1.0 INTRODUCTION
The Vertex PureWaterCooler™ products are a means to produce good-tasting,
safe water without using bottles of stored water. The model PWC 400 described here
is made for counter top use. Its low height permits it to fit under cabinets.
The PWC 400 is made as an “R” or an “F” version. The “R” version
uses reverse osmosis filtration to make good tasting, safe water from city water or
well water. This filter system consists of 5-micron sediment filter, a carbon (GAC)
10-micron filter and a 50-gallon per day RO membrane. The sediment filter removes
dirt, sand, and particles. The carbon filter removes the taste and odor of chlorine and
other pipeline odors. The reverse osmosis membrane removes molecular contami-
nants from the water including hardness minerals. The “R” version requires a water
feed line and a connection to the drain trap to remove the brine water with all the
rejected salts.
The ”F” version has the sediment and carbon filters described above,
but not the RO membrane; therefore, it does not need the drain connection. USE
CAUTION. The “F” version can only be used with softened water or water that has
less than 3.5 grains/gal. hardness (60 mg/l.) to prevent scaling of the heating elements
in the hot tank.
Please read all the instructions in this manual before operating the
PureWaterCooler™ .
2.0 RECEIVING THE COOLER
2.1 Unpacking (All Models)
The PureWaterCooler™ is shipped completely assembled in a double carton.
Remove the top of the box and slide the cooler out. Save the box and packing mate-
rials for use in the event of a return.
2.2 Inspection
Inspect the cooler for obvious shipping damage. Look at the exterior panels to
see if they are dented or damaged.

3.0 Description
3.1 Assembly
TThe PWC 400 assembly drawing is shown in Figure 1. The cooler has two tanks.
There is a main holding water tank with a float switch which controls a solenoid valve on
the feed water line to maintain a constant level of filtered water. This water is cooled in the
holding tank with refrigerant coils. There is a separate hot water tank with an internal heater
coil which is fed by gravity with the cool water from the holding tank. The hot water tank
is directly beneath the cold water tank. The compressor and expansion valve are inside the
cabinet. The controls for the cooler are on the front panel. See Figure 2 for Flow
Schematic.

3.2 Rear View
On the back of the cooler are the main power switches; one for heating and one
for cooling. When heating or cooling is occurring, indicator lights on the front panel
will turn on. The hot temperature is fixed at a nominal 180°F and is controlled with
a thermostat mounted on the outside of the hot tank. The cold temperature can be
adjusted between 36°F and 54°F by a using a screw driver on the slot on the back.
Turn to the left to increase warmth and to the right to increase cold. DO NOT TURN
PAST THE STOPS. There is a cooling fan which exhausts to the rear, so a clearance
of 6-inches from a wall is required.

4.0 Installation
4.1 Positioning the Cooler
There are some precautions to take when positioning and using the
PureWaterCooler™ . See the items in Figure 4a and 4b. In addition, the cooler must
be located near the supply water, and for the “R” version with the reverse osmosis fil-
ter, there must be access to a drain trap to which the reject water from the RO is deliv-
ered. Normally, this can be found in a bathroom, or kitchen sink. Flexible 1/4-inch
plastic tubing may be used for the feed and discharge connections. Normally, these
connections should be within 25-feet of the cooler.
Important Note: Do not cover air intake vent as this will prevent proper chill-
ing from occurring.

4.2 Cooler Water Connections
When received, the water connections on the back have color coded tube sections
with red shipping caps on them. These tube sections must be removed before making
water connections. To remove the tube sections see Figure 8. The 1/4” plastic tubing
should be used for making the Feed Water and Drain connections. If hard copper tubing
is used for the Feed Water and Drain connections, the bulkhead fittings on the cooler must
be changed to metal fittings.
4.3 Feed Water Connections
To connect the feed water, used the supplied self-piercing saddle valve to connect to
the cold water supply line under the sink. Attach the 1/4” tubing to the compression fit-
ting on the side of the valve. Clamp the saddle valve over the copper or plastic feed line
(cold water only). Turn the handle on the valve until the needle stem pierces the tube.
Then retract the needle 1-2 turns to start water flow. See Figure 5.

Figure 4b. Installation Precautions
Do not place cooler next to
oven or dishwasher. Keep
out of direct sunlight
Be sure to use correct power
voltage. Plug power cord
directly into electrical socket

4.4 Drain Connection (Applies to models wit Reverse Osmosis “R-version”)
The black drain line in the back must be hooked to the drain line ahead of the
normal sink water trap.
See Figure 6 below. Place the 2 part drain saddle on the drain pipe
before the drain trap. Allow proper space for the drilling operation. Tighten the sad-
dle bolts evenly on both sides. Using the opening in the drain outlet saddle as a guide,
drill a 1/4” hole in the pipe. Clean any debris out of the drain saddle connection.
Connect the drain line to the cooler using the 1/4” black tubing supplied.

4.5 Quick Connect Fittings
The standard tubing connections on the PureWaterCooler™ are of Quick
Connect 0-ring seal design and manufacture. Use the tubing and follow the instruc-
tions below to make the connections. If you cut the tubing make sure it is a square
cut, fits squarely in the fitting and seals properly.
