Introduction
Congratulations on the purchase of the most advanced water distiller
in the industry! When installed and maintained properly, your
Precision Water Systems 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 Systems 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 Systems 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 effectively removed all of
the soluble inorganic chemicals tested. Removal efficiencies of 99%
or greater were achieved for almost every chemical tested.
All Precision Water Systems Water Distillers are operated and tested
at the factory 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-colour line 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 Systems 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) Water 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 Air 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 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.
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 filled 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
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 you 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.

HYDROLOGICAL CYCLE DIAGRAM
PRECIPITATION
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.
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 rises from the boiling tank leaving almost 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 water bottle
or optional stainless steel storage tank. The charcoal filter (between the
condensing coil and storage container) 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.

UNPACKING DISTILLER BOX DIAGRAM
Unpacking Your Water Distiller
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. Locate the water distiller where a pail, suitable container or drain can be
used for the impurities drain.
4. When unpacking the water distiller and options note the sizes and
consider this when picking an installation location.
5. Locate the water distiller away from a bedroom or other area where the
noise of the water distiller may be undesirable.
6. 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.
Your Water distiller has been shipped in one box. The Water Distiller Box
Components Diagram shown as follows displays all of the parts that will be in
the water distiller box.

Introduction
The purpose of purchasing a water distiller is so you will not have to drink
the unknown 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.
It is important to also keep the water distiller clean so that it can perform
properly and efficiently. Regular cleaning and maintenance will allow the water
distiller to continually provide pure water for a very long time.
Regular Inspection and Cleaning of the Boiling Tank
1. To prevent a build up of scale and contaminants in the boiling tank, it is
recommended that the impurities from the boiling tank be drained after at
least every second distillation process. There may be an off colour line at
the seams of the boiler tank, this is caused by the TIG welding process
used during manufacturing. This is normal and is not a sign of any
concern.
Manual Drain Faucet Location Diagram
2. Refer to the Manual Drain Faucet Location Diagram above. The water
distiller boiling tank can be drained by opening the manual drain faucet
and draining into a suitable floor drain or container.
3. It is important to develop a regular maintenance routine.
25
4. Check for scale build up on the walls of the boiler tank and the heating
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. Always leave boiling tank lid off when ever the
boiling tank is being descaled to reduce fumes travelling through the
cooling coil. Dispose of the first gallon of distilled water as a precaution.

up or more on the heating element, then it is time to clean the boiling tank
using the cleaner descaler. This process is described in the next section.
5. After checking the boiling tank every two weeks for about three months,
you will be able to set up your own schedule as to how often the boiling
tank needs to be cleaned with the cleaner descaler. Distilled water
quantity use and raw water quality will determine your schedule.
Cleaning the Boiling Tank using the Cleaner Descaler
1. Turn all switches off and allow the water distiller to cool down.
2. Remove any loose scale from inside the boiling tank by hand through the
boiler lid. If you are using the optional storage tank, remove the filter
canister and place the sterilization tube onto the coil tube to by pass the
optional storage tank. See Steam Sterilization of Water Distiller Head
in this Maintenance and Cleaning section for more details.
3. Add 3 tablespoons of descaler cleaner to the boiling tank.
4. Fill the boiling tank half full with hot tap water.
5. Mix the cleaning solution well to dissolve the descaler in the water.
6. Fill up the remaining portion of the boiling tank with hot tap water to the
bottom of the water gauge pin. See Boiling Tank Water Gauge Pin
Diagram below.

NOTE: This is performed whenever it is suspected that the water distiller
head or optional storage tank are contaminated.
NOTE: Liquid Sterilization Solutions can be made from Household bleach.
The bleach should be diluted to 100-200 PPM. Products such as Javex,
have 6% Sodium Hypochlorite and should be diluted by placing 3
teaspoons per gallon of water. Always use Chlorine bleach that does not
contain any other ingredients. Alternatively, Hydrogen Peroxide solutions
may be used by placing 3 teaspoons per gallon of water.
Sterilization
Introduction:
Steam Sterilization should be performed on the water distiller boiler and the
optional storage tank before the water distiller is used for the first time or after a
period of storage or non-use. After initial sterilization, the boiler should be steam
sterilized after any maintenance is performed and/or cleaning including the
descaling process. The optional storage tank requires cleaning and steam
sterilization after any maintenance, or if there are any problems with the quality of
the distilled water.
If there is a water quality concern and the system may be contaminated, it is
important to first remove the source of contamination and remove all
contaminated debris and then complete a Liquid Sterilization before a Steam
Sterilization.
Liquid Sterilization of Optional Storage tank
1. It important to first remove the source of contamination and remove all
contaminated debris before liquid sterilization.
2. Drain the water distiller.
3. Add 1/2 gallon of Liquid Sterilizing solution to the water distiller optional
storage tank. If desired, spray some of the solution throughout the inside
of the optional storage tank. Drain a small amount of the sterilizing
solution out of the drain faucet to sterilize the faucet.
4. Wait 20 minutes and drain the sterilizing solution.
5. Rinse the entire inside of the optional storage tank with at least 2 gallons
of distilled water.
6. Repeat the flushing of the optional storage tank with distilled water 2-3
times; continue until no chlorine smell is coming from the faucet.
7. Complete a Steam Sterilization of the boiling and optional storage tanks.
