Accessories and Optional Equipment

Heating Coils

Heating coils are optional and require no additional power source. The electric heating feature 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 PRO 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 PRO
selected. Follow installation instructions carefully. Poorly or incorrectly installed ducts can degrade
the performance of your unit dramatically.

Extended Compressor Warranty

The Wine Guardian PRO 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 Protection

A factory installed Low Ambient Protection feature is standard on the Wine Guardian PRO units.
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 PRO automatic condensate pump is available to pump the excess
condensate water to a sink or remote drain. It requires a separate 120-volt electrical outlet.

Humidifier and Humidistat

Another popular option for the Wine Guardian PRO is a humidifier. The humidifier is available as
a freestanding unit powered by the Wine Guardian PRO 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
PRO ducted system. The Wine Guardian PRO 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 feature is standard (on DP25 and DP50 models only) that makes the
Wine Guardian PRO capable of exposure to high ambient temperatures. The high ambient feature
consists of high output fan and condenser 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.
