INTRODUCTION Customer Service Thank you for purchasing a WhisperKOOL cooling system. We strive to provide the highest quality products and the best possible customer service. If you have any questions about your system, please call us at 1-800-343-9463 or visit WhisperKOOL.com. Using the Manual This Owner’s Manual is intended to assist in the proper maintenance of the cooling system.
RECEIVING & INSPECTING THE SYSTEM Receiving and Inspecting the System • Lift only at the designated hand hold locations on the shipping container or fully support the unit from • • • • underneath. A shipment may include one or more boxes containing accessories. Inspect the packaging for any obvious signs of damage or mishandling before opening the container. Note any discrepancies or visual damage on the Bill of Lading before signing.
BEFORE YOU START 1. Inspect the system before installation. If damage is found, please contact your distributor or WhisperKOOL Customer Service at 1-800-343-9463. 2. The condensing unit requires a dedicated 115 volt 20 amp circuit. Use a surge protector with the unit. Do not use a GFI (Ground Fault Interrupter) line. 3. It is REQUIRED to install a drain line to remove condensation from the evaporator unit. 4. The system is intended for use in properly designed and constructed wine cellars.
PREPARING THE WINE CELLAR The performance and life of your system is contingent upon the steps you take in preparing the wine cellar. Note: Improperly preparing your enclosure or incorrectly installing your unit may cause unit failure, leaking of condensation, and other negative side effects. IT IS HIGHLY RECOMMENDED THAT YOU OBTAIN THE ASSISTANCE OF A WINE STORAGE PROFESSIONAL.
Unobstructed Airflow Unobstructed airflow to and from the system is critical for the system’s overall performance and life span. A minimum three-foot clearance (five-foot is ideal) area is crucial. The air blown by the fans needs to circulate and either dissipate or absorb heat from the space. The system will operate more efficiently with a greater amount of air to exchange. Note: Avoid attempting to camouflage the unit. This will restrict airflow, and thus the system’s ability to work efficiently.
Ventilation The necessity of dissipating heat away from the condensing unit is critical to the performance and cannot be overstated. As the system operates and cools, a greater amount of heat is generated on the condensing side of the system. Adequate ventilation is required in order to dissipate heat away from the condensing unit. If ventilation is inadequate, the exhaust will heat the area or room and adversely affect the system’s ability to cool.
PREPARING THE INSTALLATION LOCATION Minimum Tools Needed: T-Square Hammer Phillips Head #2 Screwdriver Saw Locate the desired installation location. Using a stud finder, locate the ceiling joists on either side of the center point. Cut and frame an opening in the ceiling measuring 14.5” x 36”. Make sure the framing is sufficient to support the weight of the cooling unit. It is highly recommended to use only the mounting locations provided.
