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.
4.
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.
5.
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.
6. 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.
