3. Mounting
•
The unit must be mounted on a floor or slab that is level and strong enough to
support up to 300lb.
•
There are six ½” bolts required to secure the unit base.
•
There is a gravity drain system used, so the unit shall be installed level or with
a slight slope downward the drain connection and the drain line shall be
installed slope down toward the drain.
4. Temperature Controller and Air Probe
•
The temperature controller can be mounted inside or outside the wine cellar,
but the air probe must be located inside the wine cellar or the return duct.
•
The air probe shall be located in the wine cellar 5 ft above the floor or the air
return area, but it shall not be located in the air supply area or other areas
where air is not circulated.
•
Air probe can be pulled out of the temperature controller around 5 ft; if
additional wires are needed, 18 gauge wires may be used to extend the air
probe.
•
If the air probe is installed in a return duct, the evaporator fans shall be
running all the time. Meanwhile due to the temperature differential the
temperature, air probe calibration should be used in order to maintain the
proper wine cellar temperature.
5. Insulated Duct and Drain Line Installation
•
Secure the ducts with conduits to the cellar exterior walls and make sure they
are not curled, twisted, bent and clogged.
•
Hook up the drain line. If rise-up of the drain line is needed, a condensation
pump must be used.
