Size And Capacity - Wine Guardian 99H0174-00 Installation, Operation And Maintenance Manual

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% 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.
CAUTION
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.

Size and Capacity

The Wine Guardian Humidifier uses a 10" wide x 11" high x 2" thick (254mm wide x 780mm
high x 51mm thick) expanded coated aluminum pad. Its rated output capacity for wine cellars is
0.42 lbs/HR (0.19 kg/HR) using 100°F (38°C) supply water. Humidifier capacity is rated at wine
cellars conditions of 57°F/55% (14°C). See Figure 2.0 dimensions on page 8.
