* Sizing the Unit to the Room
The specication chart will provide information on the units room size cooling capacity. There are circumstances in which a cellar
design may require a larger unit due to some existing design restrictions. There are several factors such as glass, stone, concrete, etc.
which will seem adequate but do not oer the insulation capacity required to maintain the optimum environment. We recommend
purchasing a unit with a larger capacity to compensate for the design limitations. Under sized cooling units can lead to pre-mature
failure and/or prevent the system from reaching the desired set temperature. As a result they are not covered under warranty.

What is the WhisperKOOL Cooling System?
The WhisperKOOL cooling system is a specialized refrigeration system designed to maintain the optimal temperature
and humidity levels conducive to the proper storage and aging of ne wines. This system produces minimal in-cellar
noise and has the most lenient exhaust requirements.
How Does the Cooling System Work?
Similar to the air conditioning systems used for homes, the evaporator and condensing units are installed in separate
locations and are connected by a refrigerant line set. The evaporator portion is commonly installed in an attic or
mechanical room, with the condensing unit located either outside or in a remote indoor location that is ventilated. An
exterior housing is required for outdoor condensing unit installations.
Temperature Setting
The WhisperKOOL system can be set at any temperature within the acceptable wine-aging range of 50°F to 70°F.

WARNING
Be sure to build your wine cellar to be well insulated and to have a well sealed vapor barrier.
The quality of insulation and seal of your build will be a factor in maintaining the ideal
temperature and humidity of your wine cellar. It will also determine how often your unit
will have to run. Failing to properly insulate and seal your wine cellar may reduce the units
capacity to cool the cellar and may reduce the cooling system’s overall life span.
Allowing your system to operate in high ambient temperatures for extended periods of time will
greatly decrease the life of your system and void your warranty. The cooler the temperature of the
air entering the condenser coil, the more cooling capacity the system has. The lower the heat gain
through a common wall, the lower the consumption of electricity.
Note: If you are unsure about having adequate ventilation in your install location, please
contact us to assess your specic installation at support@whisperkool.com or 1-800-343-9463.
*Well insulated and sealed wine cellar is required!

DRAIN LINE
Condensation Drain Line
A condensation drain line is used to remove excess condensation from the unit to a proper discharge location. It is
important that the drain line tube is properly connected.
Failure to use the condensation drain line tube will void the warranty on the unit.
Drain Line
The Quantum evaporator accommodates standard 3/4” CPVC Tubing. It is imperative to use proper primer and glue
to ensure there is a water tight seal between the tubing being connected and the fitting on the unit.
A P-trap is required to ensure proper drainage of the condensation. Below is a detailed diagram of
how the P-trap should be constructed to allow for easy cleaning.
NOTE: The thread tting is identied in this drawing to
ensure cleaning the drain is as easy as possible.
NOTE: Use a soft tube cleaning brush to clean out the drain
line. Failure to use a soft brush could cause damage
to the drip tray of the unit and void the warranty.
Float Switch
The evaporator unit comes equipped with a float switch to monitor the level of condensation in the drip tray. If the
drain line gets obstructed the float switch will stop the operation of the unit and send a BAL alarm to the display. The
unit will not run until this fault is corrected.
Connecting the Drain Line
Apply CPVC primer and glue to the female tting coming from the
unit and the CPVC Tube that will be connected.
TO
UNIT
Insert the a piece of CPVC tubing into the Female Fitting.
Route Additional CPVC tubing to an appropriate discharge location.
(Tubing is not provided).
WRONG: Drain line is under water.
To prevent mold from growing, allow the
drain line to hang above the water line.

Page 16
LIQUID MEASURING THERMOSTAT SYSTEM
The WhisperKOOL Series cooling units come equipped with a liquid temperature measuring thermostat.
This incorporates the following advantages:
Self-Calibrating Bottle Probe
The bottle probe contains a sensor chip, which communicates back and forth with the thermostat. This results in a
consistent temperature setting and accuracy.
1. Wine should be kept at a very precise, controlled temperature and humidity.
2. By measuring the liquid temperature rather than air, the unit will operate 75–80% of the time.
Setting Up The Bottle Probe:
1. Locate an empty wine bottle.
2. Fill ¾ full with room temperature tap water.
3. Place bottle probe securely into bottle as seen in Figure 1.
4. Place bottle with probe on a level surface in you wine cellar.
5. To assure a consistent temperature, place bottle probe approximately 3 feet
away from the air output and not in the flow of the air.
It is recommended that the bottle be placed in a central location of your
wine cellar. Avoid pulling too much on the probe cord. It may become
disconnected resulting in limited functionality of the unit.
Note: The thermostat can be set between 50–67°F.
Remember: The WhisperKOOL unit operates based on the temperature of the water.
Do not be misled by thermostats reading air temperature. The air temperature
in the cellar will be cooler than the liquid temperature of the wine while it is
reaching optimum balanced temperature.

PREPARING THE CONDENSING UNIT
Electrical Needs
The SS12000 Condensing Unit requires a dedicated 230V single phase, 20 amp circuit.
The SS9000 Condensing Unit comes with a plug for a Tandem 230/208V, 15 amp receptacle.
The unit draws a large inrush current for about 1 second, the instant the compressor starts. With a dedicated circuit and circuit
breaker, the Condensing Unit will have sucient power for eective operation. (The compressor is controlled by a low-pressure
switch mounted on the Condensing Unit. This feature eliminates the need for wiring between the Evaporator Unit (Fan Coil Unit)
and the Condensing Unit).
• Ensure the voltage supplied matches the rating specied on the unit spec. label.
• Provide a non GFI dedicated circuit and an appropriate outlet for the Evaporator Unit’s (Fan Coil Unit) power cord.
• Provide a dedicated circuit and circuit breaker for the Condensing Unit.
• Provide a weatherproof disconnect for Condensing Units located outside.
As with all sensitive electrical equipment, damage may be caused in the event of power surges and spikes. WhisperKOOL
recommends plugging the unit into a surge protector, or power conditioner, in order to protect your system. As outlined in our
Terms & Conditions, power surges and spikes are not covered under warranty.
WE RECOMMEND THAT YOU DO NOT USE A GROUND FAULT INTERRUPTER (GFI) WITH THIS PRODUCT.
In case the system should lose power, check the home/main circuit breaker. If the system does not respond properly, refer to the
Troubleshooting Guide on page 30.
For the equipment warranty to be valid, WhisperKOOL requires that the installation is performed by a certied HVAC-R technician
(NATE certied technician is recommended) per the specications outlined in this Owner’s Manual. The technician shall be
required to be equipped with the proper tools of the trade including: R-404a, brazing equipment, dry nitrogen, an accurate
manifold gauge set (digital preferred), plus a 4 valve manifold set for evacuation, digital micron gauge, digital scale, deep vacuum
pump and accurate digital thermometers. Without the proper equipment, a professional job cannot be accomplished. Evidence of
the certied tech’s NATE# or other certication is required.

PREPARING THE CONDENSING UNIT CONTINUED
Installing the Condensing Unit
The Condensing Unit can be installed inside a well ventilated area of the home, but it is typically installed outside. Exterior
applications will require the use of a protective housing, and the amount of sun exposure should be considered when selecting
the placement of the Condensing Unit. Make sure there is a minimum 3 ft. horizontal clearance in the front and rear of the unit.
Check that proper power is supplied.
Set the Condensing Unit level and with proper clearances in accordance with the instructions, as designated on name plate,
proper electric disconnect, and fuse protection connected but not turned on, and is ready for piping connections.
Inside Condensing Unit Installations:
Inside installations require special consideration, as there must be adequate ventilation to remove the heat created
during normal operations. An exhaust port with fan may need to be installed to ensure that heat is eectively removed
from the utility room. A return grille or provisions for 800 - 1000 cfm of cool air to enter the room to replace the
exhausted air will accomplish this. Unobstructed airow to and from the unit is a critical factor in the units overall
performance. Make sure there is a minimum 3 ft. horizontal clearance in the front and rear of the Condensing Unit and at
least 1 ft. on each side. This will assure that the unit can move the air around the room in an ecient 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 3 ft. of clearance in the front and rear of the unit and
1 ft. on each side. The unit should be elevated 18” in order to avoid any possible ooding or damage by animals, and
should be clear of leaves, dirt, and other debris.
Fan Cycling Switch:
These switches are used to cycle the condenser fan at low ambient temperature conditions. (The switch will turn the fan o when
the pressure drops below 210 psi and will turn the fan on when the pressure exceeds 275 psi.
Refrigeration Lines:
A 1/4 inch O/D copper liquid line is required.
Suction Line Size Chart
Model
Quantum SS9000
& SS12000
The refrigerant drier and the sight glass shall be installed (in that order) in the direction of the refrigerant ow in the liquid line
between the Condensing Unit and Evaporator Unit (Fan Coil Unit). Enclose the suction line in a cellular insulation ½” wall thickness
Armaex (brand name) or equivalent to reduce heat transfer and prevent the suction line from sweating.
High Pressure Switch:
The unit is equipped with a high pressure switch to protect the system in the event of condenser fan failure or other major failure.
the switch will open and kill power to the compressor and condenser fan motor if the pressure exceeds 425 psi. The switch will
reset once the pressure falls back below 300 psi.

When installing/routing the line set, cap both ends of each tube to prevent material or debris from entering the tubing.
Prior to connecting the piping, loosely connect the refrigerant gauges to the service ports of the suction and liquid line service
valves. Purge the charging hoses with dry nitrogen and tighten the hose connections. Remove the service valve caps and turn
the valve stem clockwise (half of a complete turn) in order to unseat the valve and open the service port. The valve comes in a
back seated position from the factory. Keep the piping port sealed until ready to connect to the vacuum pump.
Cleanliness is of the utmost importance. All horizontal suction piping should be pitched toward the Condensing Unit a 1/2” for
every 10’ of pipe. During any brazing procedure, dry nitrogen should be purged through the tting at a slow rate to prevent
formation of highly abrasive copper oxide. Make sure there are no obstructions to the ow which would cause pressure build up
and the brazed ttings to leak. After leak testing and conrming there are no leaks, insulate suction line with 1/2” wall thickness
Armaex or equivalent insulation. Seal all seems using Armaex 520 Foam Insulation Adhesive or equivalent. Wrap each seam
using line set tape.
Liquid Line Piping Procedure
It is required to use a 1/4” OD copper tube liquid line. When making connections keep the ends sealed until ready to t the tube.
First connect the supplied refrigerant drier closest to the liquid service valve (king valve) on the receiver. Downstream, connect
the moisture indicating sight glass in an easily visible location. Run the tubing to the Evaporator Unit (Fan Coil Unit) location
and t to the liquid line stub from the Evaporator Unit (Fan Coil Unit). Energize the Evaporator Unit (Fan Coil Unit) and set the
temperature controller to call for cooling. This will activate the liquid line solenoid valve. Uncap the suction pipe to prevent
obstructed nitrogen ow. Open the nitrogen to allow a slow ow and braze the liquid line tting. Do not shut o the nitrogen
and power until the suction line is brazed.
Suction Piping Procedure
Slide Aramaex insulation over the tubing for the entire length of the tube and keep the end of the tube sealed during this
procedure. Keep the tubing sealed while running the connection points and t the suction tube to the Evaporator Unit (Fan
Coil Unit) outlet connection. Install a Schrader Type Access Valve at the outlet of the Evaporator Unit (Fan Coil Unit) to allow for
superheat checking. If there are brazed ttings along the length of the tube, apply the insulation after leak testing.
After All Piping Ran and Ready for the Brazing Process
Energize the Evaporator Unit (Fan Coil Unit) and set the temperature controller to call for cooling. Open the liquid line service
valve and bleed the nitrogen through both the liquid and suction line. Loosen the suction gauge hose to relieve pressure during
the brazing process. Braze the connections and cool them o quickly.
Leak Testing
Using dry nitrogen, pressurize the system to 200 psi. With pressure at 200 psi, check for leaks with a refrigerant leak detector and/
or soap bubbles. Check to see if there is a noticeable pressure drop. If so, locate and x leak. Conrm the pressure holds at 200
psi for 30 minutes. If not, check again for leaks and repair, then perform another leak test. When it is conrmed that there are no
leaks, release the nitrogen pressure and leave the solenoid valve energized.

INSTALLING THE CONDENSING UNIT
Evacuation
Connect the evacuation type 4 valve gauge manifold to the high and low-pressure service valve ports on the Condensing Unit
with the valve stems mid-seated as when leak testing. Install service caps on the valves and tighten them. Energize the liquid
line solenoid valve (make sure there is fresh oil in the vacuum pump). Connect a micron gauge directly to the pump, blank o,
and start the pump to verify that it is capable of 200 micron vacuum and the gauge is capable of reading that vacuum. Connect
the micron gauge to the access valve installed in the suction line at the evaporator. Remove the Schrader Valve Depressors
from the gauge hoses to reduce restriction and connect gauges to the suction and liquid line service valve service ports on the
Condensing Unit. Connect the pump to the 3/8” hose on the manifold set. Start the pump and run until the micron gauge reads
200 microns.
When a 200 micron level evacuation is achieved, break the vacuum with R-404a and add enough refrigerant to pressurize the
system with a few psi of positive pressure.
Charging
Remove the vacuum pump and the micron gauge. Install a spare low-pressure gauge to the access valve at the evaporator.
With the power o to the Condensing Unit, place the cylinder of R-404a on a digital scale. Admit liquid refrigerant to the system
through the high-pressure side (liquid line service valve) until about 4 1/2 lbs have been added. Shut o refrigerant ow to
system.
Fill a wine bottle ¾ full with water between 60-75°F. Insert the bottle probe into the neck of the bottle as far as possible. (It is
important the bottle probe stopper is compressed by the neck of the bottle to ensure water will not leak out). Verify that the
bottle probe is properly installed and the set point on the controller is low enough to allow the system to run continuously for 30
minutes or more. Turn on power to the Condensing Unit and the compressor should start if suction pressure is above 20 psi. If the
system pumps down and the compressor shuts o, set the 5 minute time delay relay time to the lowest setting to avoid having to
wait. Add refrigerant as a vapor through the low-pressure side of the system (suction service valve port).
Observe the sight glass when the compressor starts. If bubbles are present, slowly add more refrigerant in vapor form to the low
side. The suction pressure and head pressure should increase as the sight glass clears. Check the superheat during the charging
process. Superheat = suction line temp - evap temp. If the superheat drops to 4-5°F and sight glass still has bubbles, let the unit
run until the wine cellar temperature drops and approaches 55°F. Observe the sight glass. If bubbles are present, add additional
refrigerant in small increments. Let the system stabilize for about 5 minutes and check the sight glass for bubbles before adding
additional refrigerant. Once the sight glass is clear, check the superheat at the outlet of the evaporator (evaporator superheat
should be between 8-12°F). If superheat is not between 8-12°F, make an adjustment to the expansion valve. Depending on the
temperature, the high side should be approximately 300-330 psig, and the low side should be 78-82 psig or more to keep the
evaporator from icing.
Measure Superheat
If superheat is high and bubbles are present, add more refrigerant until it is clear. If superheat is low (around 4-6°F) and bubbles
are present in the sight glass, check for liquid refrigerant entering the compressor as evidenced by cool crankcase below 100110°F and low discharge superheat. Adjust TXV setting in small increments to increase superheat and stop liquid from going to
the compressor. Check this before adding more refrigerant. If the temperature of the air entering the condenser is cold enough to
cause the condenser fan to cycle, block about 60% of the coil to raise the head pressure and allow time for stabilization. Reduce
blockage if the condensing temp is above 115°F Fahrenheit. Retain blockage if necessary to maintain stability for performance
test listed in the Split System Warranty Checklist. If the air is cold, below 60°F entering the condenser and the sight glass is clear;
allow the system to run for a while until the cellar cools o, then measure and record data on the Split System Warranty Checklist.
Conrm the controller is displaying the correct temperature and that the controller is not displaying an alarm. If the controller
is displaying an alarm, reference page 26 for corrective action. Conrm that the suction line is completely insulated, from TXV
to compressor. Conrm that the sight glass has no bubbles and the ambient temperature around the Condensing Unit is not
getting excessively hotter. Conrm that both king valves have been back seated and the nuts have been installed back on the
king service ports.

SYSTEM OPERATION
Initial Start-Up
When power is applied to the unit, the control will briey
display all symbols, and the Snowake symbol will be displayed
(if unit is calling for cooling). There may be a brief (up to 60
sec.) delay prior to the evaporator fan turning on. When the
evaporator fan is activated the Fan symbol will display.
APST (Advance Product Safety Technology) is a temperature
control feature for the evaporator fan that comes standard with
all WhisperKOOL units. APST ensures that in the possible event
of a cooling deciency, the heat from the indoor fan will not
raise the temperature of the wine cellar, which could otherwise
have an adverse eect on the wine-aging process.
Set Point
The set point is set from the factory (WhisperKool) at 55F°. It
can be adjusted by the customer between 45–67F° in one
degree increments.
Humidity Features
The FON function is an adjustable feature which allows the
customer the convenience of reintroducing some of the
humidity removed by the fan coil during the cooling process.
The FON Function controls the evaporator fan operation
once the set point has been reached. When the bottle probe
has reached the set point (all units are shipped with the set
point of 55°F and a dierential of 1°), the compressor and the
condenser fan will turn o, but the indoor fan will continue
to run for about 5 minutes to re-introduce any moisture from
the evaporator coil. All units come with this feature turned
o. If low humidity is a problem an increase in this setting
will raise the humidity level. The FON function is one of the
many Customer Preference Selection features that allow the
customer the ability to ne-tune the controls.
The Fon parameter can be increased to allow the evaporator
and condenser fans to run for a longer period of time after
the compressor turns o, allowing more moisture to be reintroduced into the wine cellar.
Anti-Short Cycle
The Anti-Short Cycle ensures that the unit will remain o for a
period of ve minutes after the unit has reached the set point
to allow the pressure in the refrigeration system to equalize
prior to starting the compressor.
Low Ambient Conditions
If the condensing unit is installed outdoors (which allows the
condenser to be exposed to low ambient temperatures), the
condenser fan may cycle on and o. The purpose of the fan
cycling is to maintain the system high side pressure, which
will ensure an adequate refrigeration process. The fan cycling
process is accomplished by way of a adjustable pressure
control or fan cycling switch attached to the condensing unit.
Bottle Probe Failure Protection
In the event that a bottle probe should fail, the APST (Advance
Product Safety Technology) will automatically transition the
refrigeration compressor cycles to a pre-determined time
series (based on detailed laboratory testing), which will ensure
that the product is kept within the safe range.
Display
The bottle probe temperature is displayed by default. “Def”
is displayed during Anti-Frost. The air sensing probe and
evaporator probe temperatures can be accessed by pushing
the SET button and scrolling through “PB1” (bottle probe), and
“PB2” (evaporator probe).
Safety Features
Once the cellar has reached the proper Set temperature,
the compressor goes into its pump down cycle. When the
compressor turns o the delay on break timer prevents the
compressor from short cycling.
In the event of a faulty bottle probe, the compressor will cycle
o for 10 minutes and on for 40 minutes. “E1” will be displayed
on the screen.
Alarms
See “Alarm Codes” in Controller Function chart.
Remote Control Panel (standard)
The remote keypad is designed to give the user the ability to
monitor and change cellar conditions when the evaporating
unit is placed in a remote location outside of the cellar.
Anti-Frost Cycle (defrost)
The system will go through an Anti-Frost cycle every 4 hours.
This will shut down the compressor and allow the evaporator
and condenser fans to run to evaporate any frost accumulation
on the coil. The compressor will remain o until the evaporator
coil reaches 40F°, or for a maximum of ten minutes. The unit
will then return to normal operation.

CPSM Mode Press the “Set” and the “DOWN” buttons simultaneously, for 3-5 seconds and you will access
the “Customer Preference Selection Mode” (CPSM). The CPSM allows the customer to “Fine
Tune” the Control Operating System to their applicable choice.
The following CPSM options are available for adjustment:
Fon – Humidity Management Enhancement: This parameter is normally set at 0, which
should provide adequate relative humidity for the cellar.
• An increase in this parameter will increase the Humidity Enhancement (%RH), and a
decrease in the parameter will decrease Humidity Enhancement (%RH).
• Adjustments should be made in increments of 5, with a maximum of 15, and a minimum
of 0.
• After any adjustment to Humidity Enhancement, you should wait a minimum of three
days before making any additional adjustments. This will allow the cellar sucient time
to acclimate to the new setting.
Fof - Humidity Management Enhancement: This parameter is normally set at 15. This
parameter should not be adjusted, as it simply provides an OFF cycle time for the fan
during the compressor OFF cycle. However, the parameter is located within the CPSM as a
convenience to the customer, should it need to be adjusted. CCT - Cellar Pre-Chill Duration:
This parameter is set to 6 hours, but can be changed between 0-23.5 hours.
Con/Cof – Compressor On time (Con) and O time (Cof) with a Probe 1 failure/Alarm. These
parameters are set at Con 40 min/Cof 10 min. In the event that there is a Probe 1 failure/
Alarm, the compressor/refrigeration system automatically starts a predetermined ON/OFF
cycle, which is controlled by the Con and the Cof parameters. The customer can adjust these
parameters to maintain the desired bottle temperature.

3. Maintenance Requirements
The End User is responsible for checking the coils on the condenser unit and vacuuming them every three months to
maintain them free of debris. It is the End User’s responsibility to clean o any accumulated dust, lint, or other debris from
the front and rear intake grills; failure to do this on a regular basis will restrict the airow and may aect the Product’s ability
to function properly. Periodically cleaning the Product’s vents will help assure maximum cooling eciency. The drain tube
must also be checked and kept clean and free of debris and mold to maintain proper performance.
Mold is a natural living organism in the environment. It exists in the air in the form of microscopic spores that move in and
out of buildings through doors, windows, vents, HVAC systems and anywhere else that air enters. Once it is discovered,
mold must be addressed quickly and appropriately. Delayed or improper treatment of mold issues can result in costly and
reoccurring repairs. If the End User suspects a mold problem, it is always best to hire a qualied and experienced mold
remediation specialist.
