Humidity Control As the temperature begins to drop within the cellar, the relative humidity will rise. The WhisperKOOL units do not create humidity. If you live in a dry area of the country, you may need to add humidity in the wine cellar.
The system includes both the evaporator and condensing units packaged in two (2) separate containers. An exterior housing is required for outdoor installations and will arrive packed separately. Evaporator Thermostat The split system evaporator has been designed to incorporate the Vinothèque PDT ™ series thermostat.
PDT OPERATING INSTRUCTIONS The unit is set at 55°F at the factory. To raise or lower the temperature set point, press the set button while at the same time pressing either the arrow up or arrow down button. WINE Temperature Indicator WINE Temperature SET Indicator Unit ON Indicator...
We have created a typical presentation on “How to Build a Wine Cellar” which is available for viewing on our web site at www.whisperkool.com. Failure to prepare the cellar accordingly will result in the cellar not maintaining proper temperature and humidity.
SPLIT SYSTEM INSTALLATION GUIDELINES General Installation Guidelines and Instructions Vinothèque requires that a certified HVAC technician install and pipe the Split System unit modules. Please take a moment to review State and City building codes to insure the safe and proper installation of the unit.
CONDENSING UNIT SKID PREPARATION Note: The condensing unit is shipped with a protective foam pad/ block to prevent damaging tubing against the condenser coil fins. Please ensure that this pad is removed prior to operation. Condensing Unit -10-...
Head Pressure Control, Low Ambient Control Switch: The switch is used to cycle the condenser fan at low ambient temperature condition. Set the switch to 170 psig for cut-in and 70 psig for the differential. Further adjustment may be needed. Verify the settings via refrigeration manifold gauge and perform the final adjustments to the readings on the gauge manifold.
MOUNTING THE EVAPORATOR UNIT 1. Disassemble evaporator unit. In order to mount the housing to the wall, the internal components will need to be removed and reinstalled after mounting the housing. Remove front cover and thermostat by unscrewing four captive screws located on each corner of the cover and five at bottom of front cover. Note: Thermostat is not plugged into electrical line.
Page 13
3. Identify and remove appropriate knockouts. There are knockouts located on the rear panel, right side panel and on top. Remove knockouts for the two refrigeration lines and install the two grommets supplied. Remove knockout for electrical line. Keep the refrigerant pipes capped to prevent any foreign material from entering, until ready to braze.
Page 14
5. Installing refrigeration lines into evaporator housing. With knockouts removed, install grommets supplied. Install housing, mark location and center line of holes to be drilled in wall. Slide interior into place, measure the distance from the suction and liquid line connection locations to the housing knockout opening. Add that dimension to the length of pipe necessary to penetrate the wall for a rear entry plus enough for an elbow connection if the pipe is to run up or down the wall on the back side of the unit.
Page 15
6. Run the electrical line into evaporator on bottom of left side over insulation. Wires should be at least 36” long going into the cabinet. 7. Re-install interior assembly. Slide interior assembly back into housing gently. Re-attach using the two screws. Flow a small amount of dry nitrogen through the tubing during brazing.
Page 16
8. Attaching refrigeration lines. Line up the piping connections. Energize the liquid line solenoid valve, connect Dry Nitrogen, and adjust to a slight flow through the tubing, being sure no pressure develops in the piping. Connect flare fittings if a flare fitting model, tighten securely, braze other fittings, leak check, evacuate to 200 microns, charge with R-134 refrigerant, start and check out.

9. Electrical wires will need to be approximately 36 inches long. Attach lines according to schematic shown. Power Source 115V 60Hz 10. Install drain line fitting and drain line. Excess moisture in the air will be condensed on the coil fins and captured in the base of the evaporator unit.

11. Install thermostat. Thermostat mounts on the bottom front of the unit. Plug electrical outlet to thermostat and mount from underneath with screws supplied. 12. Install front cover. 13. Energize unit. Note: Thermostat has a 5 minute time delay. -18-...
Refrigeration Lines inch O/D copper “liquid line” and a ½ inch O/D copper “suction line” connect the two units. The refrigerant drier and sight glass shall be installed in that order in direction of refrigerant flow in the liquid line between the condensing unit and evaporator. Enclose the suction line in a cellular insulation ½”...
Maintenance The WhisperKOOL system is designed to operate with very little maintenance required. Do check the condensing unit and evaporator coils, and vacuum them every three months. (by Certified HVAC technician)
Please make sure that you have the following information available before you call: • The model and serial number of your WhisperKOOL unit. • Type of thermostat used with your WhisperKOOL. • Location and installation details, such as ventilation, construction, and size of room.
TROUBLESHOOTING Fault Cause Water leaking from unit 1. Condensate drain clogged 2. Evaporator coil frozen 3. Drain line improperly installed Wine cellar temperature above thermostat set point 1. Large quantity of warm wine placed in cellar 2. Wine Cellar Door left open for long period.
