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 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.
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.
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.
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 no 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.
Wiring the Unit for Power DANGER ELECTRICAL SHOCK HAZARD RISK OF SERIOUS INJURY OR DEATH The electrical outlet and wiring installation must meet the national and local building codes. DO: Match the electrical outlet to the plug provided on the Wine Guardian. Provide dedicated circuit and wiring for the 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 on the following page. Serial No. Model No.
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.
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) Fig. 2 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. Fig. 3 4.
Installation of the Wine Guardian Remote Sensor 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. Mounting the remote sensor 1. Disconnect the communication cable from the side of the Wine Guardian unit and the remote sensor.
4. 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. (Fig.3) Fig.3 5.

Installing the Ductwork Use ductwork to connect the unit to the supply and return outlets in the wine cellar. Use only insulated ductwork to minimize cooling loses, prevent sweating, and to reduce noise. Use ductwork on the condenser section to redirect or absorb sound, to bring in outside air to the unit inlet, and/or to exhaust the hot air out of the ambient space. NOTE Do not exceed a total of 7.5 meters for each length of ductwork run.
Uninsulated ducts and surfaces cause bare exposed metal surfaces to sweat, further degradation of the insulation and a loss of equipment cooling capacity. General Duct Recommendation Support the flexible duct often to prevent sags or bends. Stretch the duct to make for a smoother interior for less air resistance. For 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.

Starting-up and Operating the Wine Guardian Now that the installation is complete, it’s time to start the unit up. Check to make sure all ductwork and electrical connections are secure. Replace all panels which were removed during installation. Check that all of the openings in the unit are covered with a blank panel, a ductwork connection or a grille. CAUTION Rick of personal injury. Cover all openings of the unit to prevent a hand or finger from access inside the unit. Turn on the Unit Plug in the unit.
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 evaporator and condenser coils are provided with reusable, washable air filters. The filters protect the coils from becoming coated or plugged by dust. Frequency of cleaning the filters is based on the amount of dust or dirt generated in the cellar or basement. 1. 2. 3. 4. 5. Remove the grille or duct collar on the inlet end of the unit. 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 in the manufacture’s thermostat guide Compressor not operating High pressure switch open (button up) (see below) Condenser airflow is blocked Remove blockage Clean filter and coil (if needed) Head Pressure (HP) switch is open Reset HP switch See reset instructions on page 49 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 set point at thermostat Temperature set too cold Humidity too low, without optiona
Humidity too high when the unit is not running Possible Cause Solution Unit needs to run to dehumidify Run unit. Seal openings around doors (gasket and sweep) Humidity too high when unit is running and cooling Possible Cause Solution Too much moisture in cellar Poor vapor barrier installation Humidifier malfunction refer to the humidifier instructions.
High Pressure Switch has Shut the Unit Down Every Wine Guardian unit has a manual reset high pressure switch in the refrigeration system. This switch shuts the compressor and condenser down if the head pressure in the system is too high. It is intended to protect the compressor. Restricted airflow through the condenser is the most common reason for the pressure to become too high. This can be caused by dust covering the filter or an obstruction blocking the airflow in the duct or grille.
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.
