How Your Distiller Works
The DP-850 is designed to produce approximately one gallon of high-quality,
pure distilled water every 3.5 hours, or almost seven gallons in a 24-hour period.
The DP-850 is a fully automatic unit. The water level in the boiling tank and stor-
age tank are controlled by individual fl oats and a set of microswitches.
The boiling tank operates on a modifi ed batch approach. Feedwater is automati-
cally added until a high level is reached and this triggers the heating element and
fan to operate. This begins the distillation cycle.
As the unit distills, the water level in the boiling tank falls. When the water level
gets close to the heating element, the low-level microswitch is triggered, causing
feedwater to be added until the high level is reached. If, for some reason, no wa-
ter enters the boiling tank when needed, the fan and heating element will remain
off until the condition is corrected.
Once the storage tank is full of distilled water, the unit will automatically shut
down. The DP-850 will begin distilling again once the water level in the storage
tank drops to approximately 3/4 full. It continues to operate until the storage tank
is full again.
The distilled drinking water is drawn from the storage tank through a faucet on
the front of the tank. An optional demand pump would allow distilled water to be
delivered to a faucet, chilled/hot water dispenser, refrigerator, icemaker or other
locations as desired.
The DP-850 is equipped with a Manual Drain Valve, which allows the residue
from the boiling tank to be drained periodically.
page 6 DP-850 Owners Manual
DP-850 Owners Manual page 7
Note: The use of softened
water is recommended
to minimize scale
build-up in the boiling
tank and drain valve.
Preparing For Installation
Things to consider when installing your DP-850:
•Select an area that will allow the distiller to remain level. Improper leveling
could affect the production rate.
•The distiller must be located in close proximity to a water supply and an
appropriate electrical supply source. The distiller should also be located in
a well ventilated room.
• The DP-850 can be installed on a countertop, table or on the fl oor. If the
DP-850 is installed on the fl oor, it must be at least eighteen inches above
the fl oor. An optional stand may be purchased for this purpose. This is for
several reasons:
1. Easier position to observe, maintain, and repair.
2. Easier to catch the fl ow from the boiling tank when you drain the
residue water.
3. Easier to catch the water from the storage tank.
•Electrical requirements: Isolated 115 VAC, 15 amp circuit (220 VAC, 4.5
amp). Check the electrical rating on the label on the rear of the distiller.
•When connecting the tubing into the quick-connect fi ttings, it is critical
the tubing be inserted fully! The tubing should insert into the fi tting 1/2”
to 3/4”. Failure to do so could cause water damage. We recommend that
prior to inserting the tubing, you mark
the tubing 1/2” from the end being
inserted into the fi tting (see fi gure 1).
After inserting, pull back on the tubing
to verify it is attached securely. This
should ensure the tubing is properly
and fully installed. Also, make sure the
tubing is cut squarely and is free of
rough edges.
• When disconnecting tubing, push in
on the grey collet while pulling on the
tubing until it releases. See fi gure 2.

Installation
CAUTION:The DP-850 weighs approximately 42 lbs. Please use caution when
removing it from the carton to prevent injury.
1. Open the carton.
2. Carefully lift the distiller out of the box so it remains in the upright position.
3. Remove and identify all parts kits as listed on page 4.
4. With a pliers, remove the black plug in the fi tting marked “Distilled Water
Outlet”. If you are not installing a demand pump, insert the grey plug, located
in the parts kit bag, into the fi tting, Pump installation information is discussed
later in this manual.
5. Remove the wire tie inside the boiling tank used to restrain the fl oat during
transit.
Connecting the Incoming Water Line
Notes and Cautions:
Note: The use of softened water for the raw water supply is recommended
to minimize scale build-up in the boiling tank and drain valve.
Note: The DP-850 comes standard with a saddle tapping valve. In some
areas a saddle tapping valve may not be permitted. In such instances, con-
tact your plumber for other water line connection options.
Note: Do not plug the unit into the power source until instructed to do so.
CAUTION: DO NOT use a hot water line for your supply line.
CAUTION: DO NOT turn the saddle tapping valve handle before or
during installation. Be sure the piercing lance does not protrude be-
yond the rubber gasket. Failure to do this may result in damage to the
piercing needle.
To hook-up the Incoming Water Line:
1. Locate the items in the parts kit bag as identifi ed on page 4 as “Incoming
Water Hook-Up”.
2. Turn the household water supply OFF.
3, Remove the blue plug in the fi tting marked “Raw Water Inlet”.
4. Install the 1/4” speedfi t elbow onto the fi tting. Pull to test. See fi gure 4.
5a. For installation on copper pipes:
a. Assemble the saddle tapping
valve on the cold water pipe
so the outlet is in a convenient
direction. See fi gure 3.
b. Tighten the screws evenly so
the brackets are parallel. Tighten
fi rmly, but do not overtighten.
c. Connect the 25’ of 1/4” plastic
tubing to the saddle tapping
valve.
d. Cut the required length of tubing to run from
the saddle tapping valve to the distiller, but
make sure you coil a minimum of 8 feet of tub-
ing behind the distiller to allow it to be moved
away from the wall for cleaning or service.
e. Cut a one foot piece of 1/4” tubing off the end
of the tubing to allow the strainer to be installed.
Note: You may also use a piece of tubing that
was cut in step d.
f. Install the one foot piece of tubing into the elbow
on the Raw Water Inlet. Pull to test. See fi gure 4.
g. Install a 1/4” compression nut onto the tubing
coming from the distiller. See fi gure 5.
h. Install the tubing onto the strainer. See fi gure
8. Make sure the tubing is inserted fully into the
strainer and the fl ow is in the correct direction.
Tighten the nut fi rmly. See fi gure 6.
i. Install a 1/4” compression nut onto the tubing
coming from the saddle tapping valve and con-
nect to the inlet stem of the strainer. Tighten
fi rmly. See fi gure 7.
j. Turn the saddle tapping valve handle clockwise
until you feel it is fi rmly seated. Note: You have
now pierced the water supply line and the valve
is closed.
