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 the 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 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 eects.

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 specic 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 mm 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 inltration 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 signicantly 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.

www.whisperkool.com | Page 9

Page 12

Unobstructed Airow

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.

WCM 033114

Page 13

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 aect 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

UNIT

Note: The unit comes black. The mounting bracket and front grille

Ambient Temperature Factor

The cooling system has the ability to cool a wine cellar eciently 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 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.

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 115 volt 20 amp circuit. The unit draws a large inrush current for about

one second the instant the compressor starts. With a dedicated circuit and circuit breaker, the condensing unit will have sucient power for eective 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 specied on the unit spec label.

• Provide a non GFI dedicated circuit and an appropriate outlet for the evaporator unit.

• Provide a dedicated circuit and circuit breaker for the condensing unit.

• Provide a weatherproof disconnect for condensing unit 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 and 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 section on page 48.

Low Ambient Control (Cold Weather Start)

All WhisperKOOL split systems come equipped with a compressor heater and fan regulator switch allowing the condensing unit to operate when the ambient temperature is as low as 20°F. The heater serves to prevent liquid refrigerant from entering the compressor while the system is not running. In addition, in cold weather conditions, the heater keeps the condenser warm which helps to operate the system. The fan cycling switch will prevent the fan from operating if the pressure it too low allowing the system to warm up to the needed temperature to operate eectively. When the low ambient temperature is below 20°F an extra heat source kit is necessary to allow the condensing unit to start up.

PREPARING THE CONDENSING UNIT (continued)

Installing the Condensing Unit

The condensing unit can be installed inside a well-ventilated area of the home, but 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 20 amp circuit (non-GFI). Make sure there is a minimum three-foot horizontal clearance in the front and rear of the unit. The unit may either be hard wired or plug-in, depending on local electrical codes.

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 eectively 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 airow to and from the unit is a critical factor in the unit’s overall performance. Make sure there is a minimum three-foot horizontal clearance in the front and rear of the condensing unit and at least one foot on each side. This will assure that the unit can move the air around the room in an ecient 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 of 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 ooding or damage by animals, and should be clear of leaves, dirt, and other debris.

INSTALLING THE CONDENSING UNIT

Refrigerant Piping Overview

• Using the charts and illustrations found on previous pages, route the line set between the evaporator unit and

condensing unit. Be sure to reference the chart for correct line set sizing. All horizontal suction piping should be pitched toward the condensing unit ½” for every 10’ of pipe. When installing and routing the line set, cap both ends of each tube to prevent debris from entering the tubing.

• Prior to connecting the piping to the evaporator and condensing units, loosely connect a refrigerant manifold to

the suction and liquid line service valves.

• Purge the hoses with dry nitrogen and tighten the hose connections.

• Remove the service valve caps and turn the valve stem clockwise ½ turn to unseat the valve and open the

service port. Keep the piping ports sealed until ready to braze.

• Purge dry nitrogen through the ttings at a slow rate to prevent formation of highly abrasive copper oxide.

• Perform all brazes.

• Pressure test the system and check for leaks.

• Insulate the suction line using ½” wall cellular insulation or equivalent. Seal all seams with Armaex 520 Foam

Insulation Adhesive or equivalent. Wrap each seam using line set tape.

Liquid Line Piping Procedure

• ¼” OD copper tubing is required for the liquid line on all systems.

• Braze a short piece of ¼” copper tubing to the liquid line service valve.

• Connect the supplied refrigerant drier to the tubing.

• Downstream from the drier, connect the moisture indicating sight glass in an easily visible location.

• Run the tubing to the evaporator unit (fan coil unit) and attach to the liquid line connection on the evaporator

unit (fan coil unit).

Suction Piping Procedure

• Install an access valve at the outlet of the evaporator unit (fan coil unit).

• Connect an appropriately sized suction line to the suction line service valve on the condensing unit.

• Run the pre-insulated suction line to the evaporator unit (fan coil unit) and attach to the suction line connection

on the evaporator unit (fan coil unit).

Brazing Procedure

• Connect the bottle probe to the evaporator unit (fan coil unit).

• Fill a wine bottle ¾ full of room temperature water. Insert the bottle probe into the neck of the bottle as far as

possible. It is important that the bottle probe stopper be compressed by the neck of the bottle to ensure water will not leak.

• Energize the evaporator unit (fan coil unit) and set the controller to call for cooling.

• Verify that the set point on the control is set low enough to allow the unit to run for the entire length of the

brazing, evacuation, and charging procedure.

• Remove the valve depressors from the gauge hoses on a four-valve manifold.

• Connect the manifold to the low-pressure service valve port on the condensing unit and a nitrogen tank.

• Open the suction line service valve and purge nitrogen through the system.

• Braze all connections and cool o quickly.

• Cap the access valve on the suction line.

• Connect the high-pressure hose from the manifold to the liquid line service valve port.

• Pressure test the system at 150 psi for 20 minutes.

• Check all braze joints with leak detector or soap bubbles.

• Release the nitrogen once it is conrmed that there are no leaks.

www.whisperkool.com | Page 41

Page 44

INSTALLING THE CONDENSING UNIT

Evacuation

• Remove the nitrogen tank from the manifold and attach the manifold to the refrigerant tank.

• Install a micron gauge onto the access valve near the evaporator unit (fan coil unit).

• Mid seat both service valves.

• Install service caps on the valves.

• Energize the liquid line solenoid valve.

• After conrming there is fresh oil in the vacuum pump, connect the 3/8” hose from the manifold to the pump.

• Start the pump and run until the micron gauge at the evaporator unit (fan coil unit) reads 200 microns or less.

• Disconnect the vacuum pump from the system.

• Break the vacuum by pressurizing the system to approximately 5 PSI with R-134a.

• Remove the micron gauge from the access valve.

Charging

• Install a low-pressure gauge on the access valve near the evaporator unit (fan coil unit).

• With the power o to the condensing unit, admit liquid refrigerant through the liquid line service valve until the

refrigerant stops owing.

• Turn on the circuit breaker for the condensing unit. The compressor should turn on if the pressure in the suction

line is above 20 psi.

• Add refrigerant as a vapor through the low side of the system.

• Observe the sight glass. If bubbles are present, add more refrigerant in vapor form to the low side.

• Once the sight glass is clear, check the superheat at the outlet of the evaporator unit (fan coil unit). Adjust the TXV

until the superheat is between 8-12 degrees.

• If TXV adjustment is necessary, remove the drip tray on the evaporator unit to access the TXV from the cellar.

The drip tray is secured to the wrapper with two screws. Once the screws are removed the drip tray will slide down and out of the evaporator unit.

• Under normal operation, with the wine cellar at 55° and the ambient temperature at 85°, the low side pressure

should be between 28-32 PSI and the high side should be between 170-180 PSI.

Finalizing the Installation

• Conrm that the entire suction line from the TXV to the suction line service valve is insulated using ½” wall cellular

insulation or equivalent. Seal all seams with Armaex 520 Foam Insulation Adhesive or equivalent.

• Reinstall the drip tray and Front Access Panel.

• Conrm that the control is displaying the correct temperature and that no alarms are present. Refer to page 45 for

corrective action if alarms are present.

FINALIZING THE INSTALLATION

1. Push the Grille Back into place. This will attach the

grille to the ball studs.

SYSTEM OPERATION

Initial Start-Up

When power is applied to the unit, the control will briey display all symbols, and the Snow Flake symbol will be displayed (if unit is calling for cooling). There may be a brief delay prior to the evaporator fan turning on. When the evaporator fan is activated the Fan symbol will be displayed. The temperature control feature for the evaporator fan is a feature applicable to WhisperKOOL. This is the Advance Product Safety Technology (APST), which ensures that in the possible event of a cooling deciency, the heat from the indoor fan will not raise the temperature of the wine cellar, which could otherwise have an adverse eect on the wine-aging process.

Normal System Cycle

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 is a feature that controls the evaporator fan operation once the set point has been reached. All units are shipped with the set point of 55°F and a dierential of 1°F. 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.

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 predetermined time series (based on detailed laboratory testing), which will ensure that the product is kept within the safe range.

Remote Keypad (standard on ducted units)

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-Short Cycle

The Anti-Short Cycle ensures that the unit will remain o for a period of 5 minutes after the unit has reached the set point to allow the pressure in the refrigeration system to equalize prior to starting the compressor.

Anti-Frost Cycle

The Anti-Frost Cycle is a precautionary measure, as icing or frosting of the coil does not occur during normal operation. The system will go through a defrost cycle every 4 hours. During the defrost cycle, the indoor fan will provide airow across the indoor coil, which will evaporate any frost accumulation.

Low Ambient Conditions

If the condensing unit is installed outside (which will allow 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.

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 sucient 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. No one has any authority to add to or vary the limited warranty on this Product.

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 airow and may aect the Product’s ability to function properly. Periodically cleaning the Product’s vents will help assure maximum cooling eciency. 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 qualied and experienced mold remediation specialist.

4. Additional End User Costs And Responsibilities

When a claim for warranty is submitted for a condenser skid, the End User must purchase a new condenser skid from WhisperKOOL at retail price. Upon installation of the new condenser skid by a certied HVAC/R Technician, the HVAC/R Technician must complete the Installation Checklist and End User must submit the Installation Checklist to WhisperKOOL Customer Service for approval. The original condenser skid must be returned within 21 days to WhisperKOOL for failure analysis. If the Installation Checklist is approved and the failure is evaluated as defective and not installation error or other reason, the End User will be refunded for the cost of the replacement skid.
