Precision Water Distiller Warranty - The warranty for your Precision Water Distiller covers defects in materials for two (2) years on all parts and labor to the original purchaser. - Stainless Steel parts are covered by a 15 year pro rated warranty. This covers all stainless steel parts such as the boiling and storage tank.
Page 7: Important Safety Precautions
Important Safety Precautions When using electrical appliances, basic safety precautions should always be followed including the following: 1. Read all instructions. Do not touch hot surfaces. Use handles or knobs. To protect against electrical shock do not immerse cords or plugs in water or other liquid.

Page 10: Factors That Will Affect You Water Distiller Production
10 Factors That Will Affect Your Water Distiller Production 1. Water Volume Measurement a) How are you measuring your water? The most accurate is by weight. 1 litre of pure water = 1 kg = 1000 g = 2.2046 lbs b) Water distillers are rated in US gallons, NOT Imperial Gallons.
Page 11 5. Heating Element and Boiler Cleanliness As the water distiller removes impurities some of the impurities may cling to the boiler tank and the heating element. Any of this scale may build up around the heating element and actually insulate it, which will drastically decrease the thermal efficiency of the heating element and require more time/energy to boil water, which will decrease the water production.
Page 12: Understanding How Pure Water Is Produced
Understanding How Pure Water is Produced Your water distiller operates the same as Nature’s hydrological cycle. See the Hydrological Cycle Diagram below. Nature uses the heat of the sun to vaporize surface water and draw it into the atmosphere leaving the impurities behind.
Page 13: Finding A Good Installation Location
Finding a Good Installation Location Before installing your water distiller it is important to find a good location. Following the points listed below will provide the best location for your water distiller: The water distiller must be plugged directly into a dedicated 120VAC, 15 Amp wall outlet.

Page 29: Before Initial Water Distiller Operation
Before Initial Water Distiller Operation Ensure the boiling and storage tank lids are in place and tight. Make sure all control switches are turned off. (See Operation-Controls Section if not sure how to operate). BOILING TANK WATER LEVEL PIN DIAGRAM Ensure the water supply saddle valve is turned fully on by turning counter- clockwise from tight.
Page 30: Normal Operation
Normal Operation Ensure boiling and storage tank lids are in place and tight. Ensure all electrical plugs are properly connected and the water supply valve is turned on. Turn the Power, Fan and Water switches to the ON position. Water will enter the boiling tank, the heating element will energize and the cooling fan will start.
Page 31: Maintenance And Cleaning
Maintenance and Cleaning Introduction The purpose of purchasing a water distiller is so you will not have to drink the impurities in your drinking water. A water distiller effectively removes the impurities and chemicals from your water and returns the taste of pure water so that it is pleasing and healthy to drink for the entire family.
Page 32: Cleaning The Boiling Tank Using Cleaner Descaler
The drain may be operated automatically by installation of the Optional Automatic Electric Drain System. See PWS AED-1 Automatic Electric Drain Kit Installation in the Optional Accessories Section for a diagram of the kit and installation instructions. With the manual drain valve or the Automatic Electric Drain it is important to develop a regular maintenance routine.
Page 33 Add 3 tablespoons of descaler cleaner to the boiling tank. CAUTION: Descaler is a corrosive and poisonous substance. Read safety precautions on the package. As the initial water is added to the descaler in the boiling tank it will produce a bubbling foam substance. Do not overfill the boiling tank.
