float switch 1 (8) in
float cylinder (7) detects water level, heater (13) is turned on and distillation starts. With float switch 2 (9),
water supply to the boiler is controlled by opening/closing raw water supply solenoid valve (4) and boiler
