The PRO Split System is a professional grade, American-manufactured, split two-piece climate control unit designed specifically for the storage of wine at wine room temperatures. It is designed for easy installation and operation. Wine Guardian PRO Split System uses 24 volt controls and R-134a refrigerant. The entire PRO Split System fan coil and condensing unit sections are tested at the factory. All components are of a high quality standard commercial grade. The entire system is approved by ETL according to UL 1995 and CSA safety standards. All wiring complies with NEC. Each PRO Split System fan coil section is furnished with a sealed, UL-approved power cord and plug.

The Wine Guardian PRO Split System Contains

1. A Wine Guardian PRO Split System Fan Coil Unit with:

 A thermal expansion valve to control the flow of refrigerant into the evaporator coil

Design and specifications are subject to change without notice

 A built-in condensate drain trap. No external trap is required.  A removable control panel for ease of service  Supply duct collar  Return duct collar  24 volt terminal strip for connection to standard thermostats/humidistats

2. A Condensing Unit with:

PRO Split System Fan Coil Unit

The PRO Split System fan coil unit meets its rated capacities for total BTU/H and CFM at design room conditions and external static pressures. The fan coil unit is capable of rated CFM against the static pressure imposed by recommended ductwork. The fan is a motorized impeller type, statically and dynamically balanced, and uses permanently lubricated direct drive motors requiring no maintenance.

The PRO Split System fan coil section operates as 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 through one of five openings. Optional heating coils are located between the cooling coil and the fan. These coils heat the air to prevent low temperatures in the wine room.

All exterior framing of the PRO Split System is powder coated 0.063 inch gauge aluminum to prevent rust and corrosion. All coils are aluminum tubes, aluminum fins to protect against premature corrosion. The unit uses an external drain to remove excess moisture and not reintroduce it into the room or ambient space. Removable, multiple access doors are provided to facilitate cleaning and maintenance, duct connections, and access to components and wiring. The fan coil has at least five discharge outlets to facilitate custom installations.

Each unit is provided with a 24 volt terminal strip for connection to most standard 24 volt thermostats or humidistats. A thermostat is not provided as standard equipment.

Electrical Controls

The main electrical control components are located on a separate pane l accessible through a side door pane l or by removal of the on/off panel from the system chassis.

All wiring is in accordance with the NEC. Wires are

numbered and color coded to match the wiring diagrams.

Electric power is supplied by a single factory-furnished cord and plug.

Condensing Unit

Compressors are rotary, self-lubricating, permanently sealed, hermetic reciprocating-type compressors, with internal overload protection and capacitor start. They include a minimum of 20 months manufacturer’s warranty and an optional five-year warranty. Compressors are mounted on rubber-inshear isolators to reduce noise and vibration. Additional features include a liquid line filter drier, Head Master Controls, a liquid line receiver, refrigerant sight glass, manual reset high pressure switch and auto reset low pressure switch. Each unit is housed in a painted aluminum enclosure suitable for outdoor installation. The outdoor enclosure has an integral fan for air movement across the condenser coil, pre-drilled penetrations for electrical connections and external king valves for ease of refrigerant piping connections.

The air exhaust from the c ondens ing uni t is hot and will be 25 to 35 degrees F above the entering

temperature. The con densing units a re rate d for a maxi mum tempe rature of 115 degrees F. The

condensing uni ts sho uld be installed in a well-ventilated area to ensure proper air flow across the

condenser coil and to limit short cycling.

IMPORTANT

Accessories and Optional Eq u ipment

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.

Duct Collars and Flexible Ducts

Ducting for the Wine Guardian PRO Split System is sold in kits by size for each unit. Each kit contains two adapter collars, one 25-foot length of round flexible duct and two straps. The number of duct kits needed depends on the wine room layout and application. The size of the kit depends on the model Wine Guardian PRO Split System selected. Follow installation instructions carefully. Poorly or incorrectly installed ducts can degrade the performance of your unit dramatically.

Extended Compressor Warranty

The Wine Guardian PRO Split System 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 – Standard on all Wine Guardian PRO Split Systems

A factory-installed low ambient option is available that makes the Wine Guardian PRO Split System capable of exposure to low ambient temperatures. This feature controls the condenser fan operation based on head pressure and heats the compressor oil reservoir. The low ambient option is recommended whenever the condenser section is exposed to air temperatures below 40 degrees F. to a minimum of 20 degrees F.

Extreme Low Ambient Option

A factory installed extreme low ambient option is available that makes the Wine Guardian Pro Split System capable of exposure to temperatures as low as -20 Deg F (-29 Deg C) . This feature includes the addition of a receiver heater, an adjustable timer for low pressure cutout, fan cycling switch, check valve and thermostat. The Extreme Low Ambient Option is recommended whenever the condenser section is exposed to air temperatures below 20 Deg F (-7 Deg C) to a minimum of -20 Deg F (-29 Deg C).

CAUTION

RISK OF PERSONAL INJURY OR DAMAGE TO EQUIPMENT

Improper installation may result in the equipment malfunctioning and a safety hazard. Read all

of the installation instructions be fore i nstal li ng the Wi ne Guardia n PRO Split System.

Planning the Installation

Installation of residential and commercial split systems must be performed by qualified

service technicians with proper training in the installation, start up, service, and repair of

these systems. Certification to handle refrigerants is also required.

Addressing Items in the Planning Process

 Where to locate the fan coil unit? Should it be built into the wine room or

mounted remote and ducted into the room?

 How to mount the fan coil 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!

IMPORTANT

 Locate the condensing unit in a clean, dry and well-ventilated area.  Where to locate the remote interface controller and/or remote sensors?  Where to run the drain line?  Are all the parts available to complete the installation?

Performing a Pre-installation Check

 Check for the proper installation of the electrical plug configuration.  Check for the properly sized breakers for both the condensing unit and fan coil

section.

 Is the room 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 units for service and repair?

Installing the Fan Coil Unit

Wine Guardian PRO Split System fan coil units are typically installed indoors located near the room to minimize the duct runs. Each unit is provided with one entering or return air inlet and five possible supply air outlets. A maximum cumulative total length of flexible ductwork, for both supply and return ducts (including bends) of 25 feet is recommended. If longer runs are needed, use more than one supply opening to reduce the airflow in each duct by one-half, or install rigid ductwork that is typically less restrictive. Do not exceed 50 feet of total ductwork without using of booster fans. See Recommended Flexible Ductwork Sizing Chart on page

35.

Provide a three-foot clearance arou nd the unit for removal of ductwork, or access for unit maintenance. If the humidifier is used, provide access space in front of it for service. (See separate humidifier manual.)

The fan coil unit can be located either above, or below the condensing unit in height. Wine Guardian PRO Split System strongly suggests that any height difference be kept as minimal as possible.

The fan coil unit is equipped with an On/Off switch, 24 volt terminal strip and a humidifier

communication port for connection to an optional humidifier.

CAUTION

System.

NOTE:

Review Fig. 1 through Fig. 4 on the following pages before mounting the unit.

Floor Mounting

Mount the Wine Guardian PRO Split System fan coil on a plywood surface at least 12 inches above the floor to keep it away from water. Allow adequate space for the external drain.

Wall Mounting

If the unit is mounted onto a wall, provide adequate support on both ends of the unit to accommodate the weight of the system. Use knee braces to transfer the load of the unit to the wall. A shelf can be constructed to support the unit or a wall mount kit can be purchased through a Wine Guardian PRO Split System distributor.

Ceiling Mounting

Construct a structurally sound, level platform to place the unit on when hanging it from the ceiling joists. The Wine Guardian PRO Split System is NOT designed to be suspended from the top of the unit; it must be supported from the bottom. Angle brackets are available as an option for these types of applications. Place the unit on a platform to ensure that the unit is supported on all four 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 plus or minus one-quarter inch end-to-end and plus or minus one-either inch side-to-side for proper operation. Locate the unit as close to the wine room as possible to reduce the length of the duct runs. If possible, use short and straight ducting on all ductwork runs.

Typical Mounting Arrangements

The following illustrations are suggested mounting arrangements. These illustrations are not intended to be complete and detailed installation drawings. For questions or help regarding installation, contact a Wine Guardian PRO Split System distributor or email (info@wineguardian.com) a sketch of the proposed area where the unit is to be installed.

Handling and Installation

1) Mount unit on solid, level surface.

2) Allow sufficient space for access to unit and accessories.

3) Provide proper electrical service.

4) Provide water to humidifier.

5) Install drain line with proper pitch.

Duct Collars

One inlet duct collar and one evaporator outlet are supplied with each fan coil unit as standard equipment from the factory. The duct collars are removable. The return air, or inlet duct collar must connect to the return air outlet from the wine room. Any of the five supply air outlets on the unit can be used for the ductwork to the supply grille(s) inside the wine room. The factory installed supply duct collar can be relocated to any of the five openings as needed.

Use ductwork to connect the unit to the supply and return outlets in the wine room. Use only insulated ductwork to minimize cooling loses, prevent sweating, and to reduce noise.

NOTE: Do not exceed a total of 25 feet for each length of ductwork run (supply and return).

RISK OF DAMAGE TO EQUI PMEN T

Avoid crimping the flex i ble ducts. This c hokes down the inside area and reduces the airflow,

causing the u nit to operate erratically.

Be sure all ducts and surface in contact wit h t he air fl ow are i nsulate d

and have a vapor barrier on the outside surface.

NOTE: Uninsulated ducts and surfaces cause bare exposed metal surfaces to sweat, further degradation of the insulation and a loss of equipment cooling capacity.

Location of Su pply and Return Grilles

Locate supply and return grilles inside the room 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.

 Do not locate the supply or return air grille where there are blocked by bottles, boxes or

cases.

 Do not locate the supply air grille where it blows directly on the remote interface

controller.

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 a 90-degree 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 11 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 PRO Split System 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.

NOTE: 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.

Reducing Noise from the Unit

Consider noise when locating the unit close to the room or an adjacent occupied space. A piece of one – or two-inch dense rubber or Styrofoam with foil face in between the unit and the wall absorbs and reduces the noise from the unit. In case of air noise use larger 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, place a rubber pad under the unit to reduce vibration transmission.

Installing the Condensate Drain Connection

The Wine Guardian PRO Split System provides dehumidification for the inside of the wine room. It cools the air down to the dew point corresponding to the temperature setpoint of the remote interface controller. If the vapor barrier of the wine room is poorly constructed or excess moisture is in the basement, the unit may remove excessi ve am ounts of moisture from the wine room. The moisture appears in the condensate drain of the unit.

NOTE: the basement so as to not overload your Wine Guardian PRO Split System.

If moisture becomes excessive, install a room type dehumidifier to dehumidify

Installing the Drain Line

 The drain line must extend from the unit to an external drain or disposal point. Do not use drain tubing any smaller than one-half inch inside dimension on the unit.

 Slide the clear plastic drain tube onto the barbed fitting at the fan-coil unit and secure with a worm gear type clamp.

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

The Wine Guardian PRO Split System 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 drain line.

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 one-quarter inch per linear foot of pitch. Do not tie the condensate drain line directly into the sanitary sewer system. See Accessories and Optional Equipment on page 6 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 can be confirmed by water dripping from the drain.

Installing the Condensing Unit

• Condensing units are factory assembled with a sheet metal outdoor hood for protection

from the elements.

• A minimum of 12 inches is required around the perimeter of the condensing unit for

proper airflow across the coil, and to provide an adequate discharge airflow path through the louver section. Any obstructions to this airflow will result in a decrease in performance, and possibly premature failure due to a buildup of high pressure within the system.

• The condensing unit is designed to operate in ambient temperatures ranging from 20

degrees F to 115 degrees F, as it is supplied with many standard features to assist full operation in this wide range.

• Mount the condensing unit above normal snowfall levels, so as to allow uninhibited winter

operation. A build up of snow or any obstruction to airflow will result in a decrease in performance and possible premature failure due to an increasingly high pressure within the system.

Installation of Interconnecting Refrigerant Lines (Suction and Liquid)

NOTE: The interconnecting copper refrigerant lines shall be supplied by the installer. The larger suction line must be fully insulated along its complete length from condensing unit to fan coil unit. There is a factory-installed liquid line filter-drier inside the condensing unit; therefore no additional drier is needed for proper operation. A liquid line moisture/sight glass is factory installed in the condensing unit to assist in monitoring the refrigerant charge, and the state of the refrigerant in the system.

• Keep horizontal and vertical distances between the indoor and outdoor section as close as

possible to minimize refrigerant charge required. This will reduce system issues related to oil management that can impair performance and jeopardize the compressor’s lubrication.

• Provide a one-inch pitch in suction and liquid line toward the evaporator for every 10 feet

of run to prevent any refrigerant that condenses in the suction line from flowing to the compressor when the unit is off. These two lines can be routed together and wrapped together, as long as the suction line is fully insulated as previously directed.

• Suction line riser traps are not required if the riser is properly sized to maintain refrigerant

velocity. Adding a trap will only increase pressure drop.

• Prevent dips, sags, or other low spots that will trap refrigerant oil, which is an issue

especially with long horizontal runs. Use hard refrigerant copper for longer horizontal runs to prevent potential oil return problems. (see sample piping chart on page 34)

• When sweat connections are made in the connecting lines, be sure that the inside of the

• that compressor suction and discharge valves should be open to atmosphere no longer than

15 minutes. Compressors with POE (polyolester) oil will quickly become contaminated when opened to atmosphere. On any installation, the use of a suction line filter, liquid line filter drier and moisture indicator is recommended. If the suction line is larger than onequarter inch, a vibration eliminator should be installed close to the motor compressor in a

horizontal parallel to the compressor, crankshaft or in a vertical position 90 degrees to

Leak Checking and Evacuation Process

WARNING

ALL COMPONENTS CHARGED WITH DRY AIR MUST BE EVACULATED

BEFORE CHARGING WITH REFRIGERANT

• Purge the dry air charge from the unit by opening the liquid line shut-off valve or

removing the liquid line outlet fitting or plug, whichever is applicable for your particular unit. Connect the suction and liquid lines to the unit.

• Pressurize and leak test the entire system including the condensing unit, evaporator and all

connecting tubing, fittings, and brazed joints using the intended operating refrigerant for leak testing. A pressure equal to the low side test pressure marked on the unit nameplate is recommended for leak testing. Repair any leaks found. Connect a good vacuum pump to both the low and high side evacuation valves (if provided) with copper tube or high vacuum tube (three-eighths inch inside diameter minimum) and draw a deep vacuum of at least 15pp microns. Do not use the motor compressor to pull a vacuum and do not operate the motor compressor in a vacuum. Break the vacuum with nitrogen.

• Evacuate the system to hold at 500 microns and break the vacuum with refrigerant.

Remove the vacuum pump. The system is now ready for charging. Charge the system with the correct amount of refrigerant and mark the amount, with a ballpoint pen, in the space provided on the unit nameplate.

Wiring

NOTE: When charging through the suction service valve the refrigerant should be charged in vapor form. NEVER CHARGE IN LIQUID FORM. Refrigerant should always be charged through a dryer. Charging in liquid form may damage the valve plate assembly as well as scrub the oil out of the compressor bearings

WARNING

NON-AZEOTROPES MUST BE CHARGED IN THE LIQUID PHASE ONLY. TO AVOID COMPRESSOR

DAMAGE, LIQUID MUST ALWAYS BE CHARGED INTO THE HIGH SIDE OR INTO AN

ACCUMULATOR.

NOTE: Be sure there is not an overcharge of refrigerant. An overcharge might permit liquid refrigerant to enter the motor compressor and damage the valves, rods, pistons, etc.

• Wire the system as per the supplied wiring schematic found on pages 15 through 24 of

this manual.

• The fan coil unit is powered through a factory-supplied power cord, but you will need

to run 24 volt power wires from the two position terminal block to the condensing unit. This can be typical 24 volt thermostat cable or 18 gauge insulated wire. (see Fig.1 on the following page)

Fig. 1

Low

24 volt

Voltage Block

On/Off switch

• The condensing unit needs to be hard-wired for the rated high voltage to be brought to

the factory-installed contactor in chassis cabinet to the line side (L1 & L2) of the contactor. Use table 1 to identify the minimum recommended AWG, USE COPPER WIRE ONLY. Run a ground lead to be connected to the condensing unit Ground lead/LUG. There is a separate ground lug for the condensing unit internal components (See Fig 2). The load side of the factory-installed contactor will be factory-wired. •

• Turn on power to the condensing unit 24 hours prior to system start-up to allow

crankcase heater to warm up compressor crankcase.

Refrigerant Charging

NOTE: The SP25, SP50, SP88 and SP200 systems utilize a Headmaster control valve to control head pressure at low ambient applications, therefore require a specific initial charging procedure as outlined below.

Determining the amount of charge – When “refrigerant side” head pressure control is

utilized on a system, one of the most important factors is determining the total system refrigerant charge. While on most packaged units the amount of charge is listed on the unit, the required charge for a field built-up system cannot be listed by the manufacturer. Charge is usually added when the system is started up until “proper” system performance is reached. However, this is not satisfactory and if the system is to function properly year-round, the correct amount of extra charge must be calculated ahead of time.

Procedures for Charging System with Head Pressure Control

NOTE: When charging any system with head pressure control the outdoor ambient temperature must be known.

Charging of Systems with Head Pressure Control in ambients above 70 degrees F (After normal evacuation procedures):

1. Connect refrigerant cylinder to a charging or gauge port on the receiver outlet valve.

2. Open the receiver valve approximately one-halfway (so receiver and liquid line are connected

to charging or gauge port).

3. Charge liquid refrigerant into the high side of the system. Weighing the charge is

recommended.

4. Remove the refrigerant drum and connect it to the suction side of the compressor.

5. Charge refrigerant vapor into the low side. Do not allow liquid refrigerant into the low side.

6. Start the system.

7. Observe sight glass (at receiver outlet) to see if system is filling with refrigerant for normal

refrigeration cycle.

CAUTION

BUBBLES IN THE SIGHT GLASS CAN BE CAUSED BY FLASHING DUE TO PRESSURE DROP FROM PIPE

OR ACCESSORY LOSSES, ETC.

8. If the Sight glass shows bubbles, more refrigerant may be required, while allowing sufficient

time for the refrigerant to stabilize and clear the Sight glass. Use supplied information on the following pages for proper final charge.

Charging of Systems with Sporlan Head Pressure Control in ambient temperature below 70 degrees F (After normal evacuation procedures):

NOTE: When charging in ambient below 70 Deg. F the procedure is very critical. Be sure to adhere to the following steps. Failure to do so will result in overcharging the system.

1. Follow instructions 1 through 7 above.

2. If the valve setting is correct for the system being charged, it is quite likely that some

refrigerant will be backed up into the condenser and the Sight glass will indicate bubbles in the liquid line.

3. Add more refrigerant, while allowing sufficient time for the refrigerant to stabilize and clear

the Sight glass. Use supplied information on the following pages for proper final charge.

4. At this point the system is correctly charged for this type of head pressure control at the

ambient temperature that exists while the charging procedure is taking place.

5. If the system is designed to operate at ambient below the ambient that exits during charging,

additional charge may have to be added now.

Since good system performance during low ambient operation depends on proper refrigerant charge, it is very important that this phase of the installation procedure be done carefully. Many times, poor system performance will be due to too little or too much charge. And in many cases, this will be the last item suspected.

With the system started

• After following instructions on the previous page on initial Charging for Systems with Head

Pressure Control, with refrigerant tank now connected to suction line (low side) port to add remaining charge in a gas state, refer to the provided charts for proper system operating points as equated to ambient temperature with wine room at normal conditions of 57 degrees F / 55%RH. Refer to Split Systems Operations chart on page 39 for system pressures, sub-cooling, and superheat values to allow you to charge your system correctly.

• In addition to using the charts provided, there is a liquid line moisture/sight glass located in the

condensing (outdoor) unit that will assist you in knowing that you have sufficiently charge your system, HOWEVER a full sight glass or a glass with bubbles does not necessarily mean you are properly charged, or undercharged. There may be other factors affecting sight glass, so do not charge by sight glass method only. A full sight glass- matched with proper system pressures, sub-cooling, and superheat values is the proper method for confirming that the system charge is correct for your application.

If you are not sure how to measure superheat or sub-cooling:

Superheat

• Get an accurate suction line temperature on the suction line as close to the compressor inlet as

possible. At same time, attach a compound pressure gauge set to the system so as to read the low side suction pressure at the suction service valve port (back seated valve stem to allow unrestricted refrigerant flow from evaporator back to the compressor). Convert suction pressure to a saturated temperature as derived from a pressure/temperature chart. Since the suction line temperature is the higher value, subtract the saturated temperature from it to derive your superheat. If your wine room is already at specified conditions (e.g., 57 degrees F, 55% RH), and if your superheat is very low, or zero, you may have overcharged your system.

Sub-Cooling

• With your compound pressure gauge set still installed with the high side connect to the valve

port on the liquid receiver (back seated valve stem to allow un-restricted refrigerant flow from condenser to evaporator). Convert this liquid pressure to a saturated temperature from pressure/temperature chart. Next, obtain your liquid line temperature by getting an accurate reading on the liquid line BEFORE the TXV expansion on the indoor side. Obtain this temperature entering the evaporator unit. Subtract the liquid line temperature from the saturated liquid temperature to derive the system sub-cooling.

When comparing your high side system pressure to supplied charts below, refer to the liquid line pressure.

To give you an idea on how much R134A refrigerant charge you may require to reach full charge for your given interconnecting line length, see the very general guidelines below based on liquid line size:

SP25, SP50 1/4” OD ~ .50 ounce/foot SP88, SP200 3/8” OD ~ 1.0 ounce/foot

**Based on factory testing using 25 feet of interconnected piping

SP25 = 16 ounce total charge SP50 = 16 ounce total charge SP88 = 16 ounce total charge SP200 = 16 ounce total charge

Replace all panels that were removed during installation. Check that all of the openings in the unit are covered with a blank panel, a ductwork connection or a grille.

CAUTION

RISK 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 compressor short cycling.

Testing the Fan

Refer to thermostat manufactures instructions on how to change the fan settings from ON 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,

heating, or the 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 room temperature. Once the unit reaches the setpoint temperature, it shuts off and starts to cycle on and off as it continues to lower the bottle temperature to the setpoint. The room air reaches set point before the bottles. If the room temperature started at 75 degrees the supply air temperature discharged from the unit will probably be 15 degrees to 20 degrees colder. As the room temperature decreases to 55 degrees, the supply temperature differential decreases 8 to 12 degrees colder.

Cycling the Unit

The fans continue to free-wheel for several minutes when the unit cycles off. This is normal. The unit is furnished with a low ambient control, so 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

A 24-volt thermostat/humidistat is not included with the WG Pro Split System and is the responsibility of the purchaser to provide. Please refer to the Operations Manual for your 24-volt thermostat/humidistat for set up and operation.

Regulating the Wine Room Temperature

Wine rooms have a natural temperature gradient of approximately 5 to 10 degrees between floor and ceiling. To increase or decrease the temperature in various zones, change the air flow patterns.

To keep the entire wine room 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 Room Temperature, place thermometers in various locations in the room to monitor the temperature zones. Change the temperature in various zones by shifting the air flow patterns.

Changing the Air Flow Direction

The optional grilles furnished with Wine Guardian PRO Split System are single directional. Rotate the grilles to change the direction of the air flow.

When using multiple supply ductwork, it is necessary to 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.

RISK OF SEROUS INJURY

SHARP EDGES ARE PRESENT ON THE FAN WHEELS, HOUSING, FINS AND COILS.

WARNING

DANGER

CAUTION

SHARP EDGES

NOTE: Maintenance on Wine Guardian PRO Split System requires working with high voltage a n d s hee t me tal w it h poss i ble s ha rp e dge s . 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.

EXPOSURE TO MICROBIAL GROWTH (MOLD) CAN CAUSE SERIOUS HEALTH PROBLEMS

CAUTION

NOTE: 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 PRO Split System 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.

SHARP EDGES RISK OF SERIOUS INJURY

SHARP EDGES ARE PRESENT ON THE FINS AND COILS.

CAUTION

Cleaning the Condensate Drain S ys tem

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 duct on the evaporator inlet.

3. 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 or duct collar.

7. Plug in the unit and restart.

Cleaning the Hum idifier (optional)

If the unit was furnished with a humidifier it requires periodic maintenance. Follow the

instructions in the humidifier guide.

Heating Coil Option

The heating coil 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 remote interface controller. Since the remote interface controller 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 to HEAT and set the temperature above the room temperature. The supply air temperature should start to rise above the return air temperature.

Maintenance Schedule

Monthly

(or quarterly depending on experience with individual room)

 Check 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 eight times/hour.

Yearly

(in addition to monthly)

 Check evaporator and condensing unit 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 unit by vacuuming or wiping it

down.

 Check for loose insulation, fasteners, gaskets or connections.  Check the wiring connections and integrity or cords.  Examine ducts for any cracks or breach.  Check fan and solenoid on humidifier.  Replace humidifier pad (if used).

High Pressure Switch has Shut the Unit Down

Every Wine Guardian PRO Split 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 becoming too high.

Possible Cause Solution

Head pressure in unit is too high because Remove the obstruction at the condensing unit or an obstruction is restricting air flow clean the condenser coil. Then restart the unit after resetting the using the high pressure switch.

Instructions to Reset High Pressu r e Switch

1. Remove the top and side access panels at the condensing unit

2. Locate the high pressure switch near the compressor

3. Push in the reset button until it locks into position.

4. Re-install top and side access panels
