SERIAL NO.
HOW YOUR A-12 WORKS
Your system operates using the combined technology of distillation and activated carbon
filtration. This combined technology is designed to consistently produce high-quality water.
The principle of distillation is quite simple: Raw feed water is taken into the machine where it is
heated and boiled. As the water boils, it kills any micro-organisms. The steam then rises, leaving
behind virtually all the contaminants in the raw water. The cool air removes heat from the steam,
converting it back to water. The water is stored in the storage tank until you are ready to use it.
As a final step, the water passes through an activated carbon post filter to further improve water
purity and overall taste.

GETTING ACQUAINTED WITH YOUR A-12
Figure 1
Your A-12 consists of several major components concealed inside the stainless steel enclosure:
(1) the distiller, where high-quality water is produced; (2) the storage tank, where distilled water
is stored; and (3) the demand pump that distributes distilled water to your desired location.
The distiller contains the following: A boiling tank in which the raw water is boiled; a heating
element; a condensing coil to collect and condense the steam; a fan to cool the steam; and various
electrical controls and safety features (see figure 1). Inside the boiling tank is a float to control the
water level. The storage tank is for distilled water. You can dispense the distilled water through
the faucet provided. This faucet can be placed at a location of your choice. You can also purchase
an optional icemaker hookup kit which will deliver distilled water to your refrigerator’s icemaker
and chilled water dispenser. There is also a float system inside the storage tank to control the
distilled water level.

Page 5
INSTALLING YOUR A-12
Select an area that will allow the Pure Water A-12 to remain level. Improper leveling could affect
the production rate.
Electrical requirements: Isolated 115 to 120 Volt AC, 20 Amp circuit (220 to 240 Volt AC, 10 Amp
on some models). Check the electrical rating on the label on the rear of the distiller.
When connecting the tubing into the quick-connect fittings, it is critical the tubing be inserted
fully! The tubing should insert into the fitting 1/2”-3/4”. Failure to do so could result in the
tubing being released when the line is pressurized with water. This 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 fitting, then pull back on the tubing to verify it is attached securely to ensure the
tubing is properly and fully installed.
The distiller must be located in close proximity to a water supply, floor or other drain and
appropriate electrical supply source. The distiller should also be located in a well-ventilated
room.
CAUTION: The A-12 is rather heavy (66 pounds). Follow these instructions to prevent injury.
a) Carefully remove the A-12 from the carton and remove the parts kits.
Note: You may wish to save the carton and packing materials for future use in the unlikely event
your distiller should require sending to a service center for repair.
A. CONNECTING THE WATERLINE
Note: The use of softened water for the raw water supply is recommended to minimize scale
build-up in the boiling tank.
Note: The A-12 comes standard with a saddle tapping valve. In some jurisdictions a saddle
tapping valve may not be permitted. In such instances, contact your authorized Pure & Secure,
LLC Distributor for other waterline connection options.
CAUTION: DO NOT USE HOT WATER LINE.
CAUTION: DO NOT TURN THE HANDLE BEFORE OR WHILE INSTALLING THE SADDLE
TAPPING VALVE. BE SURE THE PIERCING LANCE DOES NOT PROTRUDE BEYOND THE
RUBBER GASKET.
Locate the parts kit bag identified “Raw Water Hookup Kit”.
b) Turn the household water supply off.
c) Install the saddle tapping valve on the COLD water copper tubing so the outlet is in a
convenient direction.

Page 6
d) Tighten screws evenly. Brackets should be parallel. Tighten firmly. Do not over-tighten.
See figure 2.
e) Connect 1/4” tubing to the saddle tapping valve outlet.
f) Coil a minimum of 8’ (240 cm) of tubing behind the distiller. This will allow the distiller to
be moved away from the wall for cleaning or service.
g) Connect the 1/4” tubing from the distiller to the saddle tapping valve.
h) Turn the saddle tapping valve handle clockwise until you feel it is firmly seated.
Note: You have now pierced the copper tube and the valve is closed.
i) Turn the handle counterclockwise to open the valve. Turn the household water supply on
and check all connections for leaks.
j) Open the saddle tapping valve completely. Check the line for leaks. Tighten where
required.

B. CONNECTING THE BOILING TANK DRAIN LINE
CAUTION: The boiling tank drain line delivers water in excess of 160°F to drain when
actuated. Caution should be used when running this line to ensure safe placement of the
tubing. The end of the tube should be secured so as to prevent movement during the draining
cycle. If young children might to be around the system, it is desirable to run the drain line
through a large diameter piece of CPVC tubing which serves as a “shield”.
Do not connect the drain line directly to a waste water drain, sewer or trap. Always allow an
air gap between the drain line and the wastewater to conform with local codes, and to prevent
the possibility of waste water being forced back into the water distillation system. See figure 3.
If you are draining into plastic pipe, it must be rated CPVC at a minimum to handle the high
temperatures of boiling water. PVC is unacceptable.
Note: This unit is self draining. It must be installed with a proper drain. The location of the
boiling tank drain outlet on the rear of the machine MUST be higher than the household
drain. Failure to install properly could result in the unit draining hot water onto the floor. If
your installation plans do not call for installing with a drain, contact your authorized Pure &
Secure, LLC Distributor immediately. Pure Water cannot be responsible for any damage
resulting from improper installation.
Locate the parts kit bag identified “Drain Waterline Hookup Kit”.
a) Insert one end of the 1/2” high temperature tubing (rigid tubing) into the 1/2” x 1/2”
speedfit elbow. Press in firmly.
b) Insert the elbow into the fitting marked “BOILING TANK DRAIN” (red fitting) on the
rear of the unit (see figure 4). Press in firmly.
c) Run the drain line to the drain of your choice. Secure in place and allow an air gap
between the end of the line and the drain. See figure 3.
d) Slide the 5/8” hose clamp onto the end of the clear, flexible 3/8” tubing. Install the
tubing onto the elbow marked “DRAIN” on the lower rear of the unit (see figure 4).
Tighten the hose clamp securely.
e) Run the clear drain line to the same location as the larger drain line.
Figure 4

Figure 5
C. CONNECTING THE DISTILLED WATERLINE
Locate the parts kit bag identified “Distilled
Waterline Hookup Kit”.
Note: Always use food-grade tubing (as
included with the kit) for plumbing distilled
water. NEVER USE COPPER, as it can dissolve
in distilled water.
a) Insert the 3/8” elbow into the fitting
marked “DISTILLED WATER OUT”
(blue fitting) on the rear of the unit (see
figure 4). Press in firmly.
Note: If you purchased a pressure tank for your
A-12, please take note of installation instructions
included with your Pressure Tank Kit now. If
no pressure tank will be used, please proceed.
b) Cut the required length of 3/8” plastic
tubing to run from the “DISTILLED WATER OUT” elbow on the rear of the unit to the post
filter inlet. Insert one end of the tubing into the “DISTILLED WATER OUT” elbow. Press
in firmly. Insert the other end into the post filter inlet (see figure 6 on page 13). Press in
firmly.
c) Wrap the stem of the faucet with Teflon tape and install the faucet at the desired point of
dispensing as shown in figure 5.
Note: The channel washer and stem nut should be tightened fully and be flush to the
bottom of the sink top to hold the faucet in place.
d) Determine the correct length of 3/8” tubing needed to connect the distiller to the faucet.
Cut and route the tubing to the desired locations.
e) Install the 3/8” speed fitting onto the bottom of the threaded stem of the faucet (with
Teflon tape). Insert the tubing securely into the end of the fitting. Pull to test.
Note: We recommend that you secure the 3/8” saterline to floor joists or other structural
members of the house to preven the tubing from banging during water dispensing.
START-UP
IMPORTANT NOTE: Open the boiling tank lid and remove the wire tie restraining the float.
This is used to prevent damage during shipment.
Note: This system must be fully grounded at all times. The electrical receptacle you use must be a
fully grounded, single phase, AC 115-120 volt (240 volt in some locations), 20 amp minimum
circuit. Where a two-pronged wall receptacle is encountered, it is the personal responsibility and
obligation of the customer to contact a qualified electrician and have it replaced with a properly
grounded three-pronged wall receptacle or have a grounding adaptor properly grounded. If an
extension cord must be used, it should be a 3 wire, 20 amp minimum cord.

Page 9
CAUTION: Do not, under any circumstances, cut or remove the round grounding prong from
the electrical plug.

MAINTENANCE AND CLEANING
The Pure Water A-12 is designed for low maintenance performance. The A-12 has a built-in drain
valve that flushes the contaminants and residue out of the boiling tank after each full tank of
distilled water is produced. This minimizes the build-up of scale in the boiling tank.
A. OVERALL MAINTENANCE REQUIREMENTS
The following guide should be used for the maintenance of your distiller. The timing will vary
according to your local water conditions. It is your responsibility to maintain your equipment.
Without proper maintenance, your A-12 may not produce optimum results. The following times
may be far too long for your particular area, so for the first several times, please keep track of the
average time and adjust the schedule below:
Every month or every 30 gallons*: Clean the boiling tank (see page 13).
Every 3 months: 1) Change the post filter (see page 13).
2) Sterilize (see page 9).
3) Clean the exterior.
* More frequent if feed water is hard.
Cleaning the interior: We recommend the boiling tank be cleaned at least once a month (see page
13). Use Lumen™cleaner (Stock# 6603) and follow the directions provided.
Failure to clean the interior can result in:
1) Contaminant build-up (scale) causing premature failure of the heating element or drain
valve.
2) Reduced purity of the purified water due to ‘splash over’ of contaminants from the boiling
tank.

Page 11
B. CLEANING THE BOILING TANK
CAUTION: UNDER NO CIRCUMSTANCES SHOULD THE CLEANING SOLUTION BE
HEATED AND RUN THROUGH A STEAM STERILIZATION OR DISTILLATION CYCLE.
USE THE FOLLOWING PROCEDURES FOR CLEANING THE A-12:
a) Open the faucet on the sink and remove enough water to restart the unit. This will be
evident because the fan will turn on. Open the top cover and move the function switch to
the CLEAN position. At this time the fan will stop. Carefully feel the boiling tank lid and
check the temperature of the unit. If it is hot, wait at least 30 minutes for the unit to cool.
b) After the unit is cool, remove the boiling tank lid.
c) Add Lumen, following the directions on the package. Mix well, and pour into the boiling
tank.
d) Add additional water using a jar or pitcher until the water level inside the boiling tank is
above the scale line. CAUTION: Do not overfill.
e) Let the solution stand overnight.
f) After the scale has softened, turn the main power switch OFF. This will allow the boiling
tank to drain. Once the boiling tank has drained, turn the main power switch ON and
allow the boiling tank to refill. Turn the power off again, repeat this step several times to
flush the boiling tank of cleaning solution and scale.
g) Return the function switch to the DISTILL position. The unit is now ready for normal
operation.
C. CHANGING THE POST FILTER
a) Turn the main power switch OFF and open the faucet at the sink to bleed the line of
pressure. Close the faucet.
b) Have a bucket available to catch any excess water in the line. Remove the filter by
releasing the fittings on each end. Use care when removing the filter because you will need
to reuse the fittings. Push in on the grey ring in the fitting, while pulling the tube out with
the other hand.
c) Remove the two fittings from the end of the filter (see figure 6). Wrap the threads of each
fitting with new Teflon tape, and install in the new filter cartridge. Tighten securely.
d) Connect the inlet side of the filter to the waterline.
e) Using a bucket, hold the filter outlet over the bucket. Turn the main power switch ON and
allow water to flush the carbon fines out of the new filter. If the storage tank is low,
depress the pump switch and flush the filter.
f) Now that the filter is flushed, reconnect the outlet side of the filter to the waterline.
