General Description
View the Overview Illustration on page 9 for details.
The Wine Guardian cooling unit is a professional, USA manufactured, self-contained climate
control unit designed specifically for the storage of wine at cellar temperatures. It is designed for
easy installation and operation. Wine Guardian uses digital electronic controls and environmentally friendly R-134a refrigerant. The entire unit is run tested at the factory and shipped as a
single package. All components are of a high quality standard commercial grade. The entire unit
is approved by ETL according to UL 1995 and CSA safety standards. All wiring complies with
NEC. Each unit is furnished with a sealed, UL approved power cord and plug.
The Wine Guardian unit is completely self-contained and includes an integral air or water cooled
condenser. The unit is functionally divided into two sections, the evaporator or cooling section and the
condenser or heat rejection section. Each section contains a coil to add or remove heat and a fan to
move the air through the coil and into or out of the cellar or adjacent space. The Wine Guardian unit is
designed to be used either as a free blowing, through the wall unit or as a remote mount unit with
external ductwork connections.
Air from the cellar first enters a filter to remove any airborne dust particles and then enters the cooling
coil. Air passes through the cooling coil and is cooled by the refrigerant inside the coil. This causes any
excess humidity in the air to condense and be captured in the drain pan and piped outside the unit. Air
then enters the fan where it is pressurized and discharged out of the unit. Optional heating coils are
located between the cooling coil and the fan. These coils heat the air to prevent low temperatures in the
cellar. The thermostat, located in the cellar, turns on the cooling or heating as needed to maintain its set
point. It does not allow the cooling and heating to be on at the same time.
The compressor and condenser sections are activated whenever the unit is cooling. The condenser fan
draws air from the surrounding or ambient space either directly or through a duct. The air is first drawn
through a filter to remove any airborne dust particles to keep the coil clean. Then the air flows through
the condenser coil where it absorbs heat from the refrigerant in the coil. The air is finally discharged out
of the unit by the condenser fan.
IMPORTANT
The air exhaust from the condenser fan is hot and will be 25 to 35 degrees F
above the entering temperature. This may cause overheating problems in the
summer months, especially with high humidity. Exhaust the hot air to the
outside. In the winter, this heated air can help to heat the surrounding space.

Standard Specifications
IMPORTANT
Design and specifications are subject to change without notice
The Wine Guardian Unit Contains
√ A thermal expansion valve to control the flow of refrigerant into the evaporator coil
√ A filter dryer to keep the refrigerant clean and free of contaminants
√ A sight glass to observe the level of refrigerant
√ An automatic low pressure switch to prevent low suction pressures and frost formation
on the coil
√ A manually reset high pressure switch on the discharge to protect the compressor from
high pressures
√ The unit uses only environmentally friendly refrigerant R-134a.
√ A built-in condensate drain trap. No external trap is required.
The Wine Guardian meets or exceeds its rated capacities for total BTU/H and CFM at design
cellar conditions and external static pressures. Both the evaporator and condenser fans are
capable of rated CFM against the external static pressure imposed by recommended ductwork.
Both fans are motorized impeller plug fans, statically and dynamically balanced, and use permanently lubricated direct drive motors requiring no maintenance.
All exterior framing of the Wine Guardian is powder coated, 0.063" gauge aluminum to prevent rust
and corrosion. All coils are copper tubes with aluminum fins. The unit uses an external drain to remove
excess moisture and not reintroduce it into the cellar or ambient space. Removable, multiple access
doors are provided to facilitate cleaning and maintenance, duct connections, and access to components and wiring.
Both the evaporator and the condenser coils have pre-filters on the inlet to prevent dust and dirt from
fouling the coils, thereby reducing capacity. Each unit has at least three discharge outlets on both the
evaporator and the condenser coils to facilitate custom installations.
Each unit is provided with a pre-wired and tested electronic digital thermostat for remote mounting in
the cellar. The thermostat has multiple control functions for the fans, cooling and heating. It has a fully
automatic mode to switch between heating and cooling.
Compressors are rotary, self-lubricating, permanently sealed, hermetic reciprocating type compressors with internal overload protection and capacitor start with a minimum of one year manufacturers warranty and an optional five year warranty. Compressors are mounted on rubber-inshear isolators to reduce noise and vibration.
Electric power is supplied by a single factory furnished cord and plug. All external controls are 24 volt
supplied from an internal transformer. The 230 volt units are capable of operating at 208 or 240 volts
by changing the leads on the control transformer. See Wiring Diagrams .
5
Accessories and Optional Equipment
Heating Coils
An optional heating coil is built-in and requires no additional power source. The electric heating option is
factory installed and includes primary and secondary over temperature protection devices per UL and NEC.
Water Cooled Option
A water cooled option is available that uses a tube-in-tube heat exchanger in place of the condenser coil
and fan. Waste heat from the refrigerant is transferred to the water. A control value is used to regulate the
flow of water to maintain head pressure.
Duct Collars and Flexible Ducts
Ducting for the Wine Guardian is sold in kits by size for each unit. Each kit contains two adapter collars,
one 24ft. length of round flexible duct and two straps. The number of duct kits needed depends on the
layout. The size of the kit depends on the model Wine Guardian selected. Follow installation instructions
carefully. Poorly or incorrectly installed ducts can degrade the performance of your unit dramatically.
Extended Compressor Warranty
The Wine Guardian uses only the best commercially available compressors on the market. However, since the
compressor is the single most expensive component in the unit, it is recommended that you purchase the
extended warranty option.
Low Ambient Option
A factory installed Low Ambient option is available which makes the Guardian capable of exposure to
low ambient temperatures. This feature controls the condenser fan operation based on head pressure and
heats the oil reservoir. The Low Ambient Option (LAO) is recommended whenever the condenser section is exposed to air temperatures below 40°F. This can occur if the unit is placed in a garage or under
an outdoor canopy or if the unit is located inside a heated space but the condenser air is ducted in from
the outside.
Condensate Pump
An optional Wine Guardian automatic condensate pump is available to pump the water to a sink or outside. It
requires a separate 115 volt electrical outlet.
Humidifier and Humidistat
Another popular option for the Wine Guardian is a humidifier. It comes with a sheet metal adapter box
and a pre-wired humidistat. The humidifier is available for field installation and can be retrofitted onto
an existing unit. Each humidifier is furnished with an electronic digital humidistat to control the humid-
6
ity in the cellar. The humidifier mounts directly onto the Wine Guardian unit and uses the common drain.
The humidifier requires a HOT water supply and no additional external power.
CAUTION
CAREFULLY FOLLOW THE INSTALLATIONS INSTRUCTIONS INCLUDED WITH THE HUMIDIFIER. REFER TO THE INSTRUCTIONS CONTAINED IN THE BOX FOR THE HUMIDISTAT.

Overview of the Wine Guardian Unit
Refer to illustrations on page 9
Cabinet – The cabinet and access doors are constructed of aluminum with a powder coated
finish for corrosion protection and an attractive, maintenance free appearance. Areas in contact
with cold temperatures are lined with insulation to prevent condensation.
Condensing Section - Ambient air is circulated through the condenser section by a direct drive,
permanently lubricated, motorized impeller blower. This section also contains the compressor
and the electrical controls. If the water cooled option is purchased, a heat exchanger is used in
place of the condenser coil and blower.
Evaporator Section – Cellar air is circulated through the evaporator section by another blower
the same as above. The large evaporator coil face area eliminates condensate carry-over, reduces air pressure drop and optimizes heat transfer. A drain pan is located directly below the
coil to capture condensate and is fabricated from aluminum to prevent rust and corrosion. The
electric heating coil, if ordered, is factory installed between the evaporator coil and the blower,
and is complete with contactor(s) and limit controls.
Electrical Controls – Most of the electrical components and controls are located in a separate area
accessible through the condenser section. All wiring is in accordance with the National Electrical
Code. Wires are numbered and color coded to match the wiring diagrams.
Factory Tested – All Wine Guardian units are factory run-tested and checked for operational
performance.
Filters – Nominal 1" thick filters are provided on both the evaporator and condenser inlets to protect
the coils from dust and dirt. These filters are washable and reusable.
Humidity Option – The optional humidifier comes fully assembled and tested for field installation onto
the Wine Guardian without any additional electrical power wiring. It automatically adds moisture into
the cellar by the evaporation of water over a distribution pad. A cellar mounted digital electronic
humidistat automatically controls the amount of moisture added.
Internal Drain Trap - Water condensate from the evaporator coil fills the trap and forms a seal to
prevent air from being drawn back through the drain tube. This allows the drain pan to drain freely. No
external trap is required.
Refrigerant Circuit – The factory charged circuit includes a thermal expansion valve with an
external equalizer, sight glass with moisture indicator, a filter dryer, an automatic low pressure
switch, and a manually reset high pressure switch. For the low ambient option, an automatic pressure
switch controls the operation of the condenser blower and a heating element is added to the compressor oil reservoir. See Refrigeration Illustration on next page
Supply/return grilles – Powder-coated steel single direction grilles are provided for the inlets to the
evaporator and condenser sections. One grille is provided on an outlet. These are readily interchangeable with access doors to control and direct the airflow. These grilles may be used in the room on the
end of the ducts in ducted systems .

of the installation instructions before installing the Wine Guardian unit.
20
Planning the Installation
Addressing Items in the Planning Process
√ Where to locate the unit? Should it be built into the wall or mounted remote and ducted into
the cellar.
√ How to mount the unit?
√ Decide where to locate the supply and return grilles in the room to achieve the temperature
gradient and circulation preferred.
√ Locate the electrical power outlet close to the unit. Do not use an extension cord!
√ Does the condenser heat exhaust need to be ducted away?
√ Where to locate the thermostat?
√ Where to run the drain line?
√ Are all the parts here to complete the installation?
Performing a Pre-installation Check
√ Check for the proper installation of the electrical plug configuration
√ Check for the properly sized breaker
√ Is the cellar built with adequate insulation and vapor barriers. See the Wine Cellar Design
Guide at the Wine Guardian’s web site www.wineguardian.com for more information.
√ Are ducts installed above the ceiling or in accessible places properly sized before being
covered.
√ Is enough space available around the unit for service and repair.
21
Locating the Unit
Wine Guardian units are typically installed indoors located near the cellar to minimize the duct
runs. Each unit is provided with one entering or return air inlet and three possible supply air
outlets for each of the evaporator and condenser sections. A maximum cumulative total length
for both supply and return ducts (including bends) of 25’ is recommended. If longer runs are
needed use more than one supply opening to reduce the airflow in each duct by ½. See Recommended Flexible Ductwork Sizing Chart on page 30.
Provide a 3’ clearance around the unit for removal of grilles or ductwork, access to filters and unit
maintenance. If the humidifier is used, provide access space in front of it for service.
Grilles
Each of the inlets and one evaporator outlet and one condenser outlet come from the factory
with grilles over the openings. The grilles are removable. Remove the necessary grilles for
installing ductwork between the unit and the cellar. If desired, use the grilles as wall grilles
inside the cellar. The return air, or inlet, to the unit must connect to the return air outlet from the
cellar. Any of the three supply air outlets on the unit can be used for the ductwork to the supply
grille inside the cellar. The factory installed outlet grille can be relocated to any of the other
two openings. The procedures below apply to both the evaporator and the condenser sections.
In most cases, no ducts are installed on the condenser section because the unit is located in a
mechanical or storage type space. If exhaust heat is undesirable use the grilles to install ductwork
to move the heat outdoors or to another space. Also, use ductwork to direct condenser air noise
away from occupants.
Reducing Noise From the Unit
Consider noise when locating the unit close to the cellar or an adjacent occupied space. A
piece of 1" or 2" dense rubber or styrofoam with foil face in between the unit and the wall
absorbs and reduces the noise from the unit. For air noise use better grilles or block the noise
with a solid piece of wood or styrofoam. Sound usually travels as a line of sight. Sound is
reduced when it turns a corner, such as, passing through a bend in ductwork. If the unit is
supported from a wall or joist, using a rubber pad under the unit will reduce vibration transmission.
22
Installing the Unit Outdoors
The Wine Guardian is NOT designed nor approved for direct outdoor installation. If it is located
outdoors, it MUST be protected with a rain proof enclosure.
• Mount it above the ground on a solid, waterproof base to protect the unit from ground
water.
• Do not locate it where grass clippings or leaves can blow into the unit.
• Keep the area around the unit clean and free of debris.
• Protect from damage when the unit is located in a garage or unheated shed. In both
cases, the unit MUST have the low ambient controls built into the unit.
• Double insulating ducts with exterior grade insulation is recommended to keep the
ducts dry and effective. Wine Guardian suggests installing one sized flexible duct
inside the next larger size duct where ductwork is exposed.
• Allow enough space at both ends of the unit to remove the grilles or ductwork and
allow access to the filters.
Mounting the Unit
CAUTION
RISK OF PERSONAL INJURY OR DAMAGE TO EQUIPMENT
Check supporting structure for load bearing capacity to support the Wine Guardian. All
supports must be designed to meet applicable local codes and ordinances. If in doubt, consult
a qualified architect, engineer or contractor.
Note
Review the mounting illustrations on pages 32 and 33 before mounting the unit.
Floor Mounting
Mount the Wine Guardian on the floor but elevate it on a 2" x 4" frame with a plywood surface to
keep it away from water. Allow adequate space for the external drain.
Wall Mounting
If the unit is mount through the wall, adequately support it on both sides of the wall. Use floor or
knee braces to transfer the load of the unit to the floor or wall.
23
Ceiling Mounting
Construct a structurally sound, level platform to place the unit on when hanging it from the
ceiling joists. The Wine Guardian is NOT designed to be suspended from the top of the unit.
Place the unit on a platform to ensure that the unit is supported on all for corners. Leave adequate space on the top of the unit to remove the access doors for service.
In all cases the unit must be level to within +/- 1/4" end to end and +/- 1/8" side to side for
proper operation. Locate the unit as close to the wine cellar as possible to reduce the length of
the duct runs. If possible, use short and straight ducting on all ductwork. The addition of 1/4” thick
rubber pads helps prevent the transmission of vibration and noise.
Installing the Condensate Drain Connection
The Wine Guardian unit provides dehumidification for the inside of the wine cellar. It cools the air
down to the dew point corresponding to the temperature set point of the thermostat. If the vapor
barrier of the wine cellar is poorly constructed or excess moisture is in the basement, the unit has to
remove excessive amounts of moisture from the wine cellar. The moisture appears in the condensate
drain of the unit.
Note
If moisture becomes excessive, install a room type dehumidifier to dehumidify the basement
so as to not overload your Wine Guardian.
Installing the Drain Line
√ The drain line must extend from the unit to an external drain or disposal site. Do not
use drain tubing any smaller than 1/2” ID on the unit.
√ Splice the drain extension onto the drain outlet with a short piece of 1/2” copper tubing
and secure with clamps
√ If no floor drain is available, use a bucket. Do not extend the drain below the rim of the
bucket. Empty the bucket periodically.
The Guardian Unit is provided with a built-in drain trap. The drain trap creates a water seal to
prevent air from backing up into the drain pan and causing the drain pan to overflow. Do not
create secondary traps in the external drainline.
Allow enough height for the drain line to function properly. If draining into a nearby sink, the unit must
be elevated higher than the rim of the sink in order for the water to drain by gravity. Install with a ¼”
per linear foot of pitch. Do not tie the condensate drain line directly into the sanitary sewer system.
See Accessories and Optional Equipment section for information about the Condensate Pump.
24
Priming the Drain Trap
The internal drain trap primes itself automatically once the unit has run for a period of time and
after the unit cycles off. This is confirmed by water dripping from the drain.
Wiring the Unit for Power
DANGER
ELECTRICAL SHOCK HAZARD
RISK OF SERIOUS INJURY OR DEATH
The electrical outlet and wiring installation must meet the national and local building codes.
DO:
√ Match the electrical outlet to the plug provided on the Wine Guardian.
√ Provide dedicated circuit and wiring for the unit
√ Provide a weatherproof plug for units mounted outside
√ Match the wiring and breaker size to the rated load as shown on the serial plate and in
this guide. See sample Serial Plate illustration below.
Serial Plate
25
DO NOT:
√ DO NOT MODIFY THE PLUGS IN ANY WAY!
√ Do not use extension cords.
IMPORTANT
The electrical power supply must be either 115 volt or 230 volt AC 1 phase 60 cycle,
depending on the model of the unit, and cannot vary more than +/- 4% or damage
may occur to the unit.
Plug the unit into the wall outlet. Gently pull on the plug to make sure it is tight.
Electrical Plug Configuration
Installing the Thermostat and Control Wiring
Each Wine Guardian unit comes with a thermostat and 25’ of wiring. It is wired at the factory
for testing prior to shipment. See start-up instructions in the thermostat guide for installation
and operation of the thermostat.
Note
Keep the thermostat guide in a folder along with the Wine Guardian Manual for future reference.
Removing the Wires for Installation (if necessary)
1) Note the color coding of the wires before removing
2) Using the proper screwdriver, loosen the screws and pull the wire free.
26
Reinstalling the Wires
1) Realign color coded wires
2) Wrap each wire around the screw and tighten the screw.
Adding Additional Wiring
√ Splice onto the factory furnished wire
√ Match the wire colors for continuity
√ Insulate the splice with electrical tape on each wire
CAUTION
RISK OF DAMAGE TO EQUIPMENT
Misconnected thermostat wiring results in improper operation and/or causes damage to the
unit and thermostat. Check each colored wire to its proper color coded slot on the terminal
strip and check that the wires are tight.
Mounting the Thermostat
Each thermostat comes with its own unique manufacturers Installation and Operating Instructions. Use the instructions on how to set and operate the thermostat and to understand how to
install the thermostat.
Mount the thermostat on a solid surface away from doors, corners, air outlets, drafts or heat generating equipment. Do not mount the thermostat directly on an outside wall or wall adjacent to a boiler
room. Use a piece of foam insulation behind the thermostat to insulate it from a hot or cold
surface. The recommended height is 4’ to 5’ above the floor.
Setting the Thermostat
The thermostat has been wired and set up in the factory for testing. It is an electronic digital
thermostat for one (1) stage cooling and one (1) stage heating. No additional adjustments
should be necessary except adjusting the cellar temperature to your preference. Note that the
heating and cooling cannot be set any closer than 3 deg F apart to prevent short cycling. If
additional adjustments or changes are necessary, please refer to the thermostat manufacturer
literature included in the box for detailed installation and operating instructions.
27
Note installation setup number and setting changed from the factory settings.
Setup Number 3 - Changed to 1
Setup Number 5 - Changed to 9
Setup Number 9 - Changed to 5
Setup Number 12 - Changed to 1
Wiring diagram Fig .6 applies (Conventional 1 heating/1 cooling system with one transformer)
The thermostat can receive a battery to light the panel in case of a power failure. It serves no
other purpose and is not required for operation or restart after a power failure.
Time Delays Built Into the Thermostat
Pay attention to the various time delays built into the thermostat as explained in the Thermostat
Installation and Operating Instructions. The time delays are built in to protect the Wine Guardian and its components from damage due to short cycling.
Note
Any time the “cool on” indicator is flashing the unit is waiting for the timer in order to start.
Location of Supply and Return Grilles
Locate the supply and return grilles inside the cellar to create an airflow pattern that maximizes
air circulation in the room. Avoid short circulating of the air.
Do Not:
• install the return air grilles directly on the floor as the grilles will collect dust
from the floor.
• locate the supply or return air grille where it is blocked by bottles, boxes or
cases.
• locate the supply air grille where it blows directly on the thermostat.
Relocating a Grille on the Wine Guardian
1) Remove the fasteners from the grille
2) Remove the fasteners from the access door panel to be replaced by the grille
3) Relocate the outlet grille to its new location and secure in place using its fasteners
4) Replace the access door panel where grille was located.
28
Installing the Ductwork
Use ductwork to connect the unit to the supply and return outlets in the wine cellar. Use only
insulated ductwork to minimize cooling loses, prevent sweating, and to reduce noise.
Use ductwork on the condenser section to redirect or absorb sound, to bring in outside air to the
unit inlet, and/or to exhaust the hot air out of the ambient space.
NOTE
Do not exceed a total of 25’ for each length of ductwork run.

CAUTION
RISK OF DAMAGE TO EQUIPMENT
Avoid crimping the flexible ducts. This chokes down the inside area and reduces the airflow
causing the unit to operate erratically.
Be sure all ducts and surface in contact with the airflow are Insulated and have a vapor barrier
on the outside surface.
29
Uninsulated ducts and surfaces cause bare exposed metal surfaces to sweat,
further degradation of the insulation and a loss of equipment cooling capacity.
General Duct Recommendation
√ Support the flexible duct often to prevent sags or bends.
√ Stretch the duct to make for a smoother interior for less air resistance.
√ For 90° bend insert a metal elbow inside the flexible duct to avoid crimping.
√ Do not squeeze or reduce the inside diameter of the ducts. This restricts the airflow.
√ Use short and straight ductwork.
√ Review the configuration schematic on the Overview Sketch on page 9 for information
about which panels are available for duct connections and service.
√ Remove the panels or grilles from the openings to connect the ductwork.
√ Check that all the fan blades move freely.
√ Check for loose foreign objects in any of the air paths.
√ Connect the round flexible ducts to the Wine Guardian using the duct collars provided
with the duct accessory kit.
√ Pull the outer plastic wrapping and insulation away from the end of the duct to expose
the reinforced inside duct liner.
√ Use tie straps of clamp around the inside liner to fasten the duct collar.
Do not clamp around the outside insulation. It compresses and loosens over time.
√ Secure the duct collar to the unit using the screws provided. Be careful not to damage
or bend the gasket.
Not Using Ductwork
√ The supply and return grilles stay on the unit if no ductwork is used.
√ The supply and exhaust grilles may be relocated to any of three openings. (Refer to the
manufacturers installation instructions located in the box of flexible ductwork).
30
Using Ductwork
Cold Air to/from Wine Cellar
√ Remove supply air grille or access door panels to install ductwork between the Wine
Guardian unit and the cellar.
√ Connect the supply air ductwork from the cellar to the Supply air outlets at the Wine
Guardian Unit.
√ Connect the return air ductwork from the cellar to the return air inlet at the Wine Guardian Unit.
Warm Air to/from Condenser
√ Connect ductwork on the condenser to direct heat and the air noise away from occupants.
√ Connect ductwork to another space within the basement, a building or to the outdoors if
the heat being exhausted is undesirable.

36
Starting-up and Operating the Wine
Guardian
Now that the installation is complete, it’s time to start the unit up. Check to make sure all ductwork and
electrical connections are secure.
Replace all panels which were removed during installation. Check that all of the openings in the unit are
covered with either a blank panel, a ductwork connection or a grille.
CAUTION
Rick of personal injury.
Cover all openings of the unit to prevent a hand or finger from access inside
the unit.
Turn on the Unit
Plug in the unit. Turn-on the rocker switch on the side of the unit. The rocker switch lights up to indicate
power to the unit. The unit may not come on right away due to the timer built into the circuiting to prevent
short-cycling. Refer to the thermostat instructions and set the thermostat on AUTO and 55° F.
Testing the Fan
Push the FAN button on the thermostat to switch from AUTO to FAN as indicated on the display screen.
• FAN means the fan runs continuously and indicates that the power is on and the
control circuit is energized and operating.
• AUTO means the fan runs only when the thermostat is calling for cooling, heating, or
the optional humidistat is calling for humidification.
Running the Unit
√ Check unit to confirm the compressor is running, such as the hum of the compressor or
cool air leaving the unit.
√ Check for any unusual noise or vibration, such as clanking or rubbing.
Initially, the unit may run continuously for several hours, up to a day or more, while it lowers the cellar
temperature. Once the unit reaches the set point temperature, it shuts off and starts to cycle on and off as it
continues to lower the bottle temperature to the set point. The cellar air reaches set point before the bottles. If
the cellar temperature started at 750F, the supply air temperature discharged from the unit will probably be 15
to 200F colder. As the cellar temperature decrease to 550F, the supply temperature differential decreases
8 to 120F colder.
37
Cycling the Unit
The fans continue to free-wheel for several minutes when the unit cycles off. This is normal.
If the unit is furnished with a low ambient control, the condenser fan also cycles on and off during cooling. This
maintains the head pressure on the compressor under low ambient conditions, and is normal. The bottom of the
compressor stays warm even when the unit is off to keep the lubricating oil warm and separated from the
refrigerant.
Setting the Thermostat
Normal settings are between 54 and 58°F. If the optional heating coil is furnished, enter a separate
temperature setting to maintain the lower setting. To prevent the unit from short cycling, the setting
between heating and cooling cannot be closer than 3°F.
Regulating the Wine Cellar Temperature
Wine cellars have a natural temperature gradient of 5 to 100 between floor and ceiling. To increase or
decrease the temperature in various zones, change the air flow patterns.
To keep the entire wine cellar at the same temperature, set the thermostat to run the supply fan continuously
and not just when the cooling is operating. Set Fan switch to ON instead of AUTO.
NOTE
To monitor the Cellar Temperature, place thermometers in various locations in the
cellar to monitor the temperature zones. Change the temperature in various zones by
shifting the air flow patterns.
Changing the Air Flow Direction
The grilles furnished with Wine Guardian are single directional.
Rotate the grilles to change the direction of the air flow.
When using multiple supply ductwork balance the air flow between the ductwork. If too much air flows though
one duct but not enough air flows from the other duct, install a damper or other restriction into the duct with too
much air. That will force more air to flow out the other duct.
38
Maintenance
General
WARNING
BEFORE PERFORMING MAINTENANCE ON THE UNIT, READ AND UNDERSTAND THE SAFETY
INFORMATION CONTAINED WITHIN THE SAFETY CHAPTER OF THE WINE GUARDIAN
MANUAL.
DANGER
HIGH VOLTAGE - RISK OF SERIOUS INJURY OR DEATH
High voltages are present in the cabinets. Turn off all power. Use the Lockout/
Tagout procedure before opening panels.
CAUTION
SHARP EDGES
RISK OF SEROUS INJURY
Sharp edges are present on the fan wheels, housing, fins and coils.
Maintenance on Wine Guardian units requires working with high voltage and
sheet metal with possible sharp edges. Only qualified personnel should
perform maintenance. Some tasks require knowledge of mechanical and
electrical methods. Make sure you are familiar with all hazards, general safety
related procedures, and safety labels on the unit.
CAUTION
EXPOSURE TO MICROBIAL GROWTH (MOLD) CAN CAUSE SERIOUS HEALTH PROBLEMS
Standing water in drain pans promote microbial growth (mold) that cause
unpleasant odors and serious health-related indoor air quality problems. If
mold is found, remove it immediately and sanitize that portion of the unit.
The Wine Guardian is designed for minimum maintenance. The refrigerant system is hermetically sealed and requires no maintenance. The fans are permanently lubricated and require no
maintenance. Some maintenance to the unit may be required due to dust or dirt in the air stream.
39
Cleaning the Filters
The evaporator and condenser coils are provided with reusable, washable air filters. The filters
protect the coils from becoming coated or plugged by dust. Frequency of cleaning the filters is
based on the amount of dust or dirt generated in the cellar or basement.
1. Remove the grille or duct collar on the inlet end of the unit
2. Remove the filter covering the face the coil
3. Wash it under warm water
4. Shake off excess water
5. Inspect and clean the face of the coil
CAUTION
SHARP EDGES
RISK OF SERIOUS INJURY
Sharp edges are present on the fins and coils.
6. Reinstall the filter.
7. Replace the grille or duct collar
Cleaning the Condensate Drain System
The condensate drain system traps dust and dirt. Clean the drain system once a year.
1. Shut off the rocker switch and unplug the unit
2. Remove the grille or duct on the evaporator inlet
3. Remove the filter and inspect the drain pan under the coil
4. If drain pan appears soiled, pour some hot water mixed with liquid bleach (diluted
solution) along the length of the pan to flush the dirt down the drain tube
5. Continue this treatment until the drain appears clean and free of dirt
6. Reinstall filter and grille or duct collar
7. Plug in the unit and restart
Cleaning the Humidifier (optional)
If the unit was furnished with a humidifier it requires periodic maintenance. Follow the instructions in the humidifier guide.
40
Heating Coil Option
It is located between the evaporator coil and blower inside the transition duct. It contains the
heating element and high temperature limit switches. The heating coil is wired to work in conjunction with the thermostat. Since the thermostat prevents the heating and cooling circuits from
being energized at the same time, no additional power wiring is needed. We do recommend using
the auto mode on the thermostat so it can switch from heating to cooling automatically. If using
either the heat or cool only mode, the thermostat will not switch automatically.
No additional maintenance is required for the heating coil. To test the heating coil operation, set
the thermostat on heat and set the temperature above the cellar temperature. The supply air
temperature should rise above the return air temperature by an amount shown in the specifications.
Low Ambient Option
The purpose of the Low Ambient Option is to protect the compressor and refrigerant system. It
has two distinct components, a crankcase heater to keep the oil in the compressor warm and
prevent slugging on system start-up and a head pressure control to cycle the condenswer fan on
and off automatically to maintain system head pressure.
To confirm that the system is working, feel the bottom of the heater when the compressor unit has
cycled off. When the unit starts, the condenser fan does not start at the same time as the compressor. The condenser fan starts after the head pressure has built up. As the unit is running the
condenser fan cycles off and on while it holds the head pressure within a fixed range. The amount
of cycling (frequency and duration) depends on the air temperature. The colder the air, the more
frequenct the cycling and with a longer duration.
Maintenance Schedule
Monthly
(or quarterly depending on experience with individual cellar)
√ Check filter and drain trap – clean if needed
√ Check for noise or vibration
√ Check for short-cycling of the unit - a turning on and off of the compressor unit more
than 8 times/hour.
Yearly
(in addition to monthly)
√ Replace filters if worn or plugged beyond cleaning
√ Check evaporator and condenser coils for dirt – use a vacuum with a brush attachment to clean the coils
41
√ Clean condensate pan under the evaporator coil by flushing. Be careful to keep the
drain pans clear of any and all debris.
√ Inspect cabinet for corrosion or rusting – clean and paint
√ Inspect for dirt buildup on or inside the unit. Clean unit by vacuuming or wiping it
down.
√ Check for loose insulation, fasteners, gaskets or connections
√ Check the wiring connections and integrity of cords
√ Examine ducts for any cracks or breach
√ Check fan and solenoid on humidifier
√ Replace humidifier pad (if used)

47
High Pressure Switch has Shut the Unit Down
Every Wine Guardian unit has a manual reset high pressure switch in the refrigeration system. This
switch shuts the compressor and condenser down if the head pressure in the system is too high. It is
intended to protect the compressor. Restricted airflow through the condenser is the most common reason
for the pressure to become too high. This can be caused by dust covering the filter or an obstruction
blocking the airflow in the duct or grille.
Possible Cause
Head Pressure in unit is too high because
an obstruction is restricting air flow through
