How to set up circulation cooling for LT3000 & LT3G

What you will need:

•a bucket (14 liter or larger)

•an aquarium pump (10 - 12mm outlet, at least 1m lift head, around 1800 L/h flow rate, optional adjustable flow)

Instructions:

* Test circulation before actual distillation. Overflow may happen if not properly set up.

1, Set up bucket on the side of condenser; Take the U-tubing out with a screwdriver.

2, Connect pump outlet to a valve with silicon tubing and then connect valve to the circulation inlet of condenser (the bottom connector) with a silicon tubing; Lock the tubing with the clip taken out from the U-tubing.

3, Connect a silicon tubing with the circulation outlet of condenser (the upper connector) and lead the tubing into bucket; Lock the tubing with the clip taken out from the U-tubing.

4, Fill water into bucket and make sure the water level is above the pump;

5, Make sure the bottom of the condenser is higher than the top of bucket;

6, Make sure the back flow silicon tubing end is above water in bucket;

7, Reduce the valve to half open before turn on pump;

8, Make sure water flow steady and water level in the condenser is steady while circulation.

Summary:

1, small is big. A small aquarium pump is good enough.

2, valve is important. Put a ball valve between your pump and condenser to have a good manage.

3, low in, high out. Cooling water is flowing in an opposite direction with your steam.

4, outlet is above. Keep your back flow tube end above the reservoir water. (VERY IMPORTANT! There will be overflow if the outlet is not above water.)

With these 4 factors in consideration you will get a effective circulation cooling condensation.
