How to Install the Cooler for Your Wine Cellar

A simple two-step installation

The installation of the CUBE°LT is carried out in two stages. The first is done just before the walls are closed, that is to say that communication cables, conduits and a nailing bottom are installed to ensure the proper functioning of the cooling system.

Step 1

Preparing the location

The materials used for the first stage of the installation are insulated PEX*, it is a flexible and easy to install material. This makes it possible to efficiently link the different units together.

Step 2

Turning on the system

The second step is much simpler. It is simply the start of the complete system.

* If you wish to use a different type of ductwork during installation, contact The Wine Square to determine which product is best suited. Also refer to your industry or building regulations before using plastic conduit such as PEX.

** It is also possible to do the installation in one step in a case of renovation for example. The conduits can be passed in a visible way or through small openings at strategic places to pass the tubes between the wine cellar and the location of the compressor. The use of flexible ducts avoids the complete opening of the walls as when installing the conventional system with copper refrigeration ducts.

Selecting the location

First of all, you need to select where each component will be installed. Although the cooling system pushes cold air when it is in operation, the device works rather to extract the heat: the cold air is only a result.

It's a nuance that seems innocuous, but when evaluating the location of the components, it really comes into its own. Assuming that the system is a heat pump, it is important to consider certain elements.

The water chiller

The water chiller is used to produce cold water for the wine cellar, but it is also the unit that rejects the heat produced by the cellar. It can be installed up to 30 meters (100 feet) from the main unit, in a well-ventilated room and in temperatures of 10°C to 30°C. A room with inadequate ventilation can cause overheating.

The RC4LT

The RC4LT diffuser tends to extract heat from the wine cellar. It must therefore be installed in the hottest place of the wine cellar, the ceiling. Depending on the configuration of the room, the unit will be placed in the center or above the door.

The control box

The control unit can be installed anywhere between the cooling system and the wine cellar. As a rule, it is arranged above the water cooler.

Minimum requirements to ensure the proper functioning

To ensure the proper functioning of the cooling system and to maintain the warranty, it is necessary to build the wine cellar according to the best practices.

Regardless of the size of the cellar, the requirements remain the same. Insulating and sealing a wine cellar are the least expensive and most important elements of a wine cellar. Regardless of the air conditioning system selected, each time your system starts, it mortgages the life of your bottles, so it is essential to ensure that it starts as little as possible.

Installation manual

General

  • Vapour retarder or moisture barrier on all surfaces. This includes walls, ceiling and floor.
  • Airtightness

Ceiling

  • Minimum insulation of R7.5 or U0.13

Glass

  • Minimum insulation of R4.5 or U0.22 with LOW-E protection

Floor

  • Minimum insulation of R7.5 or U0.13

Walls

  • Minimum insulation of R15 or U0.06

Failure to follow these conditions exposes you to condensation on cellar walls, poor humidity control, reduced compressor life, poor wine aging conditions, shutdowns and frequent compressor starts as well as a lack of power to reach the desired temperature.

Also, the insulation present under a concrete slab is not considered as floor insulation, unless the slab of the wine cellar is independent of the rest of the building and has a thermal break of at least 1”. The thickness of the concrete slab acts as a thermal bridge and injects heat around the perimeter of the wine cellar, the exact place where the bottles are normally stored.
