Directory of Terms
Ambient Air –The surrounding area outside the cellar such as a room, basement, garage or
outdoors.
BTU/H –British Thermal Unit per Hour is a unit of heat measurement. For example, one ton of
cooling equals 12,000 BTU/H.
CLS –Cubic liters per second. A unit of measurement for the amount of air handled by the fan.
CSA –Canadian Standards Association
Condensate / Condensation –The water formed out of the air when it is cooled below a certain
temperature (called dew point). Often referred to as “sweating” on pipes and cold surfaces. This
water collects at the bottom of the evaporator or cooling coil and drains out of the unit through
the drain line.
Condenser (Heat Rejection) Section / Coil –The Condenser Section uses the compressor,
condenser coil and fan to remove heat from the refrigerant to the ambient air outside the wine
cellar. The word condenser refers to the condensation of the refrigerant from gas to liquid phase.
CE–Certificate of European conformity
Exhaust Air –The air leaving the evaporator or condenser section of the Wine Guardian unit.
Evaporative pad –the wire mesh pad inside the humidifier that becomes coated with water as the
water drips down by gravity. Air being drawn over the pad by a fan causes the water to evaporate
into the air, increasing its moisture content.
Grille or Diffuser –Inlet or outlet plates to direct the airflow or protect the inside of the unit
Humidistat –an electrical instrument that measures the relative humidity of air and
reads in percent (%).
Humidity –relative humidity is the percentage of moisture in the air relative to the maximum
amount of moisture the air could hold at any particular condition. Relative humidity is what is
most widely used and is what a humidistat measures. For example, 100% relative humidity means
the air has as much moisture as it can possibly hold at that temperature. Absolute or specific
humidity is the specific amount of moisture (usually measured in grains of moisture per point of
air) in the air at a given air condition
Heat Gain / Loss –The amount of cooling or heating expressed in watts transferred between the
wine cellar and the ambient space. The Wine Guardian must offset this load.
Moisture –water that has been evaporated into the air.
NEC –National Electrical Code
Recovery –the amount of cooling or humidifying required to return the cellar to its set point
temperature or humidity after some new load has been introduced, such as people in cellar or new
cases of warm wine coming in.
Return/Inlet Air –the air returning from the cellar and entering the evaporator section of the
Wine Guardian unit. Also the air entering the condenser section.
Set point –the desired temperature or humidity that is set on the Thermostat or Humidistat.
SP –static pressure. Unit of measurement (in inches of water column) of the pressure of the air
being handled by the fan.
Supply/Discharge Air –the air leaving the Wine Guardian unit and going into the cellar from the
evaporator section. Also the air leaving the condenser section.
UL –Underwriters Laboratory

Introduction
Dear Customer:
Congratulations and thank you for purchasing a Wine Guardian®Humidifier. We believe
it to be the best wine cellar humidifier on the market and hope that you will agree.
This guide is intended to help the installer and owner of the Wine Guardian Humidifier to
properly install and maintain the equipment. In order to ensure optimal performance, the
equipment should be installed properly and have proper care and maintenance. Please
read this guide carefully, especially the safety instructions, and keep it for future
reference.
Receiving, Unpacking and Inspection
This Wine Guardian Humidifier is shipped in a cardboard box. Each humidifier is factory
assembled and tested prior to shipment. There are three models of the Wine Guardian humidifier.
See 50 & 60Hz part numbers in the table below.
•Freestanding humidifier supplied with its own grille. This freestanding humidifier is to be
used in a wine room with a Wine Guardian system.
•Freestanding humidifier supplied with its own grille, power cord and humidistat. This
freestanding humidifier is to be used in a wine room without a Wine Guardian system.
•Integrated humidifier that mounts directly to the side of any ducted or split Wine
Guardian system. Humidifier is controlled by the Remote Interface Controller via
communication cable.

Upon receipt and before opening the container, inspect the packing crates or boxes for obvious
signs of damage or mishandling. Write any discrepancy or visual damage on the bill of lading
before signing.
Find the packing slip and check for completeness of contents. Make sure it is the correct model
you ordered, including factory options and accessories.
Your Wine Guardian Humidifier has a communication cable that gets wired directly to the side
of the Wine Guardian unit, a drain line that requires piping to an open floor drain or condensate
pump and water fill line.
Inspect all equipment for any sign of damage or loose parts caused during transit. Immediately
report all visual or concealed damage to the carrier and file a claim.
NOTE: If this procedure is not followed, the shipping company may reject the
claim and the consignee may suffer the loss. Do not return the shipment to
the factory.
The Freestanding Humidifier (part No. 99H0185-00 and 99H0185-01 for 60Hz/ 99H0186-00 and
99H0186-01 for 50Hz) ships with a humidistat that must be mounted within the wine cellar, a
power cord with transformer plug, a water fill line and water drain line.
General Description
The Wine Guardian Humidifier is a self-contained unit designed specifically for wine cellars. It
has been designed for easy installation and operation, either as a freestanding unit or mounted on
a Wine Guardian cooling unit. Wine Guardian uses a humidistat to sense and control the amount
of moisture needed to be added to the cellar. Humidifiers are not intended to remove moisture,
only add moisture. All components are of a high quality, standard commercial grade. The
humidifier, depending upon model, operates with 24-volt power or digital signal from the Wine
Guardian control panel, and therefore does not require UL or CSA approval. All wiring complies
with NEC.
Wine Guardian Humidifiers are the evaporative drip pad-type. Air from the cellar is drawn over
a distribution pad that is saturated with water from a distribution tray. As the air passes through
the pad, it absorbs moisture through evaporation of the water. This raises the humidity of the
leaving air that returns to the cellar. Warm water is recommended for use with the humidifier
(105°F - 40°C max.), however the system will work using cold water. Warm water increases the
capacity of the humidifier to evaporate the water as it passes through the pad. The warm water
also leaves fewer solids on the surfaces of the pad and flushes contaminants out of the pad.
Excess water is collected in the bottom trough and exits through the drain.
To avoid build-up of mineral deposits on the pad and potentially causing blockage of the air
flow, it is recommended that hard water be treated (filtered and softened). Install a 5- or 10-
micron in-line water filter ahead of the humidifier to keep dirt from fouling the inlet screen and
the evaporation pad inside. If the water has a high mineral content, a softener may be needed to
prevent excessive scale from building up too rapidly on the pad.
