DUCTING OVERVIEW
Use of Ductwork
Use ductwork to connect the unit to the supply and return outlets in the wine cellar. Use only insulated duct-
work to minimize cooling losses, prevent sweating and reduce noise. Use ductwork on the condenser section to
redirect or absorb sound, bring in outside air to the unit inlet, and/or exhaust the hot air.
Note: Do not exceed a total of 25’ for each length of ductwork run
and a total of 50’ combined for both the supply and return lengths.
Avoid crimping the exible ducts. This chokes down the inside area and reduces the airow causing the unit to
operate improperly. Be sure all duct work and outer surfaces in contact with the airow are insulated and have
a vapor barrier on the outside. Un-insulated supply and return ducts may cause bare, exposed metal surfaces to
sweat, further degrading the insulation and equipment cooling capacity.
General Duct Recommendations
•
Provide support for the exible duct to prevent sags and bends.
• 5000tiR Duct Size: 8” Supply and Return
• 8000tiR Duct Size: 8” Supply and 10” Return
• Stretch out the duct to make a smoother interior which reduces air resistance.
• Maximum duct length is 25’.
• For 90° bends, use a 90° adjustable elbow.
• No more than two 90° bends on each duct. Sweep 90° bends are recommended rather than sharp 90° bends.
• Generously apply duct sealant to all metal seams to ll in gaps that can leak air. Allow sealant to dry until rm
to the touch before applying berglass insulation.
• Do not squeeze or reduce the inside diameter of the ducts as this will reduce airow.
• Use short and straight ductwork where possible.
• Check that all fan blades move freely.
• Keep air paths free of loose foreign objects and debris.
• To provide adequate airow the fan speed must be set to high when the unit is ducted.
Location of Supply and Return Grilles
Locate the supply and return grilles inside the cellar to create an airow pattern that maximizes air circulation in
the room. Avoid short circulation of the air.
Do not:
• Install through-the-wall return air grilles at oor level, as they will collect dust from the oor.
• Mount the unit lower than 18” from the ceiling.
• Locate the supply or return air grille where it is blocked by bottles, boxes or cases.
DO NOT ALLOW FLEXIBLE DUCTING TO GET SQUEEZED OR ALLOW THE INSIDE
DIAMETER DECREASE DUE TO VERY SHARP TURNS.
