INTRODUCTION
Customer Service
Thank you for purchasing a WhisperKOOL cooling system. We strive to provide the highest quality products and the
best possible customer service. If you have any questions about your system, please call us at 1-800-343-9463 or visit
WhisperKOOL.com.
Using the Manual
This Owner’s Manual is intended to assist in the proper maintenance of the cooling system. In order to ensure the
longevity of your cooling unit, the equipment should be installed as outlined in this Owner’s Manual. It is also vital to
establish a proper care and maintenance schedule. Please read and review this Owner’s Manual carefully and keep it
for future reference.
What is the WhisperKOOL Cooling System?
The WhisperKOOL cooling system is a specialized refrigeration system designed for one purpose only: to maintain the
optimal temperature and natural 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. An exterior housing is required for
outdoor condensing unit installations.
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 the wine cellar,
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. It
is designed to cool up to 55°F cooler than the ambient temperature of the space to which the condensing unit is
installed.

PREPARING THE WINE CELLAR
The performance and life of your system is contingent upon the
steps you take in preparing the wine cellar.
Note: Improperly preparing your enclosure or incorrectly installing your
unit may cause unit failure, leaking of condensation, and other negative side eects.
IT IS HIGHLY RECOMMENDED THAT YOU OBTAIN THE ASSISTANCE
OF A WINE STORAGE PROFESSIONAL.
Wine storage professionals work with licensed contractors, refrigeration technicians, and racking companies to build
well insulated, beautiful, and protective wine cellars. WhisperKOOL has provided useful tips to assist in the installation
process. Our recommendations are meant to act as a guide in the process of building a proper enclosure. Your
intended location may have specic needs that we do not address.
Wall & Ceiling Framing
Build wine cellar walls using standard 2x4 or 2x6 construction methods and ceiling joists following the guidelines of
local and state codes in your area. As a general rule, the thicker the walls and the higher the insulation value in your
cellar, the better it will be at maintaining a consistent temperature.
Insulation
Insulation is REQUIRED with the use of the WhisperKOOL product. Standard berglass or rigid foam insulation is
normally used in cellar construction or, in some cases, “blown-in” insulation is used. It is very important that all walls
and ceilings are insulated to keep the cellar temperature as consistent as possible during the summer and winter
months. The R-value, or quality of insulation, is determined by the rate at which heat passes through the insulation.
The higher the R-value, the more resistant the insulation is to conducting heat. Using higher R-values in insulation will
lower your operating costs and unit run time. (R-13 minimum, R-19 recommended, R-30 for ceiling and exterior walls.)
Vapor Barrier
Water vapor creates its own pressure (separate from the air pressure) and will intrude into colder/drier areas. A vapor
barrier is REQUIRED to prevent the intrusion of water vapor so that the cellar can be kept at the correct temperature
and humidity. 6 mil plastic sheeting (recommended) should be applied to the warm side of the cellar walls. The
vapor barrier must also be applied to the outside walls and ceiling. If it is impossible to reach the outside, then the
plastic must be applied from within the cellar. The most common method is to wrap the entire interior, leaving the
plastic loose in the stud cavity so the insulation can be placed between each stud. All of the walls and ceiling must be
wrapped in plastic for a complete vapor barrier.
In areas of high humidity, such as Southern and Gulf States, the vapor barrier will prevent inltration of warm, moist
air. The moist air can cause mold to form, and standing water in drain pans promote microbial and fungal growth that
cause unpleasant odors and indoor air quality problems. If mold is found, remove it immediately and sanitize that
portion of the unit.
Note: High humidity signicantly increases the heat load on the cooling system.
Any break in the vapor barriers (cut, nail hole, over-lapping, etc.) will allow a moisture leak and must be sealed. The
electric conduit is a “duct” for vapor to travel in. The conduit should be caulked and sealed on the warm air end.

MCM 082814
Page 11
Unobstructed Airow
Unobstructed airflow to and from the system is critical for the system’s overall performance and life span. A
minimum three-foot clearance (five-foot is ideal) area is crucial. The air blown by the fans needs to circulate and either
dissipate or absorb heat from the space. The system will operate more efficiently with a greater amount of air to
exchange.
Note: Avoid attempting to camouflage the unit. This will restrict
airflow, and thus the system’s ability to work efficiently.
Door and Door Seal
An exterior grade (1 3/4”) door must be installed as a cellar door. It is very important that weather stripping is attached
to all 4 sides of the doorjamb. A bottom “sweep” or threshold is also required. The door must have a very good seal
to keep the cool cellar air from escaping out of the cellar. One of the most common problems with cooling systems
running continually is due to the door not sealing properly. In cases where glass doors are used and the room size
is close to the recommended system size, the next larger size WhisperKOOL system should be used. This will
compensate for the insulation loss due to the lower insulating rating of glass.
www.whisperkool.com | Page 9
Page 12
Ventilation
The necessity of dissipating heat away from the condensing unit is critical to the performance and cannot be
overstated. As the system operates and cools, a greater amount of heat is generated on the condensing side of the
system. Adequate ventilation is required in order to dissipate heat away from the condensing unit. If ventilation is
inadequate, the exhaust will heat the area or room and adversely aect the system’s ability to cool. In some cases, it
may be advisable to install a vent fan to dissipate heat within the exhaust area on the condensing side of the system.
However, you must have a fresh air inlet as well.
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.

CEILING
Note: The unit comes black. The mounting bracket and front grille
are paintable, enabling you to match your desired color.
Ambient Temperature Factor
The cooling system has the ability to cool a wine cellar eciently to 55°F as long as the ambient temperature of the
area that it is exhausting to does not exceed 110°F. Therefore, you want to exhaust the condensing unit in a space which
will not exceed 110°F and will allow for proper dissipation of the heat exhausted by the condensing unit. Without proper
heat dissipation the system will not have the capacity to keep the wine at a desirable 55°F.
WARNING! 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 less heat gain through the common
wall, the lower the consumption of electricity.

DRAIN LINE
Condensation Drain Line
The condensation drain line tube 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 Mini Ceiling Mount evaporator features a drain line pump system that removes excessive condensate build up in
the drain pan. During operation, the drain pan collects water that drips from the coil. The drain line pump system will
prevent overflow and leaking by allowing for discharge of the additional condensate.
The longevity of the drain line pump may be compromised if the system operates dry. To prevent the pump from
starting dry an anti-siphon device must be installed in the drain line tubing as shown in Figure 9. This device should
be installed in the drain line post pump on the exterior of the evaporator unit. WhisperKOOL recommends to install
the anti-syphon device relatively close to the evaporator because water will remain between the pump and the
device.
NOTE: The anti-siphon device only needs to be used when the drain line is routed below the level of the evaporator
unit. In this case the anti-siphon device should be installed in the drain line at the level of the evaporator unit.
Connecting the Drain Line
Route the drain line to an appropriate discharge location using the
supplied barb coupling and 1/4” tubing.
Do not route the drain line more than 30 vertical ft.

LIQUID TEMPERATURE - MEASURING THERMOSTAT
The WhisperKOOL Series cooling units come equipped with a liquid temperature measuring thermostat. This incorporates the following advantages:
1. Wine is kept in a very precise, controlled environment. This assures a consistent temperature.
2. By measuring liquid rather than air, the cooling unit is protected from rapid cycling caused by uctuations in air
temperature.
Liquid Temperature - Measuring Thermostat
To assure a consistent temperature, place bottle probe at least 3 feet away from the air output and not in the flow of the air.
To Use the thermostat:
1. Locate an empty wine bottle.
2. Fill 3/4 full with room temperature tap water.
3. Place bottle probe securely into bottle.
4. Place bottle with probe level and to the side of the unit in your
wine cellar. It is recommended that it be placed in a central location
of your wine cellar. Avoid pulling too much on the probe cord. It
may become disconnected resulting in non-operation of the unit.
Note: The thermostat can be set between 50°F
and 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.

Use of the Active Humidity Option
Humidity may uctuate in the wine cellar. The Active Humidity Option stabilizes the environment by adding moisture when
the humidity levels drop below your desired level. Using a humidistat and a water source, the Active Humidity Option is able to
regulate and establish a humid environment suitable for wine storage.
Note: The ideal humidity of a wine cellar is between 50-70%.
General Active Humidity Option Recommendations
• Water source needs to have at least 40 psi.
• Water tubing size: 1/4” O.D.
• Water source should be tested for content and characteristics.
• In areas that are known to have hard water, the use of a water softener system is required.
1%
Note: Failure to install a water softener or a ltration system will allow an
excessive particle residue buildup and may lead to system failure.
• Even if the area is not known to have hard water, the use of a ltration system (particle lter) is required.
• Clean the evaporator coil every 3 months to remove particle residue buildup.
• It might be best to use a self-piercing saddle valve as a simple connection to a water source.
• Clean or replace the Misting Nozzle every 12 months.
Do not allow water leakage inside of the Unit.

PREPARING THE CONDENSING UNIT
Electrical Needs
The Condensing Unit requires a dedicated 115V, 20 amp circuit. 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 40.

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. The Condensing Unit requires a dedicated 20amp circuit, non-GFI. Make sure there is a
minimum 3 ft. horizontal clearance in the front and rear of the unit. The unit should be plugged in.
Set the Condensing Unit level and with proper clearances in accordance with the instructions, name plate power supplied,
proper electric disconnect, and fuse protection connected but not turned on and 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 provision for 500 - 600 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.
Refrigeration Lines:
A 1/4 inch O/D copper liquid line is required.

INSTALLING THE CONDENSING UNIT
Refrigerant Piping Procedure
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 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 equal 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 close 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. Check to see if there is a noticeable pressure drop. If so, locate and x leak.
With pressure at 200 psi, check for leaks with a refrigerant leak detector and/or soap bubbles. 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.
www.whisperkool.com | Page 33
Page 36
INSTALLING THE CONDENSING UNIT
Evacuation
Connect the evacuation type 4 valve gauge manifold to 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-134a 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-134a on a digital scale. Admit liquid refrigerant to the system
through the high-pressure side (liquid line service valve) until the refrigerant stops owing or until about 3 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. 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 175 lbs, and the low side should be 28 lbs 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 37 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.
Insulate the 3/8” suction line with cork tape.

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 Johnson 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.
