Accessories and Optional Equipment

Heating Coils

An optional heating coil is built-in and requires no additional power source. The electric heating
option is factory installed and includes primary and secondary over-temperature protection devices
per UL and NEC.

Water Cooled Option

A water cooled option is available that uses a tube-in-tube heat exchanger in place of the
condenser coil and fan. Waste heat from the refrigerant is transferred to the water. A two-way
control valve is used to regulate the flow of water to maintain head pressure.

Duct Collars and Flexible Ducts

Ducting for the Wine Guardian is sold in kits by size for each unit. Each kit contains two adapter
collars, one 25-foot length of round flexible duct and two straps. The number of duct kits needed
depends on the layout. The size of the kit depends on the model Wine Guardian selected. Follow
installation instructions carefully. Poorly or incorrectly installed ducts can degrade the performance
of your unit dramatically.

Extended Compressor Warranty

The Wine Guardian uses only the best commercially available compressors on the market. However,
since the compressor is the single most expensive component in the unit, it is recommended that you
purchase the extended warranty option.

Low Ambient Option

A factory installed Low Ambient option is available that makes the Wine Guardian capable of
exposure to low ambient temperatures. This feature controls the condenser fan operation based on
head pressure and heats the oil reservoir. The Low Ambient Option (LAO) is recommended
whenever the condenser section is exposed to air temperatures below 40 degrees F. This can occur
if the unit is placed in a garage or under an outdoor canopy, or if the unit is located inside a heated
space but the condenser air is ducted in from the outside.

Condensate Pump

An optional Wine Guardian automatic condensate pump is available to pump the water to a sink or
outside. It requires a separate 120 volt electrical outlet.

Humidifier and Humidistat

Another popular option for the Wine Guardian is a humidifier. The humidifier is available as a
freestanding unit powered by the Wine Guardian system, as freestanding unit with its own power
cord and humidistat or as an integrated unit that bolts to the side of any Wine Guardian ducted
system. The Wine Guardian humidifier requires a water supply and drain for operation.
CAREFULLY FOLLOW THE INSTALLATIONS INSTRUCTIONS INCLUDED WITH THE HUMIDIFIER.
REFER TO THE INSTRUCTIONS CONTAINED IN THE BOX FOR THE HUMIDISTAT.

High Ambient

A factory installed high ambient option is available (on D025 and D050 models only) that makes the
Wine Guardian capable of exposure to high ambient temperatures. The high ambient feature consists
of high output, fan condenser, and fan and coil. The high ambient option is recommended whenever
the condenser section is exposed to air temperatures above 100 degrees F to a maximum of 120
degrees F.
