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 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 technician’s manual. It is also vital to establish a proper care
and maintenance schedule. Please read and review this 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 unit 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 is 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 system is designed to maintain a cellar temperature of 55°F as long as the ambient temperature does not exceed 110°F.
WARRANTY REGISTRATION
In order to activate the warranty of your system, the verication and operational
documentation must be completed by the certied refrigeration technician
installing your system and submitted via mail, fax, or e-mail.

QUICK START GUIDE*
Pump Down Cycle
WhisperKOOL’s split systems operate on a pump down cycle dierent from traditional air conditioners. As such, there is no wiring
between the condensing unit and evaporator unit.
WhisperKOOL units utilize a solenoid valve on the liquid line and a low-pressure switch on the suction line. When the thermostat
calls for cooling, the solenoid valve opens, permitting the ow of refrigerant. The low-pressure switch then signals the compressor
to cycle on.
When the cellar reaches the desired temperature and the thermostat is satised, the solenoid will close, stopping the liquid
refrigerant ow to the TXV valve. The compressor will continue to operate until most of the refrigerant on the low side boils o
and is pumped through the compressor into the condenser coil and receiver. As the suction pressure falls below the pressure
control setting, the low-pressure switch will signal the compressor to cycle o. Most of the refrigerant is now stored between the
condensing unit and receiver.
…………………………………………………………………………………………………
WARNING: Do not utilize a ground fault interrupter, as it will prevent
the unit from drawing the necessary amperage to start the unit.
TXV Adjustments
A. A TXV adjustment may be necessary based on ambient temperatures in the cellar and at the condensing unit.
B. Adjust the TXV until the total superheat measured at the suction line service valve is 20-30°F.
C. Under normal operation, with the wine cellar at 55°F and the ambient temperature at 85°F, the low side pressure should be
between 28-32 PSI and the high side should be between 145-155 PSI.
TXV
The TXV is preadjusted at the factory. If the superheat is not within
20-30° at the service valve, the TXV will need to be adjusted.
ADJUSTING THE TXV
Use a ⁄” hex key to remove the cap from the TXV superheat
adjustment port. With the cap removed, insert the hex key into
the superheat adjustment port. Increase superheat by turning the
hex key clockwise. Decrease superheat by turning the hex key
counterclockwise.
Liquid Line King Valve
This location is used to charge the system with liquid refrigerant
and identify the high side pressure of the system.
Calculating Subcooling
To determine the subcooling of the system, calculate the dierence
between the high side pressure of the system (converted to
temperature) and the temperature of the liquid line. The temperature
of the liquid line will be taken at the outlet of the receiver.
*Saturation temp — liquid line temp
4-6°F SUBCOOLING REQUIRED FOR WARRANTY APPROVAL
*Further system operation information is available on page 39.

BEFORE YOU START
1. Inspect all components prior to installation. If damage is found, please contact your distributor or WhisperKOOL Customer
Service at 1-800-343-9463.
2. The evaporator unit requires a dedicated 115V, 15-amp circuit. The 4000 condenser requires a dedicated 115V, 15-amp
circuit. The 8000 condenser requires a dedicated 115V, 20-amp circuit. Use a surge protector with the unit. Do not use a
GFI (ground fault interrupter) line.
3. No communication cable is required between the evaporator and condensing unit.
4. You are REQUIRED to install a drain line to remove condensation from the evaporator unit.
5. The warranty is not active until a warranty checklist has been received, reviewed, and approved.
6. The system is intended for use in properly designed and constructed wine cellars. Hire a professional wine storage
consultant with a valid contractor’s license to build your wine cellar.
7. WhisperKOOL requires that all split systems be installed by a certified HVAC-R technician only. NATE or equivalent is
recommended.
If you encounter a problem with your WhisperKOOL system, please refer to the Troubleshooting Guide. If you have any further
questions or concerns, or need assistance, please contact WhisperKOOL’s Customer Service at 1-800-343-9463. Please be sure all
testing has been completed prior to contacting Customer Service. Please have your results ready for your representative.

DRAIN LINE
Condensation Drain Line (not provided, but required)
The condensation drain line tube moves excess condensation from the evaporator unit to a proper discharge
location. It is important for the drain line tube to be properly connected in order to prevent leakage and other problems associ-
ated with excess condensation.
Failure to use the condensation drain line tube will void the warranty on the unit.
Drain Line
All systems come with a drain line connection tee and two 90-degree fittings. The unit is equipped with a ½” OD barbed fitting
coming from the drip tray. (NOTE: ½” ID clear PVC tubing will need to be purchased and installed by the installing technician.)
Installation of the drain line is mandatory, whether it leads through the wall and out of the cellar or remains inside the cellar.
During operation, the cooling system will strip excess water from the air in order to maintain the proper level of humidity within
the cellar. However, in extreme humidity, additional condensate will be removed; thus the drain line will prevent overflow and
leakage by discharging the excess condensate.
Routing the tubing out of the unit:
Cut a small piece of ½” tubing and connect one
end to the drip tray port and the other to a
90-degree fitting. (This will direct the tubing
toward the back of the unit where the tube will
exit the unit.) Be sure to extend the tubing far
enough outside the housing to extend through
the wall if necessary.
If routing out of the rear: Cut a piece of tubing
long enough to protrude out of the knockout on
the back side of the unit.
If routing out of the bottom: Cut a piece of
tubing long enough to reach the knockout in
the bottom of the unit and install the supplied
90-degree fitting. (This will direct the tubing out
of the bottom of the unit without the risk of
kinking the tubing.) DO NOT USE TEE WHEN
ROUTING OUT OF THE BOTTOM.
Routing to discharge location if routed out
of the bottom:
Connect the drain line directly to the second
90-degree barb fitting previously installed. Route
the drain line to an appropriate drain location.
No tee is required if draining through the

line coming from the evaporator. Rotate fitting so tee is in the orientation
shown in the diagram below. Connect a 3-inch piece of ½” drain line to
the barb on top. Connect the remaining “long” piece of drain tubing to
the bottom barb of the tee. Route the drain line to an appropriate drain
location.
NOTE: The fitting should be placed
vertically with the 3” cutout facing
up.
Failure to install the drain line
voids the warranty.
To prevent mold from growing,
allow the drain line to hang
above the water line.
WRONG: Drain line is under water.

LIQUIDMEASURING THERMOSTAT SYSTEM BOTTLE PROBE
WhisperKOOL cooling units come with a liquid-temperature-measuring thermostat. The self-calibrating probe contains a sensor chip, which communicates back and forth with the thermostat. This results in a consistent temperature
setting and accuracy. Wine should be kept at a very precise, controlled temperature and humidity. 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 it 75% full with room-temperature tap water.
3. Place bottle probe securely into bottle as seen in Figure 1.
4. Place bottle off to the side of the unit in your wine cellar, with the probe level.
5. To ensure a consistent temperature, place bottle probe approximately three
(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 50–70°F.
Remember: The 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 the optimum balanced temperature.

PREPARING THE CONDENSING UNIT
Electrical Needs
The 4000 condensing unit requires a dedicated 115V, 15-amp circuit. The 8000 condensing unit requires a dedicated 115V, 20amp 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 lowpressure transducer mounted on the condensing unit. This feature eliminates the need for wiring between the evaporator 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.
• Provide a dedicated circuit and circuit breaker for the condensing unit.
• Provide a weatherproof disconnect for the condensing unit if it is located outside.
Power surges and spikes can damage sensitive electrical equipment. 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 Guide on page 47.
www.whisperkool.com | Page 29
Page 32
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. The amount of sun exposure should be considered when selecting
the placement of the condensing unit .The 4000 condensing unit requires a dedicated 15-amp circuit (non-GFI). The 8000
condensing unit requires a dedicated 20-amp circuit. Make sure there is a minimum of three (3) feet of horizontal clearance in
every direction around the unit (ve feet is ideal). The unit may either be hard-wired or plug-in, depending on local electrical
codes.
Indoor 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. There must be a return grille or provision for 500 - 600 CFM
of cool air to enter the room to replace the exhausted air. Unobstructed airow to and from the unit is a critical factor in
the unit’s overall performance. Make sure there is a minimum of three (3) feet of horizontal clearance in every direction
around the unit (ve feet is ideal). 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. Make sure there is a minimum
of three (3) feet of horizontal clearance in every direction around the unit (ve feet is ideal). 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.

Refrigerant Piping Overview
• Using the charts and illustrations found above, 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 half
an inch for every 10 feet 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 half a turn to unseat the valve and open the service
port. Keep the piping ports sealed until ready to braze.
• Purge the ttings with dry nitrogen 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 wall cellular insulation or equivalent. Seal all seams with Armaex 520 Foam Insulation
Adhesive or equivalent. Wrap each seam using line set tape.
Liquid Line Piping Procedure
• Refer to the line set piping chart for liquid line size requirements.
• Braze a short piece of 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 and attach to the liquid line connection on the evaporator unit.
airow andvoidthe warranty.
Suction Piping Procedure
• 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 and attach to the suction line connection on the evaporator unit.
Brazing Procedure
• Connect the bottle probe to the evaporator unit.
• Fill a wine bottle 75% 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 and set the controller to call for cooling.
• Verify that the setpoint 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 the system with nitrogen.
• Braze all connections and cool o quickly.
• 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 conrmed that there are no leaks.
Evacuation
• Remove the nitrogen tank from the manifold and attach the manifold to the refrigerant tank.
• Mid-seat both service valves.
• Install service caps on the valves.
• Energize the liquid line solenoid valve.
• After conrming that there is fresh oil in the vacuum pump, connect the ⁄” hose from the manifold to the pump.
• Start the pump and run it until the micron gauge on the evaporator unit reads 500 microns or less.
• Disconnect the vacuum pump from the system.
• Break the vacuum by pressurizing the system to approximately 5 PSI with R-134a refrigerant.
• Remove the micron gauge from the access valve.

INSTALLING THE CONDENSING UNIT (continued)
Charging
• 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
25 psi.
• Add refrigerant (in vapor form) to the low side of the system through the suction line service port.
• 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. Adjust the TXV until the superheat is
between 20-30°F at the service valve.
• Under normal operation, with the wine cellar at 55°F and the ambient temperature at 85°F, the low side pressure should be
between 28-32 PSI and the high side should be between 145-155 PSI.
Finalizing the Installation
• Conrm that the entire suction line from the TXV to the suction line service valve is insulated using cellular insulation or
equivalent. Seal all seams with Armaex 520 Foam Insulation Adhesive or equivalent.
• Conrm that the control is displaying the correct temperature and that no alarms are present. Refer to page 43 for corrective
action if alarms are present.

SYSTEM OPERATION
Platinum Split
Initial Start-Up
When the unit is plugged in and power is sent to the
controller, a beep will sound, conrming that the controller is
getting power. All LEDs on the display will blink three times.
Three dashes will then appear on the screen. All display LEDs will
then blink three times. Once the controller has gone through
the initial startup process, and all LEDs have cycled, the home
screen will be displayed.
Setpoint
The setpoint is preset at the factory to 55°F. It can be adjusted by
the customer between 50–70°F in one-degree increments.
Indoor Fan Operation
The indoor fan will run when the controller is calling for cooling
and turn o once the cooling cycle has ended. During the
cooling cycle, the system will remove some relative humidity
from the cellar. Some of the humidity that was removed can be
reintroduced into the cellar by adjusting the “fan on” and “fan o”
functions. (The cooling system is not equipped with a humidier
and does not add humidity.)
The FOF cycle should be shortened rst. This will reduce the
amount of time that the fan remains o following a cooling cycle.
When the unit has completed a cooling cycle, the compressor
and the condenser fan will turn o, but the indoor fan will
continue to run for whatever length of time the customer has
set. The Fon function may then be lengthened to allow the fan
to run longer and reintroduce moisture from the evaporator coil
back into the wine cellar.
For more information about fan settings, refer to the User Menu
on page 44.
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 setpoint.
This allows the pressure in the refrigeration system to equalize
prior to starting the compressor.
The compressor will remain o until the evaporator coil reaches
40°F, or for a maximum of one hour. The unit will then return to
normal operation.
Operation in Low Ambient Temperatures
The condensing unit comes equipped with a LAC (Low Ambient
Control). The LAC is a three-way modulating valve that responds
to discharge pressure. When the discharge pressure falls below
the valve’s dome pressure, the valve modulates open to the
discharge port which allows discharge gas to bypass the
condenser. Mixing the discharge gas with the liquid creates high
pressure at the condenser outlet, reducing the ow and causing
liquid to backup in the condenser. Flooding the condenser
reduces the area available for condensing. This reduction in
condenser surface area results in a rise in condensing pressure
during cold ambient conditions.
The condensing unit controller is preset at the factory. The cutin pressure is preset to 25psi and the cut-out pressure at 15psi.
During low ambient temperatures (40°F or below), it will be
necessary to adjust the cut-in pressure to 10-15psi (15psi is
preferred) and the cut-out to 5psi to ensure compressor startup.
See page 44 for instructions on adjusting the cut-in and cut-out
pressures of the condensing unit.
Digital Display
The display is designed to give the user the ability to adjust
the setpoint, Fon/FOF parameters, and other settings. (See
User Menu on page 43 for more details.) The bottle probe
temperature is displayed by default. “dEF” will be displayed
during an Anti-Frost Cycle. The bottle probe and evaporator
probe temperatures can be accessed by pushing the SET button
and scrolling through “Pb1” (bottle probe) and “Pb2” (evaporator
probe). The light button may be used as an unlock button.
Safety Features
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.
Once the solenoid relay is de-energized, the controller must
wait ve minutes before reenergizing the relay. This prevents
the compressor from repeatedly turning o and on. If the unit
is calling for cooling during this time, the compressor icon will
blink, indicating that cooling is needed but the controller is
waiting for the Anti-Short Cycle delay.
Anti-Frost Cycle
When the evaporator probe senses a temperature of 26°F for
a duration of one minute, an Anti-Frost Cycle will be initiated.
This will shut down the compressor, allowing the evaporator fan
to run and melt any frost accumulation on the coil. While the
Anti-Frost Cycle is running, “dEF” will be displayed on the screen.

enhancement of your cellar. This parameter should not be adjusted
to zero. Adjustments should be made in increments of 5, with a
maximum of 15 and a minimum of 1. After making any adjustments
to humidity enhancement, you should wait a minimum of 3 days
before making any additional adjustments. This will allow sucient
time for the cellar to acclimate to the new setting.
FOF - “fan o” This setting controls how long the fan stays o after the setpoint
has been reached. It is preset to 15 minutes. This setting should
not be adjusted, as most properly constructed wine cellars retain
an ample amount of humidity during the “fan o” cycle. If, however,
you wish to decrease the duration of the “fan o” cycle (in order to
increase the wine cellar’s relative humidity), you can adjust this
setting in the User Menu.
Fon - “fan on” The “fan on” time is preset to zero minutes. This keeps the relative
humidity of the wine cellar at a stable level. If, however, you wish
to raise the relative humidity of your wine cellar, you can increase
the duration of the “fan on” cycle in increments of ve (5, 10, or 15
minutes). After making any adjustment to the “fan on” cycle, you
should wait a minimum of 3 days before making any additional
adjustments. This will allow sucient time for the cellar to acclimate
to the new setting.
CA1 - bottle probe (Pb1) calibration CA1 - bottle probe (Pb1) calibration: You may use this parameter
to calibrate the bottle probe to a known temperature. This parameter can be adjusted between -12°F and 12°F. For example, if the
bottle probe temperature is 58°F, and the known temperature is
55°F, you can set the CA1 parameter to -3°F to match the known
temperature.
PA2 - installer menu This menu is only accessible using a password and is not available
for adjustment.
dOA - digital input This setting determines which of the unit’s components will be
activated or deactivated when a certain electrical relay is activated
or deactivated in response to an alarm. The controller comes preprogrammed with a factory setting of 2.
Page 44 | 1-800-343-9463
2 = activates the compressor and fans
5 = disables the compressor and fans
NOTE: Setting the dOA to any number other than 2 or 5 will prevent
the unit from operating properly.

Care and Cleaning of
Air Cooled Condensing Units
Introduction
Proper care is essential to assure good life of condensing
units. Dirty or damaged condensers will reduce the
efciency and capacity of the system.
Care must be taken in choosing solutions to be used for
cleaning condensers and condensate pans. Chlorinated
cleaners and anti-bacterial cleaning agents can be
damaging and should be avoided. Caustic and acidic
cleaners should be avoided as well. Failure to do so
may accelerate component corrosion and ultimately
lead to component failure.
Condenser Coils
There are many commercially available condenser coil
cleaners on the market. Coil cleaners should be designed
to remove build-up on ns and coils. Coils should be
thoroughly rinsed of the cleaners once cleaning has
been completed. Follow the manufactures instruction
for proper usage. Preventive maintenance and routine
cleaning of coils is important to assure good life.
When cleaning the coil, an absorbent type material
should be placed under the area to be cleaned in
order to capture most of the cleaning compound, thus
minimizing any type of chemical attack.
Condensate Pans
Condensing units with condensate pans and condensate
tubes are designed to evaporate condensate water
only. Other ingredients introduced into the condensate
pan can accelerate pan and/or tube corrosion. As
foreign agents are introduced into the condensate pan,
condensate water will be evaporated leaving the foreign
agent behind. This can lead to a high concentration of the
agent and possible corrosion of the tubing and/or base.
October 2006
Coil cleaning agents must not be allowed to drain into
the condensate pan as this may cause damage. Upon
completing the coil cleaning, be certain that all residue
is removed from the condensate pan.
Only non corrosive cleaners should be used to assure
good life of the condensing unit components. No
hydrocarbon based cleaners should be used to clean
the unit. Bleach solutions must be avoided due to its
high corrosive nature.
Under no circumstances should cleaning agent
ingredients contain any of the solutions listed below:
Unacceptable solutions are:
Chlorinated Solvents
Bleaches
Vinegar
Ammonia
Anti-Bacterials
Salts
Preventative Maintenance
Maintenance should be performed at regular intervals.
Coils should be cleaned at least monthly, possibly more
depending on the environment. Condensing units with
condensate pans should also be checked and cleaned
regularly to prevent damaging build up in the pan.
Safety
Please follow all safety recommendations listed by the
manufacturer of the cleaning agent(s), these would
include proper clothing, gloves and eye protection.

ACCESSORIES FOR COOLING UNITS
WhisperKOOL offers accessories to enhance and customize your wine cooling unit:
Condensate Pump Kit
The condensate pump kit automatically removes water that drips out of the evaporator unit’s drain line. The pump is controlled
by a float/switch mechanism that turns the pump on when approximately 2¼” of water collects in the tank, and automatically
switches off when the tank drains to approximately 1¼”. The condensate pump kit allows the excess condensate to be pumped up
to 20 feet away from the unit.
Exterior Housing
If the cooling unit is installed outside, it will need protection from sun, wind, and rain. The exterior housing protects the condensing
unit portion of the split system from the elements when installed outdoors.
Accessories can be purchased at www.whisperkool.com

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 off 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 airflow and may affect the Product’s ability to function
properly. Periodically cleaning the Product’s vents will help assure maximum cooling efficiency. 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 qualified and experienced mold remediation
specialist.

determined in a written report. This report will be made available to all concerned parties. If discovered under warranty,
