Accessories/Options
Electric Heat
The electric heating option is factory installed and includes primary and secondary over-
temperature protection devices per UL and NEC.
Extreme Climate Protection
This bundle includes both a factory-installed Low-Ambient-, and a factory-installed High-
Ambient upgrade. Low-Ambient protection 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, including a 3R
Condenser Fan. We recommend this bundle if the system will experience condenser
inlet temperatures below 20°F (-7°C) or above 115°F (37°C) to protect the system itself.
This bundle will protect the system from temperatures as low as -20°F (-29°C) or as
high as 115°F (52°C)
