General Description

View the Overview Illustration on page 8 for details. The Wine Guardian cooling unit is a professional grade American 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.

All Wine Guardian 50Hz units carry the CE mark. Each unit is furnished with a sealed, CEapproved 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.

The water-cooled Wine Guardian system requires cooling water to be piped to the unit for proper operation. The cooling water absorbs the refrigerant heat through the unit’s water-cooled condenser coil. Warm water is then directed out of the unit back to the cooling water system or to a drain.

IMPORTANT

The air exhaust from the condenser fan is hot and will be 15 to 18 degrees C 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 contaminant  A sight glass to observe the level of refrigerant  An automatic low pressure switch on the discharge to protect the compressor form high

pressures

 The unit uses only environmentally friendly refrigerant F-134a  A built-in condensate drain trap. No external trap is required.

The Wine Guardian meets or exceeds its rated capacities for total watts and cubic litres per second 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 1.6mm 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 manufacturer’s 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. All external controls are digital and proprietary to Wine Guardian products. Only approved communication cable and Wine Guardian controllers are suitable for proper system operation.

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 valve 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 7.3 metre 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 Wine 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 50°C. 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 outside. It requires a separate 220/240 volt electrical outlet.

to pump the water to a sink or

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 humidity 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.

CAREFULLY FOLLOW THE INSTALLATIONS INSTRUCTIONS INCLUDED WITH THE HUMIDIFIER. REFER TO THE

INSTRUCTIONS CONTAINED IN THE BOX FOR THE HUMIDISTAT.

CAUTION

Overview of the Wine Guardian Unit

Refer to illustrations on page 8

Cabinet

for corrosion protection and an attractive, maintenance free appearance. Areas in contact with cold temperatures are lined with insulation to prevent condensation.

–

The cabinet and access doors are constructed of aluminum with a powder coated finish

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. 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 25mm 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 manual 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.

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, in cellar or out. 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?

 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?

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 7.5 metres is recommended. If longer runs are needed use more than one supply opening to reduce the airflow in each duct by 1/2. See Recommended Flexible Ductwork Sizing Chart on page 30.

Provide a 1 metre 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 25 or 50mm 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.

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-proofed 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 frame with a plywood surface to keep it away from water. Allow adequate space for the external drain.

Wall Mounting

If the unit is mounted 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.

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 +/- 6mm end-to-end and +/- 3mm 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 6mm 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 12mm inside dimension on the unit.

 Splice the drain extension onto the drain outlet with a sort piece of 12mm copper tubing and secure with claps.

 If not 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 10mm per linear metre. 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.

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.

Installing the Thermostat and Communication Cable

The Wine Guardian Remote Interface Controller is a combination temperature and humidity controller with single stage cooling, heating and humidifier control. Each Wine Guardian unit is supplied with a Remote Interface Controller and 15 meters feet of communication cable. It is wired at the factory for testing prior to shipment.

In most applications the Remote Interface Controller will be mounted within the wine cellar. The remote interface controller can also be

mounted directly outside of the wine cellar or in any other room of the home or building. When mounted outside of the wine cellar, a remote sensor kit must be purchased and installed within the wine cellar. See below for remote sensor installation details.

IMPORTANT

Wine Guardian units are supplied with 15 meters of Cat 3, 6-wire twisted pair

communication cable with RJ-11 connectors. Failure to use this type of communication

cable WILL cause product damage and WILL void any equipment warranty.

Installation instructions should be followed CAREFULLY as improper splicing and/or

joining of twisted pair cables can cause equipment failure.

Mounting the Remote Interface Controller

. Disconnect the communication cable from the side of

the Wine Guardian unit and the Remote Interface Controller.

a) Install the communication cable within the wall

and/or ceiling structure of the wine cellar to the

desired controller mounting location.

b) Mount the remote interface controller on a solid

surface away from doors, corners, air outlets, drafts or

heat generating equipment. Do not mount the Remote

Interface Controller directly on an outside wall or wall

adjacent to a boiler room.

2. Remove the back plate of the controller and mark the mounting points at the desired location. (Fig. 2)

a) Mark the location of the communication

cable connection as this area will require sufficient clearance for instance, a 3.8cm hole in the wall for flush mounting of the back plate. (Fig. 3)

3. Drill two (2) .32cm holes and insert anchors (provided) within the mounting surface. Anchors may not be required if securing to a wall stud or racking system.

4. Plug in the communication cable to the back of the Remote Interface Controller backing plate. (Fig.4)

a) Attach backing plate to wall using the two screws

provided with the system. (Fig.5)

5. Re-install plastic face plate on to backing plate.

6. Re-attach the communication cable to the side of the Wine Guardian cooling unit. (Fig.6)

The Remote Sensor is a combination temperature and humidity sensor only. It is designed to be mounted within the wine cellar and can be used in combination with the Remote Interface Controller or up to three additional Remote Sensors to read and control multiple areas within the wine cellar.

Installation of the Wine Guardian Remote Sensor

Mounting the remote sensor

1. Disconnect the communication cable from the side of the Wine Guardian unit and the remote sensor. Install the communication cable within the wall and/or ceiling structure of the wine cellar to the desired controller mounting location.

A splitter device has been supplied within the Remote Sensor kit. The splitter device must be mounted at the WG unit as shown. DO NOT mount the splitter device at the back of the Remote Interface Controller or to the back of the Remote Sensor as this WILL cause component or system damage.

2. Mount the Remote Sensor on a solid surface away from doors, corners, air outlets, drafts or heat generating equipment. Do not mount the Remote Sensor directly on an outside wall or wall adjacent to a boiler room. Use a piece of foam insulation behind the sensor to insulate it from a hot or cold surface. The recommended height is 1.2 to 1.5 meters above the finished floor.

Remove the sensor cover plate by removing the two allen head screws at the top of the cover using the allen head wrench provided in the kit.(Fig.2) Mark the mounting points at the desired location within the wine cellar. Also mark the location of the communication cable connection as this area will require sufficient clearance, for instance

Joining Communication Cable

Important Wine Guardian cooling systems are supplied with 15 meters of 6 wire, Cat 3 twisted pair communication cable with RJ11 type connectors. Caution must be taken when connecting two lengths of communication cable (splicing) to ensure uniform wire color before and after splice. An RJ11 Modular 6 wire STRAIGHT THROUGH type coupler is the ONLY coupler approved for splicing Wine Guardian twisted pair communication cable.

Jumper position 1

Jumper position 2

If using multiple Remote Temperature/Humidity sensors in your application, refer to the photos showing the need to change the jumper locations internal to the control board on each remote sensor (up to 3 maximum).

For the control to average all of the sensors utilized (if more than one), the jumper must be in different positions on the pins.

As you can see, there are three pin settings. To access the jumper:

1. Remove the two-set screws holding on the plastic cover. This procedure allows the control to go to each remote sensor in sequence to average. Failure to perform this procedure will result in the system reading only one sensor and not the average of multiple sensors.

NOTE: If multiple sensors control the WG unit, change factory default in configuration setting 10 to “averaging.” You will need access code from Air Innovations service to use in configuration 8 to reach configuration 10
