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 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 7.3 metre 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 which 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 50°C. 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 220/240 volt electrical outlet.
Humidifier and Humidistat
Another popular option for the Wine Guardian is a humidifier. It comes with a sheet metal adapter
box and a pre-wired humidistat. The humidifier is available for field installation and can be
retrofitted onto an existing unit. Each humidifier is furnished with an electronic digital humidistat
to control the humidity in the cellar. The humidifier mounts directly onto the Wine Guardian unit
and uses the common drain. The humidifier requires a HOT water supply and no additional
external power.
CAUTION
CAREFULLY FOLLOW THE INSTALLATIONS INSTRUCTIONS INCLUDED WITH THE HUMIDIFIER. REFER TO THE
INSTRUCTIONS CONTAINED IN THE BOX FOR THE HUMIDISTAT.
