 Ducted Installations – Front Duct Kit
1. Remove the front grill (if present) from the front of cooling unit before
attaching the front duct hoods.
2. Ductwork must be attached to BOTH the intake and exhaust openings,
connecting the cooling unit and the wine cellar.
3. The front duct kit includes two duct hoods. One hood is designed for intake
and will cover the lower portion of the cooling unit. This hood is completely
open on the rear. The second hood is designed for the exhaust and will
cover the top portion of the cooling unit. This hood is partially closed on the
rear. Both hoods are designed to attach to the cooling unit with 3/8” self-
tapping screws (included in the kit). SCREWS LONGER THAN 3/8” MAY NOT
BE USED.
4. A bottle probe is included and is required for use with the front duct kit. The
bottle probe is designed to plug into the face of the cooling unit and
terminate inside the cellar. The bottle probe may be used to measure air or
liquid temperatures inside the cellar. If measuring air (recommended),
simply place the probe on one of the racks. If measuring liquid, the probe in
a bottle with water and rubbing alcohol (10-20%), use the rubber stopper to
seal the bottle, and place the bottle in the racks. If the bottle probe is used
to measure air temperatures, the differential (HY) on the cooling unit should
be set to “4”. If the bottle probe is used to measure liquid temperature, the
differential should be set to “1”. To change the differential on the cooling
unit, please refer to our “Advanced Operation” instructions in Section III.
5. The unit is capable of operating up to 50 equivalent feet for each duct.
Elbows or bends will reduce this length. Use a duct sizing program to
determine the total equivalent feet of a specific duct routing design, or
consult the manufacturer for recommendations.
6. The “High” fan speed setting is required for long duct runs and as ambient
temperatures rise. The “Low” fan speed should never be used in a ducted
application.
7. Condensation on the hood can occur in warm and humid environments,
even though the inside of the hood is insulated. If left unattended, this
condensation may cause damage to the electrical components inside the
cooling unit. This damage is not covered by the cooling unit’s warranty.
If condensation occurs on the front duct hood, you should do the following
ASAP to mitigate the condensation:
- Insulate the duct hood by adhering insulation to the outside of the hood.
- Apply silicone caulking to the seam where the hood meets the cooling
unit
