General Overview
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 though with reduced efficiency. Warm water increases the
capacity of the humidifier to evaporate the water as it passes through the pad. The

8
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.
Additionally, to insure adequate wetted surfaces and to help flush away excess
minerals, the water flow is set to always have a flow of water to the drain. When
operating, the humidifier will use approximately 1 to 2 gallons (4 to 8 liters) of water per
hour depending on the water pressure in the building. About 60% of that will pass
through and go out the drain. There is a strainer and an orifice in the line to restrict the
flow of water, but a throttling valve may be needed to keep too much water from going
to the pad. All that is needed is a steady dripping of water out of the drain to ensure
adequate wetting and flushing of the pad media. Excess water does not negatively
impact the humidifier’s operation but neither does it contribute to more humidification.
The drain volume is too much for just a bucket. A gravity drain line should be piped to
an open floor or sink drain, or a condensate pump may be used where a gravity drain is
impractical. This excess drain water can be discharged directly onto the ground. The
discharge of the drain can be combined into the condensate drain from the cooling unit.
The humidistat, located in the cellar, will automatically turn on the humidifier whenever
the cellar humidity is below the set point and turns it off when the cellar humidity
reaches set point. The recommended setpoint is 55% RH for wine cellars. This humidity
level is high enough to prevent corks from drying out and low enough to prevent mold
from forming. When the humidifier turns on, the water solenoid valve opens, and the fan
turns on. When mounted and connected to a Wine Guardian cooling unit, the humidistat
also controls the main fan to circulate air to and from the cellar.
CAREFULLY FOLLOW THE INSTALLATION INSTRUCTIONS INCLUDED WITH THE
HUMIDIFIER. REFER TO THE MANUFACTURER’S INSTRUCTIONS CONTAINED IN
THE BOX FOR THE HUMIDISTAT. WE RECOMMEND YOU KEEP THESE
INSTRUCTIONS IN A FOLDER ALONG WITH THIS GUIDE FOR FUTURE
REFERENCE.

installed.
Pre-Installation
HUMIDIFIER MAY NOT BE INSTALLED WHERE IT MIGHT BE EXPOSED TO
FREEZING TEMPERATURES. IF THE COOLING UNIT IS MOUNTED OUTSIDE, THE
HUMIDIFIER WILL HAVE TO BE MOUNTED IN THE SUPPLY DUCT TO THE
CELLAR INSIDE THE BUILDING OR MOUNTED AS A FREESTANDING UNIT
INSIDE THE CELLAR.
To check for any possible non-visible shipping damage, you may wish to test the unit
before installing it. To do so, remove the unit from its packaging and set it on any sturdy
level surface. If your humidifier is a freestanding unit, plug in the unit. If the unit is to be
connected to a cooling unit, you need to wire the humidifier to the cooling unit and the
cooling unit must be turned on (Refer to page 14). Set the humidistat above the room
humidity. The unit should now come on. The water solenoid should open, and the fan
should come on. Listen for any unusual noise or vibration. Change the humidistat’s set
point below the room’s current condition and the unit should turn off.
NEVER MODIFY THIS EQUIPMENT. CHANGES OR MODIFICATIONS MAY VOID
THE WARRANTY, CAUSE DAMAGE TO THE EQUIPMENT, AND/OR CREATE A
SAFETY HAZARD.
