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 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 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 Distiller must be installed according to any Local, State or
Provincial Regulations.

Records
Please record all of the important information below to assist you and the service
center in case there is any service work required in the future. All of the
information is required to properly identify your water distiller and will make
servicing much easier. The information is located on the serial plate on the side
of the water distiller head. The Serial Plate Location Diagram below shows a
sample serial plate.

Important Safety Precautions
When using electrical appliances, basic safety precautions should always be
followed including the following:
1. Read all instructions.
2. Do not touch hot surfaces. Use handles or knobs.
3. To protect against electrical shock do not immerse cords or plugs in
water or other liquid.
4. Close supervision is necessary when any appliance is used near
children.
5. Do not allow children to operate this appliance.
6. Unplug from outlet when not is use and before cleaning. Allow to cool
before putting on or taking off parts.
7. Do not operate any appliance with a damaged cord or plug or after the
appliance malfunctions or has been damaged in any manner. Return
appliance to the nearest service facility for examination, repair or
adjustment.
8. The use of accessory attachments not recommended by the appliance
manufacturer may cause injuries.
9. Do not use outdoors.
10.Do not let cord hang over edge of table counter, or touch hot surfaces.
11.Do not place on or near a hot gas or electric burner, or in a heated
oven.
12.Extreme caution must be used when moving an appliance containing
hot water.
13.Always attach plug to appliance first, then plug cord into the wall
outlet. To disconnect, turn any controls to “off”, then remove plug
from wall outlet.
14.This appliance is intended for household use.
15.Save these instructions.
Additional Safety Recommendations
1. Always unplug appliance before servicing.
2. Do not use extension cords with appliance.
3. Ensure there is adequate air space around the appliance to allow the heat
from the appliance to be removed and supply adequate fresh air for
cooling.

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.
