Operating Parameters . . . .
The ULTIMA 888 unit has been designed to function within specific environmental parameters.
Operation outside of these parameters will nullify any design or manufacturing warranties.
•Feedwater Requirements (for automatic operation):
a. Treated municipal drinking water. If suspended solids are present, a sediment filter
must be used before the mini-softener.
b. Minimum pressure is 20 PSI.
c. Maximum pressure is 100 PSI.
•Ambient air/surface temperatures operating range is 50°-90° F (10°-32° C).
•The ULTIMA 888 is not designed for the outdoor environment nor exposure to direct sunlight.
Suitable Location for Installation . . . .
The location where the ULTIMA 888 is placed in an office or home is very important. Several
factors must be considered:
1. Plumbing. When possible, the unit should be placed near plumbing lines, we recommend all
units should be plumbed in, if possible, to provide the most convenience for the customer.
2. Warm Air/Noise. The ULTIMA 888 system produces two by-products when operating — warm
air, and some low-level noise. When possible, the system should be located away from desks
or work stations. However, the unit may be equipped with an optional timer to control the
operation schedule of the system. With the timer, the unit may be set to operate during non-
office hours or at night.
Note: This will be true only for small offices. Where a large number of people are served by
one unit, the unit may need to be operated on demand and without the timer being engaged.
3. Environmental-Vandalism. In applications where vandalism may be a problem, do not place
the unit in an uncontrolled or hostile environment. However, the following precautions may be
taken to prevent any misfortune.
•Utilize a lock-in cap. Two holes may be drilled into the top cap through which plastic
pins are inserted to prevent unwanted cap removal.
•Place lock-in protectors on fittings to prevent unwanted disconnection of tubing.
•Use torx-type bolts on dispenser attachment brackets.

CAUTION: If you have tilted or laid the cooler
down, let it stand 24 hours in the upright posi-
tion before turning any power on. Otherwise
damage can be caused to the cooling system.
The coolers that are used with the Ultima 888
are a uniques design. Since there is no 5 gallon
bottle with this system, we have chosen to use a
cooler that has a reservoir with a 5 gallon capac-
ity inside the cooler itself. Both the 2 tempera-
ture and the 3 temperature models have a 5
gallon reservoir. The 3 temperature model also
has an internal reservoir for hot water storage as
well.
The hot water tank is located at a lower point on
the cooler than the hot tank faucet. This means
that once the hot tank is filled with water, then it
will always have water in the tank. There are 2
very important points to remember about the hot
tank:
1. Turn the hot tank switch off until the 5 gallon
reservoir is filled, and all of the air in the tank
has been released by opening the hot tank
until water flows.
2. If you are storing coolers that have had
water in them, or could potentially freeze,
drain all of the water out of the cooler. This
must include draining water from the hot
tank with the hot tank drain located on the
back of the cooler.

The internal components of
the cooler are designed to be
removed very easily. This
allows for sterilization and/or
replacement very user-
friendly. The main compont
that you will have to deal with
is the reservior.
Water from the Ultima 888 will pass
through the post filter and enter the
reservoir through a 1/4" fitting on the
top of the reservior. This fitting is
connected to a double-float assem-
bly. Adouble float is used to ensure
long term reliability in the cooler.
If you open the reservoir you will notice a blue baffle at about the
mid-tank level. Water for the room temperature and hot tanks will
be drawn from above the baffle, and the water below the baffle
will be chilled for the cold temperature faucet.

Getting to Know the Minisoft . . . .
The mini-softener is a small water conditioner which utilizes the same cationic exchange resin as
do larger residential and commercial water softeners.
Most water supplies contain calcium and magnesium ions that are caused by water contacting
limestone in the ground. Calcium and magnesium are often referred to as the hardness minerals.
When hard water is heated, these minerals combine with anions and precipitate from the solution
forming scale. This scale increases the maintenance and decreases the life of your product and
thus, the mini-softener is used to eliminate this scale.
Your mini-softener consists of special resin beads which attract certain ions from the water. When
new, the resin in the mini-softener has sodium ions on it. As hard water flows through the exchange
resin, the calcium and magnesium ions are captured by the resin, while sodium ions are released.
Thus, calcium and magnesium ions are exchanged for sodium ions. (Two sodium ions per one
Calcium or Magnesium ion.)
When there is no more room on the resin beads to attract calcium and magnesium, the resin will
become exhausted and will need to be recharged. This is achieved by passing a highly-concen-
trated salt solution through the resin. Whole-house water softeners have automated controls which
regularly rinse the resin with a concentrated brine.
Because of the relatively small volume of water that passes through the ULTIMA unit, the mini-
softener can last for many months before it needs to be recharged. It has been designed to be
replaced in the field and returned to the dealer for servicing. This makes it simple and inexpen-
sive. It can be recharged and returned to service.
Ion exchange resins should not be allowed to dry out. Hence, new mini-softeners come with small
plugs in the inlet and outlet. If a mini-softener is to be exchanged, it is a good idea to loop a length
of tubing from the inlet to the outlet. This keeps the resin wet and reduces spillage of water.
To calculate the number of gallons that can pass through the Mini-Softener use the following calcu-
lation:
2800 Grains Capacity (of the minisoft)
DIVIDED BY
Number of Grains per gallon in the water
EQUALS
Total number of gallons that the minisoft can soften before regeneration

How the ULTIMA 888 Works . . . .
Raw water moves through a mini-softener
(1), which removes hardness scale and
minimizes maintenance of the boiling
chamber, and is then stored in the Feed
Water Tank (2).
Water is drawn from the Feed Water Tank
into the Level Control Housing attached to
the Boiling Tank. The level control housing
maintains the proper level of water in the
boiling tank. During the process of distilla-
tion, the water is boiled in the boiling tank
(3). Steam rises and passes through a
stainless steel condensing coil (4). Afan
(5) cools the steam in the condensing coil
and turns it to high-purity water, free of
virtually all contaminants. The distilled
drinking water is stored in the Distilled
Water Tank (6).
The water then passes through a post filter
(7); either a carbon filter to enhance the
taste and remove any Volatile Organic or
Inorganic Compounds.
Upon demand, the distilled water flows
from the Distilled Water Tank into the
dispenser (8), which has an additional 19
liter (5 gallon) storage system. Hot, cold,
and room temperature water can be
dispensed at your convenience through
three separate faucets (9).

Note: The reservoir of the Aqua Bar dispenser must be
cleaned and disinfected prior to delivery.
1. Remove the Reservoir from the cooler by pulling up. (Figure
18)
2. Plug Hot tank tube (if you are using 3 temperature model)
3. Remove top blue Cover.
4. Mix a solution of one teaspoon of bleach to two gallons of
water. Add to the tank. Note: Rubber gloves should be worn
during the procedure.
5. Wash the inside of the reservoir and the baffle with the
solution. Note: Do not allow the sanitizing solution to remain
in the tank more than five minutes.
6. Drain the solution through the cold water faucet.
7. Rinse the reservoir with two gallons of purified water and
drain the water through the cold water faucet.
8. Remove the plug from the hot tank tube.
9. Completely fill the reservoir with purified water. Drain the
water from the reservoir through all faucets.
10. Ensure all tanks are thoroughly drained.
11. (3 Temp Models) Put sterilizing solution into the hot tank,
then drain out at the hot tank drain.
12. Clean the baffle with a solution of bleach and water. Rinse
thoroughly with purified water and reinstall in the dispenser.

Preparing for Installation . . .
Preparing the MiniSoft
The mini-softener may contain fines or particles of resin which are small enough to pass through
the mini-softener and be carried to the boiling tank in the feed water. These are a result of ship-
ping.
We recommend you rinse the fines from the softener
prior to installing the ULTIMA unit at the customers
location. To rinse the fines:
1. Remove the mini-softener from the packaging
carton and inspect the unit and fittings for possible
shipping damage. Remove the small plugs from
the inlet and outlet fittings. To remove the plugs
from the fittings, follow the instructions on page 6.
2. Cut and connect a piece of 1/4” tubing from the
Feed Water to the top of the mini-softener.
3. Cut and connect a piece of 1/4” tubing from the
base of the mini-softener to the drain.
4. Allow approximately 8 liters (2 gallons) to flow out
of the tubing to a drain until it is clean and free of
resin fines.
5. Remove the piece of tubing from the top of the
mini-softener. Connect tubing from the inlet to the outlet on the minisoft (This will prevent the
minisoft from drying out which can cause damage to the resin). The softener is now ready to
be transported to the installation site.
Preparing the VOC Post Filter
Included with each ULTIMA unit is a V.O.C. post filter. The post filter serves to improve the taste of
the water, and remove any stray volatile contaminants from distillation.
1. Remove the post filter from the package.
2. Connect the speedfit elbow with a piece of 1/4” tubing to a distilled water source.
3. Run Distilled water through the filter until there is a clear stream of water.

Installation of the ULTIMA 888 . . .
Note: In this section, we give instructions for using a saddle tapping valve to connect a waterline
to the Ultima 888 distiller. The saddle-tapping valve and tubing is not included with the Ultima
888, but can be ordered from Pure Water under part #9514 for the saddle-tapping valve, and
9526-25R for 1/4" tubing.
1. Connect the Saddle Tapping Valve to a waterline (Follow instructions with the valve.)
2. Install the 1/4” tubing from the saddle tapping valve or utility hook-up to the top fitting of the
mini-softener.
3. Cut and connect a piece of 1/4” tubing from the bottom fitting on the mini-softener to the Feed
Water Inlet on the ULTIMA unit.
4. Open the saddle tapping valve completely. Check for leaks.
5. Important instructions for 3 temperature coolers:
The cooler must be full of distilled water and all air out of the tanks and lines before turning the
hot tank on. Make sure that the hot tank power switch is in the off position. To access this
switch the bottom front panel on the dispenser must be removed. Figure 22.
Once the dispenser is full of water (24 hours), then the air can be released from the cooler by
holding the faucet open on each of the temperature faucets. For the hot tank, the faucet must
be held for up to 2 minutes for water to flow out of the dis-
penser. Figure 21.
Note: The hot tank Faucet is designed to be child-resist-
ent, to open, squeeze the two parts together and then push
down.
Once water flows out of the hot tank faucet, turn the hot tank
power switch to the ON position.

Quick-Connect Fittings. . . .
We have selected a special type of fitting that is a rapid, simple and secure way to connect tubing.
It is very important that the tube being used has a squarely cut end, and that the tube cross section
is circular and not oval. Cutting with a very sharp blade is recommended.
The fitting consists of:
a. The body.
b. An o-ring to seal against the tubing. (single or double)
c. A collet that grips the tubing and holds it in place.
To Connect:
a. Push the tubing firmly into the fitting.
b. Pull to confirm that it has been secured.
c. Push the tubing firmly into the fitting again.
To Disconnect:
Note: Make sure that the water to the connection is
turned off and that there is no water pressure in the
line or fitting before disconnecting.
a. Push the tubing firmly into the connector.
b. With your fingers or suitable tool, push and hold the
collet against the fitting body.
c. Pull the tubing free.
