FEATURES & BENEFITS  
Designed specifically for wine storage, the WhisperKOOL system is a specialized refrigeration unit  
designed for one purpose only: to maintain the optimal temperature and humidity levels conducive  
to the proper aging of fine wines.  
Humidity Control  
Asthetemperaturebeginstodropwithinthecellar, therelativehumiditywillrise. TheWhisperKOOL  
units do not create humidity. If you live in a dry area of the country, you may need to add humidity  
in the wine cellar. This can be done by introducing a non-heat humidifier or installing a small  
fountain within the cellar. The WhisperKOOL will remove excess humidity from the air and discharge  
it through the drain line hookup on the evaporator unit.  
Quiet Operation  
Years of experience with our self contained cooling units has resulted in a totally new design which  
accounts for a number of environmental conditions unique to wine cellars. We have accounted  
for these variables and incorporated the use of state of the art components which offer quiet and  
sophisticated operations while keeping the basic concept rather simple.  
Condensing Unit Installation, Indoors or Outdoors  
This system offers the option of installing the condensing unit indoors or outdoors. This will  
allow home builders and architects to incorporate this system with the utmost ease with regard to  
installation and space requirements. Note: Exterior installations require a condensing unit  
housing. Please specify the need of this requirement at the time of order.  
Temperature Differential  
The WhisperKOOL split system is designed to operate effectively when the condensing unit (outdoor  
section) is running in an ambient temperature of up to 125 degrees. At this extreme condition,  
the system is able to maintain a 70 degree differential between the Wine Cellar temperature at  
55 degrees and the 125 degree ambient temperature. This is a significant improvement over most  
cooling units designed for wine storage.

System & Features  
The system includes both the evaporator and condensing units packaged in two (2) separate  
containers. An exterior housing is required for outdoor installations and will arrive packed  
separately.  
Evaporator  
Condensing Unit (Shown With Housing)  
Thermostat  
The split system evaporator has been designed to incorporate the Vinothèque PDT ™ series  
thermostat.  
Years of research and testing have gone into the design of the PDT thermostat resulting in advanced  
microprocessor controlled digital technology and pinpoint accuracy. This system incorporates a  
probe designed to measure the liquid temperature in a wine bottle rather than the air temperature  
of the cellar. This results in several distinct advantages:  
• Wineismaintainedataprecise, measured  
temperature.  
• The unit will switch on/off less often,  
extending cooling unit life.  
• The unit will run longer during cycles  
effectively maintaining humidity.  
Additional Features:  
Digital probe - contains a microchip which communicates  
back and forth to the thermostat resulting in accuracy.  
Heavy Duty Circuitry - designed to resist power surges,  
which play havoc on sensitive electrical components.  
Fahrenheit and Celsius readout - for use in the United  
States as well as around the world.

WINE CELLAR / SPACE PREPARATION  
Preparing the Wine Cellar  
The proper design and preparation of the wine cellar is essential in order to maintain the ideal  
temperature and humidity levels. We have created a typical presentation on “How to Build a  
Wine Cellar” which is available for viewing on our web site at www.whisperkool.com. Failure  
to prepare the cellar accordingly will result in the cellar not maintaining proper temperature and  
humidity.

SPLIT SYSTEM INSTALLATION GUIDELINES  
General Installation Guidelines and Instructions  
Vinothèque requires that a certified HVAC technician install and pipe the Split System unit  
modules. Please take a moment to review State and City building codes to insure the safe and  
proper installation of the unit.  
Installing Condensing Unit  
The condensing unit can be mounted inside a utility area of the home or outside utilizing the  
required outdoor condensing unit housing. The system will operate on a 70 degree temperature  
differential. This means that the unit will keep the wine cellar at 55 degrees when the outside  
temperature is 125 degrees and will have the capacity to produce cool air into the cellar as long as  
the ambient temperature does not exceed 125 degrees Fahrenheit. This unit requires a dedicated  
20 amp circuit, non-GFI. Make sure there is a minimum three-foot horizontal clearance in front  
and rear of the unit. The unit may either be hard wired or plug-in depending on local electrical  
codes.  
Internal Condensing Unit Installations. Internal (i.e., inside the building) installations  
require special consideration by having adequate ventilation to dissipate the heat created  
during normal operations. An exhaust port with fan may need to be installed to assure that  
heat is effectively removed from the utility room. A return grille or provision for 500 - 600 cfm  
of cool air to enter the room to replace the exhausted air will accomplish this. Unobstructed  
airflow to and from the unit is a critical factor in the units overall performance. Make sure  
there is a minimum three-foot horizontal clearance in front and rear of the unit. This will  
assure that the unit can move the air around the room in an efficient manner.  
Outdoor Condensing Unit Installations. You must utilize the exterior condensing unit housing  
for outdoor installations. Place the condensing unit on a solid foundation in a location with  
adequate ventilation. There should be three feet for clearance in the front and rear of the  
unit and one foot on each side. The unit should be elevated 18 inches in order to avoid  
any possible flooding or damage by animals, and should be clear of leaves, dirt, and other  
debris.  
Mounting Evaporator Unit  
The evaporator unit should be mounted level and the top of the unit needs to be 6” inches or  
less from the ceiling of the cellar in order to deliver sufficient cooling. As the room cools down,  
warm air will rise to the ceiling, which is then captured into the cooling unit in order to create  
a consistently cool environment. Mounting the unit low in the room will result in a temperature  
variation due to cold air puddling on the floor and the units inability to draw warm air down from  
the ceiling into the unit itself.  
Unobstructed Airflow  
Unobstructed airflow to and from the unit is a critical factor in the units overall performance.

CONDENSING UNIT SKID PREPARATION  
Note: The condensing unit is shipped with a protective foam pad/ block to prevent damaging tubing  
against the condenser coil fins. Please ensure that this pad is removed prior to operation.

Head Pressure Control, Low Ambient Control Switch:  
The switch is used to cycle the condenser fan at low ambient temperature condition. Set the switch  
to 170 psig for cut-in and 70 psig for the differential. Further adjustment may be needed. Verify  
the settings via refrigeration manifold gauge and perform the final adjustments to the readings on  
the gauge manifold.

MOUNTING THE EVAPORATOR UNIT  
1. Disassemble evaporator unit.  
In order to mount the housing to the wall, the internal components will need to be removed and  
reinstalled after mounting the housing. Remove front cover and thermostat by unscrewing four  
captive screws located on each corner of the cover and five at bottom of front cover.  
Note: Thermostat is not plugged into electrical line.  
2. Remove interior assembly.  
The interior assembly is one piece. The assembly should slide out on mounting rails as one  
piece.  
-12-  
3. Identify and remove appropriate knockouts.  
There are knockouts located on the rear panel, right side panel and on top. Remove knockouts for  
the two refrigeration lines and install the two grommets supplied. Remove knockout for electrical  
line. Keep the refrigerant pipes capped to prevent any foreign material from entering, until ready  
to braze.  
4. Mounting housing to wall.  
The unit has six mounting holes on 16 inch wide centers. Utilize all mounting screws to secure  
the housing to the wall (screws not included).  
6”  
-13-  
5. Installing refrigeration lines into evaporator housing.  
With knockouts removed, install grommets supplied. Install housing, mark location and center line  
of holes to be drilled in wall. Slide interior into place, measure the distance from the suction and  
liquid line connection locations to the housing knockout opening. Add that dimension to the length  
of pipe necessary to penetrate the wall for a rear entry plus enough for an elbow connection if the  
pipe is to run up or down the wall on the back side of the unit. A 1/2” 90° long radius elbow will be  
required to connect to a nipple from the suction line and to either a vertical riser through a ceiling  
opening or to extend the pipe through the right side of the housing opening and adjacent wall. Add  
enough length for the pipes to pass through the wall and connect to another fitting.  
Since the piping is parallel to the evaporator coil and the coil is at an angle with the housing, the  
“through the rear” or “side wall pipes” will have to be formed inside the housing to match that  
angle prior to connecting. The 90° elbow on the vertical riser can be adjusted to the proper angle  
to fit the nipple from the elbow to the coil suction line connection. With measurements taken,  
remove the interior assembly and the housing. Drill a 1 1/2” hole for the 1/2” O/D suction pipe plus  
the 1/2” wall thickness cellular insulation and 1/4” liquid pipe. Drill necessary hole for electrical  
wiring.  
Securely cap the piping ends. It is suggested that the pipes be installed from inside the housing;  
the insulation slid over the suction pipe outside the housing; the liquid line taped to the outside  
of the insulation; and the housing placed in position while guiding the pipes through the wall or  
ceiling. Electrical wiring should be pulled through the housing and the housing secured in position  
in accordance with instructions on page 13.  
Pipes from the back  
Pipes from the top  
Pipes from the side  
-14-  
6. Run the electrical line into evaporator on bottom of left side over insulation.  
Wires should be at least 36” long going into the cabinet.  
7. Re-install interior assembly.  
Slide interior assembly back into housing gently. Re-attach using the two screws. Flow a small  
amount of dry nitrogen through the tubing during brazing. This is to displace oxygen and prevent  
the formation of copper oxide. The solenoid should be energized for a free flow without building  
up pressure in the tubing.  
-15-  
8. Attaching refrigeration lines.  
Line up the piping connections. Energize the liquid line solenoid valve, connect Dry Nitrogen, and  
adjust to a slight flow through the tubing, being sure no pressure develops in the piping. Connect  
flare fittings if a flare fitting model, tighten securely, braze other fittings, leak check, evacuate to  
200 microns, charge with R-134 refrigerant, start and check out. Using wire ties, secure tubing as  
low as possible in the evaporator so tubing is not visible through air inlet grille.  
Note: Be sure the tubes do not stick  
out beyond the evaporator opening  
for the front panel.  
-16-  
9. Electrical wires will need to be approximately 36 inches long.  
Attach lines according to schematic shown.

10. Install drain line fitting and drain line.  
Excess moisture in the air will be condensed on the coil fins and captured in the base of the  
evaporator unit. Therefore a drain line will need to be installed to drain the condensate. The  
drain fitting is located in the center bottom of the unit. Attach the supplied drain line and  
route it to a drain. A condensate pump may be required if a drain is not  
readily available.  
Install the drain line fitting to the bottom of the drain pan. The indoor  
drain line must slope downward 1/4” to the foot and have no traps. The  
line cannot run higher than the bottom of the drain pan and should not  
have any kinks or blockage. When installing drain line inside of wall,  
use copper or PVC to protect the drain tube from the elements.

11. Install thermostat.  
Thermostat mounts on the bottom front of the unit. Plug electrical outlet to thermostat and  
mount from underneath with screws supplied.  
12. Install front cover.  
13. Energize unit.  
Note: Thermostat has a 5 minute time delay.

Refrigeration Lines  
A 1/4 inch O/D copper “liquid line” and a ½ inch O/D copper “suction line” connect the two units.  
The refrigerant drier and sight glass shall be installed in that order in direction of refrigerant flow  
in the liquid line between the condensing unit and evaporator. Enclose the suction line in a cellular  
insulation ½” wall thickness Armaflex (brand name) or equal to reduce heat transfer.  
Wiring System  
The compressor is controlled by a “pump down cycle,” therefore, no wiring between the condensing  
unit and evaporator unit is necessary. Wire the system in accordance with local codes and the  
enclosed wiring diagrams (Evaporator wiring on pg 17, schematics below, and on pg 20). The  
evaporator unit requires a standard 15 amp circuit, non-GFI. A dedicated circuit is not mandatory,  
but recommended.

Charging the System (by Certified HVAC technician)  
After all the piping is complete:  
!
Open both of the service valves on the condensing unit. The unit is pressurized with  
Nitrogen and you should hear the gas escaping through the service ports.  
With electrical power connected to the evaporator unit energize the solenoid valve  
(pressurize with dry Nitrogen) to 100psi. Leak test all fittings. Must hold 100psi for 30  
minutes.  
If no leaks are found, leave solenoid valve energized and evacuate the system through both  
the liquid and suction service ports. Using a high vacuum pump, evacuate to 200 microns,  
measuring the vacuum with a digital micron gauge. When evacuation is complete, break  
vacuum and pressurize with liquid R-134A. refrigerant.  
With the electrical power turned on to the condensing unit, and the evaporator unit  
running, slowly feed liquid refrigerant (R134A) into the suction service port. As the  
suction pressure rises to 15 PSIG, the condensing unit will start. Slowly feed refrigerant  
while maintaining a pressure above 10 PSIG to prevent the compressor from short cycling.  
Slowly feed refrigerant with the compressor running until the sight glass is clear of all  
bubbles. Do not exceed 3.5 lbs of refrigerant. Check superheat at evaporator outlet.  
Superheat should be at 10°-12°. Check the compressor crankcase temperature after 30  
minute run time – should be hot 115°to 140°. If cool, superheat is too low. Adjust TXV  
to recommended superheat.  
Allow the system to operate for one hour and then check the refrigerant level in the sight  
glass again. Additional refrigerant may be required as the temperature of the enclosure  
is lowered to approximately 55F or the ambient temperature at the condensing unit rises  
above the temperature at which the unit was initially charged. Depending on temperature,  
the “high side” should be approximately 175 lbs. The ”low side” 28 lbs or more to keep  
the evaporator from icing. It is recommended while charging to use a digital refrigerant  
scale for better accuracy in measuring the amount of charge.  
Maintenance  
The WhisperKOOL system is designed to operate with very little maintenance required. Do check  
the condensing unit and evaporator coils, and vacuum them every three months.

If the breaker remains set, check to see if compressor is  
running and condenser fan turns on.  
After compressor runs a few minutes, check the  
refrigerant “sight glass” in the ¼” copper tubing. Look  
for bubbles.  
If no bubbles are present and compressor is running,  
refrigerant system is running OK.  
If bubbles are present, system is low on refrigerant.  
A CERTIFIED HVAC service technician will have to locate  
and repair any refrigerant leaks, then add refrigerant.  
Condenser fan should come on either immediately on  
compressor start or after sight glass gets warm.  
If not, compressor will trip off on high pressure safety
