General Description

View the Overview Illustration located on page

The Through-the-Wall Wine Guardian cooling system is a professional grade, self-contained climate control system 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 system is run-tested at the factory and shipped as a single package. All components are of a high quality standard commercial grade. The entire system is approved by ETL (Equipment Testing Lab) according to UL (Underwriters Laboratory) 484 and

CSA (Canadian Standards Association) safety standards. All wiring complies with NEC (National

Electrical Code). Each system is factory installed with a sealed, UL-approved power cord and plug, that can be mounted on either end of the cooling system. Wine Guardian products are made in the

USA.

The Wine Guardian Through-the-Wall system is completely self-contained and includes an integral air cooled condenser. The system 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.

Air from the cellar first 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 internally evaporates as it comes in contact with the integral condensate removal coil. Air then enters the fan where it is pressurized and discharged out of the system. The thermostat, located on the system, or through the optional remote interface controller, turns the cooling on and off as needed to maintain its set point.

The compressor and condenser section are activated whenever the system is cooling. The condenser fan draws air from the surrounding or ambient space. 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 system by the condenser fan, and can be ducted ouside or to an unused space by an optional condenser duct kit.

CAUTION

The air exhaust from the condenser fan is warm and can be 20 degrees F above the entering air temperature.

Wine Guardian Controls

Wine Guardian’s digital electronic control series offers a versatile solution for controlling and monitoring your wine cellar temperature and humidity. This series consists of four controls; a main control board; a local user interface; a remote user interface; and a remote temperature and humidity sensor. The system only requires the use of the main control board and one of the user interfaces (local or remote) to function.

However, users have the following options to customize the control capabilities for their application: (See page 6 for description of control boards and optional sensors).

The Wine Guardian’s digital electronic controls are designed to control the operation of the compressor, condenser fan, evaporator fan, and humidifier. There also is pressure switch monitoring with a dry contact alarm output that will energize in the event of a pressure switch fault or a high/low temperature or humidity alarm. The local and remote user interface controls employ user-friendly, menu-driven programming features that can easily be accessed by holding the mode button on the control for 5 seconds. Once in the program menu, the user can scroll through the settings by pressing the mode button and can adjust each setting by using the up and down arrows. The programming mode allows the user to customize features such as °F or °C temperature scale, high/low temperature and humidity alarm set points, an adjustable 0-10 minute compressor anti-short cycle delay, sensor averaging options, enable or disable the defrost feature, an optional keypad lockout code, differential and dead band adjustments, room temperature calibration, enable or disable the humidifier, and automatic or continuous fan option. To exit the programming mode the user may either hold the mode button for 5 seconds or the control will automatically store the settings and exit the programming mode after 10 seconds of inactivity. Each user interface control will also employs and ON/

OFF button that turns the system on or off respectively.

One way communication: remote temp/humidity sensor reports temp and humidity readings to main control.

Two way communications: remote user interface reports settings back to main control, main control energizes outputs and reports alarms and temp/humidity readings to remote user interface.

6

Local User Interface: Can be used with Main Control for adjusting settings, reading temp/humidity, and reading fault codes at the unit.

Remote User Interface: Can be used with Main Control for adjusting settings, reading temp/humidity, and reading fault codes in a remote location away from the unit.

Temperature/Humidity Sensor: Can be used in conjunction with the Main

Control to report temp/humidity from inside the wine cellar without requiring a user interface to be located inside the wine cellar.

Standard Specifications

IMPORTANT

Design and specifications are subject to change without notice

The Wine Guardian System Contains

√ A capillary tube expansion to control the flow of refrigerant into the evaporator coil

√ A filter dryer to keep the refrigerant clean and free of contaminants

√ Dual factory mounted plastic supply/return air grilles for evaporator and condenser air movement

√ Movable suply air louvers for side-to-side directing of cold air into the wine cellar

√ A manually reset, high-pressure switch on the discharge to protect the compressor from high pressures

√ Environmentally friendly R-134a refrigerant

√ An internally/externally mounted digital electronic control with many user-controlled settings

√ Auxiliary drain port connection at condenser end of unit

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 evaporator is coated with an “E” coat finish to prevent premature corrosion.The system uses an internal drain system to remove excess moisture and not reintroduce it into the cellar or ambient space. An auxiliary drain port is located at the condenser end of the unit should there be a need to physically remove the excessive moisture.

Each system is provided with a pre-wired and tested electronic digital thermostat (local user interface) as standard, or an optional remote mounted thermostat (remote user interface) in the cellar. The thermostat has multiple control functions for the fans, cooling and heating (if equipped), and maintaining humidity.

Compressors are 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-in-shear isolators to reduce noise and vibration.

Electric power is supplied by a single, factory-furnished cord and plug that can be connected on the cellar side or the condenser side of the system. Systems are shipped from the factory with the plug attached on the condenser side. (to switch plug to the cellar side see page ???of this manual.) All external controls are 24-volt supplied from an internal transformer.

Accessories and Optional Equipment

Installation Sleeve

Each Wine Guardian system includes an EasyMount TM installation sleeve to be used in the mounting of the system through-the-wall at the desired location. The sleeve is essential for the proper support of the Wine Guardian system and ease of installation. The maximum dimensions of the wall opening should be 14-1/2” wide by 16-1/4” high.

For proper operation of the system, including drainage and undue noise and vibration, the Installation

Sleeve must be mounted level within the wall cutout and securely fastened to the wall studs on either side of the sleeve as shown on page 20.

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 system, it is recommended that you purchase the extended, five-year warranty option.

Duct Collar Adapter

An optional duct collar kit is available for ease in directing the warm condenser air away from the through-the-wall unit mounting. The kit includes one (1) duct collar, 15-feet of 6-inches round flexible ductwork and two(2) tie wraps for connection of the ductwork to the duct collar. The kit does not include connections at the tie-in point to the remote location or outdoors.

Remote Temperature/Humidity Controller

The remote temperature/humidity controller (Remote Interface Controller) is intended to provide a means for user interface at a remote location. The controller can be used as a remote sensor/controller mounted within the wine cellar remote from the Through-the-Wall system. The controller also can be used as a remote controller (without sensor) or indicator mounted directly outside the wine cellar or in another part of the residence or building. The Remote Interface Controller includes a backlit face for temperature and humidity indication along with controller set-up and operational functions.

Remote Temperature/Humidity Sensor

The remote temperature/humidity sensor is intended to provide a means of sensing one or more locations within the wine cellar and is designed to work in conjunction with the Remote Interface

Controller or Local Interface Controller integral to the Wine Guardian Through-the-Wall system. Multiple sensor readings are averaged and controlled to a single point. The sensors do not have any temperature or humidity indication and must be mounted within the wine cellar area being controlled.

Humidity Option – An optional stand-alone humidifier comes fully assembled and tested for field installation. It automatically adds moisture into the cellar by the evaporation of water over a distribution pad.

Overview of the Wine Guardian Unit

Refer to illustrations on page 10

Cabinet – The cabinet is 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.

Evaporator Section – Wine cellar air is circulated through the evaporator section by a direct drive, permanently or lubricated motorized impellar blower. 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.

Electrical Controls –All solid state electronic controls are connected internally and/or externally through a phone cord-type connection. There is no need to open the chassis to access the factory mounted and wired control. All internal 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 systems are factory run-tested and checked for operational performance.

Internal Drain Trap – 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 capillary tube expansion device, a filter dryer, and a manual reset high pressure switch. See Refrigeration Illustration on page

Supply/return grilles – These are made of rugged ABS plastic and factory mounted to automatically seal to the chassis. Air is introduced through the sides and bottom and discharged through the front perforated section.

Directional Louvers – Two directional louvers are located within the evaporator supply air discharge opening on the Wine Guardian system and can be accessed by removal of the wine cellar side faceplate. The louvers are designed to be manually adjusted to direct air flow from side-to-side or straight on. The louvers can help direct cold air into the center of the wine cellar should the Throughthe-Wall system be mounted in a corner of the room.

Planning the Installation

Required Tools

Addressing Items in the Planning Process

√ Where to locate the system? It can be mounted flush with the racking or flush with the wall on the wine cellar side.

√ How to mount the system? A mounting kit is supplied.

√ Locate the electrical power outlet close to the system, in cellar or out . Do not use an extension cord!

√ Factory supplied power cord on condenser side of the system. It is preferred to be on the condenser side of the system, the cord can be moved to accomodate wine cellar side if need be.

√ Does the condenser heat exhaust need to be ducted away? An optional kit is avail- able.

√ Where to locate the thermostat, if remote interface control is ordered? Thermostat should be located mid point on a wall within the wine cellar. Provides suffficient access and exposure to airflow from the Wine Guardian system. The thermostat should not be located under shelving or within racking.

√ Where to run the overflow drain line? Run to a field supplied drain location or container

√ Are all the parts here to complete the installation? Installation sleeve, gasket , sealent, fasteners

Performing a Pre-installation Check

√ Check for the properly sized breaker as dictated by the system rating plate data.

√ 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.

Locating the System

Wine Guardian systems are typically installed at the users eye level for ease of operation. The Throughthe-Wall system discharges warm air from its condenser end so this should be considered when determining the location for the system. Locating the system adjacent to a mechanical room or in close proximity to an exterior wall may be required if ducting the warm condenser air is being considered.

The warmer condenser air can be ducted up to15 feet away.

Power Cord Location

As previously noted, the power cord is factory wired on the condenser side of the system. If you require the cord on the wine cellar side for plugging into an available outlet, this can be accomplished by removing the 3-wire leads (ground included) and moving the cord with connector to the opposite side control bracket and wire nutting the black and white wires to the factory supplied loads. The wires must have the terminations cut off and stripped first. Then screw the ground lead to the hole supplied in the control bracket.

You must then move the voltage switch in the opposite direction as from the factory to move the internal power to the cord on the wine cellar side.(See Illustrations)

Grilles

Factory supplied and installed for proper air intake and discharge for optimal system performance.

Mounting the System

Follow the steps on the following pages for installation of the Wine Guardian Through-the-Wall system a “new” wine cellar installation.

17

Step 1

Find wall stud locations. If both wine cellar side and finished basement side of walls have drywall already installed it is important to locate the wall studs in the area chosen to mount the Through-the-

Wall system. Use of any high quality stud finder is recommended for locating the center and edges of the wall studs on the wine cellar wall. Once located, the stud edges should be clearly marked prior to following Step 2 below.

Step 2

Preparing wall penetration for Installation Sleeve. Mark the penetration dimensions on the wall (wine cellar and finished basement side) at the desired mounting location for the Wine Guardian Throughthe-Wall system. Keep in mind the ideal height should be at eye level to the user. The unit controls should be reachable upon installation completion. The wall penetration should be no nore than 14-1/2” wide by 16-1/4” high stud-to-stud dimension so modifying stud locations is not required.

CAUTION


Ensure that the area chosen does not have electrical or plumbing interference within the wall or along the outside of the wall. Failure to do so could cause property damage or perosnal injury. If the wall does include electrical wiring or plumbing DO NOT CONTINUE. Contact a qualified electrician or plumber to relocate these services or choose an alternate location for mounting the WG system.

Step 3

Slide the EasyMount

TM

sleeve through the wall penetration so that the flanged area of the sleeve sits flush with the surface of the wall. Ensure the EasyMount TM sleeve is level and plumb prior to fastening to the existing studs.

IMPORTANT

The Installation Sleeve must be installed level within the wall opening to provide proper operation of the Wine Guardian system. Failure to do so may result in improper drainage, excessive ware, vibration and noise.

Caution


Flange side of the sleeve must be mounted on side of wall you intend to have the WG flush mounted.

Step 4

Fasten the EasyMount TM sleeve to the wall studs through the six (6) pre-drilled holes located on either side of the EasyMount

TM

sleeve. Starting at location (1) insert a wood screw into the pre-drilled hole and tighten the screw until it is snug. Do no over tighten. Continue to the number (2) Through (6) positions and tighten until all are snug. Do not over tighten. Once each screw has been installed repeat the progression (1) through (6) so that each screw is tight. Ensure screws are inserted flush with wall sleeve inside surface.

Step 5

Slide the Wine Guardian Through-the-Wall system through the EasyMount

TM sleeve to the desired depth.lease note the Through-the-Wall system must be slid so that the power cord side is last, not first, to enter the sleeve. Do not slide the system past the desired flush mounting point.

19

Step 6

Seal joint between EasyMount TM sleeve and Wine Guardian system on the flange side of system with bulb weather strip seal material provided, to ensure a tight seal and prevent the system from horizontal movement.

Installing the Condensate Overflow

Condensate generation is a natural by-product of air conditioning systems. The Wine Guardian cooling coils are designed with the understanding that optimal wine cellar humidity levels are between 55% RH and 70%RH. If the vapor barrier of the wine cellar is poorly constructed or excessive moisture is in the basement or surrounding area then the cooling coil may generate excessive amounts of moisture. The condensate will appear in the form of water at the cooling coil drain pan and eventually will travel to the board condensate removal system located below the compressor. The Wine Guardian system features an auxiliary drainport connection located at the condenser end of the system directly below the plastic face plate. In the event of excessive moisture we recommmend connecting the drainport as indicated below.

Installing the Drain Line

√ The drain line must extend from the system to an external drain or disposal site. Do not use drain tubing any smaller than 1/4 inch inside dimension on the system.

√ If no floor drain is available, use a bucket. Do not extend the drain below the rim of the bucket. Empty the bucket periodically.

Allow enough height for the drain line to function properly. If draining into a nearby sink, the system must be elevated higher than the rim of the sink in order for the water to drain by gravity. Install with a ¼ inch per linear foot of pitch. See Accessories and Optional Equipment section for informa- tion about the condensate pump.

Priming the Drain Trap

The internal drain trap primes itself automatically once the unit has run for a period of time and after the system cycles off. This is confirmed by water dripping from the drain.

Wiring the System for Power

WARNING

ELECTRICAL SHOCK HAZARD

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 system.

√ 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.

DO NOT:

√ DO NOT MODIFY THE PLUGS IN ANY WAY!

√ Do not use extension cords.

IMPORTANT

The electrical power supply must be 115 volt AC 1 phase 60 cycle, depending on the model of the system, and cannot vary more than +/- 4% or damage may occur to the system.

Plug the system into the wall outlet. Gently pull on the plug to make sure it is tight.

21

Electrical Plug Configuration

22

To comply with the UL STD 484 this system contains a factory supplied LCDI (leakage current detection interruptor) power cord, which specifies that single phase portable air conditioning units contain a porotection device to reduce the risk of an arc fault occuring in the power cord. These provide a reliable way to prevent the risk of fire due to a damaged power cord. They feature electronic detection to automatically cut off power to the unit when a current leakage condition is detected in the systems power cord.

Once power is shut off, the device will not be able to be reset until the unsafe current leakage situation is resolved. Power is restores by the “reset” button on the cord’s power head.

Control Options and Wiring

Each Wine Guardian system comes with a control mounted on front of system. It is wired at the factory for testing prior to shipment. Previously described in this manual.

Note

Keep the thermostat guide in a folder along with the Wine Guardian Manual for future reference.

Remote Thermostat (Optional)

A phone cord-style communication cable is required to connect back to port supplied on the main chassis. This may be factory supplied.

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 feet to 5 feet above the floor.

Remote Temperature/Humidity Sensor

Previously described operation. This is also connected to the Wine Guardian chassis via a phone cordstyle cable, which may be factory supplied.

All other settings are to remain as listed above.

Testing the Fan

Scroll through configurations settings to 17 for “On” or “Auto” operation. It is factory default to “Auto”.

• ON 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 or humidification.

Running the System

√ Check system to confirm the compressor is running. When the compressor is on, the system will blow cold air to the wine cellar and warm air from the condensor section.

√ Check for any unusual noise or vibration, such as clanking or rubbing.

Important: It is normal for the display to read a “high temperture” default alarm upon initial start-up while trying to pull the wine cellar down to operating conditions as factory default is set at 60 0 F and its likely the cellar may be above this condition upon initial start-up in a new application. The system will continue to cool until it gets within 2 % +/- of the set point.

Initially, the system may run continuously for several hours, up to a day or more, while it lowers the cellar temperature. Once the system reaches the set point temperature, it shuts off and starts to cycle on and off as it continues to lower the cellar temperature to the set point. The cellar air reaches set point before the bottles.

If the cellar temperature started at 75 0 F, the supply air temperature discharged from the system will probably be 15 to 20 0 F colder. As the cellar temperature decreases to 55 0 F, the supply temperature differential decreases 8 to 12 0 F colder.

Cycling the System

The fans continue to free-wheel for several minutes when the unit cycles off, if fan set to “auto” only. This is normal.

Regulating the Wine Cellar Temperature

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.

Changing the Air Flow Direction

The grilles furnished with Wine Guardian are single directional, but the wine cellar airflow can be directed horizontally manually by setting the louvers behind the plastic panel to desired direction. You must first remove the 2 screws in the bottom of the plastic front to remove the front to gain access to turn the air directions as desired.

Maintenance

General

WARNING

BEFORE PERFORMING MAINTENANCE ON THE SYSTEM, 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 removing end panels or cover.

CAUTION

SHARP EDGES

RISK OF SEROUS INJURY

Sharp edges are present on the fan wheels, housing, fins and coils.

Maintenance on Wine Guardian system 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 system.

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 system.

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 system may be required due to dust or dirt in the air stream.

28

Maintenance Schedule

Monthly

(or quarterly depending on experience with individual cellar)

√ Check for noise or vibration.

√ Check for short-cycling of the system - a turning on and off of the compressor unit more than eight (8) times/hour.

Yearly

(in addition to monthly)

√ Check evaporator and condenser coils for dirt – use a vacuum with a brush attachment to clean the coils.

√ 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 system by vacuuming or wiping it down.

√ Check for loose insulation, fasteners, gaskets or connections.

√ Check the wiring connections and integrity of cords.

√ Examine condenser duct (if option is used) for any cracks or breach.

High Pressure Switch has Shut the System Down

Every Wine Guardian system 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 Solution

Head Pressure in unit is too high because Remove the obstruction in the duct or grille or an obstruction is restricting air flow through. clean the coil. Then restart the system after

resetting the high pressure switch.

Instructions to Reset High Pressure Switch

√ Turn the Wine Guardian system off at the control (local or remote)

√ Locate the high pressure reset switch which is located within the air outlet section at the condenser side of the system. The switch has a red push button and is accessible by removing the plastic end cover.

√ Remove the condenser side plastic access panel.

√ Locate the high pressure switch reset in the panel behind the plastic access panel.

√ Push in the button until it locks into position.

√ Place the condenser side plastic panel back on.

√ Restart the unit at the local (or remote interface).

Alarm Annunciation

When an alarm condition occurs, the control will flash the backlight on the display in addition to annunciating the actual fault on the screen. The user can make the backlight flashing stop by pressing a button on the local user interface. However, the alarm annunciation will not actually clear on the display until the fault is corrected.
