How cold can the temperature be where the cooling unit is installed?
A: For installations in environments below 40°F down to 20°F, we recommend adding our compressor heater (P/N 1727), which is included as standard equipment on all outdoor units. Below 20°F, in addition to the compressor heater, we recommend adding our fan cycling switch (P/N 6972)
How do I choose between top exhaust versus rear exhaust? What about the fresh air intake? What about the fresh air intake?
The fresh air intake will always come from the rear of the cooling unit. On 1800 Series cooling units, the hot air exhaust can exit from the top or the rear. Choose whichever location has sufficient space to accept the exhausted air. If you plan to duct the hot side of the cooling unit, then the hot air will need to exhaust from the rear.
Does the unit really need a dedicated circuit?
A: First, the background. Unlike our competitors, we build our cooling units with precision expansion valves, not cap tubes, which means that our cooling units aren't limited to a 30°F differential between the desired cellar temperature and the ambient temperature. Cooling systems with expansion valves are much more precise than cap tubes, and much more sensitive to low voltage conditions, which is why our units require dedicated circuits. When we say "dedicated circuit", we mean that the circuit shouldn't have any items that require heavy draws of electricity - eg other appliances, vacuum cleaners, big-screen TVs, blow-dryers - on the same circuit as the cooling unit. Lighting, computers or other low-draw items shouldn't be a problem on the same circuit.
Can the cooling unit be located in a remote location and ducted to/from the wine cellar?
A: These cooling units can be installed above the wine cellar when used with our front intake hood.
Does the unit need to be installed through the wall, or can I install the entire unit inside the cellar?
A: These cooling units can be installed completely inside the wine cellar when used with our rear duct kit (P/N 1439), which allows rear supply and return airflows from a temperature controlled environment OUTSIDE the cellar to be ducted (with insulated ducting to minimize heat transfer inside the cellar) up to 100 equivalent feet (50 feet per duct).
What if I don't have sufficient space behind the cooling unit for the hot air exhaust to dissipate?
A: The rear of the cooling units can be ducted to another location by using our rear duct kit (P/N 1439), which allows rear supply and return airflows from a temperature controlled environment OUTSIDE the cellar to be ducted up to 100 equivalent feet (50 feet per duct).
Do I need the condensate drain line?
A: If you are using the cooling unit in a sealed cabinet, you probably don't need the drain line. If you are using the cooling unit in a cellar, we recommend the drain line, which can be drained inside (bottom) or outside (rear) the wine cellar. Choose the 100W heating element to reduce drainage as it helps to burns off excess condensate before it reaches the drain line.
