Moving Parts Hazards The motor and blower must be disconnected prior to opening access panels. The motor can start automatically. Disconnect all power and control circuits prior to servicing to avoid serious injuries or possible dismemberment. The fans are free-wheeling after the power is disconnected. Allow the fans to stop completely before servicing the unit to avoid cuts or dismemberment. Rotating fan blades are present in the Wine Guardian unit.
Do not remove access panels until fan impellers have completely stopped. Pressure developed by moving impellers can cause excessive force against the access panels. Fan impellers continue to turn (free-wheel) after the power is shut off. CAUTION Clean only with a dry cloth. Never pressurize equipment above specified test pressure. See Wine Guardian Specification Sheet Do not use the Wine Guardian near water. Do not block any supply or return air register or duct.
Installation WARNING SHARP EDGES RISK OF SERIOUS INJURY SHARP EDGES ARE PRESENT INSIDE THE WINE GUARDIAN SYSTEM Pre-installation Test Test the system before installing it to check for non-visible shipping damage. To test the system: Set the system on the floor or a sturdy level surface. Plug in the system. Press the on/off switch and check that the control illuminates. This indicates the system has power. The built-in timer prevents short cycling and keeps the system from turning on right away.
WARNING RISK OF PERSONAL INJURY OR DAMAGE TO EQUIPMENT Modification to the equipment may cause injury or damage to the equipment . DANGER This equipment is heavy. Place the unit on the floor or on a level and stable surface that can support the full weight of the unit. Do not modify the equipment, it may cause damage to the equipment and will void the warranty. Never place anything on top of the unit. Never block or cover any of the openings or outlets to the unit.
Planning the Installation Addressing Items in the Planning Process Where to locate the unit? Should it be built into the wall or mounted remotely 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.
Grilles One grille is provided on the condenser outlet. The grille is removable and can be replaced with a duct collar should warm air need to be ducted away from the mounting area. Additional grilles can be purchased as an option and 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.
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 page 43 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.
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 one-half inch inside dimension on the unit. Splice the drain extension onto the drain outlet with a sort piece of one-half inch copper tubing and secure with claps. If no drain is available, use a bucket. Do not extend the drain below the rim of the bucket. Empty the bucket periodically. The Wine Guardian unit is provided with a built-in drain trap.
Sample serial plate D025 DO NOT: DO NOT MODIFY THE PLUGS IN ANY WAY! Do not use extension cords. IMPORTANT The electrical power supply must be either 115 volt or 230 volt AC, 1 phase, 60 cycle, depending on the model of the unit, and cannot vary more than plus or minus 4% or damage may occur to the unit. Plug the unit into the wall outlet. Gently pull on the plug to make sure it is tight. Fig.
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 50 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.
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 1½ inch hole in the wall for flush mounting of the back plate. (Fig. 3) Fig. 2 3. Drill two one-eighth inch holes and insert anchors (provided within the mounting surface. Anchors may not be required if securing to a wall stud or racking system. 4.

Installing the Ductwork and Grilles Use ductwork to connect the unit to the supply and return outlets in the wine cellar. Use only insulated ductwork to minimize cooling loses, prevent sweating, and to reduce noise. Use ductwork on the condenser section to redirect or absorb sound, to bring in outside air to the unit inlet, and/or to exhaust the hot air out of the ambient space. NOTE: Do not exceed a total of 25 feet for each length of ductwork run.
General Duct Recommendation Support the flexible duct often to prevent sags or bends. Stretch the duct to make for a smoother interior with 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.

Inspection and Start-up Checklists Receiving and Inspecting Unit received undamaged Unit received complete as ordered including accessories Handling and Installing Unit mounted on solid level surface Sufficient space allowed for access to unit and accessories.
Starting Up and Operating the Wine Guardian Now that the installation is complete, it’s time to start the unit up. Check to make sure all ductwork and electrical connections are secure. Replace all panels that were removed during installation. Check that all of the openings in the unit are covered with a blank a panel, 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.
Cycling the Unit The fans continue to free-wheel for several minutes when the unit cycles off. This is normal. If the unit is furnished with a low ambient control, the condenser fan also cycles on and off during cooling. This maintains the head pressure on the compressor under low ambient conditions, and is normal. The bottom of the compressor stays warm even when the unit is off to keep the lubricating oil warm and separated from the refrigerant.
Maintenance General WARNING BEFORE PERFORMING MAINTENANCE ON THE UNIT, READ AND UNDERSTAND THE SAFETY INFORMATION CONTAINED WITHIN THE SAFETY CHAPTER OF THE WINE GUARDIAN MANUAL. DANGER HIGH VOLTAGE - RISK OF SERIOUS INJURY OR DEATH High voltages are present in the cabinets. Turn off all power. Use the Lockout/ Tagout procedure before opening panels. CAUTION SHARP EDGES RISK OF SEROUS INJURY Sharp edges are present on the fan wheels, housing, fins and coils.
Cleaning the Filters The condenser coil is provided with a reusable, washable air filter. The filter protects the coil from becoming coated or plugged by dust. Frequency of cleaning the filters is based on the amount of dust or dirt generated in the cellar or basement. 1. 2. 3. 4. 5. Remove the duct collar on the inlet end of the unit. (Optional) Remove the filter covering the face the coil. Wash it under warm water. Shake off excess water. Inspect and clean the face of the coil.
No additional maintenance is required for the heating coil. To test the heating coil operation, set the thermostat on HEAT and set the temperature above the cellar temperature. The supply air temperature should rise above the return air temperature by an amount shown in the specifications. Low Ambient Option The purpose of the low ambient option is to protect the compressor and refrigerant system.
Troubleshooting WARNING BEFORE PROCEEDING, READ AND UNDERSTAND THE SAFETY INFORMATION CONTAINED IN THE SAFETY SECTION OF THE WINE GUARDIAN MANUAL. IMPORTANT This section is intended as a diagnostic aid only. For detailed repair or parts replacement procedures, contact a qualified service company. Check the following table for some solutions before calling a service technician.
Unit is operating and blows evaporator air, but the supply air is not colder than the return air from the cellar Possible Cause Solution Thermostat not set up properly Check thermostat setup on page 37 Compressor not operating High pressure switch open (button up) Alarm will appear on thermostat Condenser airflow is blocked Clean filter and coil (if needed) Remove blockage Head pressure (HP) switch is open Reset HP switch See reset instructions on page 55 page 53 Problems Controlling Cellar Tempera
Problems Controlling Cellar Humidity Humidity too low or supply air is too cold, without optional humidifier Possible Cause Solution Not enough evaporator airflow Remove blockage in supply or return ductwork Check and clean filter and coil Coil frozen – shut off unit for two hours Defective thermal expansion valve If under warranty call for service If not under warranty call a refrigeration technician Raise temperature setpoint at thermostat Temperature set too cold Humidity too low, without optional
Humidity too high when unit is not running Possible Cause Unit needs to run to dehumidify Solution Run unit. Seal openings around doors (gasket and sweep) Humidity too high when unit is running and cooling Possible Cause Too much moisture in cellar Solution Poor vapor barrier installation Humidifier malfunction refer to the humidifier instructions.
High Pressure Switch has Shut Down the Unit Every Wine Guardian unit has a manual reset high pressure switch in the refrigeration system. This switch shuts the compressor and condenser down if the head pressure in the system is too high. It is intended to protect the compressor. Restricted airflow through the condenser is the most common reason for the pressure to become too high. This can be caused by dust covering the filter or an obstruction blocking the airflow in the duct or grille.
Advanced Troubleshooting IMPORTANT This section is intended for qualified refrigeration service technicians only. The technician should repeat all of the previous troubleshooting steps before taking action on these more technical solutions.
