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 contaminants 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 materials 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.

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.

4.1 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 filter, there must be access to a drain trap to which the reject water from the RO is delivered. 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.
