Introduction
Congratulations on the purchase of the most advanced water distiller in the
industry! When installed and maintained properly, your Precision Water Distiller
will provide years of safe, trouble free service. It is important to observe and
follow the safety and maintenance instructions carefully. If you have any
questions or concerns regarding installation or operation of your water distiller,
please contact your dealer.
All 120 VAC Precision Water Distillers are certified to cCSAus Classes 2831-02
and 2831-82 under the Canadian and American Electrical Code.
All water distillers are factory tested with a high voltage ‘Dielectric Strength Test’
and ground fault test prior to shipping.
Precision Water Distillers have been tested by EnviroTest Laboratories which
found the water distillation units to be very effective water treatment systems
capable of removing both harmful pathogens and toxic chemicals from water. In
their study all pathogens were eliminated and none were found in the distilled
water. The water distillation system also eff ectively removed all of the soluble
inorganic chemicals tested. Removal efficiencies of 99% or greater were
achieved for almost every chemical tested.
All Precision Water Distillers are operated and tested at the f a ctory and have
produced distilled water to make sure all components are functioning properly.
All water distillers are wiped clean before shipping, but there may be a water ring
inside the boiling tank. There may also be an off-colou r lin e at the seams of the
storage and boiler tank. This is caused by the TIG welding process used during
manufacturing. This is normal and is not a sign of a problem. Follow all the
Before Initial Water Distiller Operation procedures and you will have pure
water in no time.
Your Precision Water Distiller must be installed according to any Local, State or
Provincial Regulations.

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) Wate r distillers are rated in US gallons, NOT Imperial Gallons.
1 US Gallon = 3.785 litres = 3.785 kg = 8.344 lbs = 0.833 Imp. Gallons
c) Most distilled water holding tanks do not completely drain from the tap.
Ensure this volume of water is included in your calculation by completely
draining the tank or starting your production check with this volume pre filled.
2. Line Voltage
The line voltage at the outlet where the distiller is connected should be checked
with a voltmeter. Line voltage is often much less than expected, especially in
rural areas. Line voltage will also usually drop off dramatically when the daily
commercial load hits the grid from approximately 8 am to 5 pm (often when the
distiller owner is not home and unable to check the line voltage). Line voltage
lower than the distiller rated voltage (on the serial plate) will drastically lower the
water production.
3. Fill Water Temperature
The water used to fill the machine may affect the water production. Cooler fill
water will take more time/energy to heat to the boiling point than hot water.
4. Ambient Ai r Temperature
Water distillers with cooling fans must have sufficient ventilation so that the boiled
steam can be cooled and condensed into distilled water. Restriction of air flow
(such as a closed cupboard) will result in a hot ambient air build up which will not
allow all of the steam to condense into distilled water and some water production
may escape as steam into the atmosphere through the charcoal filter or volatile
gas release vent. This steam loss can also occur in hot summer periods or very
warm climates.
10
5. Heating Element and Boiler Cleanliness
As the water distiller removes impurities so me of the impurities ma y 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.
6. Altitude
The water distiller is rated at the altitude of the manufacturer, which is
approximately 675 m (2214 ft) above sea level. Locations lower than this (closer
to sea level) will have reduced water production due to the higher boiling point of
water at higher atmospheric pressures at lower altitudes.
7. Operating Time, Warm-up Period & Suitable Storage
When checking the water distiller production, the start time should be when the
first few drops of water have entered the charcoal filter canister. Do not start
timing when the distiller turns on as it takes a few minutes for the heating
element, boiler tank and water to heat up. The distiller production rating does
NOT account for this time, but rather the continuous production after the distiller
is up to temperature. Ensure when checking production that you have suitable
water storage for holding the amount of water that will be produced.
8. Manual Fill Boiling Tank Fill Level
When checking the water distillation production on manual fill water distillers, the
amount of water initially poured into the boiling tank will affect the production.
Water should be f illed to the water level pin so that once the water is hot the
maximum amount of water can be distilled without having to heat up and refill.
Under-filling the boiler will decrease the amount of water distilled. Again, the
warm-up time should not be included in the production rate.
11
9. Boiling Tank Heating Element
Once all other factors have been eliminated or checked, have an authorized
service center check that the proper heating element has been installed in your
distiller. Always replace heating elements with the manufacturers supplied
heating elements. Other elements are available from hardware stores, home
repair centers, etc. and look like the same element but they are almost always
not the same. Even if the voltage and wattage are the same, they usually have
different wattage densities and most likely different element sheath materials,
which will result in premature heater burnout in continuous water distillation of
raw water. These heating elements will also likely affect your water distillation
capacity.
10. Combination of the above Factors.
Often a reduced water distiller’s production is a combination of many or all of the
above factors. To ensure maximum production from your water distiller, keep
your water distiller clean and operate it in a well-ventilated area and use room
temperature feed water where possible.
12
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. As the vapour cools it condenses and returns back to the earth as rain or
snow. When rain or snow falls it passes through smog, dust and many other
types of contaminants. These contaminants can be picked up by the falling rain
or snow. Additional contamination of water can occur when it moves through the
ground.

ROCK DEEP PERCOLATION
Hydrological Cycle Diagram
Water Distillers complete their own hydrological cycle. The advantage of
a water distiller over Nature is that the water is produced in a closed environment
free of pollution and contaminants.
Your water distiller uses the boiling tank to heat the feed water to create
steam. The steam rise s from the boiling tank leaving alm ost all of the impurities
behind. The steam enters the condensing coil and is cooled by the fan. As the
steam cools it condenses into pure distilled water and is stored in a stainless
steel storage tank. The charcoal filter between the condensing coil and storage
tank and the volatile gas vent remove any contaminants that boil at lower
temperatures than the boiling point of water. The impurities from the process
remain in the boiling tank and are drained to a suitable drain.
13
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:
1. The water distiller must be plugged directly into a dedicated 120VAC, 15
Amp wall outlet.
2. The water distiller requires sufficient airflow around it to operate. The air
is used to cool the water distiller condensing coil. Locate the water
distiller in an area that will provide enough room for good air flow. Do not
place the water distiller in an enclosed area like a closet.
3. When using the Automatic Feed Water Line Connection to the water
distiller, locate the water distiller close to a household cold water line (after
a water softener if available).
4. Locate the water distiller where a pail or suita ble container can be used
for the impurities drain. Close to a floor drain (sewer) is best especially if
the Automatic Drain Kit is installed.
5. When unpacking the water distiller and options note the sizes and
consider this when picking an installation location.
6. Locate the water distiller away from a bedroom or other area where the
noise of the water distiller may be undesirable.
7. Locate the water distiller close to the kitchen faucet area if the automatic
pump option is being used.
8. Locate the water distiller in an area that is clean and free of dust so the
cooling coils remain clean when the fan is drawing fresh air.
