Washing of Distiller

Cleaning of condenser
1. Pour the cleaner into the cooling pipe of condenser.
(For preparation of the cleaner, see P. 48)
2. If scale cleaner flows out from the hose connection port, seal it with a rubber stopper. Most scale
will be removed in about four to five hours.
3. After draining the cleaner, wash thoroughly with tap water.
●
Handle scale cleaner with care.
1. Cleaning boiler and heater in shorter period is recommended. When large amount of scale
accumulates, it becomes more difficult to remove, and may lower the volume of distilled water
collection, or cause damage to heater.
2. After cleaning, discharge the cleaner and neutralize it with neutralizer (sodium hydrate, etc.). Use
pH test paper to check whether the liquid has been neutralized. The main component of the scale
cleaner is sulfamic acid (the pH of the water solution is about 1).
3. Store scale cleaner in a sealable container and avoid high temperature and humidity.
4. Always wear protective equipment (gloves, mask, and glasses) when handling the cleaner.
5. If the cleaner comes in contact with any part of human body, wash thoroughly with clean water.
6. Empty container must not be used to contain drinks.
7. Do not release the cleaner into agricultural canals and fields. Doing so may cause withering of
crops.

Installation of boiler
1. Secure boiler with the boiler fixing band so that the connection port of the condenser becomes
horizontal.
Make sure that the gasket is placed inside the cap nut before installing heater into boiler so that
the letter "YK-W-5" turns up ("YK-W-4" for WG1001).
